Nikon D300 vs D90 high ISO noise comparison

I decided not to do another feature comparison of Nikon D300 vs D90 like I did in the D300 vs D80 review. Just type "D300 vs D90" in Google and you will find a lot of good articles on feature comparisons.

What I will concentrate on, however, is the high ISO noise comparison in a low-light environment. I ran two quick tests - one with an external flash and one without. Both tests are performed on a sturdy tripod, with timed exposure to prevent camera vibrations. Both Nikon D300 and Nikon D90 were set exactly the same way, shot in manual mode with Nikkor 50mm f/1.4G at f/5.6. Exposures were exactly the same in both cameras, depending on ISO value. Shot both in RAW (Active D-Lighting off, High ISO NR Normal), then imported into Lightroom, cropped and exported with "Camera Standard" camera profile. The rest of the data is available via EXIF on the files to those who are interested in technical details.

Note:

  • "Test 1" is 100% crop of the original image without using flash. Center focus on the house under "Pepperidge Farm"
  • "Test 2" is 100% crop of the original image with an external flash on a shoot-through white umbrella. Center focus on the right eye of the doll.

Conclusion:
As expected, both Nikon D90 and Nikon D300 produce almost identical results in ISO 200-800. Seems like the on-camera image processing is identical for this ISO range. However, starting from ISO 1600 and above, I noticed that D90 performs a little better in controlling noise. Looks like Nikon is using a different method of on-camera noise reduction on D90. My main purpose of this test was to test whether D90 images are sharper in higher ISOs than D300, as claimed by Ken Rockwell in his ISO 3200 comparison tests. I can now conclude that Ken Rockwell's D300 definitely has focusing issues, since I did not see any sharpness differences between both cameras in my tests. In fact, I think D90 actually applies more noise reduction than D300, resulting in less noise in higher ISOs. Look at ISO 6400 - D90 grains look "squished" together (which typically happens because of more aggressive noise reduction), while D300 is showing more "normal" grain.

Other notes:

  • D300 has a problem with over-exposing shots in matrix metering mode. D90 does not have this problem and seems to behave much better. I would recommend setting the exposure compensation switch to "-0.3 or -0.7" on the D300 to get proper exposure.
  • I noticed that the images from D90 on "Test 2" look a little less sharp compared to D300 (look at the doll's eyelashes). This might be due to a slight back-focus issue on the D90, but could also be due to the fact that D90 is physically lower than D300. I did not adjust the tripod while changing the cameras, so the focus could have shifted a little on D90.
  • I have not posted full images of D90 and D300 from the above tests because the files are too big.
  • The above tests only demonstrate camera capabilities in two different conditions. Other people might get different results, depending on light conditions, camera settings, etc.
  • If you want to retain the best image quality, I would not recommend using ISO levels higher than 800 on either D90 or D300. Sometimes I might use ISO 1600 if the light conditions are poor, but anything beyond that impacts the sharpness of the image. Even noise reduction software won't do much help at ISO levels higher than 1600.
  • I did not have a chance to test the video capabilities of the D90. I know a lot of people are looking forward to this feature, but I wouldn't get too excited about it. The camera won't auto-focus in video mode and there are limitations and known issues with video on D90. Hopefully the next generation DSLRs will have better video mode functionality.

  1. Great job. Currently looking at both models. Expect to shoot alot in poor light, so it looks like I will lean toward the D90.

  2. Thanks a lot! I have had so much distress wheter I should get the d90 or the d300 but now I have decided for the d90. I will afford more lenses since the camera is a bit cheaper.. And it is not bad that it seems to be slightly better in high isos than the d300 either!!

  3. Thanks,I decided to buy D300 but now it seems that I most have a revision.

  4. Interesting. Yes, I also noticed that the d300 seemed sharper around the eyelashes.
    For those that are “leaning towards” the d90, be careful… they’re both great cameras, but don’t be too quick to buy the d90 simply because of the hi-iso… the d300 does have a few other features that the d90 doesn’t…

  5. Raph,

    I fully agree with you – as I stated above, D90 applies more noise reduction than D300, which does result in somewhat “softer” images. D300 is definitely sharper because less aggressive noise reduction is applied, which is easy to take care of during post-processing in Photoshop.

    And yes, D300 has features such as professional focus system that D90 doesn’t.

    To everyone else:
    If you are buying your first DSLR and want something more advanced than the entry-level D40/D60 line, then go with the D90. If you already have D40/D60/D80 and want to move up, you might want to check out both D90 and D300 and decide what features are important for you. For lots of action and moving wildlife (birds, etc), I would still recommend D300 over D90 because of its 51 point AF system. For every day and family photography, I would recommend the D90.

    However, I wouldn’t be too concerned about the camera body and would focus on lenses instead. Remember, glass is to keep, while bodies get updated every two years. Don’t spend too much money on a body, unless you really need it for your photography. I recommend reading my “DSLR Purchase Guide” for first time DSLR buyers: http://mansurovs.com/2008/10/15/dslr-purchase-guide

    Sincerely,
    Nasim Mansurov

  6. Perfect. Clear egde of the D90 over the D300, got myself the d90, it’s just that much more advanced.
    Thanks!

  7. I currently have a D80 and am using a Sigma 170-500mm lens. I take a lot of surf photos at contests and I am very disappointed in the sharpness of the photos, especailly when cropped or enlarged. Can you recommend a lens that I can rely on for distance and sharpness? Should I upgrade to a 300 or D90? I aprecciate any feedback and advice.

  8. Betsy,

    It all depends on how much you can spend on a lens. If you are looking for a lower cost lens with a good range, I would recommend the Nikon 300mm f/4 AFS lens. You can read my review of this excellent lens here: http://mansurovs.com/nikon-300mm-f4-lens-review

    If you have $5K or more, my recommendation would be to get a professional lens such as the 300mm f/2.8 VR or 600mm f/4 VR. These lenses will deliver exceptional performance and they are the best you can get today.

    Nikon D80 is a great body and if you only shoot in bright sunny days, then there is no need to upgrade to D300 or D90.

    Hope this helps.

    Sincerely,
    Nasim Mansurov

  9. The D-90 is a bit better than the D-300 as it stands on the D-80 then the D-300 then the e D-700. The D-90 is not only the D-300 but also the D-3 and D-700.

    The D-90 image is actually better than the D-700 if the sensor was FF.

    I use Ultra Color Lab and have them color correct in Kodak DP2 for 15 cents and it is better than Photo shopped Images.e De D-200 make 40×60″ Prints.

    The D-90 is better than the Nikon D-200 and should have a better color than the Nikon D-300.

    PePhoto can now print up to 150″ They use UP-SIZE and the work is outstanding in Large Prints.

  10. I have bought both of them, the Nikon D40 and the Nikon D300 and I have found that their are both produce high quality images.

  11. Actually I doen’t understand what you really tested:
    “Both cameras … camera profile.”

    Do I read right when I read: “I used manual settings but in software I added the camera optimizations”?

    It would be interesting to post the same pictures uneditted, RAW translated directly to JPEG. Now one keeps wondering what you are comparing:
    - in camera optimizations (D90 should win hands down).
    - software used (many Nikon users don’t have Lightroom or Capture NX).
    - in fact one could ask if you would get the same results if you were comparing JPEG’s directly from the camera.

    Since I do have a D80 and have been wondering about an upgrade I grade the differences in another way. The diff between a D80 and D90 are generally a 10MP CCD vs a 12MP CMOS, a cleaning system and much software. Much of the software is rendered useless if you use RAW. At least, unless you import camera optimizations in your software and unless Nikon does some editting before storing the RAW.

    • Huub,

      I was simply referencing the way I processed the images that were originally shot in RAW. I did not post the RAW files because of their size. Let me know if you would like the RAW files and I will email them to you for comparison.

      I really don’t care about in-camera optimizations (because I shoot RAW), so I didn’t bother to change any of the settings.

  12. Hi,

    Im still deciding between this two. Have been using a d60 for close to a year now and am finding a need to upgrade. My mind was set on d300 all this while not until i started doing some research and comparing it to d90.

    Which should i get/ thanks!

  13. Doug Harper please share your research. From hands on experience, my D300 has higher IQ than my mates D90. My D700 blows my D300 away in peices also.

  14. I’m surprised no one mentioned the xsync speed differences since the d90 only has 1/200 while the d300 has1/250 with a optional 1/320 which I guess isn’t really a big deal unless you shoot things like action sports in skateparks or at night like I do. I’ve been struggleing to decide between the d90 and the d300 for a couple months now it’s so hard for me do pick between the slight high iso advantage to the d90 and thefaster flash sync of the d300. This was taken with 1/200 sync and as you can see there’s a little motion blur on his arms that the 1/250 prob would have eliminated. Choices Choices grrrr.

  15. Can’t wait to buy a D90 body and some good lenses, maybe a 28-70mm f/2.8 and a 50mm f/1.4. Now i have D60 and begin to feel that more focalisation point would worth.Don’t say about lack of bracketing and so on. For now, in my country all photo techs are more expensive than US and rest of Europe…

    • Phlom, good choice! Nikon D90 is a great camera and you will absolutely love it! In terms of lenses, also look into 35mm f/1.8 DX, which is a great lens for D90.

  16. Thanks for your test!

    When we compare RAW images without jpg-compression or noise suppression, the D90’s sensor seems to perform a lot better than D300s’s… which is awkward, as I have read several times that these cameras “probably share the same Sony sensor”.

    Here is the DXO comparison between D90 and D300 at RAW.

    The difference in terms of SNR, tonal range and colour sensitivity are not big, but D90 performs better. The difference in terms of dynamic range is pretty big though (note that a different scale is used for measuring dynamic range).

    I don’t get it – the D300s is the more recent camera, it is way more expensive and its noise performance is worse… why is nikon doing that?

    • NDN, thank you for the feedback!

      Here is what I believe happened with the release of D90 vs D300/D300s:

      1) The Nikon D90’s sensor is very similar to the Nikon D300 sensor, but it is NOT the same. If you pay attention at the pixel pitch, the D90 sensor has a higher pixel pitch of 5.5 vs 5.4 in D300/D300s sensor.
      2) As seen in the above images, the Nikon D90 has a more aggressive noise reduction algorithm while processing images. This results in cleaner images in higher ISOs.
      3) The Nikon D300s sensor is exactly the same as the sensor in Nikon D300. I believe this is where Nikon goofed up a little – they should have used the D90 sensor in the D300s instead. But I understand why this happened – it was cheaper for Nikon to reuse the same sensor as the D300. If they had used a D90 sensor on the D300s, they would have needed to significantly increase (double or triple) the production of the D90 sensor to provide enough sensors for both the D90 and the D300s bodies.

      This is why there is a difference in image quality between D90 and D300/D300s.

  17. Thanx for your research. It helps me making wise decision. With that I’ve already upgraded my D60 to D90. Worth the money spent. Thanx again.

    • Nadzri Mohd, congratulations with your new purchase and I’m glad that found my article useful.

      You will love the Nikon D90 and I’m sure that it will serve you well :)

  18. Dear Nasim,

    I am a D40 user since past 2 years. 18-55 Nikon (Standard lens with the body) and Sigma AF 70-200. I generally do a lot of wildlife photography. Blog http://www.varunvisions.blogspot.com (if you have time please visit, any comment would be highly appreciated).

    Now I am planning to shift to a better version of Nikon family D90 or D300. The problem I face with D40 is that after dusk my camera is of no use, image quality is null.

    My question is firstly, should I buy a D90 or D300? Secondly, if I buy a D90 should i buy a tele converter to go with my Sigma lens or is there any lens you can recommend? Of course budget is a issue. Photography is my hobby not my Bread and Butter.

    Kindly enlighten me. You can also mail me on varunspatil@gmail.com.

    Thank You,

    Varun Patil

    • Varun,

      I suggest to go with the Nikon D90 and invest in a good lens instead. The Nikon D90 has a slightly better sensor than the D300. If you do not need the speed and other pro features, the Nikon D90 is a superb camera.

      As far as the lens, if you need an affordable lens with a good reach, instead of buying a teleconverter for your Sigma, I would rather recommend getting the excellent Nikon 70-300mm f/4.5-5.6 VR lens.

      Hope this helps :)

  19. I just moved up to the d300 from the d80. Im super excited!

  20. я это всегда говорил что,у D90 мало шумов чем у D300!

  21. Dear Nasim,

    Thank you very much for your input. I know we are on a compare of D300 and D90, but what about the new D300s camera? By the way if you been through my blog did you find it any good.

    Regards,
    Varun

    • Varun,

      As far as the sensor is concerned, the new Nikon D300s has exactly the same sensor as the D300. For action/wildlife/sports photography, the Nikon D300s would be a better camera than Nikon D90, because it has the speed. For landscape and other photography where speed is not important, the Nikon D90 would work great.

      Your blog is great and I loved your elephant shot and the beautiful kingfisher. Keep up the good work!!!

      Nasim

  22. Have both the D300 and D90. I never liked the D300 for its low iso noise.Its going on eBay soon.
    No probs with the d90. Also have the D700 and Canon 5D mark II. The are better, but not that much for the price diff.. I´ll stay with DX for the next 2-3 yrs.

    • Paul, thanks for sharing! Yeah, the D90 is a superb camera and I wish it was available when I planned to get my D300 :)

      DX is here to stay. That’s why Nikon keeps on releasing so many new DX lenses every year. I suspect at least 2 DX lenses will be released by Nikon this year.

  23. Well FX and DX are just different paths. I like DX for low weight, smaller lenses, good DOF, low prices, etc…
    I use my Canon 5D2 for landscape, the D700 for portrait. But frankly, the D90 could do 80-90 % of these jobs as well.
    The D90 wont be the last DX camera from Nikon.

  24. ME A STUDENT OF ARCHITECTURE COMPAIRING NIKON D80.D90.D300.CANON EOS 50 D FINALY RECOMEND STUDENTS 4 THE BEST NIKON D 90 ONLY ONE PROBLEM IN THAT IS THE BODY IS VERY LIGHT DIFICULT TO STABILIZE BUT TRUST WORTHY

  25. WOW.. I just read all of these comments and learned so much from everyone. I thank you all so much. I started with the D40 3 years ago, then went to the D80, to the D200. Now I am ready for the next step and from what I can tell it would be the D90. I do weddings, Portraits,Landscape, Freelance and Business Functions occasionally. My buddy is telling me to get the D700 but there is no need for me to waste my money when I do not do any action shots or any high modeling photo’s and I don’t need a work horse of a camera to get the job done right. Am I correct?

    I do how ever want to make the right move and not go backward on my next purchase I want to make a wise move and as I can tell the D90 of the D300’s would be a wise choice. I might also grab a battery grip with that too.

    Please inform me on my thoughts…

    Thank you Tyler

  26. Thank you for a great comparison Nasim!

    I’m getting myself a Nikon D90 :)

  27. Good work on this comparison!
    I have the opportunity to trade a D40 for a used D300 for less $ than what a new D90 will cost me I still need to decide. I’m torn between getting a new D90 or the used D300. I was leaning towards the D90 due to Rockwell’s reviews, your comparison still gives an edge to the d90 but not as bad. I’m really attracted to the D300 autofocus system. The D300 belongs to a friend who doesn’t really use it, I had the opportunity to shot side by side, me with my D40 and him with his D300, while I couldn’t shot any more, he was still getting sharp images in the light available. I often wish the D40 had better iso performance, as well as more focus points. Also often find my self wanting better speed in the D40 when shooting moving subjects, ie: dog running, the autofocus on the D40 can’t keep up, or even the slightest shade will cause blurry images. The plan is to exchange bodies, flash cards, batteries etc … but keep our lenses 18-200 Vr, 35 afs 1.8, the kit 18-55 afs of the D40 , a 70-300 AF, he has another copy of the 18-200Vr. Money wise this will cost less than getting a new d90, altough was unsure due to Rockwell’s review. I know the D300 is in good shape. Would you recommend trading my D40 body for used d300 body instead of getting a new D90? Thanks again.

    • Armando, yes, in your case I would recommend trading the D40 for a D300 instead of buying a brand new D90. You are not only saving money, but you are also getting a faster camera with a better focus system. The difference between D300 and D90 in noise levels is not that big…

  28. Hi, I am using D60 and I have a friend that wants to sell his D200.

    Should I get his D200 or D90?

    Need some advise here :) Thanks!

  29. I enjoyed your review and comparisons, but one thing that I noticed right away in the images of the doll was the difference in color rendering between the D90 and D300 at each ISO level tested. The D90 skin color appears rosier, and the D300 skin color has a more neutral/gray-green cast. Is this simply a difference in picture control variation between the two cameras, or a different method of rendering color between the two models?

    I’m reading this review after reading your comments on the 70-200 vrII. I have a D90 and D300 and my dilemma is this: I’ve been asked to shoot an interview event in June based on images I posted of a similar event last fall taken with my D90 and the 18-200 vr. Although the images are nice at a lower resolution, when viewed at full size on my larger monitor, the chroma noise is terrible. I am wondering which, of a body that handles high ISO noise much better (D700 or such) or a fast lens (70-200 vr), would be the best option for photographing an indoor event. Ideally, I would have both, but I really shouldn’t be affording even one of these. I would like to produce nice, clean images that can be used at at a reasonable size or in print, however, so something needs an upgrade.

    Thanks for your work

    • Marlene, all of the above images were shot in RAW, so the camera picture controls would not have mattered. I just went back and looked at the RAW images again and everything looks identical, including the white balance. It could be that the color tone is slightly different because I was using a spiral bulb – those could sometimes take a while to heat up. But I doubt that the bulb could have caused this, so it might be just the way D90 renders colors. Remember, the Nikon D90’s sensor is NOT the same sensor as in D300.

      As far as whether you should get a camera or a lens for less noise, you should definitely consider the Nikon D700 for low-light situations, because it will have a two stop advantage over the Nikon D90. Your 18-200mm lens is also a big limiting factor, with a maximum aperture of f/3.5. What I would suggest, is getting yourself a prime lens such as the Nikon 50mm f/1.4, so that you could shoot at higher shutter speeds and lower ISO.

      The Nikon 50mm f/1.4 lens works beautifully on the Nikon D700 and overall, you will gain about 4-5 stops of light compared to your current setup. Do you have an external flash? If you do not, then you should also consider getting one.

      So, here is what I recommend:
      1) Nikon D700 Body
      2) Nikon 50mm f/1.4 Lens
      3) Nikon SB-900 flash

      I also highly recommend reading my “Low-light Digital Photography Tips” article, along with my “Corporate Photography” article, which perfectly applies to event photography.

      Hope this helps :) Let me know if you have any other questions.

  30. hi, I enjoyed your review and id like to ask u a question.
    im planning to buy a dslr cam and i cant decide between nikon d90 and d300.
    i intend to use the cam mostly for landscapes, pictures of buildings, people&people portraits, urban life photography mostly. i was thinking to buy the cam and overall lens such as 18-200 mm, but also a macro lens 105 mm both from nikon, in the future i intend to buy a wide lens as well 12-24mm cause now i dont have the budget for all these.
    so, could u advise me please, which cam is better for my purposes d90 or d300?
    i dont consider the money difrence of 700$ bewteen these 2 cams, i rather spend more money now, and be satisfied with the cam for the next 5 years or even more.
    best regards,
    raluca

    • Raluca, looks like you do not need the speed or weather sealing for your photography needs, so I think that the Nikon D90 would be a better choice for you. Spend the extra $700 on a good pro lens instead.

      I personally wouldn’t buy the Nikon 18-200mm lens, because it is not good enough, especially on the long end. If you want to have a good wide to medium lens, get the Nikon 17-55mm DX lens instead. If you think you will move FX in the future, then get the Nikon 17-33mm or wait for the newly released Nikon 16-35mm f/4.

      Hope this helps.

      • yes nasim, it hlped me a lot!!
        if u dont mind, id like to ask u about the 18-200 mm lens.
        i was thinking to buy it cause is very usefull when i travell, u know…. when u travel …u take pictures here and there cause u never know in advance what ull going to shoot next , so i want a lens that allowes me to take pictures while subjects are far or near by. a lens just for vacation purpose, that fits most of the situations.
        could u recomend me please a lens that saves me from changing 2 lenses (while im in a trip), since im not a pro, is not easy for me to manage them so fast, plus, i could loose important moments while changing the lenses?
        thx again for your time
        best regard
        raluca

        • Raluca, you are most welcome!

          As far as 18-200mm lens, I personally had this lens for a long time (over 2 years) and it was just sitting in my shelf gathering dust. I travel a lot and I found that image quality is far more important for me than convenience of just one mediocre lens. I do not mind switching lenses and it only takes 10-15 seconds to do so. Unless you are in a safari with a lot of dust, you shouldn’t worry about switching lenses.

          • yes, ure absolutely right nasim, i reconsidered my point of view thx to your advice and i read more about the 17-55 mm, so decided to take it instead of the wide 12-24 mm and 18-200 mm.
            but now, which lens should i choose to cover the >55mm range? could u give me some hint?
            just DX lens, cause i dont think ill ever buy a FX cam…..it’s too expensive for me since i dont make a living out of the photography…
            ty again and again for your advice, really appreciate it!
            raluca

  31. Hi Nasim,

    I finally bought a Nikon D90. Happy with results from the kit lens. Now I am a bit confused, I do a lot of wildlife, indoor and abstract photography so should I go for a

    1. Tamron AF 18-270mm f/3.5-6.3 Di II LD [IF] Asph. VC macro

    OR

    1. Nikkor AF-S 55-200 VR ED IF f/4-5.6 G
    and
    2. Tamron AF 70-300mm Di f/4-5.6 MACRO 1:2.

    kindly guide me…..which would be better buying a single 18-270 or two different lenses.

  32. can some one sell me a nikon d90 with a fairly good lense all at an attractive price or how cheapest can i get one?

    • Aaron, I fully agree with what Varun said below – be careful about buying a used camera from an unknown source and definitely be careful about online stores that advertise DSLRs at large discounted prices.

      The best stores I recommend are B&H or Adorama.

  33. Dear Aaron,

    Firstly, I personally feel one should always go for a brand new camera, you never know what the secondhand camera has been through. Secondly, D90 is a very good camera (the reviews from other sites including that of Nasim’s say so and even I am using one) so probably no one would be interested in selling their camera.

    The D90 come with a Nikon 18-105mm VR kit lens. You can also buy independent body and some other lens depending on your requirement.

    Rates depends on the region where you are based.

    Everything I said is my view, Nasim is more than welcome to make any improvisation.

    Regards,
    Varun

  34. Don’t get stuck too much with cameras; All D90, D300, D700 are good camears.
    (I own both D300 and D70).

    The lenses are more important and the person behind the camera is the most important.

  35. would you recommend the d300s or the d90 for children’s photography? Any lens suggestions as well?

    Thanks!

  36. ok, ill.
    ty very much for your time and advice nasim.
    keep up the good work!
