Yes i get what your saying, i must have been confused slightly with prime lenses.. i have a 60mm nikon which is one of nikons best lenses.. its 2.8.. The high ISO setting on the d3s will work brilliantly with this..

Im also hoping to purchase another 2 high end nikon zoom lenses- so i have good range, including my 60mm..

Im hoping to do a lot more high end fashion, ill hope for the hasselblad one day!! (but we’ll see how that goes!)

The d300 is a good camera- but ive been using low end stock lenses on it sadly, so the response time is quite slow, especially in low light- any higher than ISO 800- and i run into problems..

I think i have out grown the camera now, so its time for me to step up now, so i will be purchasing the D3s- CANT WAIT!!!

As far as wedding photography being dominated by Canon, this is just my observance of the current market. I know many wedding photographers that use Canon 5D Mk II as their primary camera and I believe this is due to the historical fact that Canon used to beat Nikon in high ISO performance all the way until Nikon released D3. The situation has been changing recently though and many photographers are either switching from Canon to Nikon, or new pros are emerging that use Nikon exclusively.

As far as “constant 1.8 zoom lenses” – where did you hear that, because there is no such thing as a constant 1.8 zoom lens. Most pro-level zoom lenses are maximum f/2.8 and there is not much difference between what Nikon and Canon offer when it comes to professional zoom lenses.

Where Canon currently beats Nikon, is in f/1.2 primes. Nikon currently does not have any modern pro-level f/1.2 autofocus lenses and Canon has both the Canon 50mm f/1.2 and Canon 85mm f/1.2 lenses that are superb. Hopefully Nikon will release an f/1.2 lens soon to stay competitive on that side, but it is hard for Nikon, because they are a much smaller company than Canon.

As far as your Nikon D300 – I also have one and I love it, even though the performance is not as good as in my full-frame Nikon D700. If you can afford the D3s, I am 100% positive that you will not regret the purchase, because there is nothing out there today that comes even close to its low-light performance.

Hope this helps :)

Im a wedding photogapher. i have been usuing the D300 which is not great. I am now looking to purchase the D3s which i know is a great camera.

You mentioned that the wedding photography market has been dominated by canon.. Why is this? I did hear that they have constant 1.8 zoom lenses. Is this why? Correct me please if i am wrong.

I have been well informed that Nikon cameras are very reliable in comparison, hence the reason why i bought the d300 a year ago..

Now looking to purchase a full frame camera, and im very comfortable with Nikon Body. The D3s is an amazing camera
