A very nice article, I enjoy it just as your other articles.

Here I have a question: could yopu tell me what is the proper way to clean a polarizer filter? I have a Kenko CPL filter. Recently I tried to clean it in a way just as cleaning a normal camera lens, but some colorish smear marks of the lens cleaning solution on it. The I used a microfibre cloth and breath to clean the marks but I could not get the marks completely away. I searched the internet and found that this seems to be a common problem and I could not found a “correct answer” on the net. Some people suggested to use a lenspen, but some other people claimed that a lenspen will also leave some smear marks on the CPL filter. And, I have a FilterKlear™ LFK-1 lenspen and in the instruction it is written that “Do not use Lenspen® FilterKlear™ on polarizing filters or on wet surfaces.” Could you tell us how you clean your CPL filters?

Thanks,
Frank

I am wondering if you will do a photography tips for ND filters. thanks.

i just want to ask if the polarizing filter will be fine if i take photos on people with a landscape background..?

what will be the effect if i use a polarizing filter to take photo of people?

how about indoor..? with flush and without flash condition..?

thanks in advance..

I own Canon 7D and have a kit lens 18-135 mm. I need to make some modeling shoots for my friend, so i’m getting Canon EF 50mm f/1.8 II Lens and it will be used outside. Do you think Hoya lens for the 50mm lens would suit me well? or you have other recommendations? I have a limited budget.

Best Regards,

I own a D90 with 18-105 and 35mm Nikkor lens. Reading your blog, I’m thinking of buying CPL for 18-105 mm lens now. I looked through the B+W CPL filters. It costs so expensive ($140) and I’m just a student!!! I found a review on CPL filter and learned that Marumi filter would also be compatible and twice as less expensive ($70) than B+W. Hoya would also another 25$ cheaper than B+W. I wonder that these three brand make much different? Have you heard about that?

One more question, I already have a NC Nikon filter for both lens. Do I need to switch from CPL filter to NC filter when I take a photo indoor? Would a CPL filter make photo darker indoor?

Thanks
