Customer Reviews

Polarized Lens
I am not 100% happy with this purchase. My understanding was that the lens was supposed to make the colors vivid. What I found was that while some colors were enhanced, the overall photo was dark.

verdict still out on this ...
Maybe I just don't get it. This Polarizer works differently from previous circular polarizers I have owned. Sometimes it works and the results are dramatic, however most of the time there is no polarization even though conditions dictate that there should be. It is advertised to work w/ a 24-105MM lens which is what it is attached to, however I still get vignetting at the 24mm setting. Expensive lens protector at this point.

Great filter, but...
If you have quality glass, like the Canon L series, then you need quality filters. the B+W are made from ground optical glass, not a piece of plain glass like as you see in the tiffen and hoyas filters (even the expensive ones are still cheap grade glass). Only B+W and Heliopan put the time and $$ into making filters that are designed to be used with your quality lenses and not distort and reduce the optical quality of them. I have 2 MRC, 1 Kaesemann, and 1 slim one, and I love them, HOWEVER the slim one you cant put a normal lens cap on it, and that is a major pain!! I have a Heliopan as well, and I prefer the B+W a little bit more as its a brass ring and not aluminum and thus does not bind up as easy, and thats important when you want to change filters quickly! But the Heliopan slim model you can still put a normal Canon lens cap on it, as I have done it many times on my 17-40mm F4 L series lens before I got the B+W. If you use a cheap filter on a pro grade lens, you are wasting your money, on the lens and the filter as the filter just hurt your image quality, and thus you lowered the quality of your lens! In filters, like lenses, you get what you pay for!!!

I shoot in all kinda of weather conditions, from sunny and warm, to windy and cold or snowy, and I have never had any major issues with any of my B+W filters acting up! I prefer the MRC or even the Kaesemann over the entry level one, but even their entry level one is ground glass, so you still get a great quality filter at that price point.
