i've been using the filter for just a short time now on my efs 10-22 lens on the rebel xt, and it was certainly worth the money. the pictures come out with deep rich colors, beautiful. no vignetting. threads on and off very easily. the slim mount doesn't have any front threads, so it won't accept a lens cap. it does come with a plastic cap, but it doesn't fit tightly, would only be practical in a camera case, not for walking around.

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.

This filter works great, but, it is hard to get off. The ribbed part to hold on to is so small. If you tighten it very much you can hardly get it off. Also it does not have clicks or numbers and it will move on you easily.
You have to keep checking it that it has not turned without you knowing it. It works great but these other areas could easily be addressed. It was not cheap by any means. Are you listening B and W?

B+W is a brand with a reputation for quality. As I have started taking my photography more seriously I decided that I needed a few higher quality filters. The slim stature of this filter makes it great for wide angle shots where vignetting can be problematic. The only issue for me is that you can't stack another filter on top of this one because there is no threading, but all in all I rarely need to do something like that. I highly recommend this filter.

I had to return this filter, but only because I made the mistake and wanted a clear/skylight filter. Anything that B&W makes tends to be high quality. But, of course, you get what you pay for. I did use the filter for several shots in bright sunlight, and found it to be very effective against glare, if that's what you are looking for. I strongly recommend it.
