Ever wondered how some pictures get that really dark blue sky in them? It's really as easy screwing on a MRC Polarizer filter, and while you're at it you might as well use the B+W.

Polarizer filters increase the saturation as seen by the camera which helps to make the deep colors you see in photo books. Additionally, a Polarizer filter will remove haze from outdoor shots making them sharper AND will cut reflection from water, windows, and foliage - something you can't do yourself afterwards with Photoshop.

Keep in mind that using a filter like this will decrease your light by two stops and that you have to rotate the filter every time you move to ensure you're getting the right effect. Also, you have to use a filter like this only under the right conditions. Most of the time you won't need it but when you do it will make your picture A LOT better.

Since you're attaching a filter to the end of your lens you're introducing the possibility of degrading the final image. While you can use a B+W (or a Heliopan) filter with any lens BEWARE of using the cheap filters you find at your local camera store. If you're taking pictures that are important to you it is absolutely worth the extra money to get a good filter for your lens.

I've owned 5 different B+W MRC filters and all have been excellent. This filter is no exception. The polarizing capacity is very strong with this filter and it does an excellent job of reducing glare, reducing blue polarized light in the sky, reducing reflection, etc. Build quality is very high and the level of rotating friction feels just right.

The MRC designation is your cue that this filter will not produce ghost images when used on digital SLRs due to an anti-reflectivity coating put on both surfaces of the glass. Hence the large increase in price when the MRC designation is present.

Great quality in B+W and no complaints with this filter. It is lubricated so you can turn it and the oil made it onto on of my cleaning cloths. I guess this would happen with any circ. polarizer. Slight vingetting on wide angle (10mm-17mm) lenses. Get the slim one if it will bother you.

The polarizing offered by this polarizer is excellent... 5 stars. What has not been five stars is that this polarizer likes to bind up and get stuck on my lenses (brand new canon L's).... and believe me i put in on VERY lose. This might not be that much of a problem except of the front part of the polarizer spins (it is supposed to).. and the part your supposed to grip to take it off is literally about 2-3 mm wide.

costs to much for this problem...

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 of these, and I love them. 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! 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!
