About the B+W 49mm XS-Pro Kaesemann High Transmission Circular Polarizer MRC-Nano Filter

The B+W 49mm XS-Pro Kaesemann High Transmission Circular Polarizer is designed to reduce reflections and glare from non-metallic surfaces while enhancing color saturation and clearing atmospheric haze in landscape photography. This circular polarizer uses 99.5% light transmission Kaesemann foils cemented between precision-polished Schott glass elements, making it compatible with autofocus and auto-exposure functions on digital cameras. The filter features multiple anti-reflection coatings including B+W's MRC multi-resistant coating and an additional Nano coating layer that provides improved water beading for easier cleaning.

The thin brass rotating filter ring minimizes vignetting while maintaining durability, and the filter has a 2 to 2.8x filter factor that reduces exposure by 1 to 1.5 stops. The filter is most effective when used at approximately 90 degrees to the sun's position. It comes with a plastic storage case for protection during transport and storage.

Gearbridge - The place to go when you want to give your equipment a 2nd life

My transaction with Gearbridge turned out to an outstanding one. I had to sell my very much un-used gear and didn't want to get shorted on its value. I requested for quotes from a few sites and Gearbridge was on the higher end. I ended up with very pleasant conversations with Austin who followed up judiciously up to and including ensuring the payment went through. Moreover, he also bumped up the quote of one of my lenses as the value of the e-mount version was a bit higher. Overall, I would recommend Gearbridge highly as an honest establishment with Austin as a stand up individual to deal with. Highly recommended A++

GearBridge was most accomdating and helpful when I wanted to sell my old camera. The process was very simple and Austin was great.

Smooth, Professional Experience Every Time

GearBridge makes buying and selling camera gear easy and stress free. The process is fast, their team is responsive, and they offer fair prices whether you're looking to upgrade or offload equipment. I’ve had great experiences with both buying and selling, and it’s clear they really understand the needs of working photographers. Highly recommended.

Great experience - good prices and easy transactions

I had a great experience selling and buying. The amount I received was more than I was offered at other companies. Communication was great, the quote came in super quickly, and it was easy to ship my lens and receive money. I've also purchased a lens from GearBridge, which arrived super quickly and in great shape. Can recommend giving this company a go!

Good Experience

I'm 75 years old, so using this site and similar sites isn't terribly intuitive for me. But they got back to me in a timely fashion with every question I had. Once they received my equipment, they upgraded a couple of lenses and a camera body from "Excellent" to "Like New," which is what I thought might be the case, but since they weren't actually new, I did not want to claim. I got a notice when they received my package (for which they had sent me a prepaid label), and I got a notice when funds had been transferred to my bank account. If you are a younger person than I, you may want to select gear credit rather than payment. My conclusion is that these are folks that you can do business with, and it beats trying to unload stuff on PoshMark or other platforms!
