Excerpt: The build is very solid. I have owned multiple B&W filters over the years and they have uniformly been well made. I am including two images. Both were shot last year off of a dock in Florida, not with this particular polarizer. I include them because they show the difference a polarizer can make.
Excerpt: Excellent quality at an affordable price. Polarizer are more useful than most people realize - the downside is the expense. I find this Kaesemann to be every bit as effective as polarizers at almost double the price.
Pros: Clear Optics, Consistent Effect, Easily Mounted, Strong Construction
Excerpt: This is my second circular polarizer and a huge upgrade over my first. I highly recommend this to anyone looking for a high-quality CP filter. Definitely cannot beat the quality of the glass or construction. B+W is definitely my go-to filter company from now on!
Excerpt: operates smoothly, very noticeable effect. this is one of those purchases you get under the excuse of "get the best so i don't have to upgrade later" and its completely justified. it has a heft to it, it doesn't bind or cross-thread. i'm using it on a 70-200mm f/4L IS and it never comes off.
Excerpt: High quality construction. Flawless glass. Bought a lot of junk before this. Don't be fooled by price. Lower prices usually means lower quality glass and that defeats your camera purchase no matter how good your camera is.
Pros: Clear Optics, Easily Mounted, Firm Mount, Strong Construction
Excerpt: The saying goes "the best things in life are free." Well sometimes the best things can be expensive, such as the three L lenses I have acquired over the past few years (and a couple of not cheap 3rd party ones as well.) I learned early on not to skimp with the glass on front, whether a clear UV haze, ND, or a CP. Your expensive lens is only as good as the filter letting in the image.
Pros: "post Card" Type Results, Clear Optics, Consistent Effect, Easily Mounted, Firm Mount, Strong Construction
