Kase Filters: KW Revolution Plus Magnetic Filter Review

Filters are an important part of my kit. I don't use them for every outing, but sometimes they really add value that can't be achieved in post processing. I've used CPLs to reduce reflections on wet rocks by waterfalls and reduce haze in the sky. I've used ND filters to help me get longer exposures when I otherwise was limited by the amount of ambient light.

So, when Kase sent me a set of filters I was curious to see how they would perform. Check out this video to see my review.

This set included an inlaid magnetic ring, a circular polarizer, and a UV filter. I took them out for some test shots to compare with and without the filter. The filters did a great job of adding pop to my images. They reduced haze, brought out blue in the sky, enhanced colors and added clarity.

I appreciated the ease of use of these filters. You simply install the inlaid magnetic ring, and then it’s super simple to pop a filter on and adjust it. I've always been a fan of magnetic filters for this reason. There is no concern with a filter getting stuck on your lens and not being able to remove it; this can happen with certain types of screw on filters.

Another nice feature of the Kase filters is the color coding on the outside rim. This makes it easy to differentiate your filters at glance as you pull them out of the case. My old set required more careful inspection, and this wasted a quite a bit of time. Every second matters when you're trying to shoot quickly, so I really appreciate this advantage of Kase's product.

Kase also has a wide range of sizes and types of filters in stock, which I find to be a big advantage over other magnetic filters I’ve owned. My filters are all 82 mm, sized for my wide angle lens. I use step up rings to use them on my other lenses. With my old set, I only had an ND 1000 neutral density filter. This was often times too dark for the amount of ambient light. I really wanted a mid range neutral density filter to address this, but I could not find anything other than ND 1000 for my old brand of magnetic filters. Kase has ND 8 and ND64 in 82 mm in stock, so I'm glad to finally have a solution to this problem. They also have specialty filters, like Black Mist and Solar filters, in the size I need.

And for the final test, Kase sent me two lenses to compare what happens when you drop a lens with a regular screw on filter versus their magnetic filter. This was definitely the most anxiety inducing part of the review; drop a lens?? The horror. But, the review must go on. I dropped the lenses side by side. The screw on filter breaks in place, and is really difficult to remove from the lens. The magnetic filter popped off during impact and remained intact. I don't plan on dropping any lenses in the future (but no one does, do they?), but if I do, it's good to know that I won't have to worry about the filters.

So, I am definitely a convert to Kase Filters. This was a welcome change from my old system. For me, it's the color coding and the availability of ND and specialty filters in the size I need.
