I've been a photographer for years and a pro for some, but in all that time I've never come across a nicer filter presentation or polarizer. The filters come between two end caps, both precision machined from aluminum. There is no plastic here, nor any flaws or shortcuts in the machining process. I got these 49mm filters for a Leica. If ever there was an accessory kit that matches the feel and sense of this camera brand, this is it. I was, to put it bluntly, blown away.

While the UV filter seems to be every bit what I would expect from such a filter, which is mostly a lens protector with no image loss, I have no way to test such filters here. I can test the polarizer as this is a simple home test. It is very simple: take a picture of your monitor with the polarizer set to both minimum and maximum. Please look at the images that should be part of this evaluation to see the results.

Note that the test image shows the zones from 0 to 10. I set the camera to just clamp on 10 and run the 0 - 6 as you want to absolutely test this filter. The method is to see how many of the 8's, 9's and 10's are allowed through the filter at maximum polarization. Average filters, if the test is done correctly, will even show some leaks below 8. This filter completely filtered out not only the 8s and 9s, but also the 10s. I have never seen such a level of performance.

The pictures show the test pattern with the polarizer set to minimum (really zero), partially on, and fully on. You can see part of the monitor aperture fully because it is at a slightly different angle than the screen, so it is filtered out at a slightly different rotation angle.

It's one thing to create an excellent presentation, but it's another to have filters that work at a level that fits that presentation. These filters do. From now on, I'll shop this brand first when I need filters or photo accessories.
