Review on 📷 AutoFocus Lens Calibration Tool - Compatible with Most DSLR Cameras: Focus Pyramid by Leslie Matlak

I bought this to keep my Leica M rangefinders under control and I wanted to put together something more that I can trust - well, FAIL! The idea is not bad, but fails miserably due to the construction and partly the design because of the costs. First off, it's a glorified piece of paper that's not even laminated or protected, meaning it'll last about as long as a paper crane. Secondly, the labels aren't bold enough for POP and don't use the right typography to maximize the convenience of the optical viewfinder. Essentially, this means that despite the price claim, it should be MUCH better. Don't buy it! Only not!
