Review on Canon EF 16-35mm f/2.8L ll USM Zoom Lens: Optimized Performance for Canon EF Cameras by Amar Amar ᠌

I bought it less than a month ago, but my puppy delight gradually turned into disappointment. There are very mixed feelings from using the lens. There are no complaints about the quality of workmanship. I am glad that nothing comes out and does not leave, if you hang the filter, then almost the entire lens will be protected. The color reproduction and contrast of the picture are simply excellent. The lens practically does not require the use of a polarizer, the sky turns out to be deep and saturated even without it. Now to disappointment. At focal lengths of 28-35 with apertures from 2.8 up to 8, it has a loss of sharpness at the edges and this is on crop, I can’t imagine what will happen on the FF (for which I bought a lens with a backlog on the FF). A very unfortunate discovery. I understand that you can live with this, but for the money that they ask for a lens and how the L line is positioned, this is an unacceptable quality. On my 40D it has back focus (in about 30% of frames). I hope to fix the problem with another carcass. Adjustment in our hole is impossible, alas.
