I would give almost anything for a sharp, reliable 50mm lens like the 35 IS that I rented a few months ago.
I have used a Sigma classic 50mm 1.4 for the last few years and am really tired of the erratic autofocus. I rented a Sigma 50mm Art lens and had even worse problems with the autofocus.
A few weeks ago I bought a used 50mm 1.2 L. Guess what, I'm sending it to Canon tomorrow for an attempt at focus calibration.
Hello, what do you mean by focus calibration? Do you mean AFMA of 50mm 1.2L with your camera body?
I also got a used 50L with warranty for about a month now. Still I can not decide, if its a lens problem or user problem. I seem to shoot at F1.2 to F2.0 at the wrong scenery (portrait with lots of cluttered nearby things around) and it doesn't have the wow effect I am expecting. I use it on both 6D and 70D.
I bought Reikan Focal to AFMA. I couldn't nail AFMA value without this.
I don't know how to do further test, to test my lens. and thinking it might be user setting error.
When all the things are behind the subject, the subject look sharp at F1.2. Otherwise not so good.
If I got time and send it to canon? what should I tell them? Its better to be specific.
