One week ago I bought the Canon 50 mm f/1.2 for my new 5D Mark III, specifically for the very shallow DOF at f/1.2.
I am however disappointed with the sharpness of the lens at f/1.2. At f/2.8 its excellent.
I enclose two 100 % crops showing some text at f/1.2 and at f/2.8. The two images were taken at an angle of about 30 degrees, thus making the test independent of AFMA settings - it is clear that there is a focus shift, but that is not what I am complaining about.
I trust that you will agree that the f/1.2 image is a lot fuzzier than the f/2.8 image. My question to you experts is whether such a difference in sharpness is to be expected or if I should return my glas? Your help is highly appreciated
Took this shot of my daughter having her bath as an example of "Real World" results...(Canon 1Ds MK3, 50L @ f1.2 and 580EX II) Note the DoF is so bloody thin that even her nose and left eye are already OOF
All I've done to this picture was a bit of white balance correction and cropping to 100%
I don't think there is anything else that I could possibly ask this lens to do for me, You can count her eyelashes!!!... Everything else is just semantics and virtual blablabla
