Learned friends,
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
