I have heard and seen in some charts that the 1.8 is notably sharper at certain apertures than the 1.2. That said, with the possession of a 1.2L, I imagine there are many situations in which I'd rather shoot a picture with the 1.8 because of the sharpness. If this is true, then I see can only see myself using the 1.2L in rare conditions. Am I correct in my thinking? Or does the 1.2L provide better overall image quality than the 1.8 in almost all situations?
Which of the two lenses should I sell?
1.8 II
especially if you crop a lot.
