Just a quick thing, I've been using a 550D, or a Rebel T2I before this and had recently changed to a 6D. I used my 50mm F1.8 with my 550D before, it was a great moment, giving me bokeh which I've never seen before and amount of light which is so desirable in an APS-C, but after a while I realized that it was not really sharp overall and... it just doesn't click. It doesn't give the amount of details one would command in order to produce a good image overall. However, after leaving it aside for some time, I picked it up again and put it on my 6D, and it feels like a whole new lens again (Doesn't refer to the brand new idea, more of a change, something drastically different)! It's sharp throughout the subject that I wanted, gives me great bokeh and it looks a lot sharper than before. It just feels different. Has anyone felt this, something like breathing in new life into an old lens by using a new camera body?
