Me too.


Maybe I had a very good copy of the 55-250 and a poor 70-200 ... or expected too much difference. it was my first L and on a 50D.


To be clear, I didn't compared pixel to pixel but on the global result at 50% or 30%. I'm not a specialist and surely I missed some CA problems or else, but that's not the point for me.


And no, I don't have a doubt about 70-200 potential superiority. That's just my experience.
