Upload & Sell: Off
I returned a 70-200 f/2.8 MK II because it was defective. Then decided to try the f/4 instead. Just got it. It works as it should, but falls short just a bit in IQ, focus speed, stabilization, and, of course, it is one stop slower. Decided I didn't care about the weight difference, and those accumulated small advantages add up, and can justify the price for the MK II. I am going to reorder the MK II and hope I get a good one. Probably going to sell my beloved 135 f/2.0 to pay the difference.
