Making the best of the six month delay I figure I will put $10 or $20 in a jar each week and then when the upgrade comes out I'll get a 2.0 X III extender for my 500 and it will be almost "free."Well this is interesting! I do have a 2X but I miss a ... 500mm!
Then compare the 5D3 with 500 + 2.0 X (1000 mm) vs my 7D with the 500 + 1.4 X (1120 mm) and see which one wins.
How many days must I do the same ? (Yes, I can divide please don't answer!)
