this guy didn't want his picture taken
Since we're beyond karma and "my gear is better" I hope we can discuss this in cool blood :-) ... so: For this image size, I think the sharpness of the best zone (the hairs) is like than my 70-300L = 480mm without tc. But it's hard to say due to motion blur because 1/500s is the absolute minimum for 420mm, I try to have at least 1/1000 for shots of this kind - for this reason and if I'd have shot this one I'd have scrapped it for bad iq.
Which makes me want to point out again: A very good or even the best tc at lest at decent iso seems to be an aps-c sensor, and even if I ever upgrade to ff I'm likely to keep my crop camera for tele shots.
yeah i hear ya but to clarify a bit
its a crop, not resized.
I didnt scrap it because its still a funny shot
I was shooting mainly with the 600 on a gimbal and the 1D
i just had the 5D2 and the 300+tc on a strap at my side to grab periferal stuff like this
i should have had a higher shutter speed you are absolutely correct
I wish they would release a new version of this lens with the new hybrid 4 stop IS
you can notice the older IS is quite slow and clunky
it's compact size and weight make it awesome and I love the built in lens hood.
