I seriously doubt it, since this was shot "on the run" and hand held. I was using auto focus since it was a moving object, so don't really have a feel for the magnification. I feel that it is slightly oversharpened and a bit contrasty.
Sorry I can't provide you with an answer.
It IS slow, typically. But since I knew pretty much the distances I would be working, having the lens set to LIMIT made for a pretty decent setup. The bees were working the azalea bush pretty heavy, so focusing was quite short. Of course, luck had a lot to do with it, as is the case for MOST of my photos . P.S. also note that I was using AF-C and this helped a lot.
