I don't have any new numerical data to add to the discussion for sharpness etc, but I will say that after checking one out at my local camera shop this afternoon (I was a little stunned that they still had one as they only got one copy and no one had jumped on it yet), the "user experience" is absolutely fantastic. I admit that I haven't shot with the mk1 version of this zoom but the new version is lightning fast while focusing (and that's on a 5d mark II, the shop didn't have a 5dIII out for me to try with). The balance and feel are both wonderful and I ended up across the street scouring through Lightroom on my laptop to see what % of pictures i've taken with my 24-105 f/4L that were at a low enough shutter speed that they would have benefited enough from the IS to make a real difference. I've been wishing I had a bigger aperture on the 24-105 for a while and I think I'm probably going to pull the trigger on this one and sacrifice the extra reach on the zoom for the bigger aperture and what most data point to be a sharper lens.
- I haven't shot at 70mm on a non IS lens before, can anyone provide any feedback on how slow they liked shooting on the mk1 version of this lens?
- When Canon has released lenses that have technical flaws or faults that they eventually fix, how long after the release are these typically discovered? In other words, how much of a danger is there in being a first mover here? I know we don't know until we know, but there are a lot of smart people on this forum with far more experience than me, so I'm always looking to learn off you guys.
