The doorbell rang and the mail lady delivered the anxiously awaited package during lunch...my almost new[2 mo. old] 100-400L mk2. I got it from a hogger who decided it was not needed in her bag. I put it on the 5d3 to find out of the box it was pretty darn sharp, same thing on the 70d. A session with the Lens Align and some final tweaking on the outdoor power transformer target and it was about as perfect on both cameras as one could hope for. YES!! Actually, it seems to be only slightly better in the center than my 100-400 mk1 , but better in the corners...that seems to be the consensus of what I've read before. Main reason for purchase was the better IS...I'm a bit shakier than I used to be, and I can see the difference already. I'm totally happy with the pics it makes. See my trial posts in today's photo gallery .
Now I gotta sell off the MK 1 to keep Momma happy. It'll be listed in the classified in the next few days after I get some photos ready. John

Congratulations on your new lens. Have fun with it.

Thanks, I'm sure I will. It's not much different than my mk1 is, except better sharpness in the corners. I do love the better IS though, as I'm getting a bit shakier when shooting handheld. Lots of time a monopod is less than handy.

I was surprised to see that I can use it as a push/pull just like the mk1 if I choose...neat...and quicker too.

Other than the push/pull feature the biggest difference is the minimum focus distance. The Mk II cuts that distance in half of what the Mk I allows. That was my deal maker, and it paid off greatly. The lens works very well with both Canon T/C's. Have fun with it and enjoy your results!
