The on / off is not an issue for me since i have never turned it off. The auto off feature works great and I don't see any side effects of using it.
Play (bad, but you could set the review time to 8 secs and just deal with it)
Trash - Never use it, I edit after the shoot
Af/WB -That might hurt, I guess I'll have to shoot raw
Info, Jump & Magnify lol, HAVE YOU EVER USED ONE OF THEM? LOL
What we don't know is what new features that we will not beable to use. I don't plan on upgrading if I need a new housing. My only issue is the focus, I can live with it.
