So, I had my 5D2 since last August.. Over the time I have had it, I had more "Misses" then Keepers.. I always thought it was due to my shooting Crop bodies all this time.. So fast forward a little.. The last Party I shot, my cam started to do ODD things.. ( Random sensor cleaning, freezing up, along with the Shi**y Battery life I have always complained about)..
So I sent it in to Canon..
Its night and Day now... Took Kids to the Zoo yesterday and I am blown away! Only 2 or 3 Non-Keepers... The AF was spot on for 99% of the shots I took!!! And.. Over 300 Shots taken (All Raw, Tamron 70-300 with VC on, kids constantly asking to see the shots I took via LCD) my battery is currently sitting at 89% where it would have been at less then 40%..
