I bought one about 2 years ago, also witht the battery grip. I wouldn't use autofocus for landscapes but i do use it for people shots and a couple weddings. It searches quite a bit. It sucks compared to the eos-1N i got recently from the big auction site. The other reason why i'm disapointed is that the camera shuts down in cold weather. Anything below 35deg. F and it won't work. I don't know if they all do this or not. I tried both battery options and no luck.
You've got to get the f5 if you want all the good features like 100% viewfinder coverage, autofocus, weather seals, metal body, mirror lock-up, and fast frame rate. just my 2cents
