UPS delivered my 30D and 100-400 lens today. What a monster, at least compared to my Panasonic. I inserted the battery and CF card, turned it on, aimed it out the window, and wow, did it focus fast. I haven't actuated the shutter yet. I have a lot of reading to do. I do have one question. Of course it came with just one battery. Does it hurt to recharge the battery when it's still got a half a charge? I haven't checked the price of batteries, but I assume they're not cheap.
Canoga Camera were great to deal with. All they talked me into, along with the lens, was a UV filter. I used to always have sky filters on my lenses for my 35mm Nikons and I figured for the $$$$ I spent on this lens, it's cheap insurance. Also, the owner's wife called me a couple hours after the purchase to thank me and verify the address. I'll deal with them again.
