lololololol. . .nice!

Holy crap, I didn't know how wonderful the reviews are!

Are you required to buy the lens first before they're reviewed? I guess not. :D

By the way, why hasn't Moose Peterson gotten his hands on this lens yet? I'll bet you he'd love to stick a 2x teleconverter on this!

Both mounts show as "Only 1 left in stock--order soon (more on the way)". How much do you want to bet it's the same lens and they'll just put whatever mount you want on it.

Here's the nikon mount:

edit: Have you read the reviews on this? LOL! 'By the way Amazon, it's spelled "cannon", not "canon"...'
edit2: This one brought some tears of laughter. 'The Sigma 200-500 is simply amazing. Yes it's a little pricey, but if shooting long-range targets is your passion, this is the piece for you. Just last week I was using mine to shoot some deer out in a field. I was probably about 300 yards away from them. With the Sigma I was quickly and easily able to line up a nice shot. The detail on the image was amazing...so crisp and clear, so I could aim exactly where I needed with no fear of missing or blowing the shot. With that I pulled the trigger and took the shot. The deer dropped immediately. When I approached it I found my shot hit my mark exactly. The deer's neck was almost completely separated only attached to the body by a small thread of flesh. Getting this deer head and neck mounted to display in my den was so much easier than normal as the part I needed was already separated from the deer. This is simply the best piece of artillery I've ever used. I highly recommend.'

Too bad it's Canon mount though.

At least there's free shipping!
