White-Breasted Nuthatch by No Small Wave, on Flickr
Canon 1DIV, Sigma 300-800mm f5.6 @5.6, ISO3200, 1/640
As a student working part time, I don't have much cash available to me to buy gear to do what I really want to do, which is take amazing photos of cool birds. As we all know, that gear is expensive. Obscenely, grotesquely expensive. Basically, you really need to be independently wealthy or a retired aerospace engineer or something to even think of taking up this hobby. Since I can't even come close to affording a 600 f4 IS II, I'd been looking at other options including used, non-IS Canon 600's and the Sigma 800mm prime or 300-800mm zoom, all while saving up what money I could.
While looking into the Sigma 800, I realized that there is very very little info out there. No one has really given it a comprehensive review and info and sample pics are scarce. There's one kinda crazy guy who wrote an entire online book about bird photography who wrote a page about it but that's about it. I'd pretty much figured on trying to save up for an old Canon lens and hope it didn't break ever.
So a couple months ago, by complete Craigslist serendipity, I got a stellar deal on a used Sigmonster. I just couldn't pass it up. It sat around for a while until this summer when my schedule finally allowed me a chance to do some bird photography. So here's what I've found out about it so far:
1) It is not a telescope. For some reason, I tried using it like it would somehow allow me to take sharp photos of sparrows 30m away. Not gonna happen. 800mm is not that much longer than the 600mm I was used to (300mm non-IS + 2x TC). Once I wrapped my head around that, things were much better.
2) AF is quick and generally very accurate. It's at least as accurate as my 300 at 2.8 and more accurate than the 300 with the TC. Its obviously not as fast as the bare 300, but it is quicker than the the 300 with 2x TC by a good margin. The AF is silent.
3) The lens is wicked sharp at 800mm. At first, I was disappointed with the sharpness because of point #1 but once I started using it correctly, the results were fantastic.
4) The lens is really contrasty. This is something I've noticed with other Sigma lenses, too. A lot more contrast than the Canon 300.
5) The lens is unbelievably heavy. I thought that wouldn't be a problem since I routinely hand hold my non-IS 300 2.8 and carry that around on a BR style over-the-shoulder strap, but holy crap the Sigma is a millstone. It is tripod only. I've taken some hand held shots, and its fine for a few, but there is no way this goes anywhere without a tripod and gimbal head (which I have, fortunately).
6) IT WILL NOT TAKE A TELECONVERTER. This is one thing I'm actually really bummed out about. I wanted an 800mm lens so that I could get 1120mm out of it. I have a 1D, it should (and does) focus at f8. Of course, a TC will physically fit and manually focus, but Sigma disabled AF with all TC's for this lens (I know because I checked with them). I bought a Kenko 1.4x specifically so that it would AF with my 1dIV, which it should do, and it doesn't. I taped off the contacts to trick it into autofocusing and it works but IQ is iffy. Its going to be a case of using it only when absolutely necessary to get the shot.
Here's a few more shots I've taken with the lens:

If anyone else has, or had, this lens and would like to share their thoughts, that would be great. If anyone has questions about it, I can try to answer them. I know at least one person here messaged me about it a while back.
