Pros: update
Cons:
update

Well, and my Sigma drives me mad. I discovered, that it blocks focus on infinity whenever it wants. The only way to unlock it is to turn it firmly clockwise, and just after that counter-clockwise. It really works. I will wait till my guarantee ends, then I will send it to a shop where I bought it. However, it is still good enought to take pictures with it. These are just some of them:

Pros: built like a tank, HSM motor, manual override, sharp from F2.8, it comes with a nice pouch, excellent hood, great tripod mount (I can take it off when I dont need it), front does not rotate when focusing, it doesnt change its size when zooming, minimal focus distance 1 meter, EX series - I love da million little shining things :)
Cons:
the damn front CAP!! 77 mm, for some people weight

I purchased this lens as my telezoom for sport shooting (in general quads) for (in recount) about $900. When the nice red and black box came to me, I was very happy. When you open it, a proper black pouch shows up. Certainly, in it you'll find a lense (and a strap to the pouch).

My first sensation was like "wow, what a great piece of lens!". It is really well built, and in its casing youll find a millions of little shiny things. I just love the effect!

In some minutes Ive made some shots of my dog. I was just amazed how good this lens is! Here
you have two examples: http://www.pbase.com/norbert06/image/80875822

AF works perfectly accurate and it's almost silent. It doesn't hunt in low light or so. Of course you can override it whenever you want.

The next day I went to a quadcross race. I took off my D70s and Sigma 70-200 and made some shots before the start. Everything is clear. I went to a start stretch, took off my camera again. they started. I had made some shots, then I started watching it. And what? First one was overexposed like I set +6 EV or so, and aparat of that one every pictures was horribly blurred! I started looking if I set everything as it had to be set. everything was ok. Than I looked at my lens. The Focus was locked on absolute infinity! I couldnt unlock it. Even when I half-pressed shutter, it was possible to hear, that HSM works. I couldnt unlock it also on manual focus. So I had to pack and come back. When I came back to home, and took out my lens.. it was fine! Everything was ok. I was so mad at it. I phoned to service and they said me they had not ever heard about similar accident........

Oh, and one more thing, I lost the front cap on the second race, it had to pop out when I was taking it off from my backpack. Shame that Sigma have't improved that thing.

At the second race, everything was just ok. Here are some samples:

Hope you like it.

Apart of the one accident and my lost front cap, I just love this lens Smile

Pros: Nice IQ when stopped down to f/8, cheap, light, well built (better than canon or nikon kit lens), comes with hood, metal mount, 58mm
Cons:
big CA, bad IQ when not stopped down to f/8, noisy and hunting AF

as I've written in cons, it has a really bad IQ when isn't stopped down.
Its build quality is quite well for the price, once it fell down mounted on my nikon D70s from 1.3 meter, nothing happened.
What can I say, that lens is quite good for the price. I would recommend it as the first lens for people, who are starting. It can show who you need, wide angle or telezoom, for a small price.
