I'm not privy to the UK/US conversion rates, but I do know that Sigma makes two variations of the 70-300 lens. The one that is more expensive is the one that gets good marks. A friend of mine asked me for advice on a lens to get for his fiance around Christmas. He ended up going with the lens in question. I did a quick test for him on my 5D to make sure it worked and it did. It proved to be a sharp lens for the money. Don't expect it to focus swiftly though. It was rather slow to rack from minimum to infinity.
That is actually one of the reasons you see so many wide angle shots for mountain biking. The depth of field is huge at smaller apertures. Even at f/11 a 70-300 lens would have very limited depth of field on the mid to longer end of the lens.
I have yet to shoot any mountain biking. hahaha But the trails that I have experience with around here prove that a 70-200 f/2.8 would be of limited utility in most areas of the trail. From some of the photos I've seen you guys post on these wide open hillsides, I could see how a telephoto would come in handy. All the local single track is heavily forested. With ticks and chiggers waiting to eat you if you step of the trail. LOL
I use the more expensive APO version, it seems good, but tbh, i dont have masses to compare it to. I have read contrasting reviews on whether or not the extra for the APO is worth it, some say definately, some say meh.
That said, i have only shot birds with it in the past, wouldn't really see much point for biking (for me).
I used to have that lens for Canon mount and it was superb, bar the lack of decent AF and the dust got right into it pretty easily!
The image quality was amazing and really very good. My 70-200 f/4L delivers great results and the Sigma wasn't far behind, though the colours aren't as bright. _________________ MTB-Addict Flickr

Are you referring to the lens i posted a link to or the APO version that sam_g is talking about? If it's the one i posted a link to i may well go for it.
