Hi guys

First post after just getting my K10d, I am interested in wildlife and motorsport and would like a zoom lense. Having spent all my money on the camera I have a very limited budget. I have been looking at the following

Sigma 70-300 F4-5.6 DG Macro
Tamron AF 70-300 F4-5.6 DI LD Macro

Both can be bought for around £100, not sure if the Sigma is auto focus ( which I need ).
Does anyone have any personal info on either of the above or can recomend and alternative ?

Nice forum, might have to enter some of the photo comps. once I figure out what all the buttons do !!!!!!

My goodness, that was a fast response !!

Thanks for the welcolm

I have the Digital SLR User mag ( dec 2007 ), it has a small review on both lesnses the Tamron appears to get a slightly better review although both complain about soft images when at full 300mm. I was just wondering if anyone had thier own personal views.

Cheers
