Sigma 70-300 lens - opinions

[GeorgeUK]

Hi all,

I wasn't actually planning to get one of these but it has been offered to me second hand (only used twice, mint condition) at a very attractive price.

Anyone had any experience of this lens. Any opinions? Worth a pop at £50-60? (I think it it just over £100 new).

PS This is not the APO version of the lens.
