ownership:I own this lens
compared to:I don't have any other lenses with this sort of focal length range, so won't compare it in detail, but my impression is that it's about as good as the second, lightweight Minolta 35-105 introduced in 1988 ie a lot less good than the original heavy one.
price paid:effectively free
positive:Sharper than expected between about 24 and 125mm, although still benefits from. a stop of stopping down. Very compact for its focal length range.
negative:Mine is weakest at 18mm, where it needs F8 for good sharpness, and has that favourite Sigma defect of obvious decentering, which clears up by about 35mm. Linear distortion is a bit high and cannot be corrected in-camera.
comment:Good enough that I'd like to try one that wasn't decentered - if I could find one.
