The DOF in your pic would hide most of the corner softness that bugged me.
So in other words it is "horses for courses". This lens will suit certain peoples photography style.

I am not bothered by corner sharpness as I generally *try* to get a smaller DoF in most my shots and introduce bokeh. It's just my style.

Plus I try to shoot to a composition and generally the most important part of the photo is somewhere near the thirds intersection anyway.

Bottom line: If you take photos where corner sharpness is important, then don't go for the Sigma, otherwise it looks good and has the HSM which I'd definitely prefer over the screw drive.

I just picked up a Sigma 70-200 DG II HSM.

Very quiet HSM, fast. Took a few photos and I am happy so far.

I will test more in the next few days and if time permits, post some results. I have 7 days to change my mine. So far the lens appears well build, smooth range and focusing.

Can hear this thing at all. Itl goes quietly to focus from close to infinity very fast.

For the price, I doubt it will perfect but should do the job well.

Yes, for the types of pictures I want to use a 70-200 for, the more uniform softness/sharpness depending on the range and f-number is probably a better fit for my post processing habits. Not to mention the better controlled CA of the tamron over most of the range. That is assuming the dpreview sample wasn't a bad copy and had something wrong with it. Other samples showed some increased CA, but not as bad as theirs.

I think their galleries are more telling of actual use, and they both are capable of producing nice output.

By this lens, do you mean the tamron or the sigma? Since this thread sort of went sideways into comparison, you should be specific.

Tamron 70-200 was the one that was reviewed. The main thing was autofocus performance and the tripod collar was baddly positioned.

Was the review about the pentax mount or not ?
If not, autofocus issues should not be addressed.

TAMRON 70-200mm f/2.8

TAMRON 70-200mm f/2.8

--------------------------------------------------------------------------------

I have the K100D and have been anticipating this lens. Today I saw a review that mentioned problems w/ autofocus using the K100D and the Tamron together. Is this a common problem or a single case?

Thanks.

I have the Tamron 70-200mm f2.8. IQ is almost as good as my f*300mm. It focuses about the same and both have the push pull af/mf 'sleeve' type ring. both are a bit noisy with the screw drive. I bought it for its IQ and have not been disappointed. As for the tripod mount, i've used both monopod and tripod with no problems. If I were shooting in crowds/weddings, I'd opt for the sigma as it is whisper quiet. If you have a local shop, try them both and buy what you like. If not, buy from a reputable store with a good return policy. Any lens can have problems, and Tamrons warranty is hard to beat.

you are right not even with Pentax, but optic quality is the same.I dont think that Tamron will change the optics of the same model. Thus I wanted you to see how sharp is that lens.

Since I made you angry Im so so sorry. I wont do that again.
