Almost anyone that has used the older, first generation 70-200 siggy prefers it.
An unfortunate reality - Sigma praises the HSM model for being:

QuoteQuote:
improved in optical performance and retains close-up ability with a minimum focusing distance of 100cm/39.4in. SLD (Special Low Dispersion) and ELD (Extraordinary Low Dispersion) glass elements provide excellent correction for all types of aberrations. High image quality is assured throughout the entire zoom range
A claim far-fetched IMO.
I wished it were so, and I could get better images than I could above, but I just could not improve on them no matter how many times I tried...

If you have adjusted your sharpness setting stronger, could you put it to normal and try again?
As mentioned above, I'm shooting RAW - those in-camera settings don't apply.
In ACR, it's on the default setting for sharpness - which doesn't really matter anyway as images from my all my other lenses don't give me such soft results, particularly in the centre, at this same setting.

That looks about right to me, Ash. The softness I mentioned wide open includes a bit of haloing. Again, I haven't handled the Tamron or 50-135mm, but I'm still quite happy with this lens. Maybe it's just the benefit of not having anything firsthand to compare with...
I appreciate your input.

The Tamron 70-200 I had whilst having some haloing wide open at minimum focusing distance, corrected significantly at medium to long distances.

This is where I am surprised no one takes me up on my offer to buy lenses here and ship them over after i test them and send images ot the buyer. I'd need to charge a small fee for my time but i think it saves a lot of potential grief for the buyer from OZ.

I agree.
So do you have a good Sigma 70-200 to sell me?

The only f/2.8 sample I got from mine before the AF broke:

$799.

It's going back to B&H.
Simply cannot get the same results as deadwolfbones has above - that's an extraordinarily sharp shot wide open. Yours would have been a definite keeper.

What happened to the AF?
Did you get it repaired or did you return the lens?

The HSM died, as best I can tell.

It's been at the service location for 2 weeks. No word from Sigma yet.

Oh that's right.
I've asked you that more than once.
Sorry - lapsed mind, or is that lost mind... I dunno - night shift does strange things to the body...

No worries.

Just fired off an email to my contact at Sigma. Hopefully they'll let me know what's what.

From the picture info, it looks like it was taken at 70mm, not 200mm. From the reviews I have read the IQ is much better at 70mm than 200mm. The reviews I have read have also said that this lens is weak in the Macro range.

I would find some shots at 200mm F2.8 before exchanging this lens. (especially considering that you don't live next door to B&H).

One other thing is that B&H is rigid about the 15day return policy, so if you are going to return it vs. exchange it, keep this in mind.

yep, it's too bad you don't live in the states. B&H will cover shipping both ways for a defective lens which yours might be if it's halo'ing.

AFAIK, all 70-200 lenses will be a bit less sharp at the long end as was my Tamron 70-300.
I'll post some 2.8 crops when I get mine replaced in a week or so. I had to pay shipping back to A&R photo.
One other thing is the 102xxxx serial# lenses seem to have a bubbly front lens coat and flaky HSM motor. Not sure what your serial# was, but if it was 104xxxx, you should have one of the better ones...

Mine is also sharp at 2.8, more in the lower end but still quite acceptable in the 200mm range. Your results should be much better. I purchased mine 2 years ago when they first came out. It is a keeper so far. IQ is quite good. I am at work right now but will post a few photos to show both ends of the range tonight.

Just got the repair acknowledgment from Sigma. Looks like it was serviced under warranty ("replace HSM focusing roller; adjust AF data--checked all in good working condition") and on its way back to me.
