Does Sigma 17-70 not compatible with Sony A57?

Recommended Posts

I'm thinking to upgrade my kit lens to Sigma 17-70 but I read some articles that Sigma 17-70 HSM is not compatible with Sony A57. I don't want to purchase USB dock and I'll buy from Amazon as used. Does anyone have information about this?

If it is like that. What do you recommend for zoom lens?

This is my experience with AF Sigmas. All my Sigma lenses from the film

era failed to agree with my digital Canons, no exceptions. FWIW, all my 

Canon, Tokina, and other film era EOS mount lenses work fine on digital 

Canons. Only Sigma's oldies [includes the Quantaray brand] fail to work. 

   

In contrast to the Canon situation, all my equally ancient film era Sigma 

[and Qantaray - built by Sigma] lenses in Nikon AF and Minolta Maxxum

AF mounts [all from the late1980s] are working fine on my digital Nikon 

and Sony cameras.  

   

IOW, if you were a Canon user, an old Sigma lens would be useless but 

Nikon and Sony digital cameras have worked with every ancient lens I've 

tried, I mean dozens of lenses ... all my own oldies and some oldies that 

I've borrowed but not owned. EOS firmware has a "poison pill" in it, but 

Nikon and Sony/Minolta firmware apparently does not.   

   

I would expect that lens to work fine, and especially if it has any return 

period, however brief, I'd not hesitate to buy it.

The old Sigma 17-70 is known to have AF issues on some A Mount cameras. That means it only works in manual focus. I don't know about the A57 specifically, but if users report issues, then this model is surely affected. For this reason the lens sells very cheaply, but it's still money down the drain if it doesn't work properly.
