Info on a Sigma UC Zoom 28-70 mm f2.8-4

Does anyone have any info on this lens? I saw that "Just me" asked about it last November but there was no info ... I picked up a used copy on a whim, but having mixed results with it. There's almost zero info on the web that I have found ... any help?!

This isn't a troubleshooting question; moved to the lens forum.

Is this the lens you're referring to: Sigma 28-70mm F2.8-4.0 Lens Reviews - Pentax Third-Party Lens Review Database ?

Or this one: Used Sigma Zoom Wide Angle-Tele 28-70mm f/3.5-4.5 Manual Focus ?

There are a few others in the lens database, so definitely check that out as well!

I did use one of these some time ago - a very versatile lens - though could be more useful if it were 2.8 all thru.

Photos of Sigma UC Zoom ...

Bonjour Adam,

Thanks for your message, and yes, this should have been a "lens forum" question ... sorry.

Attached are photos, and as "Just Me" previously stated, this lens has a 55mm diameter (not 58mm as the lens that is already in the Sigma review section) and its marked "Sigma UC Zoom" ... (UC = "ulta-compact" ? ... or "ultra-crappy", as I have read elsewhere). Again any help is greatly appreciated and as the French say, "Merci d'avance"! John de Poitiers
