20 Most Recent Sigma Telephoto 400mm f/5.6 APO HSM Macro Autofocus Lens for SA Questions & Answers

Sigma makes their lenses with a variety of mounts. A lens with a Canon mount, for example, will not fit onto a Sony camera. Assuming you get the Sigma lens with a Sony mount then yes, it will be compatible with the Sony alpha.

Sorry, but it's not a DIY fix as the lens will need to be collimated. Without this, you'll just be guessing the correct position and alignment for the loose optical element and won't get your image quality back.

Professional repair and re-collimation will not be cheap though and the lens may not fully recover its former sharpness, so it may be time to let your faithful friend go.

I hope my answer has assisted you in choosing a course of action; please take a moment to rate my reply.

There are two versions of this lens.  The Telemacro version takes 77mm filters and is quite good.  It sells for $325-400 depending upon condition.  The other version "APO" is not very sharp and has low contrast.  It takes a 72mm filter and usually sells for approx. $125-$200.  I would not recommend this one for any serious photographer.  The Telemacro version is a nice affordable 400mm lens with decent performance.  Both lenses have slow AF, but the fast focusing alternatives are hundreds to thousands more.

Best you don't open it at all as you can damage the lens. Send back to manufacture

Tiffen is a brand of filters not a lens.
if your sigma lens will work on 1 camera and not on the other then check the lens mount, electronic contacts, clean them if needed.
check the settings in the camera if there needs to be a change.
