p.1 #1 · p.1 #1 · Older 'white' Sigma 300 f2.8 APO won't auto focus


A friend of mine has this lens on his Sony A65 body. It won't AF but when he puts on his 1.4x Sigma APO converter it will AF!!! The Sony A65 body has 8 pins, the Sigma 1.4x has 8 pins and the Sigma 300 F 2.8 has 5 pins. Whats going on?
Thanks.
Pat

Hi Pat,

A quick search turned up this...

Notice to Sony a77 and a65 owners using Sigma's Sony fitting lenses:
http://www.dyxum.com/lenses/sigma_advisory.asp

...where they refer one to this service notice from Sigma Global from 2011...

https://www.sigma-global.com/en/news/2011/10/14/996/

...where one will notice that this particular lens is not mentioned. And here from 2010...

...with this particular caveat, "* For lenses discontinued several years ago, a modification may not be available. For further details, please contact your nearest authorized Sigma Service Station." I'd suggest a call to Sigma and see if there's anything they can do for you with this particular lens. They are a great bunch of folks out there in Ronkonkoma, NY (they keep my fleet in top shape!), they'll give it to you straight.

Best of luck and keep us posted, I'm sure there are other folks looking at their vintage glass and wondering if it's still serviceable!

Thank you for contacting Sigma USA. If your lens is the DG version please send it in for a firmware update, if it is the older version it is beyond its service life and can no longer be updated.old version.
