I'm considering buying a used Sigma 50-500mm APO EX., and need to decide quickly. Sigma claims this lens won't focus properly on a65 and a77 without an update. Does anyone know if this is also true with the a77 II (or for that matter, any other SLT's than the two specified in Sigma's original announcement)?


When the A77 was released in 2011 an AF problem was discovered in several current Sigma lenses (original Sigma notice). I just got my A77, still had my A550 DSLR, and was looking to buy the Sigma 150-500. I waited on the 150-500 while this was straightened out.

This problem actually goes back to 2010 and the A55. All subsequent Sigma lenses work fine with SLT's.
