SIGMA 70-300mm f/4-5.6 DL Macro Super II. Does somebody have one??

Hi Manfred the following may explain why we have had different experiences with Sigma.

Auto-Focusing Issue Affects Limited Number of Sigma Telezoom Lenses

June 16, 2010


After thorough investigation, we have ascertained that some APO 50-500mm F4.5-6.3 DG OS HSM, APO 120-400mm F4.5-5.6 DG OS HSM and APO 150-500mm F5-6.3 DG OS HSM lenses produced recently, may have a potential autofocus defect.
This issue could possibly occur in some lenses within the following range of serial numbers.
List of Lenses Requiring Modification:

• APO 50-500mm F4.5-6.3 DG OS HSM- Serial Number between 10633051 and 10972000
• APO 120-400mm F4.5-5.6 DG OS HSM- Serial Number between 10574001 and 10972000
• APO 150-500mm F5-6.3 DG OS HSM- Serial Number between 10674301 and 10972000

This is a limited problem that will not occur in any lenses other than those specifically listed above.

You guys make me worry. I was considering buying a 70-300 DG Macro for around $200.00. This is really cheap for a 70-300.
But if it is going to cause problems - not worth it.
Is it really that bad?????? :confused:

Andre it is probably fine, but the APO version is worth the extra $60-90 and I think the big problem was with the longer lens as shown above. I am a little hesitant to comment other than I have been pleased with my Sigma lenses and when searching the internet I came across much more positive comment than negative. There was a lens from another manufacturer that was criticised soundly (I can remember the manufacturer but not which lens) Just go online and do a bit of research and I think you will be reassured or maybe put of buying any lens from any one. Like most products if you want absolute reliability you need a very big wallet.
