My Sigma 10-20mm f/4-5.6 is softer at the top of the frame than the bottom, even when stopped down to small apertures, so I would like to have it checked out while still under warranty. It looks like there are four Sigma service centers in the USA:
Sigma Corporation of America, Ronkonkoma, NY C.R.I.S., Chandler, AZ Camera Repair Japan, Duluth, GA Bigston Corporation, Elk Grove Village, IL Does anyone have experience with these shops, that might steer me toward or away from any of them? I know C.R.I.S. was until recently the Pentax warranty repair center, and it seemed like I generally heard good things about them. -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
