Hi,
Just received a 60mm CB from a seller on eBay. I tested it today with my 501CM and it's giving me some strange problems. At some shutter speeds it fires completely fine but on others, the shutter will fire off a half a second later after I've pressed the release. For some speeds, it'll fire the shutter first, then lift the mirror and lock it up, open the curtains, lower the mirror, and close the curtains all separate 5+ second intervals. I've never seen this problem happen with other lenses so I'm wondering if this a problem with the lens. The seller doesn't accept returns but I've opened a request since I'm almost certain that the lens is defective. Can anyone chime in on this?
