monsoonphoto.net Posted October 16, 2004 Share Posted October 16, 2004 I'm not sure what happened here. But on a shoot yesterday with my M6 TTL, I found that from mid-roll on, every single shot had a band going down the left side of the frame. The second roll produced the same problem as well. Is there something wrong with the shutter? Am I due for a dreaded CLA?<div></div> Link to comment Share on other sites More sharing options...

johnmarkpainter Posted October 16, 2004 Share Posted October 16, 2004 Alan, It is actually referred to as "Shutter Banding" and that is probably what is happening. jmp Link to comment Share on other sites More sharing options...

monsoonphoto.net Posted October 17, 2004 Author Share Posted October 17, 2004 The problem persisted in both flash and non-flash frames. Link to comment Share on other sites More sharing options...
Rob F. Posted October 17, 2004 Share Posted October 17, 2004 Relax, Alan. You say "CLA" like it's a bad thing. Yes, it's time. Link to comment Share on other sites More sharing options...
patrick_jelliffe Posted October 17, 2004 Share Posted October 17, 2004 It's (hopefully), just a tensioning adjustment--the two curtains are out of sync and one needs to be tightened up a bit. A CLA is probably in order, but if you don't have much mileage on your TTL, DAG would probably do the adjustment for a reasonable sum.

neil_parker Posted October 17, 2004 Share Posted October 17, 2004 If you hadn't said that it happened in non-flash frames I would be sure it was a flash sync problem. The color difference indicates flash exposure on the left, and ambient tungsten light on the right side. Also if you study the shadows in the second shot it become obvious that you have flash exposure on the left, ambient light exposure on the right. Are you sure you didn't have your shutter speed set wrong for flash? Link to comment Share on other sites More sharing options...
monsoonphoto.net Posted October 17, 2004 Author Share Posted October 17, 2004 Well, it was the first time I was using the flash, so that could be it. I set the shutter dial to the flash icon and fired away. Perhaps I should set a lower shutter speed? Link to comment Share on other sites More sharing options...
neil_parker Posted October 17, 2004 Share Posted October 17, 2004 If it is doing this set on the flash sync setting then you still may have a problem, seems like some testing is in order. I would try it with and without the flash, and try the flash on 1/30 & 1/60. Also you could fire the flash with the back and lens removed, pointing it at a white card or wall and see if the whole frame is illuminated.

monsoonphoto.net Posted October 18, 2004 Author Share Posted October 18, 2004 Thanks for the tip, Neil. Here's what I found: at 1/60, the flash doesn't even fire. At 1/30, only a portion of the frame is exposed. Strange. Appears to be a flash sync problem. Link to comment Share on other sites More sharing options...
