Originally posted by Rondec No, I think you can shut it off for exposures less than 30 seconds on the K20 after a firmware up date.
Are you sure? I own a K20D and would REALLY be interested in that firmware update. I hadn't heard of it though...
You'd have to search for the thread but someone thought of a nice work-around for the K7 DFS issue. It can be turned off for exposures 30 sec. or less (not for Bulb mode), so the person used the multiple exposure feature to stack a bunch of 30-sec. exposures into one long exposure, thus bypassing the need for DFS. If the K7 is like my K20D then you can stack up to 9 such exposures into one.
I can't attempt anything even close to this, there is just no option of shutting of DFS on the K20D, whether for 3 seconds or 30- the option is to have it on all the time, or "let the camera decide based on conditions", which is basically no difference, I don't even know why they included such an option in the custom menu.
