Originally posted by stuskier Hello, I'm requesting your help selecting a special lens for my K-7. I shoot time lapse jpg's (hundreds or thousands sequentially) and stitch them together to form a video. All my shooting is fully manual - aperture, shutter speed, focus, white balance, etc. A common problem with time lapse videos (including mine) is flicker resulting from minute differences in the aperture size from frame to frame, because the mechanical iris does not return to the EXACT f-stop from shot to shot, even though the camera's settings have stayed the same.
Even if the aperture remains strictly constant,
and you don't change the nominal camera settings,
is the K-7's shutter sufficiently consistent to avoid flicker?
