Hi . I have a problem I don't fully understand, at present . Mounted my 5D on a fairly sustantial tripod this morning to take some frosty foliage pictures. Lens a 24-105 'L', remote release . Exposures typically 1/3rd sec, f16/22 . Didn't lock mirror. Every picture on Lightroom magnification show movement, some a tiny amount, many quite a lot . ??? . :(

1/3rd of a sec will certainly show movement if there is any. Try mirror lock, 2sec delay or remote release - also was the IS turned off - might be trying to compensate for movement that isn't there?

Thanks Nigel . Yes forgot to turn IS off . Could well be the problem . Will check tomorrow .

I had the same thing when trying to shoot the Milky way, only to read afterwards you should always knock IS off when using a tripod as the motor actually creates movement in that situation.
