mholtsberg Posted August 4, 2011 Share #1 Posted August 4, 2011 Advertisement (gone after registration) Please explain when to use lens dependent ISO setting. This is a bit confusing and I cannot find any clear explanation.. Thanks in advance.. Link to post Share on other sites More sharing options...

ho_co Posted August 4, 2011 Share #2 Posted August 4, 2011 There's a rule of thumb that most people can hand-hold a 35mm camera at a speed equal to the reciprocal of the focal length. That is, with a 50mm lens, the slowest a person should try to hand-hold is 1/60 sec; with a 24mm lens, the slowest a person should try to hand-hold is 1/30 sec; etc. (The figures would theoretically be 1/50 sec for a 50, 1/24 sec for a 24; but you can't set those speeds on modern cameras, so take the next fastest speed.) Lens-dependent ISO setting means that the slowest shutter speed the camera will set will be the speed determined by the focal length of the lens, using that rule of thumb. That is, the camera will keep the lowest ISO possible until it would need to go slower than the rule of thumb and the lens in use dictate; when that happens, the camera will use that lowest speed and begin increasing ISO instead of dropping shutter speed further. I hope that helps. Link to post Share on other sites More sharing options...
Holybasil Posted August 4, 2011 Share #3 Posted August 4, 2011 You should also note that the rule is "designed" if you will, for SLRs. So it becomes redundant with an M since it has no mirror causing camera shake. Link to post Share on other sites More sharing options...
mholtsberg Posted August 4, 2011 Author Share #4 Posted August 4, 2011 Thank you, that does help. One more question please. Will that setting work on all lenses for the M8, or only the ones with "coding"? Link to post Share on other sites More sharing options...
lct Posted August 4, 2011 Share #5 Posted August 4, 2011 Thank you, that does help. One more question please. Will that setting work on all lenses for the M8, or only the ones with "coding"? Needs coding to work as intended. W/o coding, the shutter speeds will just blink in A mode below 1/30s. Link to post Share on other sites More sharing options...
