bourne Posted August 9, 2022 Share #1 Posted August 9, 2022 Advertisement (gone after registration) When I set the the "max" shutter speed setting to 1/f4 with my 35mm summicron the camera still selects shutter speeds below 125th etc... Not sure why this is happening. Hope someone can clarify this for me. Probably "operator error"! Thank you. Link to post Share on other sites More sharing options...

M11 for me Posted August 9, 2022 Share #2 Posted August 9, 2022 ISO? On Auto? Link to post Share on other sites More sharing options...
hteasley Posted August 9, 2022 Share #3 Posted August 9, 2022 Are you using a 6-bit encoded lens, so the camera can detect the focal length? Link to post Share on other sites More sharing options...
bourne Posted August 9, 2022 Author Share #4 Posted August 9, 2022 Yes, using a 6 bit lens and ISO is on auto. Thank you. Link to post Share on other sites More sharing options...
Jeff S Posted August 9, 2022 Share #5 Posted August 9, 2022 In ‘good’ light, with ISO within you selected parameters? Jeff Link to post Share on other sites More sharing options...
lct Posted August 9, 2022 Share #6 Posted August 9, 2022 (edited) There was not enough available light within your selected auto iso parameters i suppose. Then the camera chose a slower shutter speed instead of a higher iso value as M cameras usually do. Example: 1/2f - 6400 iso as auto iso parameters with a 90mm lens. Trying to shoot in low light at f/8, the camera will choose 1/40s - 6400iso instead of 1/180s - 25,000iso more or less.

bourne Posted August 9, 2022 Author Share #9 Posted August 9, 2022 Yes Jeff, in good light it is within parameters. Thank you. Link to post Share on other sites More sharing options...

I was questioning whether you experienced the issue in good light and without exceeding set parameters. I suspected not, and was going to explain why, as you’ve now learned. Your options of course are to set different parameters, mind the light or accept the consequences. Jeff Link to post Share on other sites More sharing options...
rramesh Posted August 10, 2022 Share #11 Posted August 10, 2022 If speed is important for you, one way would be to create a user profile which you can select with the ISO Dial set to Manual. In Menu set M-ISO to Auto. This is will enable camera to pick any ISO up to the maximum of 50,000. In menu set Maximum Exposure Time to 1/2f. For a 90mm lens this will equate to 180sec. Save as a user profile. Now every time when you take a picture, the camera will compute the appropriate ISO for the speed you have selected within the camera ceiling ISO of 50,000. 2 Link to post Share on other sites More sharing options...
