Bobby Posted March 4, 2022 Share #1 Â Posted March 4, 2022 Advertisement (gone after registration) I do a lot of long exposure and I typically use a rubber around the lens to sort of lock the focusing ring. But many M lenses have a focusing tab so I'm not sure it will work. are there alternative solutions? Link to post Share on other sites More sharing options...

a.noctilux Posted March 4, 2022 Share #2  Posted March 4, 2022 Depending on the lens, there is a small "non-tabbed" section on the focus ring. Heavy duty adhesive band may be put there to lock the focus ring. 👇 Or use old lenses with infinity lock ? Link to post Share on other sites More sharing options...

I’ve done long(ish) exposures but never even thought of the focus going off during exposure. 1 Link to post Share on other sites More sharing options...
