Akaky Posted May 15, 2023 Share Posted May 15, 2023 I know that this is going to sound incredibly stupid, but I can't figure out how to zone focus on this lens. I've been zone focusing on Canon lenses for twenty years without a problem and now, all of a sudden, I've got problems. I got a Nikon FM2N and the fifty as a present last year and I want to use it, but it's going right by me. Are the colors of the numbers significant or am I just being incredibly obtuse here? I know the answer is going to be very simple, but I am still not getting it. Any help will be appreciated. Thanks. Link to comment Share on other sites More sharing options...
mike_halliwell Posted May 15, 2023 Share Posted May 15, 2023 (edited) Errr, what actually goes wrong? ..and don't just say they're out-of-focus....🤣 Edited May 15, 2023 by mike_halliwell Link to comment Share on other sites More sharing options...
Ken Katz Posted May 15, 2023 Share Posted May 15, 2023 Don't have this lens but if it looks like the one on the top of this page: https://www.kenrockwell.com/nikon/50mm-f18-ais-pancake.htm#id then the yellow lines on the silver ring refers to f11, and the blue and orange lines refers to f16 and f22 respectively. So if you set the focus ring so that the zone you want to focus at is within one of those colored lines pairs, and you set the aperture accordingly, then that is zone focus. They probably didn't include any indication for wider apertures since the amount of DOF available using a 50mm lens on a FF camera is so limited that it is not very useful for zone focus or hyperfocal distance focus.

It's that I've used Canon FD lenses for years and I know how to read them. This Nikkor was a bit of a Rosicrucian mystery and I couldn't find anything on the Net that spelled it out for me. Thanks for answering. Link to comment Share on other sites More sharing options...

SCL Posted May 15, 2023 Share Posted May 15, 2023 And the little barely visible red dot is for infrared focusing. Link to comment Share on other sites More sharing options...
BeBu Lamar Posted May 15, 2023 Share Posted May 15, 2023 (edited) How do you do it with the Canon lens? Besides why do you need to do zone focusing? You want to shoot very fast without having to focus? Edited May 15, 2023 by BeBu Lamar Link to comment Share on other sites More sharing options...
hjoseph7 Posted May 16, 2023 Share Posted May 16, 2023 (edited) It could be something faulty with the focusing screen inside your camera. Check to see if it's loose, or installed incorrectly. I have both versions of this lens and have no problems with either. Edited May 16, 2023 by hjoseph7 Link to comment Share on other sites More sharing options...
BeBu Lamar Posted May 16, 2023 Share Posted May 16, 2023 If you do zone focusing then the chances are you never have a picturs in sharp focus. They may be OK focus but not tack sharp. Link to comment Share on other sites More sharing options...
