A Quick Question on Film Cameras
Jan 21, 2018 10:18:34 #
I just came across a Nikon N-90 (I think.) Can I change lenses on this camera without exposing the film? OR ... Will changing lenses mid-roll expose the whole thing?
Thanks
Thanks

Like on all film SLRs, the mirror blocks the light path to the film plane, so you can change lenses without exposing the film.

Not to mention the closed shutter.

Mark, Yes without any problems. Camera is designed not to expose the film when you change lenses.

Yes it is the closed shutter that blocks the light to the film, not the mirror. The N-90 is a Nikon
(1992-2001) film 35mm camera. It is no longer in production. My film photo class used some of these and the badged Nikon F90s last year for our university students' use.

Now it's interesting that I think in the manual they never mention that you can change lenses with the camera loaded. So in the case of the OP and if he read the manual from beginning to end do you think he would figure that out?

If changing lenses exposed the film, I'm sure the manual would say that. It probably didn't occur to them that someone would ask that question.

As the N90 does not have mirror lockup, there's not much danger there. Not sure, but I don't believe the camera allows the lens to be removed during an exposure.

you can trip the shutter with the lens removed, but that would only expose one frame of the roll of film.

I’m trying to understand how this is different than having the lens cap off.

The shutter is blocking any light from reaching the film. Even with the lens removed.
