I'm having the same issue m36789 posted about!
I've already used 2 films and every time I changed the aperture, I could see through the lens the diaphragm going wider or smaller - I could see the image getting darker and brighter according to the aperture I was on. It was really amazing!!
Now, on my third film, I don't see the aperture changing like I used to, it's "stuck" in the wider aperture - and I have to imagine how it would look like when I choose a smaller aperture.
The battery is fine and the light meter is working, but I'm curious about how the camera suddenly changed the way it's showing the aperture settings.
Thanks a million!
Which body and lens are you using?
As mentioned above, ‘modern’ SLRs and lenses (as in, everything after the late-60 - early-70’s) were designed to keep the aperture fully open until the moment of exposure, when it is automatically closed (‘stopped-down’). This kept the viewfinder bright for composing and focussing.
The fact that your camera was stopping down during composition for the first two rolls suggests something is wrong. If you’re camera (or lens) has a depth of field preview function, this has probably been accidentally triggered. If it doesn’t, something in the mechanism might be getting sticky, requiring a service.
