Since I never use a TTL flash with my Bronica's, I'll give you my suggestion for a great solution. Using your TTL Metz flash, (make sure you've connected the TTL cord for Bronica ETRsi) take 8 shots at different apertures on A (Automatic), then take 8 shots at different apertures on M (Manual). I realize this will waste one 120 roll of film, but one negative will stand out as your perfect exposure. Yes, whenever you reduce the ISO in half, your basically overexposing the film by one f/stop. Just remember that this overexposes everything your shooting from foreground to background. With flash, this may cause your highlights to wash out, but any good lab could print for the highlights and make the background go darker. I used to shoot Vericolor at ISO 125 instead of it's rated ISO of 160.

SOURCE: Can't roll film for double exposure.

After taking the first shot, hold down the Multi-Exposure button while cocking the film-advance lever. This cocks the shutter without winding the film. You can continue to do this for as many exposures as you want. Just don't hold down the M-E button while cocking after the last exposure.

The Multi-Exposure button is the button on the front of the camera just below the shutter release button.

The lens does not have a shutter - that's in the camera body. The lens contains the aperture or f stop adjustment. It is done by injecting or retracting blades in the light stream of the lens barrel between the front and rear optics. Check the aperture blades to see if they move easily and open equally by varying the f-stop ring on the lens while looking through it. If not moving all the blades the same amount or it does not continue to restrict the opening as you increase the f-stop value, there's something wrong with the lens.

Are you sure you haven't accidentally activated any exposure compensation adjustment on the camera body?

My Mamiya RB67 triggers and shutter lease lever works but film advance lever doesn't move. Trigger button fired several times but film advance still showing 1.


This is not the best solution as it indicates a faulty film back. The film should advance without resorting to activating the film-wind release lever. That is only for intentionally advancing a partially exposed roll of film. Make sure the multi-exposure lever is not engaged and that the counter does advance and the red mark disappears as you advance to an unexposed frame.

Camera has a bad magnet, the A series were plagued by this.
Repairs will cost more than probably what it's worth.
The AE-1's used an electromagnet system to activate the shutter for a smoother press and less shake from the camera system.

I got lucky and recently purchased an AE-1 program that doesn't have this problem, it seems to be a hit and miss with these.

Shutter stays closed on bronica 645 etr medium format


Have the electronic shutter checked by a repair shop. Sounds like your Seiko electronic shutter has died or there's a short somewhere between shutter and lens. Hope this helps.

Mamiya RZ 67 lens is stuck on body


This is likely because the shutter has not been cocked all the way. Return the lens to the fully locked position and advance the film with the lever all the way down to reset the shutter. If it still doesn't work, move the lever to M for multiple exposure, make sure the back is aligned and trip the shutter release. Then fully **** the shutter again by pressing the advance lever down fully and again until it is reset. Then try to remove the lens again.

Film advance


In most film cameras, a battery is not necessary to manual advance film using the lever. Your Canon AV-1 is no exception. I have owned two cameras from the same group, the AE-1 and the Canon A-1. Neither required a battery for manual film advance.

Make sure the ring around the shutter release button is set to "A", otherwise the shutter won't release and the film lever won't work correctly. If the ring shows an "L", the shutter release is locked.

Here's a graphic of the batteries that can be used in your AV-1:

Loading film


After further investigation and because I can't keep my hands out of things I now know that the camera body is defective and that the shutter is jammed. It will only release with assistance. I was loading it correctly.
