extension tube for mamiya m645

[pixmedic]

came in today from KEH! extension tube for the 80mm f/4 macro lens on my mamiya m645 1000s.
(thanks to Derrel for posting a link to it)
being VERY new to film cameras, i do have a question. I already have a roll of film in the camera, but if I want to change lenses, or put the extension tube on, can I just lock the mirror up and take the lens off without exposing the film inside? I would love to get a few shots with and without the extension tube.

Long as you got the darkslide in you got no worries.

 

[pixmedic]

unlike the hasselblad bodies, the mamiya doesn't have a darkslide.

 

[JAC526]

Well damn. I had a RB67 which did have a darkslide.

Hmmmmm. So it doesn't have swappable backs? That kinda sucks.

 

[JAC526]

PM compur. I bet that guy knows.

indeed. no swappable backs on this one. hence my conundrum. certainly film users had a way to swap lenses in between shots. I cant imagine other film cameras completely sticking you with only ONE lens per roll of film.

Well like I said with the RB you just put the darkslide in and go for it. I'm assuming the 645s are all leaf shutters right?

focal plane shutter. the made a few lenses though that had a leaf shutter.

Why not take it in a bathroom, with all the pieces, block off all light around the door, and change it out?

I was developing film in the bathroom at night. Can't see why you can't do this there...

Just saying

 

[JAC526]

Ohh then you are good. Even with mirror lockup the focal plane shutter will block the film. I had assumed they were all leaf and if you took the lens off the shutter went with it.

Right?

because i MIGHT want to change lenses when im outside. at the park, by the lake...where it isnt very convenient to go find a bathroom to change lenses.

Just saying.

Right?

if i had the 70mm lens with the leaf shutter then yes, that is probably true. I THINK though, with the focal plane shutter i am ok with the mirror locked up. was just looking for conformation before i tried it and ruined a few frames.

I have a 645 pro and you can take the lens off at any time. Why wouldnt you be able to with the 1000s? Light comes through the lens anyway.

 

[compur]

Yes, you can change lenses on the 1000s without exposing the film.

Good heavens, I'm glad compur showed up! I was reading along and getting concerned. No worries, you can swap out lenses with film in the camera, I do it all the time and keep shooting! If I'm stuffing everything back into the bag and just carrying the body, I put the body cap on over the lens for safety's sake. No worries for light leaks, though.
