Medium format cameras with electronic shutters ... aside from the RF645?

 
Koni Omegas are for wimps! Get a Mamiya Universal or Super Press 23. 😀 😀

Actually, I have no idea about any differences in weight. The Mamiya Super Press 23 I have isn't a featherweight, but it is managable. And it is for sure a system camera with excellent lenses. But I thought you got the Pentax because you wanted SLR. For exactness with the Super Press, you need a ground glass back. Even so, I never had a problem getting what I wanted with the viewfinder. It is just that for critical work and macro, the GG would be needed.

If I could get the Pentax to re-cock it's shutter without that slight movement of the film it would be nice ... not quite sure why it does that! It's only a fraction of a milllimeter but it's enough to ruin the shot.

I coud use the Hassy but that involves making the exposure, refit the dark slide, remove the back, re-cock the shutter then reverse the procedure for the next exposure ... ho hum! 🙄

The Bronica RF645 is absolutely perfect but it's 6x4.5 ... which is still a lot better than 35mm admitedly!

I thought someone who has had one for a while might jump in and say if that is a problem with all, or if yours is just out of whack a bit and might need a service.

There was a time when I lusted for the Pentax 67 also, but ended up with the Super Press 23. I have never really regretted it. They are good cameras and quite versatile. They also have 6x9 backs. I never thought that much about it as I can acheive that with cut film. But after getting the Zeiss Ikon 6x9 folder, I like that format better than I thought I would. And I like it better in roll film that in cut film. Go figure.

The camera should be OK as it had only had a few rolls of film throught it before I got it ... more a symptom of the design I would think!

I might sacrifice a roll of film and go through the process with the back open to see if the film is actually moving!

The Crown would be perfect I guess so options aren't a problem!

Simon,

I was checking the specs of the Mamiya 7 and under the section that describes multi exposures it says you still have to use the advance lever to re-cock the shutter after disengaing the transport mechanism via a sliding lever on the back of the camera ... so you're still having to apply force to the camera in some form!

The Mamiya 7 is an odd camera, Keith. The shutter is actually electronic so the advance lever doesn't physically cock the shutter at all. But if you don't advance the lever (even with multi exposure switch selected) the shutter won't fire. The multi exposure switch completely disengages the film advance, so while you need to apply force to *cock* the shutter, I cannot see how that force can be transferred to the film position.　
 
Are you sure you have a sturdy enough tripod and head? I'd look into that possiblility before looking for a new camera.

Not to the film position Jon ... it just makes it more likely that you are going to move the camera slightly on the tripod or move the tripod itself on soft or unstable ground!

I actually checked the Pentax with the back open and with the multiple exposure lever activated the initial movement of the advance lever rotates the take up spool ever so slightly!

I guess I could just get a roll film back for the Graphic ... I hadn't thought of that until now.

I remember you wanting one a year or so ago. Check out ebay. They seem to be going for less now that then. I even thought about contacting you when I acquired an extra one unexpectedly, but then gave it to my future son-in-law.

As an aside about that, prices on ebay seem to be very strange lately. Perhaps the impending 2012 sub burst is the cause. I see some cameras listing for more than I think they should, while others seem to almost be given away. Still others are listed all over the map.

I guess I need to pay more attention to the phases of the moon.
 
Hi Johan,

Now there's a camera I'd never heard of ... the article was a good read too!

It never faiils to amaze me how many incredibly good MF cameras there are out there that in reality cost peanuts for what they can deliver!
 
10 lbs with the lightest lens fitted aparently! 😱

The 6x8 format would be interesting to use IMO ... 6x7 is very close to square and 6x9 is just too normal looking for MF! 😛
 
A workmate of mine has the Fuji 680, it a very nice camera indeed. Exceptional build. Very precise focusing. Nice optics. And swing and tilt. An LF camera downsized, with all the advantages of MF. I very nearly bought the very same camera, but recommended it to him instead, and he's one happy bunny.
 
Accomplish your task with the G690, GM670 Etc

Accomplish your task with the G690, GM670 Etc

No film movement.

Take your first shot
Close the dark slide
Remove the lens
Manually cock the lens
attach the lens
release the dark slide to open
Take your second (or more) shot

You never touch the rewind lever during this procedure, hence film is not advanced any amount.

This works with the early Interchangeable lens Fujica cameras.

I just tested it with my G690 and both my 100 and 65mm lenses.

This camera is all manual and not battery dependent in any way.

Did not see the Fuji G680 post above, but considered that camera to be capable. Then, thought I would try it with my old $300 beater Fujica G690. It works.

Keith, why not just load up some 4x5 film holders and use the Graphic?

I think I offered you the loan of the Graphic 6x9 roll film holder (4x5) a while back - that still stands if you'd like to give it a try. It's pretty primitive and the neg spacing tends to vary a bit (film tension issues probably).

I'm going to go on a limb and assume the Mamiya 7 is a similar setup to the 6. We got into this a few months back in this thread:

Seconded, thirded or whatever - just like almost every "electronic" shutter employed up until the mid nineties, it is spring driven and electronically timed.

IIRC Rollei were the only maker ever to integrate a all-electronic shutter into a interchangeable medium format lens, in the SLX/6000 system.
