    Phase One on a Speed Graphic...

    ... Is there a way to do it?

    Kind regards,

    Re: Phase One on a Speed Graphic...

    Pro Adapter, Mamiya 645 Back to Large Format 4x5 Adaptor - Sliding with Focusing Screen - fits Cambo, Linhof, Calumet, Horseman, Omega, Toyo, Kodak with graflok back on Mamiya M645, M645 1000S, M645J, Super, Pro, Pro-TL, 645E, 645AF, 645AFD, 645AFD I

    Assuming the Speed Graphic has graflock back and that the shutter can be kept open (the speed shutter, the lens shutter must be working).

    I am going to try this on a Crown graphic.

    Thanks Martin - the lens on the camera has no shutter. I'd be reliant on the focal plane shutter of the Speed Graphic...

    Yes indeed it should be possible to use the focal plane shutter, but this whole thing has kept me to stay away from the speed and I now use a Crown.

    Phase one had the Flex adaptor but i don't know if it is graflex and then it has to have the appropriate digital back plate.

    I think you'd have a problem with this combination - Graflex hasn't issued a firmware update for the Speed Graphic in over 50 years.

    Seriously...does the FP shutter trigger a flash synch port? That's all you need, I would think. And perhaps some playing with the back's latency, as the shutter opening is probably delayed for slower bulbs rather than for instant electronic flash.

    BTW to my mind comes that Kapture Group also has sliding back adapters for 4x5. These are the real Rolls Royce of the adapters and the third option.

    Yes this is very important and was something I also thougt of in my first post.

    Re: Phase One on a Speed Graphic...

    Been thinking about this, and worst case scenario, the following should work no?...

    Physically mount the back (e.g. as per Martin's link) to the Speed Graphic.
    Connect the cable from the back to my ALPA FPS.
    Select a long shutter speed on the FPS.
    Fire the FPS shutter.
    Fire the Speed Graphic shutter whilst the back thinks it's being exposed by the FPS

    Re: Phase One on a Speed Graphic...

    Umm this suggested setup makes my brain smoke

    How about a new cheap lens with shutter and functional X-sync,
    in addition to a adapter ? LF lenses are usually dirtcheap and mounting
    it in a Graphic lens board is quite easy.

    The 'only?' real benefit of the Speed's FP shutter would be if one likes to try out an old Pezwal lens without shutter and mount it on a Speed.

    It's not the camera that I'm interested in really - it's the lens that comes with it.

    Why mess with the timing of the shutters? Just open the shutter on the back with a longer exposure and set the real shutter speed with the focal plane shutter, just like you would do with film.

    Kapture Group makes a gadget which you can use to activate the digital back (so it thinks it is taking a long exposure), then you could use the focal plane shutter on the Speed to shoot, and then you deactivate the back via the Kapture Group controller.

    I use it often for interiors when I need multiple flash pops to balance out a scene. Here it is:

    Re: Phase One on a Speed Graphic...

    I am very interested in this thread. What does everyone perceive as the advantage of mounting a digital back to a speed graphic?

    I should stress that the only reason I'm interested in doing this is because of the lens that has been adapted to work on the camera.

    I'm looking into whether or not I could get the lens adapted with an ALPA mount, but that would introduce its own problems.

    Kind regards,

    Gerald.

    The lens on my Crown Graphic Special is a Rodenstock 135mm f 4.5.
    I doubt if this lens will be sharp enough for my HD50 digital back, but I have wonderful memories of using this camera when I was young. The flip side is when I look at some of those images today, they don't compare favorably with what can be done today

    If you are just wanting the lens, then Novoflex tilt/shift bellows might be a good idea. They have all kinds of camera and lens adapters.

    Novoflex - Tilt-/Shift Bellows

    I would simply have the lens mounted in a copal shutter.

    Re: Phase One on a Speed Graphic...

    OK, so the camera has arrived, and I think I've worked out what I'm going to do...

    Back view...



    Front view...



    Back view with the back removed



    Basically, remove the Graflok (?) back as above, and then I'll get an aluminium plate made to cover that back plate, with a circa 9cm by 9cm hole cut out of the middle. I'll then get a Alpa 6mm spacer fixed to the aluminium plate so that I can mount the FPS.

    Simple, eh?

    The image on the ground glass from this thing is like nothing I've ever seen before

    Gerald,

    What on Earth is that lens? From an aerial camera?

    The lens history is uncertain. Apparently the seller bought a handful of them from a lens dealer and then built the custom mount to put it on the Speed Graphic, but neither of them know what its origins are.

    135mm f/0.95. No aperture, no shutter.

    I'll bet it's from a ceiling-mounted electronic projector, the sort used in lecture theatres.

    I have a Sony 135mm f/1.0 data projector lens which is rather like yours, except probably a bit more recent (it includes aspherical elements). I use it as a colossal medium format slide loupe! The unit I scavenged it from had 3 of these lenses, each with different multicoatings - one presumes they were optimized for R, G and B respectively.

    I was thinking along these same lines earlier today - that maybe it had come out of one of those old projection TVs, or a big projector, and have been doing some digging around. What you say makes a lot of sense given the lens characteristics.

    Kind regards,


    Gerald.
