New PHASE ONE 645DF Medium Format CAMERA

Dave, thanks for the Capture One 5.0 info. Hopefully this is for both Mac and Windows - correct?

Can you provide a little more info on the Uniform Light tool replaces LCC's and is applied.

What about compatibility with Windows 7 (release date October 22) 64 bit machines?

Much appreciated.

October 28 release for 5.0 - just a few days after we return from Oregon so we can all give it a workout processing the files from the trip!!!
I was told today that this is basically LCC with light falloff measurement and correction built in.

hmmm....I can smell another "Mancuso kit swap" coming.....

AFDIII for 645DF
P30+ for P40+
80mm f2.8 for the 80mm f2.8 LS

Just cannot imagine Guy NOT wanting to do this ;-)

LJ
Nahhhh. You have it right, except for the lens part. I'm gonna bet that Guy gets the 645DF, P40+, and then the 110mm f/2.8 LS....
hey! Let's start a pool.....

:ROTFL:

I would see that bet and raise it with a 55mm f2.8 LS ALSO.....just seems like the right combo of lenses for group and portrait style shooting with fill flash used outdoors. :thumbup:

oh, Guy is sooooo in trouble....

I just ran out and bought a new knitting kit for my new 645DF designed ski mask. I will custom make a few more at 20 k each. Guarantee you won't get caught for at least 5 minutes after that I am not bailing you out. :ROTFL::ROTFL::ROTFL:

Most of it sounds great. I already see it coming that i will have to re create a few panoramics which had huge light fall off after a big shift.

However I would like to know TWO main things. Once will Live Preview work on Windows ? (As said before not everyone wants to work with slow mac based computers)

Second what about the shutter vibration with the new camera ? Any improvements ? Let me explain what I mean. As far as I have tried it is nearly impossible to get any sharp results using a 300mm or 150mm lens with shutter speeds around 1/5th to 1/20th. Even with a MLU and a cable release. I mean when you make a high speed film of the thing you see the whole camera vibrate when the shutter opens. I'm taking about the SHUTTER not mirror. Any improvements ?

Well, with SK glassand the specs looks like finally a real HB (and CTX :D) contender.

..but, are we assuming AF SK lens or are they like some of the high end glass (like 110 MAKRO), MF?

leaf shutter, if really AF with those specs-this must have been a secret project more secret than the M9.

looks perty good though :) even MF

Christopher,

See my 'tease' thread. I've been testing the new body and lens today and whilst it is clear that with MUP there should be a significant improvement at slow shutter speeds using the leaf shutter, I have yet to see real evidence of it: see these two 100% crops from the top (about half way to the left edge from the centre) of the frame.

The following is at F16, 1/5th of a second with the new leaf lens, MUP



The next is the old lens on the new body but with FP shutter, also at F16, 1/5th and MUP


I think this shows that with a good tripod (a Gitzo Carbon Fibre GT3541LS ) and head (Arca Cube) the benefits of the leaf shutter from the POV of shake are not significant. More intriguing would be the same test with a less stable (and lighter!) rig, which I no longer have to hand but which might show that the leaf shutter makes a difference with easier to travel with tripod and head combinations...

Victor, I have one here. It is AF, SK, and AFAIK PDG!

One question regarding looking for the benefits of the leaf shutter: I presume that the FP shutter still has to fire, so the question would be when? In a Hasselblad V, I believe that the blind shutter at the back opens when you pre-release the mirror, and closes when you release the shutter button, but it is relatively light weight, and would not, I think, have the kick of the Mamiya/Phase's shutter. In other words, putting a leaf shutter lens on a FP shutter camera doesn't turn it into a leaf shutter camera like a V, so the advantage of the leaf shutter lens would be much more for flash sync than for vibration reduction?

Actually, you'll find the V has a FP type shutter that works as a darkslide when you are cocked and viewing through the VF. Upon firing, the mirror goes up and the lens shutter closes, then the dark slide opens and THEN the leaf shutter fires. All to be repeated after the next shutter cock, which closes the FP darkslide before opening the LS on the lens. Similar on the Mamiya RB/RZ.

In some current LS/SLR systems, the re-cock is automatic -- and that's about the only practical difference to the above. However, I think the H3D body was maybe the first LS/SLR to do away with the darkslide since it is NOT needed for digital sensors -- and suspect that might be the case with this new FD body too. IOW the new Mamiya body may not be film-back compatible either, or it may have a special film mode that keeps the film protected, not sure which...

The other part about flash duration speed is separate. That should not matter so much, except for flash units that have a very narrow power spike (short duration for freezing action), which would then need to be timed more closely with the shutter duration.
I was just thinking it would be fun to see this on an oscilloscope... then realized that the electronics used for TTL flash control presumably are able to measure these short durations already.

How cool would it be for a future camera to have a "setup mode" that would capture the entire exposure duration, including flash pulse, and display it as a graph on the back LCD? Then you'd use the controller keys to fine-tune the sync timing (which already is electronically controlled) to position the flash pulse in the best position for your particular setup, giving you the highest possible flash efficiency with your specific power packs, radio slaves, etc.

Sound crazy? Hey, until this week nobody realized an accelerometer would be a good thing to integrate into an AF system, so who knows what might be tomorrow's great idea...?

Jack: I know about the V's darkslide shutter, I used to have one. I believe that tashley (Tim?) has commented upon the kick of the Mamiya/Phase shutter in the past, and the V's darkslide shutter is pretty gentle. He was doing tests with MUP/mirror pre-release, and on the V the darkslide shutter opens when you pre-release the mirror. Hence the question about the timing of the FP shutter on the Phase when using a leaf shutter lens. If the first curtain of the shutter fires when you press the shutter release, just before the leaf shutter fires, but NOT when the mirror is released, then you would still have FP shutter vibration, even when using a leaf shutter lens. If it fires when you put the mirror up, and you then wait for the mirror-up/shutter vibrations to die down, then you have a scenario very much like a leaf shutter camera.

Dear Tim

Sounds like a winner!!! Would love to see some images, and also your reaction to how the AF works.
"dead" systems don't last forever (to REALLY stretch a metaphor :bugeyes:
and committed to Phase (P65+) and considering a second back, I could easily go for one of CI/Phase deals for a PM body SK glass and second back (Dave, what was the cost to swap mounts? was it free the first year? :D

Anyway, the main thing for me has always been the glass, but with 66 YO eyes, I do welcome AF, and at times the Contax is frustratingly perverse in what it focuses on.

so, I say "good on them"; Phase may have a really strong future with this

best regards

Victor if you have the Value added warranty the mount swap is free. Normally I think the charge outside the warranty is 3k but the CI guys can tell you for sure and they can also tell you what warranty you have.

Yes, it will work with Windows and it works very well.

More wish book porn just to light Guy's fire!!
Thanks Jeff just what I need more incentive. LOL

BTW did anyone notice these look fairly small. I know hard to tell but they really don't look any bigger than a normal 80 in size. Tim can you elaborate on the size of the 80mm and it's filter size.
