"sorry - its not that simple. of course I HAVE done comparisons and used the LCC card, and there is no difference with my main camera set up (Contax 645) yes, I know thats a retrofocus wide angle etc etc, but the point is that there's a lot of Phase users (the majority?) who are like me, use MF DSLR's, and dont see LCC ever. I'm sorry for those who do suffer, but please remember its non-existent as a problem for a lot of people."

If the thread you started had been about a retrofocus camera then what you are saying would make sense Narikin.  Using the Contax as an example of how your Phase back does not have LCC is pretty much hijacking your own thread.  The Alpa does not use retrofocus lenses.  Can you tell us which lenses you have used with the Alpa and the Phase One back?  You must have done this before to declare that LCC is off topic regarding the use a an Alpa 12TC and the P45.

I have P25 since 2004 and upgraded to P45 earlier this year, use on my Contax 645 with every Contax 645 lenses with satisfied result, plus sometimes using the MAM-1 adapter to use some Hassy CF/FE lenses.  Since I also own the Alpa 12W and AlpaSW and have ordered the back adapter CO645 for my P45, I was wondering if anyone has the experience using the digital capture back with the 38mm Biogon and 48mm Apo-Helvitar?  I have not yet bought the digital lens yet, but I am content to continue to use Contax may be until the Hy6 becomes a stable platform - as I shoot mostly fashion, and just use the Alpa as a wide angle solution ( wider than my Contax Distagon ) so I my priority will be either a 24mm Apo-Digitar or 28/4 Apo-Sironar, hay one use this combination and can recommend?

Eric, with respect, there's been dozens of threads about LCC, and Leaf Centrefold issues, and this one really need not go over that ground again... this is a pro forum, so do you really think that nobody is aware of it here?

there's plenty of other issues in the question of using an Alpa with a Phase - back wakeup, handling, focus, operability, shooting style, shutter choice etc. so there really is no need to go back over the same old ground once again. we are not all ultra wide angle shooters, and personally I would be using an 80mm or similar on an Alpa, ie: not retrofocus. As already commented, Alpa dont make any lenses, so I can use what I choose, including the Apo El Nikkor I have mounted up in a shutter + focus mount. but whatever, I give up, its just another LCC thread now.

On the ALPA viewfinders. I was using the Linhof Multifocus optical finder that was made for the latest Linhof Technika 69 cameras. No distortion and incredible light gathering capability, also has parralax correction. ALPA can make a holder for it.

I don't have the camera any more but the small one with spirit level looks like it. You can see the finder mounted on the Linhof here: http://www.linhof.de/english/kameras/techn...ertechnika.html

here is the 4x5 finder at B&H:

Here is a 6x9 finder on ebay:

If you are patient you will be able to get one on ebay. New they are very expensive and I am not sure they are in production. I had a 6x9 film back on the Alpa so it was a perfect match with digital you might have to alter the mask (the masks are changeble and come in 6x6, 6x9, 6x7 formats).

I was wondering if anyone has the experience using the digital capture back with the 38mm Biogon


I regularly use a P25 with a Hasselblad 903 SWC, there's a very minor colour cast issue but it's easy to solve because with no camera movements possible on the 903 you soon build up a small library of correction shots at different apertures, portrait and landscape format, and different lighting conditions. The 38mm Biogon vignettes noticeably, and I get the impression the vignetting is more obvious with a digital back than with film. I've thought about a generic centre filter but unless these are matched precisely to one specific lens you can end up with a darker annular ring that's hard to edit out. Another reason for avoiding a centre filter is that the 38mm Biogon can't take two stacked filters and I often use a polariser.
