Well, first of all I must greet all the nice people of this very interesting forum: Hello!
We are about to buy a Sinar P3, but we have a great doubt about what back to buy.
The alternatives are:
• Sinar eVolution 75H (33 Mp)
• Leaf Aptus 65 (29 Mp)
The difference of resolution is not a lot and has not a big influence on our choice
The difference of price is a little influent (about 5000 euros) but not so much because what is more important for us is the quality of the generated images, and the easy way to use the back.
We are an advertising agency in Kiev, with a photo studio. Our works are from still-life, interiors, people to fashion.
According the experts of this forum, what is the best solution?
What are the pro and con of these backs (eVolution has no monitor and can't use a flash card, and must be used with a computer, for example... is this a con? What about 4-shot and 16-shot modes?)
I thank you for you answers.

Dear Alain,
I think first you ave to define your needs and the use of it.
You are speaking about quality: I can assure you that a multishot back will give you the ultimate quality and the best possible files, whatever one tells you. Any single shot has only one basic colour registered for each pixel, thus missing 2 basic colours. The interpolation is doing the calculations of the 2 missing colours and thus will produce more or less accurate files depending on the subject, with more or less artifacts and/or Moiré issues. The multishot function makes sure that each pixel gets the information for the 3 colours (atually 1xR, 1xB and 2xG), thus there is no interpolation or guess work necessary to find out the 2 missing ones: you get a file with true colours, without artifacts and no Moiré.
However, the multishot can be used only with stills, not with moving subjects.
One imortant issue when shooting in multishot mode is the choice of the lenses: you need digital lenses on the p3. The HR (High Resolution) digital lenses built for the p3 are the one giving the best possibe quality in multishot mode.
The eVolution 75 with its 33 MPx is the latest multishot from Sinar. Beside its multishot function it can of course also shoot in single-shot mode, however tethered and with no display. Though the design is small and handy and it makes it a versatile back for ultimate quality in studio and on location or for fashion shooting on location.
To get an idea from a user of the real quality and difference between a multishot and a single shot file, you can contact Rainer Viertlböck (rehnniar on this forum): he has very recently shot a very critical job for which utimate quality was required by the customer. After a few tests between single and multishot, the results have shown that he could achieve the best only with the multishot. Contact him and he will be certainly be able to show and explain you the differences with some examples better than myself.
Obviously, and if your main work is fashion and on location, then I would rather recommend a singleshot only back, like the eMotion 75 (33 MPx), with its fast shooting rate of 1.5 frame/sec, without buffer and without slowdown, having an internal hard-state memory of 6 GB beside the normal ossibility of use of CF-Cards. The display of this back is among the brightest you can find, viewable from any angle: it is not a LCD-display, but an OLED-display.
So, it is defintively a question of what are the needs you have: a single shot would certainly be better in terms of portability and for untethered work. However, only a multishot back like the eVolution 75 can give you both, single shot and multishot in Studio for the ultimate quality.
Both can of course be used on a p3, and adapter plates are available for any common MF cameras.
I am at your disposal if you have other questions.
Best regards,
