Been thinking the same thing. By the way, there are 2 batteries and a charger headed your way for tomorrow delivery.Steve,
About time you got around to our state. We don't seem to be getting much respect down here since we decided the "hanging chad" election. I'll plan on coming up to see you and trying out some of your goodies.

The only more problematic issue for you, Guy, may be missing both her birthday celebration AND wearing the numbers off your credit card(s) with even more toys you buy :bugeyes: :ROTFL:We will just drink a lot that night so i don't feel the pain of the Voodoo needles.:ROTFL::ROTFL::ROTFL:

My first reaction to your file, as well as to Thierry's garden shot was that things were leaning toward underexposure by a stop or more....
... The underexposure may be real and designed to prevent blowing things out, much like Nikon film cameras always were. Not a bad thing in the case of the Sinar files.

Thierry,
I understand what you are saying. Thank you for the clarification on how the Sinar Hy6 and back record the meter reading. The use of the correct metering mode, and the placement of the metering patch is important to getting a proper reading for correct exposure. How sensitive those areas are (average, center weight and spot) can be critical. My own observations with different camera systems is that the meters are "tuned" to yield a best approximation for exposure, but some err more toward slight over-exposure, such as Canon has recently, while others may chose a slight under-exposure, as Nikon has for many years and models, even today. I am not suggesting that Sinar is doing the same, but it would not surprise me if their metering method had its own correction. That is fine if it does, and one just needs to learn a preference.
In David's shot, it looked as though the sky was dominating the reading, hence the darker image that showed what I would call under-exposure. What is interesting is that a larger portion of the image is actually a darker subject, so one could expect metering to boost exposure to compensate. If David was using area or spot and had selected a portion of the image with more sky, his original exposure looks about right....a couple stops dark to compensate for the sky. If he was using an average reading, I would have thought it to be a bit brighter overall to compensate for all the darker foreground, but that would just be a guess or speculation on my part, not knowing what kind of "pattern" for reading, and how sensitive each is on the Hy6 and Sinar back.
So, my apologies if it sounded as though I was attributing something to the Sinar kit that was beyond actual or design. It was just my impression from seeing David's image. Still does not take anything away from how robust the files actually are, and how much detail and DR they contain. That is all good. I know that you said you had purposefully underexposed your shot. My impression upon opening the RAW file you posted was that it was at least 2 stops darker, and it also already had some brightness applied already, so I was guessing total underexposure of nearly 3 stops. Only you know for sure what the real light was, and what you specifically metered, and I am not challenging that at all. I am merely giving my "guesstimate" of how much underexposure both images appear to have from my own experiences of working with lots of files (not Sinar).
Does that help explain my comment and set things a bit straighter?

David, as I am still seriously considering this whole end of the spectrum to replace my RZ/Hassey-V 6X7/6X6 systems for studio and some location work (the H3D-II/39 645 will remain in the arsenal) ... I have a few questions.Still learning this new kit folks so don't expect the best that this back has to offer yet. Anyway, went down to the train bridge this evening to see if I catch a good sunset but no dice. So I shot the bridge instead. This first shot was underexposed by about two stops. So I bumped exposure up by two stops in Aperture to see the level of detail that was available. The third shot is a crop of the second to show the detail. My early impression is that this back generates excellent files that can be pushed hard in processing. A valuable feature for me

In the 3rd detail image you posted there is noticeable red fringing on the edge of the sign and other areas where the sky butts up against a darker edge. What lens was used for this shot and what are your thoughts concerning this?
I ask this because it is an issue that can present itself when using strobes to back light products, and can also manifest itself when shooting items with specular highlights like jewelry or many highly finished industrial products ... all of which are frequent assignments I would be using this gear for.
For example I just completed an assignment shooting a bunch of 2009 GM wheels that all had to be backlit to knock out the neg. areas because they would be appearing on a white catalog page. CA or color fringing is not an option even if correctable in PS because the quantity of images precludes such additional labor... and the client has an eagle eye for such things.
I would show you an example of this except I need prior approval because of a non-disclosure agreement ... these are 2009 products not yet public.
Your thoughts?
Ah well, at least the Sinar has a C645 mount and can be mounted on the Alpa (yes??)

Victor,
Plus if you go for a P30+ for your Contax system you will have up to 1600iso.

Don't know where you got that impression Victor but these pics should answer it for you. Contax has RRS L plate and prism finder making it larger, film back is obviously smaller than digital back. Hy6 has a RRS plate on the bottom as well. Both with their respective 80mm lenses. The Sinar is obviously smaller but when you change lenses, e.g. 110 F/2, the Sinar can catch up pretty quick weight-wiseDavid, am I wrong? but you have had the Contax, yes? isn't this quiyte a handful compared to that?
