To make matters worse, don't Pookas and rabbits use the Mayan calendar?

Just returned from one of the bigger dealers in the Philly area where I asked to see a 1DMkIIN. They did not have any in stock and said that they weren't even sure if they could still order them but even if they can, they wouldn't be restocking them. The intonation was clearly that they knew something is coming but I didn't get any sense that they knew what it might be.

This is a store that would normally stock the 1 series? I know my local stores no longer cater to professionals, so no 1 series in stock.
It is extremely unlikely that Canon will release an MF (Medium Format) camera, which is 6x6 cm or 6x7 cm format (60 x 60 mm). Baby MF is 45mm x 60mm, though no film uses the full formats.
What is more likely is that Canon would extend the "full frame" to make a new EFplus mount. Canon could make a sensor something like 48 x 36 mm and EF+ lenses that would fit such a camera. EF lenses might not be mountable, just like EF-S are not mountable on EOS full-frame. However, if Canon did something clever with the mirror it could swing out of the way of EF lenses, and a top-level camera could afford an expensive mechanism. Sophisticated electronics could automatically crop when an EF lens is mounted, with masking in the viewfinder.
So I wish people would stop referring to MF. We will soon know what Canon will call it (I'm hoping for EF+ / EOS+), if it exists at all.
- FTFFFBLFTRMF ("Fuller Than Full Frame Format But Less Full Than Real Medium Format)
- SMF ("Semi Medium Format" or "Small Medium Format")
- LTFFF ("Larger Than Full Frame Format")
- EFF ("Enhanced Full Frame")
Most kidding aside, maybe just DMF ("Digital Medium Format")
All kidding aside, I think most people understand that digital "medium format" almost never is the same as film medium format, which itself is actually a collection of formats. Even the so-called MF backs have sensors that are smaller than MF film. Maybe the concept of MF simply expands to take in even more formats that it already encompasses.
Back to work...

48x36mm is considered standard "Medium Format" digital these days. I think it is an acceptable term. Hasselblad with the H3D series now calls their new 22MP and 39MP H3D cameras which use a 48x36mm "Full Frame Medium Format." Phase, Leaf and Sinar also call their 48x36 and smaller medium format backs "medium format as do Kodak and Dalsa who make the sensors. If you go to any medium format forum like LL or the old RG pretty much everyone calls this MF. If you prefer refer to these as cropped medium format maybe. These are all digital crops of the 645 medium format film based cameras and 645 is certainly part of the medium format family.
In the world of digital really we start to re-define the formats and think of them in different ways. So the meaning of the terms change with the technology.

Personally, I think the larger than FF sersor would be something that was 38x26mm (ie. extra 1mm in all directions). Now, imagine if you mount your 24-105mm f/4 L. The camera recognises the lens, and knows that it has some distortion and vignetting wide open at 24mm the exact amount is quantifiable, just the same way that ACR does it.. So the camera adds extra capture from the additional 1mm that would normally be outside the frame to correct for the distortion, and automatically adjusts for the vignetting.
After the shoot, exposure can be adjusted in camera, as can sharpness contrast etc. Effectively, the camera can do the RAW processing on the spot, with output to a different card. No computer needed all of a sudden.
Jpegs produced by the camera become final product. Sound feasible?
Does someone know what is the maximum sensor size which fits in the EF mount ? I'm not talking about the largest sensor for the lenses but only for the mount ? Cause They coul keep the mount, and do the crop mode for current lenses and build some larger lenses for soemthing like 40x30mm

The image circle diameter is just marginally bigger than 43 mm (diagonal of 35 mm still film camera frame). However, some EF lenses have baffles which limit their output to about 36 x 24 mm.

jpegs as the final product? Not interested.
Dan, the camera would still shoot RAW etc - effectively it would simply enable you (if you chose) to do RAW processing in camera. I imagine all the additional features enabled using the larger sensor space would be duplicated in DPP, and presumably by other vendors once released.
I think Canon will announce 2 new bodies on or before Feb 28th. Given the history of Canon rebates, it is almost a given that the 30D and 5D are priced to move. We should see a 40D and 5D Mark II with dust cleaning, higher MP 12MB+, higher FPS, improved buffer, new grip options, and Digic III. The 1D series will remain unchanged atleast until Fall 07. We may see a few new lenses in the EF-S mount and EF "L" series.
645 is smaller than 6 x 4.5cm. I could look it up, but I'm lazy. An "uncropped" lab print isn't going to the very edge. 48x36 is very close to real world film 645. Maybe a 1.1 crop. Close enough that it doesn't matter. MF digital is medium format.

Yes. Maybe we should just say 36x24 instead of "full frame" and 22x15 instead of "1.6 crop". From the point of view of most Digital Rebel owners, that is all the frame they know.
Additionally there needs to be some standard for referencing focal lengths to format too. Perhaps we have to get used to referring to Angle of View, AoV. Unfortunately, AoV as a function of focal length and format diagonal is a non-linear function. It gets old having to explain that 50mm is "normal" on "full frame" and "portrait length" on crop (meaning 1.6 crop), which will only get more complicated with an MF or EOS+ or whatever it gets called. 1.3 crop (actually 1.254 crop) is another kettle of fish.
Normal AoV is 46 degrees, portrait (h&s) is 28-29 deg, facial is 18 deg, sports is 12 deg, birding is 5-8 deg. Mild wide (full-length portrait) is 68 deg, wide is 75 deg, strong wide is 94 deg, and ultra-wide is 108 deg.

My 5D does in-camera raw processing now. What does yours do?
