Based upon known MTF data regarding the field diagonal (14.2mm) and disclosed 2:3 format, we can deduce the actual pixel size to be .0055mm and the most likely image dimension to be 4284x2856 to yield the stated 12.3MP sensor count. Using the disclosed MTF diagonal of 14.2 further yields an actual APS-C modified dimension to be : 23.63mm x 15.75mm.

Moreover, we can see the pixel density is (23.63X15.75)÷10=3.03MP/CM^2. This pixel density compares favorably with the NIKON D3s (Although the NIKON is a full format DSLR).

At a minimum, we can expect the Fuji X100 to yield very low noise images and since the leaf shutter will necessarily be quiet, street results should be very good indeed, especially in low light conditions.

Knowing the extent to which Fuji has proceeded to create a new class of digital camera, we can guess they will offer later in 2011 a longer range lens of say, 46-50mm actual FL. This would yield a 35mm equivalent of 65-75mm for portraiture and scenics. Fuji has clearly stated the target client is the advanced amateur & professional desiring a more convenient and/or less bulky alternative and that, by definition, will include studio/location portraiture.

Clearly, the lens design effort alone is exemplary as the MTF curves are very good at the fast end. I imagine even astrophotographers might sit up and take notice at f/2 and f/2.8.

Finally, the use of offset sensor lens geometry to compensate for light fall off is another example of the completeness of the design.
 
Since I am way too ignorant to come with this stuff, I can only assume that your post is damn well interesting.

Well, that is if the AF is fast and/or the MF is properly implemented. The X1 has a leaf shutter but slow AF... not exactly street friendly.

Do you really think they would put out a portrait only version? Aren't there better tools for that? In the past Fuji has only used wide angle to normal focal lengths (28-50mm equiv) for their fixed lens cameras. I'd imagine that won't change.

I don't think that bulk/weight is a big issue for studio photography. So there will be no demand for a very light camera with a fixed portrait focal length.

Who says it's going to have a leaf shutter? The shutter speed dial goes up to 1/4000th, and while it may be possible to create a leaf shutter that fast, I doubt we'll see one in the X100.
 
Interesting math in the original post here, but I think all we really know about the X100 is that Fuji has published interesting stats, demoed a non-working prototype and gotten a lot of people thinking about what their next camera will be.

I'm with jsrockit: If the AF is slow or the MF is futzy, game over. At least a far as street photography goes.

Nobody puts out dedicated lens cameras with anything but semi-wides to wides at this point. The world is getting more crowded, folks. Those who want portraits have to crop. :eek:
 
Extra info on Twitter

Extra info on Twitter

Picked up a a few of tweets from fujiguys blog

"Raw on #Fuji X100 can be process (raw conversion) within the camera itself. Working also to add 3rd party support for Fuji RAF file"

"Fuji X100 captures 12-bit RAW image using RAF file type. Converted using customized Silkpix s/w (supplied)"

"FN" button on #Fuji X100 will default to quick ISO selection. "FN" button can be reassigned to other options however"

Not too sure if this means that the x100 is 12bit only. Good news on the ISO quick selection options. Go Fuji!
 
The Fuji Guys are apparently trying to get to the bottom of something we don't yet know: the manner of focus control.

First related tweet says, quite confidently:

http://twitter.com/#!/fujiguys/status/15414996162838530

But they follow up with a less certain:

http://twitter.com/#!/fujiguys/status/16577188736278528

Fingers are crossed that this thing has a fixed, mechanical focusing mechanism. It makes focusing on-the-fly (usually for quick street shots) so much easier.

As an aside, who are "The Fuji Guys"?

Edit: The Fuji Guys seem to be members of the FUJIFILM Canada team. I'd say they're an automatic follow if you're on Twitter and are excited about the X100 in any way.
 
And also from the Fuji Guys: Any sort of focus confirmation in MF mode while using the OVF is TBD. Yeah, it's an easy answer, but Fuji's been pretty good so far with maintaining reasonable expectations. If the answer is TBD, I have to believe that their software engineers haven't yet ruled out overlaid "peaking", or some sort of other visual aid on the OVF.

Agree with this 100 percent. Not saying someone couldn't use one in studio. But I just don't know why they would.

Can someone explain why is the is a "new class" of camera that's good for studio work?

Fuji makes good stuff; I'd like a Texas Leicas, Fujiblad Pan X, and Bessa III, but I still don't see it being much more than a Konica C35AF with an APS sensor... I'm missing a lot of info.

Yes. It would be interesting, too, to know how many of those speculating in this thread have handled or even seen the thing. This is 'vapourware squared': an all but non-existent product hyped by the fantasies of internet fora.

It may be great. It may be a disaster. To quote HH Dalai Lama on the subject of speculation on the conjunction of the planets a few years ago, well before it happened: "I think we'd better just wait and see."

Cheers,

Sony needs a VF solution though.
A high quality optical viewfinder on a compact, large ‘sensored’ camera, like the present king, the M9.
It’s all about the high quality OVF, in Fuji’s case, the hybrid VF.
Simple ‘active optical viewfinders’ can incorporate Fuji’s projection LCD/prism/lens design.
Leica could adapt the design into their existing external optical viewfinder for the X1. The projection LCD, located in the base of the finder, would be used for the projection of camera data, including focus confirmation and frameline projection. (The external OVF would house the prism/lens/LCD)
Unlike Fuji, the small projection LCD would not be used as an EVF.
This ‘active optical VF’ would work great on a fixed lens, mirrorless camera like the (X1) while keeping the overall package compact.
I’m looking forward to seeing some ‘Active OVF systems’ being introduced on future mirrorless camera designs.

LEAF SHUTTER? The X100 site is quoting 1/4000 shutter speeds, this would be a remarkable technical advancement in leaf shutters.

The site makes no mention of any mechanical shutter and quotes probable 0.01 lag times ( I imagine a good mechanical or electro mechanical shutter should have 0.0 lag).
