Fuji X100 Digital SOMETHING from Fujifilm

My memory might be fuzzy, but I seem to recall an article by I believe Sony, explaining how the back illuminated sensors are most beneficial on the ultra small sensors like cell phones and point and shoots, and less on larger crop and FF sensors, I seem to recall it even saying it might be near irrelevant on FF sensors. Take that with a grain of salt, but maybe this jogs someone's memory with a link to the article?

Are there any large sensor cameras out yet with back illuminated sensors?

If Sony said that, it's their marketing people trying to lower expectations for larger-sensor cameras.

Large backthinned sensors are DEFINITELY beneficial. (I use a rather expensive one on one of my research microscopes — >90% quantum efficiency :^) ). But they are still very expensive and they are (due to their thinness) very fragile. Not what you'd want to put in a D3 or any other cam that sees abuse...

Interesting - I kinda want your job now 😀
 
I can one up the geekery. This thread seems to have ventured into a discussion of shutter design of any camera and whether or not the design and placement of a shutter can have an affect on Bokeh.

Some shutter mechanisms, such as in the Minolta Hi-Matic E, affect Bokeh. The single-set of blades of the shutter control the full exposure. It only opens to the aperture required for the exposure, thus setting exposure time and F-Stop simultaneously. So the shape of the Shutter blades at opening, and the placement of the shutter mechanism within the lens, does affect Bokeh.

So- if a between lens shutter is being used on the X-100, it depends on the type of shutter used. If the shutter always opens beyond the selected aperture, it is not an issue. If the electronic between-lens shutter similar to the Hi-Matic E is used, it is part of the equation. I'm thinking that after this discussion, Fuji will absolutely omit Hi-Matic E types of shutters from the trade-space. But they do save space in the camera. Only one mechanism to execute shutter speed and aperture.

This would then co-incide with the article on the luminous landscape which stated that digital sensors couldn't make full use of fast lenses so manufacturers are raising the gain of the sensor to falsely boost the speed in lenses < f2.

This is extremely interesting to me... I usually only use fast lenses on my DSLRs and would love to know more...

Can you point me to the LL article you mentioned above. Thanks!
 
If you cut a couple of wedges into a focal plane shutter, and fire a strobe-light with a very fast rep rate during the exposure , the wedge shapes would appear as shown. The focal plane shutter takes ~1/60th of a second to travel over the image area.

Some more on the viewfinder:

Here is the direct link to part Viewfinder

Interesting

Nr.4:
quote: "The viewfinder magnification of 0.5 is generally considered the easiest to see in the case of a camera equipped with a lens with a 35mm focal length (135 equivalent) – not too low and not too high."

The "not too high" - seriously? Have you guys ever had the problem that the image in the viewfinder of the R3A was too big? 😕

On the negative side - not a single word about the manual focusing - I hope it will come in later chapters.

Manual focusing via the lens focusing ring.

Thanks. I knew about the ring on the lens, but only after reading the text I realized that focus confirmation (I mean - to actually see where the lens is focused) will be possible via the electronic viewfinder. So this should be similar to current digital mirror-less cameras using EVF, right? Let's just hope that the delay will be minimal (I never used EVF so I have no feeling about it).

I use EVF for manual focusing on my Pana GH1 and there's absolutely no delay.
I'm sure it will be the same with the X100.
What I'm waiting now about that camera :
- Silent shutter (does anybody have news about it?)
- black paint version
