From the thread below, here is the consensus for a M digital.

 

Most feel it should retain the characteristics and feel of our beloved M,

and only have the essential features needed for digital capture, not all the

bells and whistles of today's Digicams

 

It retains the form of an M, but eliminates the rewind and advance levers.

The counter would remain where it is, but electronically indicate what

shot you are on.

 

The 8 Megapixel CMOS sensor would be smaller than 24X36 because

the distance from film flange to sensor is narrower than most other

cameras causing problems with light hitting the sensor on an angle. But

the image proportions would enlarge directly to 8X10, and all the current

lenses would work with something like a 1.5X factor. So, there would be

a new bright line .092 finder to indicate what was being captured. No

electronic finder, just an optical one like the current Ms.

 

It would use the space where film now goes for a rechargable battery, and

the additional electronics necessary to digital capture, (if they can fit it all

in a camera the size of a G3, they can do it here).

 

There would be a 1.5" LED in the rear that is automatically programed to

indicate overexposed areas. The only menu options would be a

Histogram, Color Temp/White Balance, File size and type. (K.I.S.S.).

 

Shutter speeds would be increased to 1/4000, and sync to 1/250th with

HSS TTL built in for fill flash using a Metz.

 

I'd call it the Leica M8, for 8 megapixels (and it's the next number up for

the M.)

 

Thanks everyone for the input. Anyone know the e-mail address of

Leica's Boss Man?

 

Hey Jack, you lurking out there? Would this bring you home?<div>004Nly-10995384.jpg.b106cd1916780b6657ee908ccc61674a.jpg</div>

Roger, an 8 meg sensor would give you a 46 meg 16 bit Tiff file without

any grain to deal with. An electronic finder is not necessary to delete crap

files. The LED review screen is for that . By retaining the current

rangefinder system you retain the shooting characteristics of the M, and

do not need to introduce lenses with electronic contacts to communicate

with the body....all current Leica glass would work on our M8. Plus, the

idea is to suppliment film Leicas with a digital M for times when digital

would be a good solution.

Before you send this in, all you need to do is estimate the potential market for it. Percent of current active Leica users who would buy this as a backup and alternative plus collectors, and then some estimate of how many new users would be attracted to it. Seems to me that the current user base would justify the camera. If it really does reach an adequate level of quality, I would certainly buy one. An interesting question is whether or not the quality difference and/or style of photography (retaining the bright viewfinder and "instant" shutter)would bring in Fuji, Cannon, and Nikon users who are unhappy with their "digital solution," and choose not to buy their next "new and improved" upgrade. Right now I'd rather spend my money on a new Leica lens than the latest $1000-$2000 digital camera.

Jean-Christophe, simply use a VC 15mm =22mm, and use a 21mm clip-

on finder.

 

Robert, the lens X factor has no effect whatsoever on the speed of the

lens. The size of the sensor is smaller than the coverage of the lens, so it

sort of "crops' in a bit. A 50mm Noctilux then becomes a 75/1.0 !!! with

the same DOF characteristics of the 50.

Stephen, as I understand it, the rear elements of Leica M lenses are closer

to the film plane than an SLR, which has a mirror box and thus a greater

distance to the lens flange. Light is bent to strike the film surface across

the whole 24X36 area, and film is sensitive to any light regardless of

direction. Digital sensors, on the other hand, need the light waves to

strike more dead on (think of them as microscopic light buckets). I think

the Fovan sensor would be even worse, since the light has to penetrate

into layers of R, G and B pixel "buckets". It has taken a huge feat of

engineering to even make the full frame SLR sensors work. That's why

most were smaller than 24X36 up until now.

 

The little P&S cameras you are refering to have tiny sensors like 2/3"

wide with lenses especially designed to make light rays strike straight on.

Even the latest, greatest Canon G3 with it's 1 1/8th" sensor has a zoom

that is only the equivilant of a 35mm at it's widest end.

 

The objective here is to make a digital M that will use our exsiting lenses.
