Ok, we followed the press conference on the internet and this is a summary of it.
1. the whole stuff is still in the design/development status. They hope to offer it by autumn 2004
2. The size will be similar to to an R8/R9 with attached motordrive
3. The chip will be designed and manufactured by Kodak and Imacon exclusively for Leica
4. ISO 800 is a minimum requirement. They hope to be able to go higher.
5. The digital back is/are actually 2 parts. First the back itself with the chip in it, second the power unit which will be attached at the buttom like a motordrive. The latter one hold a Lio-Ion batter in it and the electronics.
6. Imacon developped a technique for this to minimize the power consumption and to reduce the noise level by 50% in the picture.
7. They say it needs around 1 minute to switch between digital and film ready to go position.
8. The pixel size is 6.8
9. There is no USB 2.0 (they think Firewire would be more important)
10. All lenses are compatible, but ROM lenses will be able to tranmit more data to the chip, so there might be some plans for future versions in the same direction as Olympus with calculating vignetting etc.)
11. There will be a protection on the chip, which can only be removed after the digital back is firmly attached on the body.
12. Problems with dust will be solved with a software solution. But they do not have that finished, so they can not tell any details.
13. They will offer a special viewing screen, which has a frame - well known with Leica M-cameras. Since the factor is 1.37, you can see what is going on outside of the picture.
Surprisingly Leica confirmed basically all arguments that Olympus used for the introduction of the 4/3rd system.
Leica confirmed that lenses, not specifically designed for digital photography, would show worse performance in the corners then the same lens with film. Since Leica uses the factor 1.37, the corners do not come on the picture anymore, only the center of the lens design will be used.
There will be no similar solution for the M-System, because of the smaller distance between the last lens element in a M-lens and the location of the chip, light rays would hit the chip in an angle which would result in worse images (this is no probelm with normal film). SLR cameras have a bigger distance and are therefore better to use. Fullframe for the R-system would not have been possible as long as they do not want to design a totally new body (and I guess also a new lens mount).
So the good thing is that they at least try something, the bad thing is that they (IMHO) totally misinterprete the future development in computerindustry.
I do not think that in one year or later you will find many computers with firewire. It is more likely that they will all have USB 2.0 or higher.
Also in question is the use of SD cards in the future.
I could live wit ISO range 100-800, but not with 4500 Euro. And 10MP in one year might sound differently than today.
At the end of the day, it seems to be a strategic move to announce all this now, over one year ahead. Hopefully they can deliver something really good by then or they will have the same marketing problem as Contax with the ND.
The question is, whether a Leica user will wait so long and will spend 4500 Euro in a digital back with afactor of 1.37. Or he might just by in autumn 2004 a complete new system parallel to his R-System for the same money with 10MP and incl. lenses etc.
Time will tell...
