leica r10 digital *** mount change ***

Just squeezing more and more pixels into the same space is always boring, regardless of who’s doing it (or how many are doing it).

 

My humble guess is 35mm FF's full potential will get maxed out around 28-30 megapixels, at the 5.5 micron pitch, that's about the stuff Nikon/Sony are doing now on their APS-C models - after that, we'll see major quality degradation when more pixels are crammed into the limited space.

 

It won't take too long to reach that point, in fact, the technology is there right now ... if people are ready to pay for it at any price, you can get it TODAY. So I agree with you that people should start looking at something interesting.

 

Perhaps that's the time we'll stop speculation and start taking pictures. LOL

When discussing a possible mount change keep in mind that there was a mount change between the Leicaflex Standard and SL, another between the SL and SL2, another between the SL2 and R3, and the most recent was between the R7 and R8. Despite all these mount changes all of my lenses fit and work perfectly on all of my Leica reflex bodies from the Standard to the R8.

And the Schneider PC Super Angulon will fit any Leica/Canon/Nikon mount close to 35 mm format with the right reartube

Yes, I am also worried if they change the lens mount and may be we will have to dump our Leica R lenses we have now but if Leica is not stupid, they should not change mount so that we buy their new camera R10 being able to use our current Leica R lenses.

 

I want to have more comments in this thread as I see it has been several months people stopped commenting on it. Any new ideas, thought, and info guys?

Kodak currently has two pixel pitch options 6.8 and 9 micron for larger format sensors, so it's either 10MP or 18.7 MP on 24x36mm. I guess if they want to do something fancier they'll probably need to upgrade their stepper and peripheral processes as well.

Hi sdai,

Kodak also has 7.4µm, 5.4µm, & 4.75µm pixel pitches found in the KAF & KAI sensors. A lot of their sensors are composed of 13mm X 17mm tiles or 4/3rds sized stepping units. The M8's sensor is two units joined along the long side and I speculated that the "larger than 35mm FF" sensor could be a 4 X 4 array, as in two M8 sensors joined along the long side. This, of course, might only be valid if Kodak is the sensor source and doesn't rule out a new design with its own pixel pitch. So, who knows?

One cam.... two cam.... three cam.... ROM.........mount changes is just a family tradition:D

Describing the sensor in the M8 as comprising two units is a bit misleading, I think; it is just that the sensor has two read-out chanels, one for each half of the sensor. This is pretty much the standard, but there are also sensors with 4 read-out channels or more. Still, I have never seen a CCD divided in more than one dimension, so a 4 by 4 array would be quite unusual, to say the least.

I got carried away and the 4 X 4 should have been 2 X 2. The silicon blank would be exposed in four passes, each one laying down the approx. 13mm X 17mm segment of the final whole sensor. It would be like making a 2 X 2 panorama (or a 1 X 2 panorama in the M8's sensor). The read out channels may be for read out speed, rather than anything to do with the way the sensor is fabricated, so the final read out channels might be 1 X 2.

Sorry 'bout that.

If Leica makes a mount change and makes the new one bigger than the old one, it shouldn't be a problem to also design an adapter. Think Leica M to LTM.

 

I also believe that Leica can introduce AF lenses with the current mount. If my memory doesn't fail me the current ROM contacts provide more than enough information to the body to make this work.

 

Personally I don't see Leica changing the mount, unless they really are serious about introducing a new format that is somewhere in between 135 and medium format. Are we talking a digital incarnation of the 127 format here? Superslides anyone?

If an R10 has a larger diameter mount, there will very likely be an adaptor for current lenses to operate, hopefully, with full function.

 

Anticipating the prices for an R10 and new lenses, especially given the rotten E/$ exchange rate, I am concerned more about backward compatibility, that new lenses be useable on film Rs. Besides price, those of us who would likely wait a while for bugs in cameras to be worked out may be willing to buy a new lens before buying an R10, that not to say that automated lenses won't have bugs.

 

My hope is that there will be no issue regarding forward or backward lens compatibility.
