When Leica puts in a new MM sensor is it a Kodak?

If the MM sensor get corroded does Leica give you another Kodak sensor that will tend to corrode?
Rather unlikely given that Kodak has gone bankrupt a few years ago. They will, for the time being, replace it by a sensor of the same specifications, however.

Kodak's sensor Division was sold several years ago and became "Truesense". That in turn was bought out by "ON Technology", the same company that bought FillFactory. It is the same sensor, made by the same group, now under a different name. Like most sensors, it is revised and improved throughout the production run. The KAF-18500 is the only sensor from ON Technology using S8612 glass, the company is experienced using other glass. This Group has been bringing out new products since being sold by Kodak, including CMOS sensors available in both color and monochrome. They tend to cater to the technical and scientific market.

Anybody want to know how many KAF-18500 sensors are in stock? Updated 12/27/2014.

There is no sensor which does not blow the highlights. That's the way sensors work. If you have blown highlights, your picture is overexposed.

 

Sure, just MM is more prone to blown highlights. They need to make it more film like. Cleaner shadows without all the noise and better highlights.

It is not more prone. RGB sensors use three channels that may not blow at the same time, that is the only difference. The raw conversion software will attempt to reconstruct some detail from the remaining channel(s). The Monochrom has only one channel, so this trick cannot be used. That goes for any monochrome sensor.

 

All sensors blow highlights, You cannot fill a sensel with more than 100% photons. It is just the opposite of film. There you hit rock bottom in the shadows when it blocks by making a sold layer of Halide Crystals. Except of course slide film, which reacts the same way as a sensor.

 

The onus is on the photographer to adapt his technique to the medium....

 

BTW, my shadows are pretty clean on the MM.

The noise you complain about is in fact exactly what you are wishing for in the highlights. Sensors have a soft roll-off in the shadows.

I cannot see the noise that you see in the shadows. Guess I'm getting old

But perhaps you shoot at 1250 or higher and then you clear up shadows. That's a good receipt for noise; and banding too
