    I have recently spoken with Ricoh about the upcoming GXR Mount A12 (official name for the upcoming m-mount module) and they have agreed to answer questions people have on this module.

    You can now read Ricoh's responses to the questions here: Cristian Sorega Photography: GXR Mount A12 - Q&A with Ricoh

    Here a few extracts:

    1. How is it possible to identify a compatible lens?
    - There is a lens checker included with the mount and in addition we will inform our customers through our website, Digital Cameras / Products | Ricoh Global.

    2. Are there any known lens incompatibilities?
    - Yes, the Hologon 15mm F8 from Leica.

    8. Does it do focus confirmation, and how is that implemented? Will there be some type of "peaking" function to aid in MF?
    - No focus confirmation, but there is a ‘Focus assist function’ which allow you to view the peak contrast point in the picture display.

    10. Can we hope for a sensor without the anti-alias filter (like the sensors in Leica M8/M9), or at least a sensor with lighter anti-alias sensor?Can we hope for a sensor without the anti-alias filter (like the sensors in Leica M8/M9), or at least a sensor with lighter anti-alias sensor?.
    - This sensor does not have an anti-alias filter.

    14. What is the timed shutter range? Does it support Bulb? What is the maximum exposure length?
    - The focal plane shutter has range from 1/4000 to 180 seconds
    - The electronic shutter has range from 1/8000 to 1 second
    - The focal plane shutter supports both bulb and time, and its maximum exposure length is 180 seconds.

    16. What is the shutter design, horizontal, vertical, cloth, metal, etc.?
    - The shutter is a vertical-running type, and metal.

    26. Can it do sequence capture? How many raw exposures can be made in sequence, and at what speed? How many JPEG captures can be made in sequence and at what speed? Is the interval shooting supported?
    - Yes, sequence capture is possible. In RAW mode 4 images (with noise reduction off or weak) can be made in sequence. In JPEG, 2.2 frames/sec can be captured. Finally, interval shooting is also supported.
