Without the ability to read the selected aperture, the camera can only meter at working aperture.... which means that the user needs to open the lens up to focus, shut the lens down ( this is all manual manipulation of the aperture setting), then take the image...... not exactly smooth operation...... or use the lens at full aperture.... which is a more specialized solution.... In the 60's, when I started to take pictures with my Miranda SLR, this technology was already replaced by lenses that at least had the ability to have a preset aperture.... you spun a ring around to reach correct aperture,,,, without thinking at least... I think that the Exakta camera offered this in the 50's, and the Pentacon ( first SLR) had this feature in the 40's (?) Novoflex either does or will offer a similar functionality that may not read the lens FL ( which is only useful for some lens corrections ( LR will do this automatically as well IF you can remember what lens you used..) and for putting the data into the EXIF fields... for what has been their price of around $200 Or buy a Chinese knockoff with the same capability for about $20...... SO the real choice is.... spend $750 on the Leica adapter or $20 on the Chinese adapter..... Each has about the same functionality..... They must be kidding......we MUST be not understanding the complete picture..... A few weeks will put some of these into users hands, and we can find out what the thing really does.... or does not do..... Frank Filippone Red735i at verizon.net There is no aperture control, all it can do is read ROM data of focal length - seems a lot of money (even by Leica standards) for what it is! john -----Original Message----- Apparently it is starting to ship.. BUT.. "The Leica R-Adapter L cannot read the selected aperture set on the lens. Instead, the camera uses the same technology to estimate the aperture as with M-lenses mounted via an adapter." There is still no info that I can find that says the lens aperture is open during focusing, then closed down during image creation... And the inability to read the lens' aperture setting is disturbing...For $750, you would expect more... Frank Filippone Red735i at verizon.net
