Evolution of LTM to M adapters (post Digital M)

[larrytok]

Just an update to this thread with the release of M240 with Live View.
Some users have reported that they got an error message of "No Lens Connected" when they tried using some LTM lenses.

I believe the problem is due to the fact that for LV to work, the 6 bits sensor on M240 need to be "covered" over. The older adapter (e.g. Voigtlander Type I) with 1/3 of the flange cut-out will leave the sensor uncovered and this lead the camera to think that no lens is attached, thus the error message.

To solve the problem, use an adapter that has no cut-out like Voigtlander Type II (see above for limitation for some lenses) or adapter with 1/6 to 1/4 cut-out like Kipon or Metabones. These latter adapters also have recesses milled for DIY 6 bits coding.

I would also like to highlight the Note: in M240 Manual page 162 (Red underlined)

For Kipon, probably can order from ChiifCamera locally. Metabones adapter, you can buy them directly on their website. Of course, eBay is another source.

With new firmware v2.0.1.5 on M240, "cut-out" LTM to M adapter will work now according to pdf accompanying firmware:
Live view is now possible with every lens (including older screw lenses via an adapter) using "manual lens detection"

Interestingly, the Kipon and Metabones 6 bit adapters which were working fine on my M8 somehow somehow didn't register lens information in the exif with my M240. Was in the process of trying to experiment to find out the reason. However, with this firmware update, the Kipon and Metabones adapters now work fine. My mystery solved.
