Finally tried the Leica R - Adapter M 14642 on the M.

 

Strange behavior when choosing 21-35, 28-90 and 28-70 manually in the menu.

 

When I push on Info button, it shows correctly :

 

3,5/21-35 mm R

2,8/28-90 mm R

3,5/28-70 mm R

 

When I push on Info button when playing a picture, it shows :

 

3/21 mm

2/28 mm

3/28 mm

 

for the same lenses.

 

No such discrepancy with the other R lenses and R zoom lenses in the Menu.

 

4/35-70 mm shows 4/35 mm

2,8/70-180 shows 2,8/70 mm

3,4/180 mm shows 3,4/180 mm

etc..

It cannot be the adapter- it does not convey lens information.

Regarding Arca-Swiss style plates, the RRS Camcorder plate fits perfectly the Leica Adapter tripod mount.

I know, it is the camera FW.

 

I suppose it will be the same with a coded Novoflex adapter.

Basically it only gives the shortest focal length so it should be just a matter of adding to the string and changing the aperture..

Correct, it only gives you the lowest FL for any given lens. A royal pain in the ass, but that is what you get. There is no electronic nor mechanical connections to let the camera know the FL you are using.

 

When I see this I NOW try to make sure on any given outing that I do not take any lenses that have the same lowest FL so in the end I am not messed up. Luckily there are few overlaps in FL in the R system that I own.

 

Hey, don't complain you only had to wait 15 months to find this out and you got a tripod mount on the adapter.

The RRS B9-E mounting plate is another alternative for the R Adapter M's tripod foot. It also incorporates an anti-twist feature.

Yes but why is the aperture recorded in the pictures taken with those 3 zooms only (21-35, 28-90 and 28-70) wider than their widest real aperture ?

 

2/28mm instead of 2,8/28 mm when using the 28-90 mm.

Curious given that Leica never made an R-28/2 let alone 28/3 or 21/3. Would someone be kind enough to explain to me how those data can be seen in spite of the adapter conveying no information?

[algrove]

They are seen when on auto lens detection ,the camera detects the R-M adapter. You then hit manual which it is automatically shown when the adapter is present. Once you hit manual the list of supported R lenses is displayed. From this list, one selects the lens you are using. If you take a shot then when pressing Info, the data shows something strange, but on a vario only gives you the lowest FL of the vario lens and in this case of a few lenses it incorrectly shows you a strange minimum f stop.

Thank you Lou.
