Lens Table ?

Well, I cannot imagine any sensor filter being millmetres thick.

 

There have already been a couple of photos shown here taken with a 15mm Voigtlander.

The Leica Q3 is available for pre-order at B&H Photo Video and Adorama

1. Probably

2. No, the lens code will be specific to the model - the code for a pre-ASPH lens will be different to the code for the ASPH version.

 

With 6 bit coding, the M9 can distinguish between 64 different lenses. If they utilise one code for every applicable lens model, will they not run out of codes?

Unlikely in the short to medium term as they also take the selected frames into account, so you could have exactly the same code for a 28mm, 35mm and 50mm lens if need be.

Ah, I see, so it actually nine bit coding, where the three last bits come frome the fram selector.

And even if they add an extra bit or 2, they can make sure the new lenses' first 6 bits are 'valid'.

 

E.g. old 35mm lux codes as 100100, new and improved one codes as 10010011, thus old cameras will still see the lens as an old 35mm lux and not mess up any corrections.

I asked the Leica rep today about compatibility with the CV15 and Zeiss 18. He said that 1) he didn't know and 2) caution is in order due to the thicker sensor filter. Has anyone mounted these lenses?

 

Nothing strange that a Leica person doesn't worry of 3rd parties lenses... but if you have the lenses, a caliper, and a discrete skill in using it, you can measure the length from flange to back element most protruding point and confront it with the most "critical" Leica lenses in that sense, that are officially compatible with M9 (probably, those measurements have been done by someone, maybe even in the forum, and published).

All collapsible Leica lenses can be collapsed. Except possibly the old 90/4; I don't have that one but it collapses a fair distance. A friend has 4 right now so I could check it, I guess.

 

In any case the 21/3.4 fits as well as the 15/8 although the rear element comes very close to the shutter. Whether the 15 works though is debatable as those poor little microlenses might be stretched too far.

Dear Henning,

 

if you could check it for me, it would be highly appreciated!

 

Thanks and best regards,
