No, not 100%.
There is 1mm space between the Lenshood and the table.

Don't understand your question, why is this important?

Not sure for Joachim but i dislike nosing down lenses personally.  Hard to avoid on compact bodies but my CV 15/4.5 v2 stands straight perfectly.

For me "noising down" oder "up" has no special importance.
I prefer chosing a lens because of its image quality!

Chacun à son goût ;)

So do i generally but lenses i don't feel comfortable with tend to stay at home or in the bag so i chose the CV 15/4.5 v2 for its compactness instead of v3. I'm pretty sure the latter is optically superior though but i don't use UWA lenses normally so i don't go wider than 21mm of full frame cameras. Now i do the same with other focal lengths to be honest. Reasons why i prefer M lenses are their IQ of course but also their size so i will never use a big lens on a small body if i can avoid it but it's just me :cool:.

Certainly not important. Just collecting advantages and disadvantages of the two lenses I am interested in. If it turns out that I am otherwise indifferent, small details might matter.

CV 15mm III is a joy to use. It is light and tiny. Its drawing is very pleasant. Stars are beautiful. Colours are very nice. 
22.5mm equivalent is an interesting middle ground between 21 and 24mm. 
But it is no match against TL 11-23mm awesome sharpness. 
But somehow CV 15mm III has more character than Leica’s Super-Vario-Elmar-TL. 
CV 15mm III also wins into MF and hyperfocal category. 

We should not use CL crop mode with 15mm. Due to lack of proper resolution to do so. 

CL crop mode is only for über sharp TL and Sigma lenses.

CV 15mm III is a star making machine. 
very easy to produce a star when shooting the sun. 
It is quite flare resistant. 
However it is very prone to nasty red dots flare. I guess that the bulbious rear element is the culprit. It is not flat, coating may not be efficient enough and it sits too close to the sensor. 
 

However lens is easy to use. But being wide angle 22.5mm equivalent and being slow f/4.5. Makes focus peaking not reliable enough. 
For some kind of reason. We should not use hyperfocale with this lens. You have to focus spot on to get good sharpness. Otherwise be prepared for massive loss of resolution. The image will be sufficiently in focus though. But it will lack the crispness of high acuity. 
 

VM 15mm III IQ is clearly inferior to TL 11-23mm. But it is cheaper, way smaller and cuter. 
For now it is a mix bag, not sure to keep it for my CL.

@cp995Which lens profile do you select in camera for Voigtländer 15mm V3 ? 
WATE @16mm or no profile at all ?

Yes, I allways used the WATE 16mm Profile.
It's really easy to code the Heliar 15 III as the bajonett has a deepening, where you can paint the code secured.
The 16mm WATE coding is only one black dot ...

Ok thanks a lot. 
 

Finally I chose to keep it non coded as an unknow lens. Just using Lightroom Classic lens profile at import. 
They have a VM 15mm f/4.5 III one. It works great and better than WATE @16mm one.

However the lens is really soft compare to TL 11-23. Not sure to keep it. 
It never reach 11-23 level at any aperture. 
VM 15mm III looks like a 12MP compare to 11-23 mounted on 16MP T/TL. 
It is absolutely no match to 11-23 mounted to CL. 
What a disappointment. 
I was disappointed by older VM 15mm II mounted on M6. 
I guessed that V3 is not good enough for me too. 
Last time I bought a Voigtländer. Leica and Sigma are way better.

All three profiles for the WATE are identical. As the lens has no frameline coupling -obviously- Leica decided to use a compromise profile for all three focal lenghts. The manual setting will only affect EXIF.

After testing, I found that 16mm WATE can be okay. Actually it does not do much. 

But best results are with Lightroom profile for VM 15mm III with vignetting correction OFF (slider to minimum) and chromatic aberration ON

I prefer the latter, because it will not confuse me later, when using a real WATE in the future.

Lightroom profile for VM 15mm III is weird. I think that it does not account that CL is an APS-C sensor ! 
Vignetting correction is way too strong. I just turn it off. And it is fine. 
Chromatic aberration is not an issue with correction turn on. 
I have to check if distortion correction is correct or not. It is indeed corrected differently when set with WATE at 16mm profile. 
 

Some more tests to be sure of the right correction.
