p.6 #1Cosina Voigtländer Nokton Vintage Line 28/1.5 VM lenses announced today
The preproduction sample of the CV 28/1.5 Type I is expected to arrive tomorrow, courtesy of Voigtlander for an introductory look. My assessment will focus on ergonomics, feel, focusing, etc., as they are still refining the optical formula for the final production model. I'll capture some initial impression photos with it, but I plan to reserve in-depth lens testing for the actual production lens later on..

p.6 #2Cosina Voigtländer Nokton Vintage Line 28/1.5 VM lenses announced today
Update: I got the lens just an hour ago. It's quite small for a fast 28mm lens, especially when compared to the Leica 28/1.4 Lux. As mentioned earlier, this is a pre-production version (Type I aluminum), and I already know that it's very slightly front-focusing. Tomorrow, I'll kick off the review thread, share some lens pictures, and give it a test run to assess its rendering. I'm prepared to mention that while there's some vignetting, the specular highlights stay round towards the edges. It's more like a tic-tac than a cat's eye.

As per our discussion, I won't publish any resolution, contrast, or optical test shots until the production copy arrives. However, between us, the CV 28/1.5 Nokton excels in resolution/contrast and has pleasant rendering.
I just examined my infinity test, and I'm highly impressed. It performs well even at f/1.5 and hits its peak at f/2.8. The corners are exceptionally sharp, and there's no significant resolution drop at mid-field. I can already foresee that this lens will be a top seller for Cosina, performing like the Voigtlander 28/2 Ultron and 28/2.8 Color-Skopar, but it's an f/1.5! There's some lateral and axial chromatic aberration, but it's well controlled, especially when compared to the Leica 28/1.4 Lux.
So far, no negatives to mention. I believe Cosina won't make any optical alterations; it's a definite winner so far.

Hi Daniel,
As you close the aperture, diffraction becomes more noticeable, especially with higher resolution cameras like the M10-R 40MP. The increase in resolution can make diffraction more apparent, but it's important to note that diffraction itself doesn't change. At the pixel level (100% magnification), I notice some softening at f/8 when using the M10-R.

I changed my plan to hold off and preordered one just now (Black Type I). I hope this will be play well with Sony sensors (I'm quite happy with the 28/2.8). If not I could always trade it in later...
Should hopefully receive it on 19th

Hi Fred, will you be able to test the lens on a FF Sony body? I don't expect it will be great in the corners WO given how wide it is and optimized for Leica, but if it cleans up by 2.8 or even F4 it might be worth considering.
Thanks
Mike

It seems to be the Vintage Line default. 75/1.5 is the only one in current Vintage Line without this type of shiny front ring but the recent releases in other lines have avoided it.
I'll use mine with the hood (I always do) so the shiny ring doesn't interfere.

And still the rest sounds more than promising. I will definitely add one to my line up. The type II looks nice to me, even with the silver ring (that I will never see with a lens hood).
By the way, @BastianK, any new impressions with the Thypochs? Do you like the rendering so far?

That is not necessarily true, as that silver ring remains inside the lens hood and can still lead to unwanted artefacts.
The two Thypoch lenses have the same issue.

I will publish an article on 18th covering my first impressions of both lenses.
I like the bokeh, I am having a look at resolution/contrast today, but the handling leaves a lot to be desired.
It is nowhere close to the Voigtländer lenses, I think it is actually way worse than what we usually see from TTArtisan/7Artisans.

I have seen some flare artifacts from the shiny ring but very rarely when using the hood with my other CV lenses so I don't think it's a big problem when hood is used, and it can be seen on EVF before taking the shot if anything unexpected is going on when shooting with mirrorless cameras. It could be more of an issue with rangefinder cameras.
Would be better without the shiny ring but for my own use it's not a big issue.

Hopefully you can do a comparison between the CV 28/2 and 28/2.8. I really like the small size of these 2 lenses, I am not sure if f1.5 is something I really need in a 28.

I was considering comparing it to the Leica 28/1.4 Lux, Leica 28/2 Cron, and Voigtlander 28/2.8. The 28/2 Cron and CV 28/2.8 show similar performance to the CV 28/2 Ultron, but I'll check if I can borrow one to test it out.

I don't suppose there's any detente or similar function at the 0.7m to let you know you've lost coupling like on a Leica close focus lens, is there? Or does it do the (frustrating to me) thing where it just stops moving the rangefinder patch, making the RF impossible to use at close distances.

Similar to other Voigtlander lenses, there's no tactile feedback when focusing beyond ~0.7m. In a quiet environment, if you pay close attention, you might notice a slight tactile sensation when the RF roller disengages.
The positive aspect is that, with the RF (starting with the M10), most M lenses can focus quite close, down to around 0.6m.

Whether that filter spacer will work for many people will be determined by whether you can use it with the hood. I know my Voigtlander CVM 28 f/2 II does not allow use of a filter and the hood, which I see as a major flaw (but one shared with almost all Leica M mount lenses). Personally, I would rather go with the hood and no filter spacer than the filter spacer and no hood.
