Thanks for these. Looks like the Septon will be nice sans grip. Get mine in a few days. I really enjoy the 1.2, so the debate on whether to keep both will happen soon.

Thank you Yes the portrait is at F2.0, (ISO400)
Oh my.
SOOC rendering looks very good. Like really good.
I am strong.
I do not need a 40.
40 is still too tight for what I need.
There is no such thing as "the one lens"
40 shoots too much like the 50s on the shelf
Too many lenses - don't need another.
This is available now, don't wait for the 35/1.4
Am I a photographer or a lens collector?
I could sell all the rest.
It is still too tight.

Whew. Got that out of my system. (Please do not post any more samples. thank you!)

All true… but the 40mm is sneaky because it can replace both the 35 and 50 when you only want to carry one lens.
Sorry, I may have made your "I do not need a 40" speech much harder to maintain.
Not really a choice. It's tight in my downtown location and 28 is best, with anything longer often being work to unjam. 35 works like 50 used to and 50 works like 85. In midtown or parks, etc, 35 is ok, 40 probably. But, most working distances are pretty tight.
Second reason is shooting zone; 35 is my comfortable max. for zone. With the 40, you lose a stop to DOF viz the 35 (with 12' focal point) - i.e. 40 DOF at f/11 is about what f/8 is on a 35.
So, for my pretty narrow use, chipped lenses for the Zf (instant-condition-with-dials) and MF (zone for quick, close, chaotic shooting), 28 is best and 35 might work.
I'd jump on the Septon, otherwise. The good news is that this 35/1.4 on the other thread looks reminiscent of a steel-rim Summilux and that has its own charms.

Yes, it does help block stray light. The hood reduces the effective opening from 52mm down to roughly 37-39mm, which reduces the light gathering area by about 45-50%. This makes it significantly harder for off-axis light from the sides to reach the front element and introduce flare. It's not as effective as a properly sized, deeper hood designed for the 52mm thread, but it's still better than no hood at all, especially considering Juha's point about the added protection.
Voigtlander likely designed the hood to prevent vignetting when a filter is screwed onto the lens, which also translates into better protection against flare. I wonder if, with such short hood (original), adding a filter wouldn't introduce new reflections into the lens? And secondly, wouldn't it be better to just screw in the lens 52mm filter ring (without the glass) for better flare protection?

I think they had already been planning that as they seemed positive about the idea already then, but can't be sure about the follow-up before they announce something. I hope they don't get any wild ideas about making it a different focal length like 25mm instead I also wonder if they could make it a little brighter than f2.8 while keeping the same size (f2.4 or something).
would 28mm f2 Septon be that bigger?
and next 75mm f2 Septon - to to make the whole set similar.

I would be interested to hear Juha's thoughts on this, but based on the optical designs Cosina used for their Fuji X-mount lenses, there may be some clues. Their 40mm and 28mm full-frame equivalent lenses (27mm and 18mm on APS-C) share essentially the same compact size, yet the 27mm (40mm equiv.) is an f/2 design, similar to the Septon, while the wider 18mm (28mm equivalent) is limited to f/2.8 rather than f/2.
Subject isolation on this is insane. F2 seems to be a good sweet spot where for a somewhat loose framing, you might not get as much blur as the 40 1.2, but you have enough of the subject in focus where they really separate from the background (avoiding controversial buzz word here lol).

LIke Fred also noted, previously Cosina has tried to keep the sizes very similar between their 40mm pancakes and 28mm the counterparts. That was the case with their X-mount APS-C 27/2 and 18/2.8 and I think the same also applied to their SLR lenses where the 40mm was always f2 and 28mm was always f2.8.
I believe they would also want to keep the size of a potential 28mm pancake counterpart of Septon 40/2 exactly same or very close, and that might require them to make it slower based on those other examples. I hope they could make it a little faster than f2.8 but I think f2.0 might be too difficult without making it obviously longer and no longer classifiable as a "pancake".
There are also already the 28/1.5 and 28/2 options from Cosina for FF mirrorless so making something quite close to those in size to reach f2 wouldn't make as much sense. I think a 75/2 would also not be possible in pancake size.
Anyway, I'm not an optical designer and I'm not fully sure what they could achieve these days especially at 28mm.. We'll have to wait and see what they come up with later

So how did it end?
I'm still debating which one to buy for Z.. especially for landscapes. Have you compared both side-by-side at f5.6 to f11? Both have field curvature, but which one is less annoying? Is one significantly sharper at these f-stops, including the corners and has also more purple fringing? These are questions I haven't found the answers to yet.

I can post the originals if you want, but to me it's clear that the Septon is sharper, even as the accesory lens is made for the Ultron.
Thanks Jasper.
If you have both could you shot & post same far distance scenes with f/8-11 + central and corner crops? I would love to see such "landscape" comparison.
I want to add a 40mm voigtlander back to the kit to compliment the 28 nokton..I owned the 40 nokton back in the day, but the size of the septon is super appealing. That said, I have the TTA 40 F2 already, and I'm pretty happy with that as the compact P&S type option when I want to go compact.

Please could you post some more comparisons of the ultron and septon at medium and infinity distance stopped down to f4 and f8? which version of the ultron do you have?
Yes the portrait is at F2.0, (ISO400)
