For those who are still on debating how big this beast is... can judge for yourself...

It's around the same size as my Noct E58, i have compared it side by side, both without hood. Wish it helps. :>

Hmm people don't read posts do they?
I've already stated that it's likely due to the use of high refractive index glass that we're seeing larger DOF but a measured t-stop (light gathering ability) about 2/3 stop faster than 1.4 or equivalent to f/1.1. I have a leica f/1.4 50 on my slr and at iso 400 it meters about 2/3 stop slower than the nokton wide open with 400 ASA superia.

fwiw the pupil is definitely larger than that of the canon 50mm f/1.2 LTM. it looks to be between 43 and 44mm across. assuming they're not rounding down the focal length, that would put make the physical aperture between 1.1 or closer to f1.2.
i finally got around to develop some rolls. here is one on astia

The best camera is one that still works!
This image was on the mainline photo blog here in oz ... I hope no one minds me reproducing it here but shows some intersting aspects of the lens!

I know I read them, but your earlier supposition that the lens had an F-stop of 1.2 but a T-stop of 1.1 didn't really seem reasonable to me. You are suggesting that the lens transmits more light than it gathers. Maybe I missed something regarding the new coatings?
BTW, the DOF of the lens doesn't bother me at all - I would not say that it looks too large to be an F1.1.

You're quite correct, perhaps the t/stop and f/stop are close to f/1.1 but the f/stop of faster (or equivalently fast) lenses is actually higher and the t/stop is equivalent to the nokton.
So at f/1.1 the nokton may have t/1.1 and the noctilux at f/1.2 may actually be f/1.1 but have t/1.2.
However, I suppose someone with a digital body has to do more testing, I'm not going to waste film I could be using to take pictures
I hope mine never does that, I really hate colour shift in OOF highlights. It seems to affect digital much more than film though.
Love that shot on Astia 0bli0, I just ordered a bunch of pro400H, provia 400X and Sensia 100 to play with
This lens has added fuel to the fire for shooting film, it's just so versatile.

Hi - thanks for the welcome
No problem at all with you posting the link.My, my - this lens seems the hot topic in the Voigtlander world at the moment eh !
I actually ordered an ND with some coloured filters today, so I can open up wide during the day too. Intending to take a load of pics at F/1.1 so I can get used to the lens performance there.
Unless of course someone wants to donate me an M8.2, so I don't have to waste film !!!!

Well got my lens last week and promptly took it out for a spin. Even though there are tons of photos posted, I was still curious to see how the oof areas would look on my shots. I wish the lens focussed another foot closer but I can live with it
Here are a couple of scans. MP and Tri X. The last two are basically at minimum focus. All wide open.

ps-can't remember how to post photos so they show up automatically...help
just click on that orange and green button - just above this box where you type text. it will open a window and you put a link to photo in it...
>So at f/1.1 the nokton may have t/1.1 and the noctilux at f/1.2 may actually be f/1.1
>but have t/1.2.
According to the 1976 pop Photo tests, the F1.2 Noctilux is T1.3. The lens tested was not multicoated. The Nikkor 55/1.2 was a T1.25 lens, was multicoated. I'll double check when I get home.

Looked it up in the May 1976 issue of Pop Photo.
Noctilux 50mm F1.2 lens: measured f-Stop of F1.20 and T-Stop of F1.30. Transmittance is 86%.
The Multi-coated Nikkor 55/1.2 measures F1.20 and has a transmittance of 93.3%, T1.25.
The Zuiko (Olympus) 55/1.2 had a measured F-Stop of F1.31, T1.42, and transmittance of 84.25%.
Not all F1.2 lenses are equal.

i hope people now see that shallow DOF on last 2 photos...

Here's a ton of shots, some ok, most not so great All on superia 400, I've destroyed 2 rolls over the past 4 days so I've lost a lot of shots, thankfully all cheap film and all just more happysnaps like these. Hope people can gather something from them, all at f/1.1 except last two at f/8. I recommend the hood if you're in contrasty lighting and shooting wide open, I've lost a couple of shots from incident light.
this one might have been at f/2.8?
These two are the f/8 images:

To the owners: I'm curious how much does the 1m minimum focusing distance really bother you? Ideally I would like it to focus closer too, but I'm not sure if it's really that big of a factor.

For me it's not a deal breaker but it could be quite useful although I have no issues with cropping an image if it needs it. I've thought of playing with close up filters and mentally noting parallax movement but it sounds like too much bother really.
The only reason I got the Nokton was for the low light opportunities it allows.
