Yeah, but 35/2 and 40/1.4 are already well covered and fit on m43 via simple adapters. they should make 17mm f0.95 and 12mm f1.4. that will be a big void for them to sell to. I would buy these as I already have the teles well covered.It is great that CV are producing m4/3rds - may be they'll do a 35/2 or 40/1.4.

Hi Jerry, the reason its impossibe to focus manually with lenses faster than f2.8 on canon 5d2 is because the size of the mirror limits the accuracy to f2.8 only. meaning if you use f1.4 lens, what you see in the viewfinder is the dof at f2.8.I tried to focus manually with 5D II, I even bought dedicated brightscreen. And quickly quit.
It doesn't compare to "M" rangefinder or u43 manual focusing, in my opinion.
I would gladly take a 17/1.2 and a 12/1.4, provided they are appropriately sized for a manual focus lens for the "micro"4/3rds.they should make 17mm f0.95 and 12mm f1.4. that will be a big void for them to sell to. I would buy these as I already have the teles well covered.
I think that we are witnessing, from Amin's samples, another shortcoming of the small 4/3-m4/3 sensor in that wide focal length lenses inherently have greater depth of field, so using a 25mm to achieve the 50mm equivelent is not going to yield narrow DOF anything like a 50mm on a full frame sensor, even given the same true aperture values used in both instances. My other gripe with 4/3 size sensors is the inherent distortions from wide angle lenses, for example using 35mm lenses for a short telephoto equivalency of 70mm as a close-up poirtrait lens will completely distort a persons facial features. Indeed, if I could afford to buy a Leica M9 and lenses I'd never use another 4/3-m4/3 body again. So really impoverishment is the only reason that I even suffer these malodies. Thanks for the great samples and link to samples for this lens.The boket looks jittery/nervous.
Anyone has checked to see if this is indeed an f/0.95 lens? I ask because, I have a few "f/0.95" lenses that appear to be at best f/1.1 or so.
Coors, this part of what you said is not correct. If you keep the same subject distance, a 35mm lens on 4/3 will give the same framing and perspective (no difference in distortion of a person's facial features) compared to a 70mm lens on 35mm format. Example: http://www.seriouscompacts.com/f41/bokeh-test-olympus-zd-25mm-f-2-8-vs-canon-ef-50mm-f-1-4-a-161/My other gripe with 4/3 size sensors is the inherent distortions from wide angle lenses, for example using 35mm lenses for a short telephoto equivalency of 70mm as a close-up poirtrait lens will completely distort a persons facial features.
. . . . . disagree with your comments, I can not find anything I dislike with the samples Amin provided, rather nice shots IMHO. The images that have been displayed throughout the multiple threads on this forum and others have certainly provided plenty of proof that m4/3 & 4/3 camera and lens are a capable tool and produces high quality output.I think that we are witnessing, from Amin's samples, another shortcoming of the small 4/3-m4/3 sensor in that wide focal length lenses inherently have greater depth of field, so using a 25mm to achieve the 50mm equivelent is not going to yield narrow DOF anything like a 50mm on a full frame sensor, even given the same true aperture values used in both instances.

Then - you will have different focal, won't you?So I might rather use my Noctilux 1.0 with adapter - I think the much better solution WRT IQ!
This is a, to me, very strange comment. You are technically wrong with regards to what you say about equivalent lenses. And, distortion (of facial features) is depending on the shooting distance only (assuming the lenses are corrected).I think that we are witnessing, from Amin's samples, another shortcoming of the small 4/3-m4/3 sensor in that wide focal length lenses inherently have greater depth of field, so using a 25mm to achieve the 50mm equivelent is not going to yield narrow DOF anything like a 50mm on a full frame sensor, even given the same true aperture values used in both instances.

Thank you Amin. I try to interpret the bright parts in the background. They aren't specular highlights so it makes it harder to see the differences between the aperture openings. I think f/1.4 looks good (to me). Maybe there is some coma, maybe it's visible only when having highlights in the background.(...)
Here are a few more bokeh samples of the Nokton for anyone interested. The f/0.95 and f/1.2 shots were blown out at 1/4000s and base ISO, so they don't put the lens in a very good light (pun unintended):
How do you know the contrast is "low" wide open? Does the Noctilux 1.0 have high contrast wide open? And since when can a 25mm lens be replaced with a 50mm lens?Well, it shows very low contrast wide open. Which is what I do not like.
So I might rather use my Noctilux 1.0 with adapter - I think the much better solution WRT IQ!
Just look at the samples with different f stops and you see. What I normally get from Nocti is almost full contrast wide open - just one of the strengths of these high speed Leica optics wide open.How do you know the contrast is "low" wide open?

Ah, maybe all the questions are rhetoric ones.
Sure you have and this is more than welcome!Then - you will have different focal, won't you?
But hey, Amin said the two first images were overexposed... I don't expect full contrast from them. And why is it I have seen so many greyish Nocti images? But, I haven't owned, or even used the Noctilux so I really don't know.Just look at the samples with different f stops and you see.

WRT 25mm - sure this is not 50mm, but I used the 1.4/25 on my E3 and I never was happy with the look it produced - you could see it is a WA lens. What should be different for the Nocton 25 ???? Sure it is nominal 50mm but it is no real 50mm lens at all. And I would anyway prefer more the 50mm (100mm on FT) for available light shooting, especially of people.
Of course compared to the price of the 1.0 Nocti this lens is a bargain. But it does not rock me - understand what I mean?
Why we compare 25mm f/0.95 to FF Noctilux? It doesn't make sense to me... If at all - then to 50mm f/2!so many greyish Nocti images

a) only because ptomsu mentioned he likes it, with regards to optical quality, better than the CV25/0.95. Then he also said 25mm is too short so he generated a short discussion, sort of.Why we compare 25mm f/0.95 to FF Noctilux? It doesn't make sense to me... If at all - then to 50mm f/2!
Noctilux on FF gives to little DOF for every day applications.
It was useful in past, for bad light. Today - it is admired just by PAPER DOF onanists.
I saw many pictures with it and most seemed useless for me. I see no context at all. This is fine, but for limited usage, for some group of people.
If someone wants to achieve the same in u43 - better is to use longer lens with not extreme like 0.95, but more like 1.4 or 2.
Counterpart of 50mm f/2 on FF has still every day usage.
A 1.5 or 2-stop ND would do the trick there.The f/0.95 and f/1.2 shots were blown out at 1/4000s and base ISO, so they don't put the lens in a very good light (pun unintended):
Thanks Peter for your Kind words . . . . .Dan your shots are fabulous.
And I really love the way this wonderful lens renders OOF.
Keep posting!
