It would be great indeed if Cosina also makes a Micro 4/3 digital camera later on 
With the announcement of the new Voigtlander 25mm f/0.95, the price of the Angenieux and Schneider 25mm f/0.95 lenses will certainly go down to a more affordable price...

I think it's great the Mr. K is finally making products explicitly for the digital market. I'll probably end up finding a way to buy a copy of this lens--it is the exact thing I've been asking for since I got into the m4/3 system.
If you haven't focused a fast manual focus prime on m4/3, especially using a high-resolution EVF, you would be really, really surprised at how simple it is to get tremendous precision very quickly. People will have no problem at all focusing this thing.

No. The sensor is 1/4 of the size, so the "light gathering power" equivalent is 50/1.9.The 25/0.95 is the equivalent magnification and light gathering power of a 50/0.95 on the 35mm full-frame.
25/0.95 = 26.3
50/1.9 = 26.3

Actually the light gathering power is still equivalent to an aperture of f/0.95, with the depth of field on the Micro 4/3 camera's digital sensor output images being equivalent to the same depth of field of an aperture f/1.9 on a full frame digital or 35mm format

yeah i heard that if you take 1500 pictures of your cat or back yard you it can cause your a++ pro lens skills to level up to +10 acp/UISD firmware and then you can get protip maneuver skills with those hubcap junction photos you posted last thursday.
Lay off the grog. What's this hubcap junction you speak of? It sounds interesting.

OK here is a crazy thought.
Maybe, just maybe, Mr. K is secretly working on a Micro 4/3 body WITHOUT auto focusing mechanism. And the saved space will be used to put RF instead of EVF. The whole think can be similar or even smaller than Leica CL or current digital PEN series. Well, regular m4/3 lenses don't have RF coupling so I guess EVF is needed...
And by the time this camera gets the market, CV (and possibly Zeiss) would have several prime lenses for the system.
Now that's the digital camera I can get super excited about.![]()
I hope no! I don't want to buy a whole set of new lenses together with a new camera...
If this would be the case I'd probably really start saving for a Leica M9.
Did someone hack into Cameraquest's account? What a weird topic...

An f/x aperture is an f/x aperture in terms of speed anywhere. At the same ISO setting and shutter speed, it will render equally bright images for any given focal length on any given format.

And it's in a wrong section too - shouldnt this be in either RFF polls, or Micro 4/3 section?

Obviously you didn't read the link. Light per area is irrelevant if area is excluded. ISO 100 isn't equal on every format. Larger area = more information = less grain or noise. So, ISO 100 on MFT is equal to ISO 400 on FF.An f/x aperture is an f/x aperture in terms of speed anywhere. At the same ISO setting and shutter speed, it will render equally bright images for any given focal length on any given format.
Again, the 25/0.95 on MFT has equal light gathering properties as a 50/1.9 on FF.

No, an f.95 lens on an e-pl1 @ f.95, ISO 400 yielding a shutter speed of 1/30th will give the same exposure as a f.95 lens @ f.95, ISO 400, shutter at 1/30th on an m9.
Regardless of sensor size, lens speed is the same. The depth of field is different at equivalent focal lengths between formats, but an f.95 lens is an f.95 lens on a point and shoot, or a DSLR, or a hasselblad H3D.

Either the link is wrong, or you're interpreting it wrong. I know, because I've used an e-p1 and a full frame 5d back to back on working assignments, and both will take an equal exposure at any equal iso using the same shutter speed and aperture settings.

Yes, but nothing even close to an equivalent image in terms of quality. Exposure is irrelevant.No, an f.95 lens on an e-pl1 @ f.95, ISO 400 yielding a shutter speed of 1/30th will give the same exposure as a f.95 lens @ f.95, ISO 400, shutter at 1/30th on an m9.
And "f" is different, so "f/0.95" is also different. This is just as silly every time people without the slightest technical knowledge are trying to convince us that the laws of physics are wrong.Regardless of sensor size, lens speed is the same. The depth of field is different at equivalent focal lengths between formats, but an f.95 lens is an f.95 lens on a point and shoot, or a DSLR, or a hasselblad H3D.
Buy a point-and-shoot then for heavens sake.
Why are you talking about exposure? This is about light gathering, which gives image quality. Don't try to say that your EP-1 gives the same noise at ISO 400 as your 5D does.Either the link is wrong, or you're interpreting it wrong. I know, because I've used an e-p1 and a full frame 5d back to back on working assignments, and both will take an equal exposure at any equal iso using the same shutter speed and aperture settings.

I could care less if this lens is real or not, if it is, I can't see it selling well at all. Most people with Micro 4/3 don't want to manually focus a lens, and trying to manually focus this lens wide open would be a chore. It doesn't make sense to me to make an exclusively manual focus lens for a autofocus system when there's not a good manual focus method in place
I would say most f/0.95 lenses are specialty lenses and are more labors of love than a get rich quick scheme. It is clear to me that CV is in this for the love as well as to make a little cash. Also, do not under-estimate the Japanese market and what they want... if you go to a site like this, you will see the weirdest combos...
