A 40mm f/0.85 for Your EOS-M?

I had a look. Yeah, the images really don't look like they're worth $2000. I'd almost say the 50 1.8 would do an equivalent job. The way the out-of-focus specular highlights render is really annoying (e.g., xmas tree pic on that site).
pass.

Basically you are right, it will be a few people.
But if that lens allows a new perspective/way of expression ... why not? I mount a 1400 Euro lens on a 350 Euro camera (EF 5.6 400 on 600D) which allow to do some tele photography / video (landscape/nature, where the 7D AF system is not necessary).
Think about video in low light in tight environments ...
Not that I am interested to much in that lens - if I use a high aperture lens I would like to have a great AF and perhaps IS to extend the range of use into near darkness.

Looks like a perfect match for the Hasselblad Lunar. A couple of thousand is pocket change for those people, they probably have a camera caddy to carry it for them anyway, so weight isn’t an issue either. All they have to do is add a wooden focus ring and at least triple the price.

That camera is crap for the price, like all of the Panasonic 'Leica's'. I can't believe people with big wallets are so easily misled.

I also wrote an article about fast lenses about two weeks ago. Maybe I should update it with this Germanese lens?

Yeah i'm leaning towards not-acceptable. The effect is neat on the xmas tree but it doesn't give the separation that you'd normally want from a fast lens. I suppose it'll be good to see some full resolution crops too - hard to tell how bad the CAs are on those images. If it has stellar loca performance then it might find a niche.

Thank you for this interesting link. The champion is the Zeiss 40mm F0.33, but this one is not useable for photograhpy.
The late Lex Werkheim told us the fastest lens possible would theoretically be a F0.5, but he did not tell us how this was calculated.
Anyway, I think 0.85 is already too fast to be useable in real life photography, except possibly aerial photography (over a flat coutryside) or x-ray photograhy. The only advantage of such speed that I see is that it makes focusing easier in the dark.
Kind regards,
Rob.

The images aren't terrible, and the color looks interesting...but I agree, the bokeh has a very strong ring around highlights. For such a shallow DOF lens, everything that is light in a shot is going to have a ring around it.
I wonder if the medium focal lengths such as 40mm to 100mm can be designed with an aperture this fast, and not have strong rings around bokeh highlights? If so, how would it be done?

I do aerial photography, and I can't imagine ever needing such a fast aperture. Of course what I do is in daytime. It would be useful for night or low light aerial photography (or perhaps during very dark, severe storms...assuming you're crazy enough to fly in them!).
Interesting tidbits about the Zeiss and the fast aperture theory. Zeiss also made a 90mm f/.9 or something, didn't they?
I for one, would like a 30-120 zoom with constant f/0.9, autofocus, and image stabilization...with bokeh as smooth as Canon's 135 f/2! Would that be possible? The front element would be 130mm or so, and it would be heavy...but surely it's not physically impossible...
