Image circle and flange distance are different. Nothing to be surprised about. Equivalent 35mm AF lenses sell for much less than this, not to forget that they are optically far superior.

Nobody was too excited, eh?
Some are excited ...

I am curious more than excited ... at least Steve Huff has a lot of reference lenses to compare with and knows his stuff.
Interesting note from the comments :
"Indeed, it is probably just re-branded and fitted with an MFT mount. But from what I could gather from forums and flicker albums, with 50mm TV lenses the image circle is large enough for the MFT format there are even some good 25s that wont vignette."

e.g. EF 100mm F/2
Those sample photos on flickr from this 50/0.95 look mushy at web size... sigh

Steve Huff posted his first look review of this lens. I personally thought the pictures looks excellent, I like the feel. 2 pics linked from his website.

I can think of a million uses for this lens for video work on the m4/3 cameras... image wise, it is quite unique in the way it renders colors... but to spend USD750 for this lens might be a little erm... There are much option in this price point... though the f0.95 is somewhat a draw. Not a lens for everyone.

Right on, not a lens for everyone. IMHO, forget the colors from the samples, Steve is no copy machine (read that somewhere
), he processes his images, in this case cross-processed, etc.But the softness is unmistakable, just like some old Leicas, and bokeh character. Once again, either one likes it or not. There are still debates in the Leica world regarding pre-ASPH (old) and ASPH (new), so it really is subjective, no right or wrong.
But price ... maybe hunting down the original lens and using an adapter will be cheaper, for those who want one. Then again, price is relative, probably cheap for Leica users who use m4/3 as well but don't want to put a $10k Noctilux on an E-P2.

This should be the lens. Do take note of the flange depth, may not be suitable for some c-mount adapters. The ms optical one should be able to clear, just send them the dimensions to confirm before buying. They are also branded as Senko and Navitron.

Yup probably forex comes into play here yen vs US$. They just probably modified the mount, if you find pics of the lens. The c-mount is easily removed by the hex screw at the side.

The lens look too much like cctv lens but the photos from the lens doesn't have vignette :dunno:
Isn't that a good thing?
yup.. that's what i think so. but if people suspect it is a cine lens, it shld show vignette? Or the manufacturer of c mount-m4/3 can remove the vignette from c lens? :dunno:

As mentioned above,

normally the 2" or above focal length CCTV/Cine lenses wont vignette on m4/3
- 50mm & above =>no vignette
- 25mm => slight vignette, some wont vignette
- 12mm-16mm => severe vignette
- 10mm & below => looking thru peep hole

The lens diameter looks a lot larger then the 'TV' lens, so I would imagine it should have a larger image circle. I'm using a C-mount .95 25mm lens on my GF1, it's on the lens 80% of the time now. The bokeh is quite good. I wonder if anyone had done a comparison of what is the equivalent DOF equivalent of FF (35mm) with a .95 on m43 sensors. Does that equate to f1.2/1.4 on FF ? From the pict, it sure feels like it's close to 1.2 on FF.
I'm tempted with this actually. And would be great if they come up with a EF mount for my 5D2.

I am curious as an noob.
For a f0.95 lens, physically the aperture is at f0.95, even if the sensor is half the size of FF (such as 4/3 or m43 sensor), why would the f0.95 suddenly become larger (or smaller aperture)? I mean, physically the aperture size would not change right? What am I missing here?
