    I'm not a dentist, but I guess I could marry one! That it'll be the only way I can get a Lecia.

    A practical question: in the real world how usable is a lens at f/0.95? The DOF would be extremely shallow (I checked DOFMaster, but it currently only goes down to f/1, which is still pretty shallow - a 50mm lens on an M8 calculates as 0.55 ft. of total DOF at f/1).
    i can't wait to take a picture of my thumb with this beautiful camera.

    Well, for David Hamilton style it would be usable

    Practical enough for Leitz to rationalize making them. At 6 grand a pop they're not going to make that many but I bet they sell all they make.
    People use Holgas don't they?

    If it were longer I'd mount it on my spy plane and shoot IR.... Rerun your dof calcs at long subject distances

    For astro it might also be fun.

    But of course just because it is f/0.95 doesn't mean you have to shoot it wide open. Especially if you are composing ttl on an slr then it'd be very nice for low light work; the viewfinder would be very bright. I use a Nikon f/1.2 quite often at night; rarely do I actually shoot it wide open, but I sure like the viewfinder brightness! Especially since it is a manual focus lens....

    Anyway, I think what is very special about this lens, as compared to the Canon, is the extensive use of aspherics.

    Other makers produced quite fast lenses for Leica and other cameras. Zunow made a 50mm f/1.1, perhaps in the 1960s. I saw one in a PX in Yokosuka, Japan, on sale for $5. Long ago Leica made one faster lens than the new Noctilux, the 1934 Summar 75mm f/.85. It was not intended for normal camera use. In those days before lens coatings it would have lost quite a bit of light due to reflections. Other special purpose lenses are sometimes quite fast. I have a Canon 90mm f/1 that is probably a projection lens. It won't cover more than a fraction of a full 35mm frame.

    Is it a coincidence or does the Leica M8 with the new Noctilux look very much like a Panasonic Camera?

    Cheers!

    That's a very good point - didn't think of that (but is that applicable on a rangefinder - or M8, not sure if has an actual VF or if it's an EVF). Not sure it's worth ~$6k for a brighter viewfinder, but an interesting point none the less.
