    I've blown my gear budget for the year otherwise I'd be all over this. I would love this on my Kiev 60. Denys, I'll keep an eye out on your progress. Coating isn't a concern for me.

    Medium format Petzval portrait lens. Petzvar f/3.8 120mm

    If you could create a petzval that worked for 4x5 AND had a shutter, this would be of much more interest to me sadly.

    Actually, the Mamiya RZ's lens shutter works independently from the other electronics, it's possible you could set a simple function to simply trip the mirror lock up, and leave the rest of the functions to the lens as normal, if it had it's own shutter.

    (And the Hassleblad C's as well)

    Interesting project. I don't know if you have the optical design locked in, but the swirl seems excessive to me. The best properties of the Petzval have nothing to do with swirl--which is a one-trick pony. In any case good luck with your kickstarter, I think it's great that people are reproducing a classic lens design that still has a place in photography.

    Yes, technically it is not very difficult to calculate the lens that will work with Mamiya RZ or 4x5 cameras, but building the prototype is really expensive. And the only thing that can compensate for expenses is the volume of production. Especially when it involves fairly complicated shutters.
    I seriously doubt that the effort will be paid off.

    Thank you for your comment. I know exactly what you mean, but the lens is just an instrument and can be used in different ways by different photographers. Those sample shots were taken to show the lens' ability to produce a "signature" swirls, but it is very easy to take a pictures without it, by using a smaller apertures, or placing the subject at different distances,or simply by cropping the final image. Using a smaller sensor cameras will cut the swirls off too. I'm sure you know what I mean - it is not always easy to get those swirls from the Petzval, but you can, if you want to.

    this looks great - if you ever decide to make one for the Mamiya RB series let me know!

    Thanks! Sure, I will. But it won't be soon. Currently I'm working on lens with Hasselblad " V " mount for 2000 or 200 series.

    Is anyone else having problems with Kickstarter on this project? I've tried to participate and Kickstarter has been a "no starter" for me. Bill Barber

    I'm only vaguely interested because of the mount.
    If I had a system with the mount I'd be very interested.
    I wouldn't buy into a new system because of the lens.

    I would be very interested in Petzval cells that could mount into a modern LF style shutter, even a Copal 3 or 3s.
    I would also be very interested in something for the RB67 system which I have, which is cheap, and which can easily be hacked into a lensboard if you want to use it on something else.
    I might even be interested in a 'blad 500 lens.

    Just my two bits. It's not like I'm making the thing. Maybe one day....
