If anybody knows who is in change of this kick stater project can you please let him/her know that it is "Petzval" NOT Petzvar. I can see one or two spelling mistakes but when it's constant it makes me wonder if this is a true campaign. The same goes for "Fine art lens" A lens is a lens
Bill, I'm so glad to hear that!I have mine in my hot little (actually big) hands. I've ordered an Arax 60 would should be here in a couple of weeks. Will post results when there are some. Bill "Happy Camper" Barber
Thank you for your thorough explanation. I always thought it's obvious that the lens supposed to have its own name. Until people start to point at my "misspelling"."Petzvar" is his brand name for the lens he's making, like Sonnar, Planar, Heliar, Distagon, Dagor, etc. Dagor, for example, stands for "Double Anastigmat GOeRz". So calling this particular lens a Petzvar is just a clever way of letting the buying public know that it is a Petzval-type lens.

THAT is a thoroughly different lens on CameraQuest. That is the Lomo "Petzval" which is in actual fact a re-bodied FSU Zenit Helios that is not a true Petzval lens, and only mounts on Canon or Nikon 35mm/FF DSLR bodies. The Lomo "Petzval" will swirl at large apertures, but it's not the same as a true Petzval because it swirls for very different reasons. The true Petzval swirl occurs because the lens does not focus on a flat plane, but rather a curved field of focus. The true Petzval produces soft-focus effects in its out of focus areas because of lack of chromatic aberration control. A Zenit Helios will produce razor sharp images at the plane of focus even when focused close and wide open.
The Petzvar 120 mm f= 1:3.8 portrait lens is not a re-designed or improved model, it is a genuine Petzval with all of its inherent flaws and imperfections.
Original lenses of this design were produced over a hundred years ago for use on the large format cameras of that era. Those swirly bokeh and the focus fall off in the off-center areas, caused by uncorrected astigmatism and chromatic aberrations were a big problem of the design. Therefore, larger coverage lenses were designated to smaller format cameras in order to crop out the imperfections at the edge of the image circle and leave only the sharpest center part of the image in the frame. For instance, a lens capable of covering an 8x10 inches plate, would be used with a 4x5 camera.
By today's standards, this primitive design can't compete or be compared with modern lenses in any respect, it has lots of known optical flaws, corrected in contemporary lens schemes. But those imperfections are the exact reason this lens became so popular among analogue photographers.
(...) all of P6 mount lenses have been shipped to Kickstarter backers. Many of them already delivered, according to the tracking information.
Hasselblad mount lenses are still waiting for mount parts. They are already assembled and the only reason for delay is those mount parts. Manufacturer's mistake have been corrected and mount parts will be re-made within few days. (...)
Here it is, Bert, taken by my wife yesterday with Petzvar mounted on Kiev 88CM. Scanned with my old Epson scanner, no manipulations applied. This one taken with aperture wide open, therefore, it swirls like crazy ))I received another Dead Link Removed today.
Looking good!! I wonder when the first images will be posted here on APUG?

I know several APUGers participated in this KickStarter project. (Dead Link Removed). Wonder if anyone has had any recent updates on the project.
I've taken some 120 film out of the refrigerator. I know the body will be here in a few days. Your image has set a very high mark for each of us. Nice work!
