Anybody had any recent updates on Petzval lens Kickstarter project

[Nodda Duma]

See here:

(there was a url link here which no longer exists)

The design can be scaled for medium format, but the lenses would be different due to the different focal length. But there's no reason I couldn't run a separate Kickstarter for each except it'd be double the work. I'll think about the best approach.

I could do it for any design for which there is interest. But let me focus (haha) on the new RR first.

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

"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.

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

Bill, I'm so glad to hear that!

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".

Just say it is a special dyslectic 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.

Denys wrote this about his Petzvar lens being a genuine Petzval design:

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.

And he shows a nice list of several other lenses with P6 bayonet mount as well on his site (scroll down): http://ivanichek.com/Medium format Petzvar Petzval lens.htm
Since I don't have any other P6 mount lenses yet, I now know what to look for to put on my Kiev 88CM ;-)

Has anyone a good tip for a "sleeper" P6 mount lens in the range of 30 to 90 mm? Meaning it being very good but not too popular this cheap? I like B&W, landscape and street photography mostly. I'm not familiair with the brands and lenses on his list.
Obviously, I'll have the 120 mm Petzvar lens for portraits.

I received another Dead Link Removed today.

(...) 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. (...)

Looking good!! I wonder when the first images will be posted here on APUG?

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 ))

Nice. And I just saw that there are Pentacon Six lens adapters to my Mamiya 645 camera and to my Leica R camera out there as well (besides for Nikon, Canon, etc.). So I'll ask one of those for my birthday (only a 3 months wait) so I can use the lens even more often.

 

[darkosaric]

Nice indeed !

 

[yurihuta]

I received mine last week - Pentacon Six mount. I am very pleasantly surprised as it is very nicely made! I have a Pentacon Six to Pentax 645 adapter and will try and try it out sometime this week.

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!

I feel a friendly contest coming up
