hugo meyer petzval

I am lucky to find another Hugo Meyer atelier 360mm f3 petzval.

really big lens. more than 3 kg.

looking forward to the new lens board to mount them on my sinar norma

Is that f3 equivalent to a modern f3?

Does it fit on a Sinar board easily?

[tjuliuxue]

it is a modern f3, similar to dallmeyer b series.

the lens is too large for sinar 14 cm board.

I plan to use sinar 57 back stand as front stand and mount it on a home made sinar 57 lens board.

The Dallmeyer B series was advertised as f/3, but was actually f/3.5. Did Meyer do the same?

In my experience, yes, the Hugo Meyer Atelier Schnellarbeiter is actually about f3.5. This is based on measurements and exposure tests which I made with one 36cm version.

Jason is correct. The front of the Meyer's lens is not that big.

thanks, really helpful

The introduction of Waterhouse stops and then, later, iris diaphragms, implicitly lead to small decreases in maximum speed of the same optical design. An early pre 1857 barrel will be slightly faster than one with "internal brasswork!" to support Waterhouse stops. Iris diaphragms mechanisms reduce the optical diameter even more.

So the early Dallmeyer B portrait lens design (WHS) should be a little nearer F.3 than the "turn the barrel" versions with iris aperture. Unless the reported variations in focal length of this model (11-12") are real and are an attempt to keep the low F!

The same may be the case with the 3 generations of Hugo Meyer Petzvals. No stops - whs stops - iris aperture, with decreasing maximum speed.

Neither my Dallmeyer 2b or 3B has any intrusion into the barrel around the Waterhouse slot, and since the Dallmeyer Portrait Lenses came out in 1867, I doubt you'd find one with a pre-1857 barrel. But yes, I have some Petzvals with the aperture restricted by a baffle around the slot, or an iris mechanism. I'm not sure about the Mayer Schnellarbeiter.

I would love to see some sample shots.
Does anyone have a catalogue excerpt with coverage? I wonder how much the 400mm can cover...

[tjuliuxue]

also look for a catalogue

[Steven Tribe]

As all Petzvals are basically the same design, you can get an idea of coverage from another "brand" of 400mm focal length, F3 Petzval!

I can't find a catalogue for Hugo Meyer and he is not included in the new D'Agostini Germany lens book.

Well done!
Now we need confirmation that the rear cell has two independently mounted lenses? So France was not the only country to produce Dallmeyer Patent clones!
