[Greg]

Some info from 1998? Wisner catalog:

4x5 set: five cells: 250, 250, 350, 400, 450 #1 Copal $3,239.50
5x7 set: five cells: 250, 350, 400, 450, 500 #1 Copal $3,637.70
8x10 set: four cells: 350, 400, 500, 600 #3 Copal $4,107.40
Master set: six cells: 250, 350, 400, 450, 500, 600 #3 shutter $4,810.30
yellow filter for 4x5 & 5x7 set $65.00
for 8x10 & Master $85.00
Corrector fits all sets $85.00
Have heard of only one or maybe 2 sets actually being out there after all these years

I find more interesting: 140 degree Wisner Hypergon 84mm f/22-45, Lens in rotary sector-shutter with B and T settings, "waterhouse" stops: $2495.00 Center filter $382.00
Never heard of anyone ever actually having one of these.

Thank you for this, I've not been able to locate my Wisner catalog. It's my understanding that the No. 1 Copal shutters used here were modified so as to have the same size mounting thread both front and back. Well they'd have to have been for the system to be workable.

The "Zero Power Corrector" may be even rarer. I remember years ago, I think on the rec.photography newsgroups, there was an individual who would periodically complain about having ordered the "Zero Power Corrector" but had yet to receive it.

There's a review of the Wisner plasmat set by Jean-David Beyer on the LFphoto main page, dated Oct 1997: https://www.largeformatphotography.info/plasmats.html
I think he used to post to the rec.photo. large format Usenet newsgroup. He ordered the zero power corrector but as of that writing hadn't received it.

There's also a Wisner catalog here: https://www.largeformatphotography.i...MonoChrome.pdf
Note, the transcription above has a typo. The Zero Power Corrector was actually $650. I would guess that few were ordered and (IMO) it was probably never shipped. Wisner's copy text says that "It occurred to us it should be a simple matter to design a cell of null power ... with sufficient corrections" etc - I don't know if it really is that simple.

Thank you very much for this. I remember the name Jean-David Beyer from the old rec.photo large format days. I'm sure he's the one I remember complaining about never getting his corrector plate (well as sure as I am of any memory anymore.)

Looking at the catalog you cited, I see Wisner credits Zeiss with the Hypergon. I think it was in fact C.P. Goerz Berlin who originated it.
