790mm F:5.4 LF & ULF Lens Data

[Reinhold Schable]

It's been 9 days since the 790mm f:5.4 Wollastom Meniscus lens was introduced.
Since then I've been quite busy.
There's a bit more involved than hacksawing off a piece of plastic pipe and hot-glue mounting a lens...

I am not resting (I bought one) either. I needed to make many mods to my Levy Process camea to handle this lens. Extension box lens board is complete. I did some initial sharpness testing at all apertures, by shooting my GG with digital.

I could shoot 11X14 right now, but my DIY 11X14 back is slow to use.

Tonight I am finishing a 8x10 reducing back, using a Calumet C1 back, actually I will be able to mount any C1 back. Test with Fujiroid.

In between hacking, sanding, gluing and painting, I have been working out a sort of ring flash set up with 3 SB 800's. I have no shutter and will focus with string and use the lens cap and hand fire the the strobes. Tested all that with digital, works great.

Also converted an old Sachtler & Wolf wood tripod to mount a Saltzman tripod head. It should be HD enough to hold the big Levy in the field, if I ever do try that.

Next I need to make a 14x17 extension back.

I should be shooting 8x10 tomorrow, baring Hell or high water. We have been flooding, Chicago area.
