Verito 14.5 inch

[Two23]

Just bought one of these and intend to use it on a Kodak 2D 8x10, mostly for tin types. Looks like the flange barely fits on a 6x6 board, and unlike a Petzval the entire lens hangs off the front of the camera. What diameter of hole do I need in the lens board for this lens?

The hole for is 4.25” and the OD of the flange is 5.29”. It mounted on a 6”x6” board with room to spare.

Just reread your post, don’t know if it make any difference but mine mounts right behind the aperture ring.

I mounted mine on a 5" board once, it is the one in studio shutter that hangs entirely off the front, and I didn't have a flange for it. There are filter holders that take a 105mm (?) internally threaded ring, I bought one from China off eBay for a couple bucks, it was a perfect fit for the lens. I machined an aluminum lensboard to get a bit more rigidity, since the edges were so thin, and I screwed my 'flange' to that by drilling 6 holes evenly spaced around the filter ring, with smaller matching holes in my aluminum lens board, then #2 self-tapping screws to assemble. The lens was held perfectly perpendicular to the front standard and held firmly in place.

I got lucky and found one custom mounted to a Sinar board:

I received the Verito 14.5 inch lens today. Overall it's in nice condition. This one mounts flush to the lens board and does not protrude into the bellows. It also has a very thin slot for stops. Reading up on it, looks like the stops were for when lens was being used for enlarging? Lens is not coated. Not sure how many leaves the iris has but it is a lot! The forward half of the barrel unscrews.

I do have a question. The writing on the bezel says the lens is "Diffused Focus" but I find no dial for diffusion. I might be confusing it with the Velostigmat Series II which I was also considering buying. This is the f4 version. Doing some more reading looks like the lens was made before 1946. Further reading makes me think the lens was made between the 1916 updating (from brass barrel to black enamel) to the 1920 update which discontinued the slot for stops. Specifically, between 1917 and 1920. Do I have this right? Since Zbima1 is taking some time off making lens boards, I'm going to cannibalize one I already have and cut a bigger 4.25 inch hole with a coping saw. I'd like to mount this puppy and see what it looks like on the ground glass.:)

Taking the lens apart I discovered the numbers "3308" had scratched into the housing for the aperture leaves. I assume this is some sort of reference number for manufacturing?

With the Verito, the softness is determined by the aperture.
Supposedly it starts being sharp around f11.
The Velostigmat with "Fuzzulator" has adjustable SF at all apertures...and can be modified for more diffusion.

If that is the serial number, it was made in 1913. The lens usually has a serial number on the outside somewhere.

I’d propose 1914 since that was the year Wollensak’s catalog first described the lens barrel as “polished black” as opposed to the earlier “lacquered brass.”

You can find a reference on the Verito as an enlarging lens with diffusing stops here: https://alphaxbetax.files.wordpress.com/2021/04/1917-verito-diffusing-stops_osu.pdf

Lens is barrel, polished black with brass underneath, has a slot, is f4. In a stroke of luck I also have a 36cm Heliar mounted on a 6x6 board and the hole fits the flange of the Verito perfectly! All I need to do is take off the Heliar and mount the Verito. I can then have Zbima1 make me another board for the Heliar. I intend to do some outdoor portraits with this lens, mostly with wet plate. By shooting in the shade I should be able to get away with 0.5s exposures. I want to try taking portraits of ice racers on Sunday out on a frozen lake with the lens. Supposed to be below zero F so too cold for wet plate. Will try shooting FP4+ using ND filters over the lens to slow exposure down to something around 1s. Will bring a 1920s Velostigmat 12 inch in Betax just in case I need a shutter and something wider. The Verito is in pretty nice shape for something over 100 years old.

Be aware you’ll have to adjust focus for wetplate. The bit of remaining chromatic aberration of the Verito plus the very orthochromatic chemistry means the blue/UV is a bit behind of the greenish that our eyes are most sensitive to (had to check Stroebel to make sure I got the direction right)

Uh oh. An issue. So, looks like I'll have to focus where it's sharp, and then pull the focus just a tiny bit closer for wet plate?

Don’t worry. It is a Verito. You won’t be able to find sharp focus wide open anyway. 😀

Oh, it's easy to find! It's all over the place!

(Actually, the achromatic doublet at the rear corrects the Verito fairly well, though not perfectly. Most of the Verito's soft effect comes from spherical, not chromatic, aberration. Just err a little on the short side during focusing.)
