8x10 lens board size

[raizans]

i was just wondering why lens boards for 8x10 cameras tend to be so large. it seems like many people use smaller technika boards instead.

[Jack Dahlgren]

Bigger camera = bigger lenses
bigger lenses = bigger boards

technika boards can take copal 3 shutters. maybe some other reason?

If that's the biggest shutter you use, then you're set. But there's a lot to life after Copal 3.

Just barely, and even then the orientation of the lens has to be just right to clear the locking mechanism. The shutter also has to be mounted more in the center of the board, making the tilt axis a little off.

Canham lightweight 8x10 uses a small board:

I used to wonder more why so many American folding cameras, Premos and the like, had such small boards.

If I had an 8x10 with a board too small to take a #5 Compound I would feel restricted. I wouldn't want to mount a brass cannon, but if I did I would feel frustrated.

Because in the old days the brass lenses were HUGE. My Grundlach-Manhattan takes a 7 1/2 in lens board and my Ansco takes a 6 inch board.

Together with a "behind the board shutter" like the Grundner shutter one needs a 9 inch lens board as used with the Linhof Kardan and Sinar Norma from the Fifties.

good to know. i never heard that before.

There are several lenses in Copal 3 that have rear cells too large to fit through a front standard designed around a Technika board.

Large len board is great if you have BIG len!!!!!

If my Tachi can accept 6inches len board, then using Aero 12in won't be a problem.
Now, I need to drill hole on the len barrel.

what size is too big? if it's the maximum diameter of a copal 3 shutter, 102mm, the only lens i know that's larger is the 480mm f/8.4 apo-symmar-l (110mm). i could only find comprehensive specs on schneider and rodenstock lenses, though.

Try stuffing one of these in your Technika:

The 6x6 boards on my 'dorff accept #5 Universals. It is a good compromise but I'll never be able to slap a big brass Vitax on her! :(
A lot of very useful old 8x10 lenses ride in #5 shutters, btw (10" WF Ektar, 14" Commercial Ektar. 375 Ilex, a whole slew of Wollys.)

The opening in the front standard of the Master Technika is something around 85mm, maybe a hair less. Other cameras that accept Technika boards generally have similar openings, though sometimes they're smaller.

Just looking at the early-90's vintage Rodenstock and Schneider catalogs that happen to be within easy reach, I count nine lenses that won't fit. There are others.

Hey, that closed at quite a nice price for a late 210 SA. If you've got the forklift...

could you type those down? i only have access to the current catalogs that are online. at the moment, this is my list of lenses that have rear cells larger than 85mm:

480mm f/8.4 apo-symmar-l (110mm)
600mm f/6 apo-tele-xenar (90mm)
800mm f/12 apo-tele-xenar (90mm)

90mm f/5.6 super-angulon xl (86mm, 78mm without lens protection ring. doesn't cover 8x10.)

if anyone out there has specs for nikkor and fujinon lenses, that would be greatly appreciated!

[Vaughn]

I have 5.5" boards -- too small for the Apo Nikon 600/9!
