New Toy Too (Two)
      #47527 - 01/30/04 12:57 AM Attachment (50 downloads)

I got a new toy also, well, old new. A 1968 Linhof Technika 4x5 large format field camera. It's mounted up on a Losmandy D plate, I've got the Schmidling vacuum back and film all ready to go, so of course, it's all clouded over!

The lens is a "normal" perspective 150mm f5.6, so depending how this experiment works out, I may buy a wide-angle lens.

Here's to more toys!

Whoa!!!!!

Thats a blast from the past!

Are you able to hold the shutter open with that one?

I just got my hands on a large format box camera too.....But it is fixed at one shutter speed.

Fun stuff though!

Didn't that once belong to Jimmy Olsen?

Cool looking camera. I haven't seen one in a long time.

The shutter's got a "T" setting so you can compose through the lens.

And, apparently I'm not as old as I feel: who's Jimmy Olsen???

I use to have a even bigger camera Suk. I use to have a 8 by 10 that looked just like that but it was not made by Linhof but did have a Carl Ziess lens. I want to say I think it was a 80mm, but I'm probably wrong, I suffer short term and long term memory loss like Dori.

It used sheet film and I had two plates you could load so you had two shots before you had to go find a closet to load more sheets. It was a lot of fun and boy did it have one heck of a lot of resolution. Can't wait to see whta your's produces.

Very nice. I don't know anything about cameras, but I'm impressed.

Suk:

I hate to tell you this, but your shutter is missing a part. Copal shutters have a lever that opens the shutter for focusing: the shutter should be cocked first. In your photograph, the silver "lever" furthest to the right should do this. The plastic lever that fits on there often breaks off on these old shutters.

Now you will have a lot of fun finding out how different large-format lenses are. The published image circle, circle of good illumination and circle of good diffinition, is usually determined at apertures of f/16 or f/22. Wide-angle lenses (wide-angle has a different meaning in large format) may not give acceptable image at the edges until f/8 or f/11. If you decide to pursue this, modern lenses are much better than old ones especially for color. You will see some great looking old Schneiders, Linhofs, and such on e-bay, but are only acceptable for black and white as the contrast can be very low. I resently sold a couple of Schnieders because their contrast could not produce acceptable results on Chromes (slide film in the professional lingo coming from Kodachrome, Ektachrome, Fujichrome, etc). But I do have a great Graflex Optar that does handle modern films very well, so it is not a hard and fast rule. But the multicoatings on modern lenses are very important.

Most ground glasses on the back of a view camera will let you see when barrel vignetting will occur with a particular lens. The ground glass should have the corners cut out. With the camera focused, look through one corner. If the aperture does not look round, the barrel is vignettting the image. While looking, stop the lens down until the aperture is round - that setting is where barrel vignetting ends. Your 150mm may be pretty good, but maybe not at its maximum aperture.

If you want a good book on this subject as well as other things on photographic technology, I recommend Materials and Processes of Photography by Stroebel, Compton, et al. I think the publisher is still Focal Press.

Good luck.

- Will
