Antic Camera ? — Doppel Anastigmat Lens

OMG !  —– In an odds and ends box in a camera shop, among the modern

high-tec camera or broken lens kind etc, I found a 100 year old camera !

It looks pretty much like German Ihharge kind but, this one was very small.

Before roll film was invented, the camera then was using a glass plate as a 

photosensitive material.   And a contact print was a way to make a print

= hence the size of the glass plate was often “Postcard size” —– though,

this camera was using “6 cm x 4.5 cm size” so, pretty small in deed as

you can see from the photo above. 

On the lens, it was written “Steinheil Munchen Doppel anastigmat 1:5.4  f=7.5cm”

— Doppel mean Double, so the lens seemed to be a symmetrical design of

stuck of a convex meniscus and a concave meniscus placed both side of an iris.

(altogether 4 lenses)    Back of the camera has detachable focusing glass.

= After framed and focused, focusing glass has to be changed to the glass plate

to take picture. 

75mm lens for 6 x 4.5 cm photo size mean, this was a camera of so-called

medium format camera ( such as Hasselblad, Rolleiflex etc) and the 75mm

lens could easily be used on a 35mm DSLR body — which I did with a

help of Pentax Helicoid Extension Tube. (on Nikon or on Canon) —– what

I realized was that this lens doesn’t have a clear crispy sharpness of the 

modern lens, but neither beautiful softness. (of a kind what I like)  in other

word, it was just an old dull lens ! (No mythical subtle touch of “old lens” ) 

I can see the character of this lens here still, I wouldn’t pretend to be a

master to appreciate this softness = it is just a lack of sharpness which

never improve with smaller F-aperture. (this photo was fully open = F 5.4)

(Lens got a lots of fungi = can’t create any sharp photos anyway.) 

The lens was mounted on a Pronto (later called Prontor) shutter — and

amazingly, after 100 years, they are still functioning. (more or less)

The photo above left was shot by using Pronto shutter 100th. (while

5D’s shutter was open with B setting, then click Pronto shutter)

and the photo right was a comparison, Pronto was opened on T setting

and a photo was exposed by the 5D’s shutter.

Something peculiar on this type of  camera then was that the most of them

were having  “Lens Rise control” ! —– Do you know why and what for ?

Set the camera on slightly low angle (about waist high) — thanks to

the “Lens Rize” (without looking up) it is possible to take picture of the

whole body, while making the leg looks longer !   🙂
