Kodak Red Bellows Lens

Well, even if you were a keen photographer and have an interest to 

the old cameras, you may not know the Cameras with red bellows. 

They were 100 (110) years old Kodak Pocket folding cameras.

(I got two of them though they are in a box, bottom of the pile of

50 boxes = I’ll show you a photo one day.) — I bought just a lens in

a junk box of George’s Camerafare shop in the Portobello Market.

When the camera mean big wooden camera, Kodak started to sell

“Pocketable” folding cameras for the consumers.    (Be prepared,

the size of a pocket then could take even today’s laptop.   😀  )

We may guess, it was a situation like teaching the people to have a selfy

and send it through Net phone.    The Kodak preloaded the teaching App

on the camera body = all the instruction were written there. =Such as :

Use 1/100 for Moving Objects or Gray day, Use Tripod and with

B setting for 1/2 second !  ETC. ETC.  (Shutter was triggered either 

by pressing a lever or using an Air pump ! )  In fact I was rather

impressed to see the quality of the manufacturing standard =

after 100 years, they are still working ! )

The camera was made by Eastman Kodak Rochester USA though,

the Lens was made by Bausch & Romb Optical Co. Rochester, USA

(once before, Sunglass, Ray-Ban was a part of this company)

of which they call, Rapid Rectilinear lens. 

( though, it only meant, no distortion)

The second photo above center shows the lenses = front and rear

element seems to be identical (both showed the same focusing length

= symmetrical design)     And each lens seems to be a single lens.  

Mounting the lens on a bellows to have a test shot = seems not bad !

Thanks to the bellows extension — have look a close-up.

Then to see the So-called Softness on the same test bench. 

It seems this lens showed no Zeiss kind of softness. 

(The photo left was taken by Sony A7R —– to be fair, I did the same

shot on the Canon 5D Mk3 as before (right) —– in comparison,

Sony showed much higher crispness and Canon seems softer) —–

Still, this matter needs more critical test to find the reason.

Much more serious question over this old Lens IS, = No focal length was found

still, the extension of the bellows showed it is 175mm.   Even though the front

plate was saying F4, the diameter of the lens IS 24mm = F-aperture should

be F7.3 but from a measuring of the exposure indicates this lens got a

brightness of only F10. —– It is quite puzzling.

= To see the old lens is fun in deed, still it is not necessary a

gold mine to find any nostalgic image ! 

(Unless, use a homemade emulsion on a glass plate together)  😀

Such as like a photo of dried Rose by A7R — this sharpness might be

created by the digital process in the camera, not an original optical image.)

    That’s a beautiful piece of equipment, Yoshi!

      Absolutely. Since the equipment was crafted as an individual piece ! And after 100 years, it is still functioning as it was designed !
