Looking round a local market the other day I spotted a guy selling his photography stuff and bought these.......
Firstly this £8

The part that fits the camera is much smaller than what's needed...so can I buy the correct thingy? if so what's it called? if not can I buy an adapter to fit the thingy and my camera? and what's it called?
This is the part that fits the bellow and camera.

Also....I know I don't really need this but for £2 I thought it would give me a slightly better understanding of exposure shutter speed and light.

I get the basic....turn asa dial for ISA/ISO...turn other dial until pointer lines up with needle, which will give you your aperture and shutter speed but and i'm presuming E.V stands for exposure value? but what is it telling me?
Sorry if these are stupid questions, I have searched google but come up with little to nothing which helps.

The bellows are fitted with a Carl Ziess Jenna Tessar 50mm 2.8 lens...Which I've read are hard to get hold of???
Ta in advance.
Ken.

For some reason the pics are only linking? Sorry! and probably should have put this in Cameras, Lenses and Accessories....
 
If it was me, Id be off to my local camera shop (not jessops) to find out what kind of fitting the bellows are, and it will probably be the same fitment as the lens. It should then be a fairly easy job to find an adaptor. It looks from google that the lens is possibly a praktica one, which would make the fitting probably m42 bayonet type, plenty of adaptors for that to canon kicking around on ebay.

Are the bellows themselves intact?


As for the light-meter, sorry, can't be of much use!
 
Thanks Gandhi, the camera shop is my next step, just not got the time yet.....just thought I'd ask here incase someone knew. The bellows and lens are in very good condition, a little dusty but for £8 i thought it worth the risk....They have cleaned up nicely and aren't marked or holed in anyway.
 
The Exposure Value readings on the meter are derived from the aperture and shutter speed at a given sensitivity (ISO/ASA/DIN).

Take a look at http://en.wikipedia.org/wiki/Exposure_value for an explanation and a table. :)

I believe that the Unitor bellows were available with several different mounts, but can't really tell from the pics. They come up for sale from time to time, so worth Googling! :)
 
That Carl Zeiss Tessar 2.8 lens is really crisp. Well.. not a bad tenners worth Ken. :)

Bellows came in two types - automatic and non-automatic. With the Automatic versions you got a double cable release.. a sort of 'Y' shape, one end screwing into the front mount on the bellows, and the other into the camera shutter button. Pressing the cable release then fired the camera AND stopped down the lens aperture to the actual exposure aperture. (Obviously it's desirable to compose your shot with the lens wide open for the brightest image)

With non automatic bellows, you simply stopped down the lens by hand before you took the shot, which is what I'm guessing that lever is for on the front lens mount.

The good news is that I would think these would still work in AV mode with a modern Canon providing you can get the necessary body adapter. I'd think you can.

Because of the enormous extension possible with bellows you can get much greater magnifiction than 1:1 ..more than most macro lenses. The bad news is that the Inverse Square Law applies, which dictates that every time you double the lens extension, you quadruple the exposure needed, and you can end up with enormous exposure times. A modern TTL exposure system should relieve you of all the mental arithmetic though, and handle the exposure for you.

The other thing is that as you extend the bellows, the viewfinder image becomes darker and darker to the point where focusing is difficult, even in good light. It goes without saying that they're really meant to be used on a tripod. :)
 
Thanks Silky, just been having a read.
CT....the lever on the front locks the lens in the bellows.....the lens has an aperture ring which can be changed from 2.8 to 22.....I haven't had a chance to use with the camera obviously but have looked through it myself and doesn't seem to dark (maybe because the camera is not connected) but the magnification and detail is amazing, yes the lens does seem very sharp and just can't wait to try it out now.
Thanks again guy's.
 
Went to our local camera shop today with the fitting for the bellows to camera....asking if he had a one for the 350d or an adapter. He told me he wasn't sure what kind of fitting it was because there are that many different kinds and the best bet would be to try Jessops :thinking: :bang: :bonk: :annoyed: :shrug:
Got some close up pics I'll post later if anyone has any idea.
 
Don't know too much about what has already been said here ... :thinking:

But ain't it great to have new toys to play with ... even old ones ! :D

Look forward to some cracking close ups when you get your connexions sorted Ken ! :thumbs:
 
Thanks Ven.
Ok in the hope that someone knows what kinda fitting this is to save me going to Jessops.

The upper part fits to the camera body and has 3 lips while the lower to the bellows and has no screw or lip....just slots in the hole and held by a screw fitted on the bellows.
Anyone?
