Yashica 35 CC weird aperture

[blee1996]

Recently I bought two Yashica 35 CC, and both had this weird aperture blade problem.
Looking from the back of the lens (with backdoor open), the aperture has a weird shape
after stopping down. It is not round, but a irregular star shape (photos below).

I bought one from KEH and one from eBay, and both had the exactly same problem,
So I wonder if it is a common problem with this Yashica model.

If it is, is it possible to fix yourself? If not, who will be a recommended person to work
on these old Yashica compacts? Yashica Guy still around?

Thank you!

You are jumping to conclusions. Not all apertures are shaped as you might imagine.

Do the pictures come out OK?

If it ain't broke.............

This is how the shutter and aperture work. Yashica designed it this way. This is a good camera! Have you used the cameras? Why do you think something is wrong with the aperture? Some examples:

Give old Butkus a couple of bucks when you download the manual; he deserves it...

"Exposure Control : Fully automatic exposure

Many compact cameras of the 70s and P+Ses of the 80s, especially those with electrically controlled exposure/apertures, used a small number of aperture blades, like 2-4 blades, often producing a somewhat star-shaped aperture (or cat-eye for the 2 blade types) at intermediate stops. I think some of them may even use the shutter blades to form the aperture, but don't hold me to that. Anyway, users, especially users of these entry-level cameras, were less obsessed with round aperture shape than they are now. They just wanted correct exposure.

I would guess that your camera has 4 blades and maybe is supposed to form a 4-pointed squarish star aperture and is a little out of adjustment, but I'd also be inclined not to mess with it unless you can establish that the exposure is off.

You guys could be right, let me try to take photos first before jumping into conclusions. Thank you all.

Your aperture has two blades, so that odd shape is normal.
It is not Abbie-normal.
