So i took a put on an old Super 8 video camera being interested in re purposing the lens. Turns out it's not so much a lens attached to a camera as a lens is part of the camera system, built in together.

The lens actually has it's final element set back behind the external aperture, and behind the lens helicoid. You could, theoretically, bend the plastic housing to change the focus operation Razz

The external aperture is electronic, 2 x leavers controlled by a small magnet that is infinitely variable.


Kind cool looking design, again this is floating within the housing of the camera body, and only sealed by the plastic housing.. and not sealed, well it's a snug fit as apposed to any mechanical gaskets. Below you can see the final element removed form it all.

The range finder is kinda cool too. Various elements glued into the housing before a cheater right angle flicks it in front of the aperture.. Actually if that's the case, perhaps that rear element does nothing. It might just reverse the image. Hmmmm


Anyway, with the lens more of less deconstructed like a tacho, I've lost motivation to continue. I would have to reuse the housing, make a new one and it's clunky / not going to serve as I thought it might on the little Pentax Q.

Oh well. that was still fun Very Happy

I also suggest the Sankyo Super CM, now might just stay in once piece and live on the shelf behind me, it as a similar looking bulge for the view finder and I can only assume shares a similar design philosophy, with the lens being part of, and not, a part.

Pardon the late reply, I don't drop in here very often anymore.

OP, what you showed us is typical of S8 reflex cameras with integral lenses. C-mount reflexes (C-mount Beaulieus, ZC-1000, ...) have taking lenses that are complete and can be reused fairly easily. Integral lenses often have optics between the beam splitter and the film and between the beam splitter and the eyepiece. Its never been clear to me whether these are relay lenses or parts of the taking lens.

Yeah very true. Makes sense I suppose as far as manufacturing is supposed, and kinda fun to see their solution to integrating everything.

Back to stalking early 8mm cameras for their C and D mount lenses for me
