Taylor, Taylor & Hobson - Cooke speed panchro Ser.II 75mm f/2

[Spyderman]

Somehow this lens found its way to me, and now I don't know what to do with it...

Originally it's a 35mm cine lens.

It has no focus mount, but the glass is clear (although a bit yellow overall). Fortunately no fungus, no haze and almost no cleaning marks.

I'd really like to make a usable lens out of this...

Any ideas where to get a mount for it?

The first option is to use a SLR mount - that way I wouldn't need RF coupling and I could focus it on the focussing screen. Some people have done it and got some rather nice results (see here (http://www.dchome.net/viewthread.php?tid=422331))

The second choice would be to use mount from a damaged Leitz Hektor 73mm f/1.9. But that lens seems to be a colector's item, and I bet even a mount fetches higher prices than I'm willing to pay.

But what if I still wanted to use it on my Bessa and Zorkis ? I was thinking a mount from the last series of Jupiter-8 (where the RF coupling ring rotates when focussing) could be used, and the RF-coupling ring could be filed down (similar to RF coupling rings of Summicron-C and Elmar-C lenses for Leica CL).

Or maybe if I could find a machinist capable of making a mount for it ...

Any advice would be greatly appreciated. :D

I've got one of these grafted onto an M-mount that was cannibalized from a broken Leitz lens.

I've also got a 50mm Kinoptik f2 on a collapsible M-mount from a busted Summicron.

Here's a similar adaptation for M42. This seller has lots of converted lenses, take a look through his stuff for ideas.

I tried to hold the lens in front of my good old OM-1 with an extension tube, and the image seemed quite good - nice bokeh, bright and contrasty.

I think I'll try to put it in an OM-mount. For this purpose I need some OM-mount lens with glass in bad condition. Best would be focal length between 50 and 135...

How big is that lens? There just might be the chance, if you could mount it (perhaps a bit recessed) on a set of bellows, that you could still retain infinty focus. You would have to find a set of bellows with the least amount of extension fully retracted, though, to have a shot. I've used a 105mm lenshead on two different sets of bellows. On the first (a Konica unit) I could focus just a bit beyond infinity, and that wouldn't work with a 75mm lens, but with the other set (a 3rd-party can't-remember-the-name-brand for m42) I have at least a couple of centimeters of bellows extension when the lens is at infinity, maybe more (sorry, I don't have it here right now so I can't measure). If you could borrow (or have) a set of bellows it could be worth trying.

This would probably make for the easiest solution (least machining anyway), and I found the setup quite usable after a while. People look at your camera as you walk about town though...

Still, reshaping the focus cam on a Jupiter or using it in another lens mount would be a much more elegant solution. I happened to have the original focusing mount for my lens and eventually adapted that for m42 instead, but using it on bellows worked.

Well, the rear tube of the lens is just a bit (maybe 1mm) fatter (at 29mm) than the opening on a J-8 focus mount. With some filing it would fit.

The rear screw-mount is 1+1/4'' (or 31.7mm) and the rear tube protrudes 22mm to the back.

As I tried to hold it in front of a SLR (OM-1), and it won't focus to infinity before touching the mirror :(

So the only chance is RF, or macro on SLR...

[Spyderman]

OK, so I just checked it and I think it would fit the J-8 focus mount. It might even reach infinity focus.

I'd like to file the rangefinder coupling ring down like a ramp, similar to the RF coupling of Leica CL lenses.
EDIT: not file down, but rather add material to make a ramp...

Now I just need a J-8 focus mount - the one in which the front and the aperture scales rotate as you focus.

(I have one, but it's my best J-8 and I wouldn't like to canibalize it - it's in the picture below)

Good luck - looks interesting.
