Have a look here:

This is a Canon (?) macro lens repaired with the front ring of a standard 50 mm Zuiko. There is a 135 4.5 macro lens that looks like this one. There are some pictures known of a prototype with a different focussing ring (just like the one in this picture). Finding that prototype would be something!

> Hi Daan, thanks for your info. Are you sure about it being Canon? Did you see / have these images to c&are? Thanks Klaus

Klaus,

I am not sure about this lens being a Canon lens. The chrome ring that connects it to the body looks like the old Canon (FD?) type. Canon lenses of that time have the same focussing ring (but so did Nikors). It could be a home made lens al together, composed of all sorts of parts. Searching Google doesnt get anything looking like this lense. It should be a bellows mount or short mount macro lens. Probably in the 100 - 150 mm range. The Olympus 135 mm could never be fitted with the front ring of a 50/1.4. The glass is much to large for that.

My OM lens chart only shows macro lenses in the following configurations 135 F4.5, 80 F4, 38 F 2.8, 20 F2

Macro F2

I just observed on the B & H website that Olympus now has a macro 50mm F 2.0 for $699.99.

There website shows one manual focus 50mm F2 and another auto focus 50mm F2 lens which is cleary for the E1. Check out their photos.

AFAIK the OM macro lenses are:

20mm f2.0 Bellows lens 20mm f3.5 Bellows lens (old manual type) 38mm f2.8 Bellows lens 38mm f3.5 Bellows lens (old manual type) 50mm f3.5 50mm f2.0 80mm f4.0 Bellows lens (old manual type) 80mm f4.0 Bellows lens 90mm f2.0 135mm f4.5 Bellows lens

There is an AF 50mm f2.8 macro for the 77, 101 or 808 or whatever those cameras were called And there is the new 50mm f2.0 ED Digital Zuiko macro for the E-1 (can't wait for that one :)

There is a 38mm f 3.5 for the PenF series that was used as a 'prototype' for the 38 mm bellows lenses)

Mr. Schmidt
Daniel Tan is right. The shown lens is definitely a normal lens for the FTL (M42). I wonder why that site refers to it as a macro lens. As far as I know Olympus never made a macro for their FTL system.

Hi Yall,

the nback thread mount is 1" (25,4mm) is is far from M42 (i.e. 42mm) - that is why it is mysterious for me (still)
 
>I would still say that this is an FTL lens or rather it has been. >Apparently someone has replaced the 42mm screw mount with the one you see >in the photos. Hence the alleged 'macro' capability which did not come with >the original construction - the lens is not marked 'macro' anywhere on it, >is it? not to mention the amazingly wide aperture. F1.4 on a macro???

As said before, this is a 'home made' lens using the front ring of a standard OM 50 mm f1.4 lens. The rest looks like a 100 or 105 mm f4.0 macro head. Could be Canon.

Hello All! Herr Doktor,
did You try mounting it on a movie-camera ...?
(I fear You do not own it, though; only, We may stay at the website's photos. Is is so?).
I must say, at first it works out the same impressions like with Daan.
But I strongly think, it is a genuine Olympus objectiv from FTL serie: both newer OM System and older FTL made 50mm/1,4 and both which marked as "G.ZUIKO - AUTO-S" (OM 50/1,8 says "F.ZUIKO") and both NOT Macro; but its barrel is of FTL one. _
Mounting it on a 8mm or 16mm movie-camera, it became! a Tele-photo by different film-frame size (like mounting a 35mm lens on a not full-frame Digital Camera). _

Should be verified if it does focusing according with the distances printed on the focusing-ring; if so, it means that mysterious mount is well calculated in its length and then a Tele-photo focusing from cm.40 (1.3 ft.) may already be well called as a macro lens. _
If tube-mount lengthens, objectiv can focusing nearest; but We may take the best quality, on the first case.
The 1" screw mount is properly a standard mount for movie-lenses. Also, don't forget many movie-cameras were made as Reflex, too; then, easily allowed to take macro films.

I do not think it as a home-made lens; I think it a limited production, yet based on an Olympus FTL 35mm Lens 42x1 (Praktica) screw thread mount Model and modified into a 1" screw mount version for movie-cameras.
You might make further research among web.sites regarding cine/movie equipments.

Thanks for reading, Greetings from ITALY!
