I just tok delivery of a Hanimex 600mm f8 preset lens. This thing is huge. One thing is very interesting. The mount, although looking like a M-42 mount is actually 46mm in diameter (or there-a-bouts). Are adaptors made that fit this thread? or what camera system could it possibly be for? I would love to use it on one of my SLR's for wildlife and motorsports shots. If anyone can help me I would be very greatful.
Thanks in advance.

Hi Heath,
Sounds as if it might be one of the 'universal fit' lenses, similar to the T-mount system and Tamrons Adaptall system, that is missing its adapter.
I haven't heard of an M46 thread being used at the back of the lens, but of course that's no criterion - there are lots of systems I've never heard of.
Hannimex bought its lenses from various makers so the name doesn't help an awful lot. Have you got a decent camera shop near you that might be able to help identify it?
I did a quick search on Google for "M46 to M42 adapter" but got a load of unrelated guff about telescopes. Maybe you can do better.
Good luck.
Peter W

I once had a similar “problem” mount with a lens. After much searching/asking it eventually turned out to be that there was a part missing - the manufacturer's mount!
Apparently these lenses were made with a terminating screw thread (not of a standard interchangeable lens mount size) to which was attached in manufacture various different camera mounts. The lenses were sold to fit different cameras and not as interchangeable mount lenses. It was never intended that this part was to be removable by the user.
Maybe this is the case with your lens?

One other thought, Heath. What appears to be the mount couldn't actually be an adapter could it? Try unscrewing it - what's beneath may turn out to be a t-mount.
Congratulations to the Aussie team btw. (Commiserations to our US members - you need a big striker, but I suspect the Czechs are going to do well anyway).
Regards - John

If I am not mistaken this is T mount threads and you would need the correct T mount for your camera

As far as I know Rick, the standard T-mount thread is M42 x 0.75mm pitch. The Praktica/Pentax M42 lens mount is M42 x 1.0mm pitch. I believe one is ISO Metric Fine and the other is ISO Metric Coarse.
There was, I believe, at one time an M39 T-Mount thread intended for lenses to fit LTM (Leica Thread Mount) cameras but I think it was discontinued.
Maybe there is another T-Mount thread in M46 size but, as I said, I haven't come across it. As well as for camera lenses, T-Mounts were made to fit cameras on to microscopes, astronomical telescopes, medical scanners, mass X-ray machines and possibly other equipment.
Maybe Roger's suggestion is a possibility?
As an interesting, but possibly not very useful, aside on lens mount threads, the original SLRs from KW that were the forerunners of the Praktiflex/Praktica cameras had an M40 lens mount thread. Possibly some of the early Praktiflex cameras also used it.
As far as I know, the old KW M40 lenses don't fit anything else, and I haven't heard of any adaptors for them - but there again, maybe there are some out there somewhere?
I was told it was increased to M42 at the request of Zeiss when they were planning lenses for the original Zeiss Ikon Pentacon (Pentaprism Contax) to give a larger throat diameter and avoid possible vignetting on some focal length lenses. While still in the planning stage the name Pentacon was dropped in favour of Pentax, but then Pentacon was revived and the name Pentax was sold to Asahi who also adopted the M42 lens mount.
So when people say that the M42 Asahi Pentax thread should be called the M42 Praktica thread neither is entirely correct. Originally it was a 'Zeiss Pentax' thread.
Some pundits who tell you that post-war design developments in Dresden and Japan, not mention the 'new' Zeiss Ikon in Western Germany, were jealously guarded secrets are quite wrong. Exchange of information appears to have been very free.
Sorry to have strayed from your original topic Heath! Hope you get your lens sorted out.

Thanks for all the information. The lens is deffinitely NOT a T-mount. I have a Hanimex 500MM reflex lens that is T-mount, as well as a 2x converter that is also a T-mount, so I have a visualisation of that mount. I have used my verniers to measure the thread diameter and it came to 46mm.
Roger, your suggestion is very valid. I will ask around a few places in the city when I am there this Thursday, especially at the place I am going to have my Selfix 16-20 CLAed, as being a dedicated camera repair facility, they should have an idea.
Brian, I was hoping to use it on my Praktica MTL-5, my Fujica ST605N and maybe also my Canon EOS 300D withM-42 adapter. I have no Nikon gear so there is no chance of the mount fouling on the contacts.

With Miranda Sensorex and T mount for Sensorex in hand I can say that the T mount is as Peter said a different thread pitch in 42mm mount. The Miranda screw thread is more like 42.5 or 43 (I have really cheap plastic vernier calipers). An M42 lens rattles in the Miranda mount hole but the Miranda T mount will almost slide inside my M42 mount Praktica LLC. Fits tightly in the Miranda though. M39 besides being Leica thread mount is also the mount size for older Zenit 3M SLR. Still perplexed on M46 though.

I looked in Matanle's Classic SLR book, he lists the Miranda screw mount as 44mm. Thought of YS mount: but it apparently uses the same threads as a T-Mount. Googled this> T-mounts are fixed, one-piece items, and T2 is two=piece, allowing for rotation (see below) Could the lens have the innerpiece of a T2 mount on it? Grasping here. I don't think so. Not if it's threated. The inner piece of a T-2 mount that's screwed onto the back of the lens has a V-groove and the outter collar with the mount threads or bayonet lugs has 3 or 4 set screws that allow positioning the lens as necessary and then securing in place.

I think the mystery has been solved. I did a bit of a search onn eBay and found two lenses that look identical to mine, but marketed with the Ricoh and Tokina names. It is a T-mount lens, but mine has the mount missing, and possibly some other bits. I have sent a message to one of the sellers and asked if they could take a couple of detailed shots of the mount end of the lens so I could figure out what is amiss.
Hopefully I can get the parts somewhere.

Twelve years late but this may solve your mystery. I have the adapter. Found it on eBay, thought it was a fancy T-mount in chrome. Turned out to be 46mm x 0.75 female and M42 male. I stumbled upon this thread looking for the lens it goes to. Here's a pic of the lens you may have and the adapter I have.
