What mount is this ? Auto-Sankor 135mm -f2.8

<p>I don't know how this ended up in my collection, I have looked at it over years and still have no idea what mount it is. The diaphragm pin is solid and does not retract. Also the braket on side moves back and forth as shown in pictures. I see online a guy reviewed it and it looks like something worth testing as the glass is new. <br /> Any clues?

<p>my browser is having serious problems with that link.<br>

rich oleson had]s a " lens mount identification page"<br>

Judging ONLY from the arm sticking out of the lens, It MAY be a Miranda sensorex lens,<br>

the Mirandas had a shallow 4 prong mount male on the body<br>

one "claw" on the back or the lens.<br>

if the short arm which would be on the left side of the lens when mounted and a small pin to link with a matching arm on the camera body. that is what it is.,<br>

the short arm will move tha aperture settings. max opening would be at the bottom.<br>

I have several old miranda senorexes so this is familiar to me.<br>

I do not see a noth on that arm, that would mean Nikon.</p>

<p>the miranda sensoprex was superceded with the senorex EE and the DX# that did not have the small arm<br>

the company went out of business in 1976,<br>

later "faux" mirandas were either M42 or pentax K mount.</p>

<p>it by noticing the screws holding on the bracket with the small arm<br>

a YS mount lens, this is a T mount lens but with an auto diaphragm.<br>

It was available from most older lens mounts like m42, exacta, Miranda, . canon FT ( stop down metering) and other cameras of that era. oh yes from Nikon F. the mount was shared with several other companies that made or marketed lenses besides Spiratone. some Good others likely just OK.<br>

Since I have miranda senorex cameras I am interested if you have no use for it.<br>

these lenses were usually made before plasic became popular in lens construction. the lens is likely heavy.</p>

Walter you are welcome to it if you like. If you pm me your address i'll let you know how much to send it by registered post from Ireland. </p><div></div>

<p>Walter's first guess is right, I think. The T4 mount has a similar inverted bayonet, but also always includes indexing marks for aligning the aperture ring of the adapter, and a lock on the outside edge for locking in the adapter, and would not have that protrusion for the meter indexing. Meter coupling would always be on the adapter, not the lens itself.</p>

<p>The Sensorex version resembles the earlier meterless versions of Miranda lenses, except for the meter coupling, which was added on the outside much as the meter prong was added to the outside of the Nikon lenses, so an earlier lens could be converted easily and remain compatible. </p>

<p>Since I'm probably one of the few people in the world other than Walter who actually has a Miranda in working order, and mine is not a Sensorex, it sounds like just the thing for him. </p>

<p>while we are o the subject-sort of- I was disapointed when the miranda D and DR would not accept any other lnses and still have an auto diaphragm.. thewre was and I have an exacta XM adapter for preset exacta lenses but the axm adapter tht inverts the auto-exacta lens and allows it to be used on any miranda as an auto diaphragm lens is a very Pricet adapter.<br>

I wish I could use my Xa adapter a t4 lens with a exacta adapter and be able to use a few more lenses on my ld model d body.<br>

despite the age or exactas both the t4/exacta adapters and genuiene auto exacta lened are very expensive as well as rare.<br>

Of course that was 55 years ago and I now have many choiced for my newer slr's.<br>

but ld thoughts and hops die hard. strange that I want some of the same thing at age 80 that I did ast age 25.<br>

The mirandas were good cameras for that time. I bought it based on the removable prism..<br>

but that was then not now.</p>
