Hello,

Does anyone have any information on the ltm 50/1.5 Nikkor now for sale on Ebay? The serial number is 732822, and the diaphragm steps down to f16.

Thanks
 
220639201140 is probably the one OP is referring to. Must be pretty special, already over $500 with 7 bids, with 6 days remaining in auction

It first looks to be a J-3 lens module mated to a Nikkor 5cm f2 Ltm focus unit .
the aperture ring nr. are set going the wrong way for a J-3 though.
The Nikkor LTM version of their 5cm f1.5 had just the dot on the movable aperture ring like the later Nikkor 5cm LTM lenses.

check out the pic of the lens this ebayer is selling.
No DOF scale is engraved, too complicated to do to match a f1.5 unit.
Easier to grind off the old scale and just leave an alignment dot for a focusing indication mark.

Good guess - hadn't occured to me.

The DOF scale could have been re-used - would have looked suspicous without f1.5 though. Wonder what was done to the aperture ring.

Plus, it might work really well optically. Better than an LTM J3 anyways. :)

Well Roland, a Sweeneyfied or Coxoned J-3s work pretty good if it was a non soft lens to begin with, but I would not want to sink over 500 dollars on a disguised J-3 thinking it was a rare collector's gem.
 
Agreed :) Still getting a beater Nikkor 50/2 and replacing the glass sounds almost reasonable. Then again, the original Nikkor 50/2 is a cool lens all by itself, and not as cheap as it once was anymore .....
 
Yes the f2 Nikkor in LTM or in the Nikon RF mount is still a great lens although even at Camera Shows in Toronto of the 1980s it still sold for 125 to 180 dollars, it was never cheap, although I did snag a Nikkor 5cm f1.4 LTM for a 110 dollars back then.

This ebay mystery "Nikkor" lens could be cobbled up from spare parts that some camera tech had on hand, it would be worth more than the sum of its parts if it is sold to someone that does not do their homework.

P.S the seller's lens with three knurled focus grip rings is not very Nikkor like though.
I wonder if Brian Sweeney would chime in to clear this mystery.

The thread should probably be moved to Brian's "Mad Gearhead Scientist" forum, then.

Home from work- just saw this one.

Bizarre. The J-3 optics module will not fit into a Nikkor F2 focus mount.
 
I can't decide if it is a Canon lens "rebranded" as a Nikkor, or a "rare, early, hand-made, one-of-a-kind Nikkor". (just in case someone here bidded on it)

The F-Stop moves in the direction of a Canon and Leica lens. The Nikkor, J-3, and Simlar all move opposite of this one.

The serial number is in the wrong format to be a Nikkor 5cm F1.5 lens.

If someone here wins it, I will take it apart for them.

Do not bid above $125 on it.
 
What a queer bird that is.............hmmm I don't get the missing "Tokyo" the f1.5 was long gone by the time the "Japan" theme came around too, were's the Nikon experts???

The Serial numbers don't jive with the production f1.5 stuff, and "meters" too, strange not PX language there......is that a Leitz Xenon mount???? Strange????

I'm with Brian on this one, don't think it's worth over $125

This is not a Nikkor!
The typeface is wrong, the serial number is wrong, the barrel is wrong!!
It is an unusual something but it certainly is not a Nikkor.

I'll ask Bob.

Bob Rotoloni called it very strange!
He said he has never seen nor heard of such a thing.

The serial number gives it away, if it was a one of a kind it would have a one of a kind serial number not a 6 digit number.
The engravings on the barrel is so not Nikon.
The infinity symbol is not correct to the period, Nippon Kogaku did not use the lazy 8 symbol until the middle of the 1950s.

As they say in Baseball, 3 strikes and you're out.

I love a mystery... According to this site which lists every type of Nikon and its serial number range, this lens should be a:

F 45/2.8 GN Auto NKJ LMIJ 5- 7 blades 725743 - 733948 23848 1970 - 1971
- as the serial number falls in the range.

Close, but no cigar ;) That website lists every type of F-mount Nikkor lens and serial number ranges, but it does not have any Nikkor rangefinder lens information :p
