On the 99005073 from front to rear side -> ( ( ((|)) )

Is that common knowledge or new information?

Thank your for the info.

The diagram you linked shows a RE. 6/4 scheme with 1-2|2-1 configuration aka Code 62B. This one is very similar to the older F 6/4 with the same 1-2|2-1 config.

According to the Topcon Story book, there was a change of design by splitting the first group. Resulting lens was a RE. 6/5 with 1-1-1|2-1 config aka Code 99B.

There was also an optical design called Code 129B with unknown config.

Your lens should belong to the Code 99B according to its sn.

Thank you. Whenever I take it apart again I will have a closer look at that 3rd element or first group. It did not look much like a single element the way it was encapsulated.

Yeah, I'm sure their diagram is of the 62B, so yours will be different, 111|21 as was posted.

I've started a page at Camerapedia's wiki to add in the Exakta mount lenses that were nonexistent, it doesn't have all the serial # additions this thread has accumulated, and I need to format the info better/more consistently, I was getting burnt out so I just saved it as a work in progress, here's the link: http://camerapedia.wikia.com/wiki/Topcon/Topcor_R%2C_F%2C_RE_lenses if anyone's interested.

If anyone comes across info for the following lenses, or the actual lenses, please let me know.
Topcor R 2.8cm f2.8 Preset
Topcor R 5cm f2.8 Preset
RE GN Topcor 35/1.8

Nice work.

A UK seller on ebay has two Leotax TV RF cameras for sale with the Topcor 5cm 2.8 lenses, one cleanish if you don`t have one.

If I understand you are looking for the fabled prototype lenses and more info on them?


PostPosted: Sun Jan 14, 2018 1:12 pm    Post subject: Reply with quote
Yes, I'd be in heaven if they had released the 2.8cm and 5cm R's.

I`m not convinced the prottypes saw the light of day. There was an avid Dutch collector/repairman who passed away and I reckon if he didn`t have any then they may not exist.

His entire collection has been catalogued/valued by some chap who likes doing these things but not selling them i.e. it`s a very authentic looking but dummy site and the lenses are not actually for sale.

The lenses and cameras I am led to believe are all genuine and were his collection, it now looks to be completed. You may have encountered it on internet travels, but if not....

Impressive collection!


PostPosted: Sun Jan 14, 2018 4:09 pm    Post subject: Reply with quote
It is indeed.

It was the first place I had seen a black 25mm 3.5, I know one or two forum members have one now but it did make me think they were just black painted chrome ones due the scratches in his pictures.

I check back the collection every now and then but it now seems to be complete. Haven`t had time to go through his serial numbers for the benefit of this thread....if anyone is bored.....

EDIT-PS interestingly although you can`t buy via this website I note one of the two 85mm 1.8 s he had seems to have been sold, I imagine the author has some access to his surviving family or estate.

I don't think they were ever released, but they probably survive somewhere, in someones home, someone related to a Topcon employee.
I had come across the lens pages many times, I didn't know they're of an actual collection, now I'll have to browse the site, so thanks for enlightening me about it.

I was looking at this page https://www.wesellyourcollection.com/topcon/product/04-topcon-super-dm-navy-set-body-sn-7209270-with-unique-collection-of-5-black-topcor-navy-lenses-navy-re-auto-topcor-58mm-35mm-100mm-re-topcor-navy-135mm-and-navy-re-auto-topcor-zoom-85-200/

And I wondered if the N which I had assumed identified lenses built to NAVY spec, was actually a lens coating spec for the NAVY, has anyone seen an reference to it's meaning? I'm also curious about if this coating is reparations technology from Germany that end up on these lenses from the NAVY Dept, Does this N coating (if different) have Zeiss T technology or if it's a coating that Topcon came up with?And is it the same as their M coating on the RE GN?

Hi everyone, I just joined. This is a great resource. Otherwise it's so hard to find information on Topcor.

I can contribute one new serial number to the initial list:

I own a "RE.Auto-Topcor 1:2.8 f=10cm Tokyo Kogaku Japan 752311" lens. (I did list all the digits - it only has 6). I browsed through the whole thread a bit fast, but couldn't find it mentioned before. I hope this is true. Maybe it's a preproduction model?

Also I can report that I own one of the (seemingly rare) 1.8/58s with s/n 9901... .

Hi,

Here you can see my RE.Auto-Topcor 1:1.4 f=5.8cm Tokyo Kogaku Japan.


In the listing of tao I found the following:
58/1.4 (Topcon Code 112B)

V1
RE.Auto-Topcor 1:1.4 f=5.8cm Tokyo Kogaku Japan 112xxxxx
Silver, with a kidney-shape grooving on the back
First known: 1120001
Last known: 1126233 {member Billou

I think, my lens is also a V1.

Why is not my picture displayed? It will be displayed in the preview.

I would like to add my collection to this list. Have a nice day.

*Re Auto-Topcor 35mm f2.8 Silver No Hood - 7408229 (White splotchy haze on the doublet forward of the blade and also the next element, otherwise centered well and snappy focus. Gives a low contrast. Could not find a solvent for the *grease induced haze*. One blade is slightly dented causing a slight unevenness when closed down) $$

*Re Auto-Topcor 35mm f2.8 Silver No Hood - 7418183 (Near Perfect - Much higher contrast than the last copy. A little white crud around the chrome screw on bayonet. Not sure how to dissolve this stuff) $$$

*Re Auto-Topcor 58mm f1.8 Silver No Hood - 11656467 Part of a Re-2 camera purchase (Nice - 75% loss of paint on side of front element. No evidence of flakes inside group. Likely from a CLA job ) $$

*Re Auto-Topcor 85mm f1.8 No Hood - 13300247 (Some small dust) $$$

*Re GN Topcor 50mm f1.4 - 15702219 (No visible yellowing but projection test side by side with 58mm does show slight warmth on white paper. A couple extremely tiny specs of black paint on the back of the front element. Focus is slightly stiff.) $$$

*Topcon Extension Tubes 1,2 & 3 - $

Nice collection! Keep it up Like 1 small

There are separate serial number sequences for the Macro-Topcor 58/3.5 and the RE. Macro Auto Topcor. Highest serial number I have seen for the latter is 13707913, a black anodized lens.

Hi, i am new here and introduced myself in another topic. See:

http://forum.mflenses.com/newbie-a-topcon-collector-from-holland-t80028.html

In short: i am a Topcon collector from the Netherlands and i have 95% of the Topcon stuf.....including all the hard to find lenses and camera's. Besides Topcon i also collect Aires and Beauty camera's and things. But still searching for more. I also collect all the Topcon related stuff, like brochures, service manuals, parts manuals, books, microfiches, pins, hats and so on.....Also TLR's which Topcon made with other brand names. I have lots of Topcon stuff and i loved it all. I am using one of my RE Super camera's to shoot pictures weekly.....mainly using Kodak professional 100 or, since one week Kodak Ultramax 400. But i have loads of films in my fridge. Love black and white and shooting mainly with the 1.4 or 1.8 lenses. I am a pro photographer with FF Canons together with my lovely wife...we do lots of (historic) motorsport....who works for Topcon.......

Almost forgot...i am collecting camera's for many years, but most of them are for sale locally here.....no heavy stuff just the normal names...Minox, Canon......etc.

By the way...i have read that some mentioned the book from Antonetto and Russo.....i am the lucky guy who found more copies then i needed...so i have some for sale. All new, but some have very, very slightly wear on the front......hardly to see.....so please ask if you are interested.....maybe the last change to find your copy.
