There have been many posts on the forum about Topcor RE lenses and their desirability.
There are also Tokyo Kogaku lenses, presumably from the same manufacturer.
Some questions for whoever might know......
Would it be correct to assume that anything branded Tokyo Kogaku would be older than the Topcor/Topcon products?
Has anyone experienced using any of the older(?) Tokyo Kogaku lenses, and in particular the longer telephotos.
What mounts do they usually have on the back - bayonet, M42?
Any other information would also be appreciated.
Many thanks

Thanks for that.
I had done some research before asking the question and had discovered this web link.
Unless I've missed it, I didn't see any reference to lenses branded Tokyo Kogaki.
Plenty of Topcon/Topcor, Simlar, Toko etc but I can't find any branded Tokyo Kogaki
This is the image that has aroused my curiosity:

It would appear to be made for Exakta mount cameras then.
Does anyone have experience of this lens.

Many long years ago I used a Topcon SLR for awhile. Tokyo Kogaku and Topcon are the same company and I believe TK lenses are older - it's just the name on the front ring that changed at some point. The Topcon focal plane shutter SLRs and Exacta SLRs shared the same mount and I am not aware of those Topcon (or TK) lenses being made in any other mount. Of course I am leaving the Topcor UV lenses, meant for Topcon's leaf shutter SLRs, out of the equation. It's been over 20 years since I held a Topcon in my hands and I may be wrong, but this is how I remember it. Topcon made great quality glass by the way. |

Thank you for the information.

Not sure yet.
I will let you know.

Probably the most definitive site about Topcon cameras , lens and origins is at the Topcon Club Japan website, if you can tolerate the google transaltion it`s worth a browse, info on the 20cm 4 is here..

It's a great little lens, I'm using it on my NEX-7 and getting sharp results wide open.

I have the 200/5.6 RE and while it is quite good, it is of course too slow. I have the 300/5.6 R as well and it is a stinker, although there are fungus issues. _________________ Regards,

The black R series are older than the RE series, but just as good.
I love the RE 5.6/200, not too slow at all and it's sharper wide open at 5.6 than just about any faster 200 is when closed to 5.6. _________________ I don't care who designed it, who made it or what country it comes from - I just enjoy using it! |

All of the Tokyo Kogaku lenses for the Exakta-mount Topcon cameras are branded "Topcor". Older lens caps have the company name, "Tokyo Kogaku", newer lens caps say "Topcon".
The various series were:
R. Topcor: Preset lenses (90/4, 135/3.5, 135/2, 200/4, 300/5.6, 300/2.8)
Auto-Topcor: Auto-diapraghm lenses for Topcon R, with external shutter button to control stop-down (35/2.8, 58/1.8, 100/2.8)
F. Auto-Topcor: Auto-diaphragm lenses for Topcon R-II and R-III, with lever on back to control stop-down (35/2.8, 58/1.8, 100/2.8, 135/3.5)
RE. Auto-Topcor: Auto-diaphragm lenses with full-aperture through-the-lens metering for Topcon RE Super and RE-2. (Focal lengths from 20mm to 500mm.)
RE Topcor: Lenses made by Cima Kogaku with same features as RE. Auto-Topcor, but of lower cost and quality, for the "Topcon" RE200 and RE300 cameras. Cima Kogaku made these lenses in many other mounts, sold under many brand names, including their own Cimko brand. |

Thanks John.
So do the older Tokyo Kogaku lenses have Exakta mount, M42 or other?

There are also LTM(M39) RF lenses, I have a silver Topcor-S 50/2, its a nice lens, as solidly built as my silver Canon 50/1.8,
There are also a couple black versions of the 50/2, same with the 50/3.5, & a 35/2.8, a collapsible 50/3.5
There may be more but that's all I've seen while browsing. _________________ A Manual Focus Junky...
