Topcor 58mm f/1.4 adapter

[mattbenn8]

I just picked up a Topcon re super with a Topcor 58mm f/1.4. It's beautiful. I've done some searching but I can't find a definitive answer to which adapter to get. I'll be using it on a 5dmkii. I don't want to change the mount to m42 because I want to be able to use it on the re super body.

Anyone have any experience with this on a full frame body?

Thanks. And I'll post some pictures as soon as I have some.

Let us know what you find. I have the RE, AUTO-TOPCOR 58mm mounted [in your honor] on my 5DmkII right now... and the mirror hangs.

I have the conversion kit to m42 in my desk, but I can shoot the lens with mirror-up, so I'm procrastinating.

My 58mm is in cm, so it’s a 5.8cm, and I "just" noticed a wide tab on the end of the rear lens block. I bet that is hanging my mirror, as this tab must be the deepest reach into the cam. Probably an important tab for your Super!

My m42 conversion kit is reversible, so it’s a non-destructible conversion I have converted a few Topcors to m42 already.

I converted mine to A-mount for my Sony A900 (FF, of course) and really enjoy it. Actually, my wife adopted it on her A300 and uses it almost exclusively.

Though it won't help you directly, you could probably do the same thing I did. Removing the back mount and bolting on an M42-Canon adaptor (A-mount in my case of course). Tap the adaptor so the screw holes line up with the original mount (because there is no M42 to screw it onto of course) then just put it on in place of the original. You may need to shim - I had to trim. You may even be able to bolt it on over top the original, with slightly longer screws. I showed my result over at Dyxum.com -

Always love the look of your images Kelly.
Please let us in on the work-flow would you?

The second one is great. I like to see these images, it's 20-30 centimeters of snow here...

Ok. Thanks for the tips. For now I just took an OM adapter(it fit best) and super-glued it to the back of the Topcon. It's nowhere near the proper distance and I can only focus out to about 12 or 15 feet. I know it's not ideal, but I wanted to see what the lens could do. Here are the results of my first quick shots.




So far I love this lens. It's reasonbly sharp and the bokeh(which is one of the main reasons I picked it up) is very smooth. It's also much more color neutral than my other thoriated lenses or my zuiko 55(which seems too cool sometimes).

Now...I need a permanent mounting solution. Has anyone tried any of the hong kong made adapters with the 5d? I would ideally like to be able to pop it on and off between the canon and the topcor super, but if there's no choice I'll do some surgery.

Bruce...mine is the 58mm silver lens and it also has the tab off the back, which seems like it will make it hang on the mirror(it did with a thinner mount that I tried before I attached the OM mount).

Kelly...your pictures are beautiful. How far out are you able to focus?

Thanks,
Matt

The tab on the back of the lens mount is there just to make it safe to put down the lens on a table without scratching the protruding rear element. Removing it would do no optical harm.

There's a smaller version on the 28/2.8 and the two GN Topcor 50mm lenses.

The M42 replacement offered on fleabay is a fully reversible operation. I use the 100/2.8 and the 35/3.5 this way. The 135 will be done soon too.

Just ordered one here, waiting with bated breath to use the TOPCOR RE Super 58mm f1.4 on my 550D

Privet Attila, thanks for the welcome and clearing that up for me, I was getting frustrated trying to pass on the link.
This looks like an interesting and friendly Forum, looking forward to exploring and sharing information and knowledge.

I have a 1,4 Topcor, too, second version, but still with 5,8cm instead of 58mm.
Made me an adapter for my Sigma SD14 (no infinity, around 5m maximum) just to try it. I didn't manage to get out of our garden with that lens right now, so here are just a few non-artistic shots.
All (except number 3) at 1:1,4.
I love that lens!

Lovely samples Klaus!

Is there adapter available for UV Topcors without aperture mover ring like here: Click here to see on Ebay.de

I have mint 4/28mm and would like to try it on EOS.

[ManualFocus-G]

I believe UV Topcors have a different register distance and thus can't be used on Canon EOS cameras

[cambug]

Topcon used to make an adapter to adapt UV Topcor mount to RE mount, but it is quite difficult to find and could be the reason why UV Topcors are so cheap and not sold easily. The is also a major difference between the two mounts: the aperture of the UV Topcor lenses is adjusted on the camera body ( like the DKL lenses ), so to use it on other camera bodies, a way has to be devised to adjust the aperture apart from mounting.

[Joosep]

Been testing my Topcor 58 1.4 for some time. I got the newest.. 4th gen that is. Been loving it.
Adapted it to m42. Using with my Bessaflex.

I just finished my last exam, got some more free time now.
Gonna post a topic sooner or later.

[Pancolart]

Thanks! I guess a way would be to obtain defect TOPCON camera body and take down aperture mover?

[cambug]

This could probably be done as I have seen report that somebody did take out the mount from the camera body and modified the rear end as an adapter. However this could be a complicated process and requires service of a professional, have to decide whether it is worthwhile or not.

[John Shriver]

Yes, someone did take the lens mount from a Topcon IC-1 to use as an adapter for UV-mount lenses.

Note, however, that the UV-mount lenses were Tokyo Kogaku's "economy" line, and they are nowhere near as optically good as the RE Auto-Topcors. Reviews in Camera:35 magazine were pretty awful. Not really worth a big investment in using them.

Similarly, the RE Topcors (without Auto in the name) are really Cima Kogaku lenses, no great shakes. However, the RE Topcor 200/3.3 does fill a "hole" in Topcon's lens lineup -- a fast 200mm lens. (The RE Auto-Topcor 200/5.6 is slow and not that sharp to boot.) Of course, those lenses also came in many other mounts (with other brands), including M42, Pentax K, Nikon, etc.

I have the 25, 35, 58 and 135mm RE lenses. I use a cheapo ebay adaptor from ebay for my 5DII. The mirror hits the lens flange for all lenses. So I had to file down upper part of the all the lens flanges a bit. I also had to file down the aperture pin in the back of the lens to be able to mount these lenses on the adaptor. 35 and 135 now have infinity focus. 25mm does not go all the way to infinity but infinity is within the depth of field at f5.6. Hope this helps others.

Here are some pictures from the 58. Actually a 5.8cm 1.8 f.auto
