Nokton 58mm f1.4 have the same optical schema as this Topcor so -
Voigtlander 58mm f/1.4 vs. Topcor 58mm f/1.4 -http://forum.mflenses.com/viewtopic.php?t=11638&view=next
To adapt the Topcor 5.8cm/1.4 to sony you need a lathe and some work. It is easy, but not so simple =)
Only multicoated Topcor lens for the Super D (and other Exakta mount Topcon cameras) is the RE GN Topcor 50mm f/1.4 lens. Unfortunately, that lens was built with radioactive glass, and they all have "tan" glass by now. It was quite a sharp lens.
The 58mm f/1.4 lens is a tank, a lot of glass, but only single coated. Sharp, but probably not as sharp as the razor-sharp 58mm f/1.8 normal lens.
There is an 85mm f/1.8 Topcor, about a thousand made, rarer than even that would suggest, shows up a few times a year on eBay, selling for over $1000.
Of the RE Auto Topcors, the only real disappointment is the 200mm f/5.6. Very slow, and not really that sharp. Most of the other Topcor lenses can do 80 lp/mm without really trying, even at wide apertures.
RE Super (outside US), Super D (US through Beseler, later rest of world not through Beseler), and Super DM are tanks of cameras. Very reliable. The RE-2 (outside US) and D-1 (US through Beseler) is also a good camera, but the shutter speed linkage to the Copal Square shutter is fragile.
The US Navy used Super D cameras in the Orion sub surveillance planes flying on the west coast. They special ordered lenses with an infinity lock, which are maked with a red N on the dress ring. It was a hard life for those cameras.
As for the leaf shutter Topcor cameras (Uni, Unirex), they are incredibly unreliable, have a great deal of mirror and baffle shake, and the UV Topcor lenses are mostly dissapointing. The IC-1 body should be reliable, but the lenses just aren't worth the trouble.
Topcon's biggest problem was probably Charles Beseler Company's distribution, especially compared to what Nikon got out of EPOI. More focus on "fair trade", and protecting dealers from each other, than from competing with the competitors.
The new Voigtlander 58/1.4 Topcor is a new optical design and styled after the classic 58/1.4 Topcor, even down to the Topcor's bayonet on lens hood. These are limited edition lenses, with 800 each announced to be produced in Pentax 42mm screw mount and Nikon AI mount. The lens barrel is out of place in today's plastic lens world, with real classic style chrome, looking just like it came off Topcon's production line in the 1960's. The lens barrel is beautifully made, and rather amazing in the "find any way to make it cheaper" manufacturing times. Side by side the new Topcor is a bit smaller than the original, so the hoods will not interchange. Specs: 7 elements in 6 groups, multi-coated, f/1.4 to f/16, 9 aperture leaves, 58mm filter size, close focus to .45 meter or 1:5.8, weight 305 grams (Nikon).
