Topcor Lenses

I have the 58 1.4, and while I like the overall image quality, I found that the Konica Hexanon 57 1.4 to have similar qualities but easier to use on my Nex...the konica being smaller in size. But recently I bought a Topcon Re 58 1.8 (silver version), which is much smaller, and possibly the sharpest of any 50ish lens that I own.
What I also like about the 1.8 is the focus throw. With the Nex "peak" focusing one can see how the focus travels outwards, and the area covered, in respective f-stops. It is really an overlooked aspect, I think, of a lens, because this relates to it's ability to isolate a subject. So, the 1.8 has much area in front of the subject and behind that is out of focus (if open)...remarkable lens.
Mine had a stiff focus mechanism (completely frozen at first) but the more I work it the easier it is.
I will try to post some comparisons in the near future.

Topcor loves blue...

I found that they like color in general, and only showing any weakness in high contrast light, none of my Hexanon's have given me a wow moment or even been impressed one bit, the Topcors can do that everyday I take them out.

Woodrim, gorgeous blue.

Lightshow as requested some wide open with busyish background from the 58mm 3.8 macro. The first is a fairly small snail against some moss.







and change to vivid mode in camera.

Did you mean to say LOW contrast light?

No, high, like around noon, when the light is harsh, you get stuff like CA, but in low contrast light like in the shade or on overcast days the color is great, blues reds and yellows all pop.

As a macro specialist, this caught my eye. Having done some searches, I find that it gets no mention in leading macro forums.

What are its "legendary" credentials?

I have never heard of a 100mm topcor macro unless you mean the 135mm. There is no literature I can find that references it. The Topcor macro lenses that I know about about are 30mm, 58mm and 135mm. I only own the 58mm macro and indeed it is a very good lens.

If you want a 50-ish macro lens, get a 3.5/55 or 2.8/55 Micro-Nikkor, a lot cheaper and incredibly sharp.

There is no Topcor 100mm macro to my knowledge.
There is a 30mm macro box kit @ $600, the lens alone seems to be half that.
These below are about $300 each and the black RE is more still.
5.8cm f3.5 and 13.5cm f4 bellows lenses, they require a bellows or the helicoid tube, or ext tubes to work.
Then the RE Macro Auto 58/3.5.
There is also 2 pairs of closeup lenses(Diopter lenses)(2 sizes) https://www.butkus.org/chinon/beseler/topcon_ic-1/topcon_ic-1.htm

There is the UV 100/4, but that's a different mount and not a "Macro" lens. I don't think there is a Helicoid tube for UV, just the Topcon/Exakta mount.

http://forum.mflenses.com/uv-topcor-100mm-f4-on-aps-c-t72494.html
https://www.flickriver.com/search/Topcon+UV+100mm/
IMO at best it's as good as the 58 & 135 Macro's.

Thanks, Lightshow.

So the 100mm macro in demoted from legendary to legend or maybe myth, at worst, typo! Laugh 1

Ian has an interesting history of producing less-than-accurate posts here on this forum.
While clearly referring to a Topcor RE when writing about the 58mm Macro lens, obviously he was confusing Topcor with Hexanon (in a previous posting he'd been comparing Topcors and Hexanons).
There is no Topcor RE 100mm macro with with matching variable extension tube.
There is, however, such a Hexanon, and i do own it - albeit not with the (rare) extension tube, but with the corresponding (high quality) Konica bellows.

I hope it's clear now!

Not really. Is it legendary? Laugh 1

Here is the original bayonet hood. Its diameter should be a bit over 62mm. You can try to guesstimate its height.

I got my first Topcon lens on Sunday. A UV Topcor 48mm f/2 attached to a winkEmirror camera.

A nice clean looking combination, but unfortunately the leaf shutter is stuck - it seems these are a real pain to service correctly, but flood cleaning might well do the job (still quite a big job) but the camera only cost £6.75 and I'm sure I'll enjoy the challenge.

Thanks for the link, I've found 62mm metal hoods no brand, which I suppose could do the job, but they are so many different heights. I can assume the height could be around 2 cm, but would be nice if somebody could confirm that, as if I'm buying a bigger one, ain't to easy to cut it nice.

You could get an original hood for it.

I believe the filter thread is 62mm, but I don't have a 62mm filter to test.

Thanks, but that's way too much that I've payed for the lens itself....

The genuine hood projects about 15mm beyond the front filter ring. It is 70mm in diameter. If the hood you're going to use is smaller at the end, it may need to be shorter.

Thanks you, I was about to get a 25mm long one in metal, but finally I should look for a plastic one, as it would be easier to shorten, I suppose,besides , the interior of the 62mm thread hood I suspect would not reach the 70mm in diameter, so finally , the length would be less than 15mm. We'll see. I appreciate your answer anyway.

The factory shades are actually nice. KEH (US based) occasionally offers them for as low as 40$.

With that said, the retention springs can compress causing it to mount loose. I had to use a tiny piece of double sided tape to keep it secure.

The benefit to mounting in the filter threads is that you can block the shiny chrome on the front at the same time. Not sure how much that impacts flare, though.
