The hood has a silver nose. It is a beautiful lens.

Minolta Rokkor-TC 100/4? Haven't seen any reliable info on this one either.

In addition there's also the Minolta Rokkor-TC 4/100mm for bellows. The latter is clearly optimized fo shorter ranges; it's performance at infinity is terrible. Lokking at the published lens sections, one can assume that the non-macro Rokkor-TC 4/100mm does not have the same optical construction as the 4/10mm bellows.

I recently received a Bellows Rokkor TC 4/135mm and i could compare it to my (non-Bellows) Rokkor-TC 4/135mm; this would show whether they are different or identical optical constrictions.

Cheers for your replies guys about my 100mm f4.
I just looked up the TC version and I don't think mine is that. Mine does not have the aperture towards the end of the lens (like a preset, as I see on pics of the TC version), it is in the standard position off the top of my head. Though the hood I have for it definitely looks like the TC version hood. I'm at work at the moment so can't actually check.
It was Mothers day on the weekend so I didn't get time to take a picture of the lens to show you guys. I will try to do that asap, time permitting.

Ok, I'm an idiot.
Just got home from work and checked that lens.
I remember I purchased it as a Minolta 100mm f4 a fair few years ago now. It arrived. I checked it was clean, put it in my lens cabinet... and there it sat for a good few years, till mid last year when I finally mounted it on my camera and took a few snapshots of the kids wide open. Really impressed me. Great rendering. Shot some with it again recently. Still really like it. Great portrait lens. Very 3d character to it's rendering of faces.
Anyway, checking just now, turns out it is infact a Minolta auto tele rokkor-qe 100mm f3.5. I never actually checked the front plate properly. I always just mentally labelled the lens as 100mm f4 as that is what I purchased in the listing originally. Thankyou so much for the replies. Sorry for wasting your time and also sorry for hijacking this thread.

Don't sweat it, haha.
I've recently received this very lens and have a bunch of raw files patiently waiting to be developed and posted to the "Bokeh Only" thread.

Spoiler: it did good.

Tele Rokkor 100 QE is a good lens. Marginally less sharp in the corners than modern computations but probably to the benefit of bokeh. So a very good portrait choice.

The MD-III 4/100mm Macro is exceptionally sharp and free of CAs even in the infinity range, and wide open!
The MC/MD 3.5/100mm Macro is less so, having slightly "unsharp" corners at f3.5 and, to some extent, also at f5.6.
Finally, the Minolta Rokkor-TC 4/100mm for bellows has a really low performance at infinity.
