Minolta Rokkor-TC 100mm f/4


Interesting! That's a lens still missing in my Minolta collection - I do have the 4/100mm Macro Bellow which is a triplet, too. The 4/100mm Macro Bellows [3/3] is pretty poor at infinity, unllike the later [5/4] construction.

I do have the Minolta Rokkor-TC 4/135mm and the 4/135mm Macro Bellows, though - they both seem to have the same optics; at least they seem indistiguishable at infinity.

So far, I have only had time for a short walk, so I don't know how well it works for infinity but it seems to be a very nice lens with nice colours and sharpness.

I created a small album with some of the pictures I took yesterday.

Can I ask you a question?

I love the rendering of the Meyer Oreston 50mm f1.8, and I've always heard the Meyer is a cheap version of the CZJ Pancolar 50mm f1.8. Is it true that both have similar bokeh rendering, but the CZJ is superior quality? I've never own both to compare, but looking at specs I see a difference; the Oreston has a minimal focusing distance of 30cm while the CZJ is 35mm.

Now that the Oreston goes for 150$+, which is the same price as the CZJ, if they have the same rendering, I might as well go for the CZJ. Do you or anyone can give some feedbacks?

(Also, is the Pancolar "auto" the same as "electric"?)


I would not say that the Oreston is the cheap version of the Pancolar. But it's true that in the Praktica Bayonet system there was a Prakticar 50mm f/2.4 that was the cheapest option, then a Prakticar 50mm 1.8, a new incarnation of the Pentacon 50mm, that was a new incarnation of the Oreston 50mm. And finally the Carl Zeiss Jena Prakticar was the high end 50mm 1.8, previously named Pancolar. So yes in that sense.

There are two optical versions of the Pancolar 50mm f/1.8. The first one has 6 elements in 4 groups. The second has 6 elements in 5 groups. These will behave similarly to a Oreston but not the same in my opinion.

I have also found that the Oreston with the early zebra style has the wildest bokeh (stronger bokeh edge highlights) compared later versions including Pentacon's.

For me I like both versions of the Pancolar and the early Oreston enough to keep all 3. It would be hard to choose one. With some patience you should be able to find a Oreston for much less than $150. For that price I'd take a Pancolar. Choose if you want the early version with yellow radioactive glass and 8 aperture blades or the later one without radioactive glass and 6 aperture blades.

A very good summary.
Thank you for that

Another Vivitar series 1. The 28-90mm 1:2.8-3.5 macro focus by Komine. Note the distance markings on the lens body instead of the focus/zoom ring.

Congrats. I received my copy last week with oily aperture blades. I have always been thinking of getting this blue VMC version, although I had the newer white VMC version long time ago.

Vivitar selected this Komine made 28-90, not Kiron made 28-85 as their Series 1, although the 28-85 is also a very good lens.

The Vivitar S1 Komine made 28-90 has been a excellent performer for me for a long time.
Congratulations.

I have that Kiron, but with massive fungus and lens seperation once optimistically bought for cheap thinking I could fix that Must see whether I can at least put it together again. :p My aperture is OK thankfully. Unlike my series I 70-210 2.8-4 Komine which is really only usable wide open. (Unless I don't lock it in place).

It looks sharp enough to me on first impression. Soft when used wide open at the long end, but that doesn't surprise much and is probably intentional for portraiture. Some of the Tamron Adaptall SP-2 glass may be sharper. But this range and brightness can't be found in AD2. The 27A 28-80mm 1:3.5-4.2 comes closest and that too needs to be stopped down in the long end.


Thanks for the information. I do like the 27A for the combination of weight and sharpness plus a very flat focus plane that is good for landscapes making for a nice travel lens. But vibrancy should be added a bit to colors when compared to Minolta's and yes you need to stop once at the wide end and twice on the long end. Compromises...

Enjoy the Vivitar and the benefit of a wider aperture.

Thank you for the great explanation. That helps.

I like the unique rendering of the Zebra Oreston, so I guess I'll try to be patient.

Yes, certainly. And if you ask why I have three sample of the Konica Hexanon AR 2.8/35-100mm ... well, the first one (an early EE version) was quite expensive at about CHF 200.--, the second one (an AE version) was much cheaper at CHF 80.--, so I couldn't pass it ... and the third one, in rather bad shape with missing rubber and fungus, was found on a flea market for a mere CHF 8.--. I know I should try to clean an repair it Wink

Performance is rather good as long as you stop down the lens to f5.6, quite comparable to contemporary primes such as the Hexanon AR 2.8/35mm (metal focusing grip). Wide open its rendering is soft and very much "1960s" style with lots of glow.

Do you know if Pentaflex auto-color 1.8 has anything to do with pancolar or oreston ? Thanks

The Pentaflex is a rebranded Oreston/Pentacon 50/1.8

The bargain of the bunch is the plain old Pentacon 50 Auto. That lens is superb for shooting flowers and things wide open, and you can still find them for 30 USD on ebay - occasionally even less.

Both give very nice results.
The Vivitar has more reach and range, and is still functioning perfectly.
The Canon nFD started to give trouble mechanically and so I sold it. Maybe the notorious plastic bearings were the problem - I am unsure.
The Canon FD 35-70 f2.8-3.5 is still going strong.
It is a stellar lens

Tom, your sample images show excellent results from this lens. For the nFD 35-70, my copy had the mechanical issue too; mine is the gritty zoom/focus ring.

Thank you. Actually I was thinking of the Canon FD 35-70 f2.8-3.5 vs the Vivitar. I happen to see the Vivitar locally for a not so high price and the Canon can be found cheaply on ebay which is tempting because it was such an expensive and good lens when it came out. I already have a Minolta and Tamron SP that are 28-80 or 85 but they open only to 3.5.

The Canon FD 35-70 f2.8-3.5 is so superior to the nFD in construction and materials quality in my opinion.
There is a significant difference in size as well.
The FD is well worth getting if you can find one
