That's understandable Wink
I only saw one once, when I was picking up some stuff from a nearby collector. It was an MD-III (which well may be the rarest version of the MD 4/7.5mm Fisheye). I was looking like new. The guy had paid CHF (USD/EUR) 70.-- for that beast ...

I paid 359£... Sad ... very pricy and is a MD Rokkor version looking mint with the cardboard box, but could not resist after 3 weeks of hesitation...

Yes, you'll enjoy that one Antoine!

The only Minolta ROKKOR / MD lens that actually has any gears in it (for the built-in filter rotation mechanism, the 16mm fish-eye uses a different mechanism).

Be very careful with that front element though, things that look a bit close in the viewfinder will be nearly touching the glass...

CHF 70.-- Stephan? Seriously ??? Shocked

EDIT: £359 is not a bad price at all Antoine; I paid more for mine and that was more than ten years ago...

Yep. Things like that do happen, occasionally.

My Thambar was CHF 100.-- twelve years ago. It was on a flea market, and I didn't really know what I was purchasing (back then I was only into Minoltas). I did have a (non-working) Leica IIIa, inherited from my mother, and I thought an additional lens with about 100mm focal length would be nice. Only later I finally discovered what I had bought, and I still feel ashamed - but there's no way I can find than guy ... I don't even remember the name of the very small village ...

Shit happpens ...

Finally - last but not least - a nice Zeiss Contina with a Novicar Anastigmat 2.8/45mm. Is that a triplet? Or a Tessar design?



Congrats for your rich catch!

As far as I know, Novicar as well as Novonar is an iteration of the Novar triplet. I used BW film in an older Contina, a cousin of yours. It was equipped with a Novar with max aperture of f3.5, and I was impressed with its contrasty and sharp rendering, on par with the Tessar-like Voigtlander Skopar. If you wish to entertain yourself with a film roll, this simple camera would let you some pleasure of use.

I just got the camera on top of other stuff. Sadly, it isn't in a working condition - the shutter is blocked, and I don't think it would be easy to fix.

A silly question: is it possible to attach say a Sony FE 1.4 converter to a camera, then a Minolta to Sony adapter and then a Minolta MD lens ?... (to get a say 560 mm from a 400 mm...)

You will create more distance between lens and converter that way. That will probably make you loose infinity. Just try it I guess.

... a few rather humble vintage lenses from the waste bin of our local photo shop ...

* Revuenon 3.8/35-105mm
* Tokina AT-X 3.5-4.5/35-200mm
* Tamron 3.5/70-150mm (20A, the newer one)
* Auto Tamron 4/70-220mm with rubber focusing grip

The Revuenon 35-105mm as well as the Auto Tamron 70-220mm have a rather mediocre performance (and "mediocre" is probably an euphemism). This sample of the Tokina AT-X has a fogged lens surface in the front element and therefore I can't really comment on its performance - however, it seems to be pretty good for a vintage zoom with such a wide zoom range. Finally the Tamron 3.5/70-150mm (another euphemism - in reality it's more a 4/75-150mm): the experts on adaptall-2.com say that it has "above average" performane - but it can't compete with the Canon nFD 4.5/70-150mm or with the Minolta MD-III 4/75-150mm.

In addition there was aslo a beautiful Zeiss Contaflex Super BC, but that one is shown in another thread:

I have both versions - 20A & 20AB - and I really like them, one of Tamron's best offerings.

Mamiya Sekor EF 1.4/50mm - one of the very few Sekor E/EF lenses that were still missing in my small Mamiya collection! The lens is pretty rare here in Switzerland - in fact I had bought one when I was 16y old. Back then, Mamiya sold off their 35mm SLR stuff, and I got all the "fast" Sekor E lenses (2.8/28, 1.4/50, 2.8/135) plus a few others (3.5/50 Macro, 4/200). Not much later - when I got my first Minolta 9000 - I gave the whole set of Mamiya stuff to a classmate. Only a few years ago I started collecting that stuff again, and apart from the Sekor E 4/300mm now all Sekor E(EF) lenses are in my collection Happy Dog.

Pics will follow as soon as the lens has arrived.

EDIT a few old Zeiss lenses are on their way as well - an early Zeiss 6.3/12cm Tessar, a later 4.5/15cm Tessar, and the front half (?) of a very early Zeiss Anastigmat 1:12.5 F285 m/m with SN 22047 !

Plus a Kodak Anastigmat 7 1/2" f4.5, and an Optikotechna Brerov Belar 4.5/210mm ...

I had the 20AB and liked it, gave it to my sister. I think Tamron supplied the 4/70-150 to a number of big companies in rebadged form.

Of all the 70-150s I've tried, which is maybe a dozen, they were all pretty good - a 2x zoom lens is easy to design & make.

I remember comparing the Konica Zoom-Hexanon 70-150 to the excellent Hexanon 3.2/135 on a dull, gray day on Whitehaven beach and the zoom was only a hair less sharp when pizel peeping, the contrast was noticeably lower though.

Not a silly question; there are very few of those in life Wink

I think this should work (at least in terms of infinity focus; I can't guarantee anything about control of aberrations...).

In your suggested set-up you maintain the correct mount register:

1. The FE 1.4 converter is designed for the E-mount register of 18.00mm, so if you put this on a Sony E-mount camera, the 18.00 mount register of the FE 1.4 converter + Sony camera is maintained, i.e. the image of the main lens should still be projected 18.00 mm behind the front (lens) mount of the FE 1.4 converter.
2. A Minolta SR (MD) to Sony E-mount adapter will accommodate the difference between the SR mount register of 43.6mm and the E-mount register of 18.00mm. Those adapters are therefore 43.6mm - 18.00mm = 25.60mm long. The Minolta MD lens will project the image 43.6mm behind the SR mount of the adapter, and therefore 18.00mm behind the (front) E-mount of the FE 1.4 converter, as designed.

You can use two setups really for which ready-made components exist:

using E-mount FE teleconverter: E-mount camera -> E-mount teleconverter (FE) -> SR-to-E-mount adapter -> SR-mount Minolta lens.
using SR-mount teleconverter: E-mount camera -> SR-to-E-mount adapter -> SR-mount teleconverter -> SR-mount Minolta lens.

In both those setups the teleconverter's own image and subject positions (TC's subject = lens' image) are maintained as per their original design parameters.

Control of aberrations is a different matter. I'm not familiar with the compatibility of the FE 1.4 converter as far as suitable lenses & their exit pupils is concerned. Given that its FE designation indicates use for the full-frame E-mount cameras, and given the relatively small E-mount diameter, I am making the heroic assumption that the FE 1.4 converter is designed for lenses that are not too exit-telecentric in nature and therefore do not have an exit pupil too far ahead of the mount. Minolta's own MD lenses > 300mm have exit pupils that are reasonably far forward (hence the recommended use of Minolta's 300-L teleconverter and not the 300-S), so these may not be an ideal combination as far as control of aberrations is concerned. Really only one way to find out...

I have the EF 50/1.4 and I like it a lot. Congratulations!

Listed as excellent condition, I think it's MD mount, we shall see how it compares to the Series 1 35-85mm f2.8.



"写真レンズの基礎と発展(小倉敏布)'95"

This is "Fundamentals and Development of Photographic Lenses" by Toshifu Ogura (ex Minolta employee)- a book which has been talked about a handful of times on he from 1995.

This contains many, many rare lens diagrams from compact rangefinder/AF cameras, a smattering have filtered through to the English web. I can't find the thread from here which included one or two. On the Japanese-speaking web, you can find a few more pages/diagrams pulled from it:








etc. There are probably more out there, I remember seeing a few.

This is one of the well-renowned books, up there with Kingslake's History of the Photographic Lens.


Needless to say it they be scanned in at high res...[/img]

Yes, I remember that from a previous thread - I'm curious to see whether the earlier Sekor CS 1.4/50mm and the newer Sekor E/EF 1.4/50mm have identical properties.

Back in the mid-1980s when I acquired my extended set of Mamiya Sekor E lenses I was quite disappointed about the image quality of the fast 50mm at f1.4. I had bought it to shoot landscapes at night (with Kodachrome, that is) - and of course Coma at f1.4 was terrible. Not knowing (yet) about its potential for portraits I immediately stopped using it at f1.4 ...

I rarely have used the Sekor CS 1.4/50mm, simply because there's no dedicated adapter for the Sekor CS lenses. I have slightly modified my "Fotodiox pro" adapter for Sekor E/EF lenses, and now it's possible to stop down the Sekor CS lenses as well. However, it'd not an elegant solution, and the aperture values are not really precise.

Haven't been able to find much on this one.
It's in nikon f pre-a/i mount.
Looks a bit curvy in the FT-2's viewfinder.
I'll get it converted soon.
Looks chinon with the narrow chromed focus ring.
In my digging around I found an identical image of this lens with Hanimex markings.

As much as I would like it to be a Tamron, it will take a bit more convincing for me.
Rear construction is a lot different, and this is not an adapt-all of any kind.

Pretty sure that lens was made by Sun Optical or one of their associated manufacturers. It was sold by Tamron as a Tamron lens, but the serial number on Soligor badged versions seems to indicate Sun Optical.

As with most of these secondary market lenses from Japan during that era it is really hard to say for sure. If I were guessing, and it would be just a guess, I would guess Tomioka, Only because I have seen similar livery on clearly labelled Tominons. Though not on a 28.2.8. The chinon (tomioka) shown by lightshow is very distinctive and that pattern with the 2 bright lines separated by pebble grain leather with orange distance markings I am 90 percent certain are ALL tomioka. I have challenged folks here to show me an example clearly made by another manufacturer. So far nothing. But I will add I read somewhere (probably on here) that the lens industry bought components from each other and did spec manufacturing for each other. So it becomes exceedingly difficult to define the makers of a large proportion of these lenses.

That Chinon 35mm lens also appeared in a large variety of other liveries, so it's maybe not advisabl to use the focus grip design alone to determine the manufacturer. For these examples the commonality can be seen through the depth of focus scale, focus markings, and the design of the rear element holder. The Tamron name on one lens confusingly may not necessarily point ot Tamron as the manufacturer. The '7' serial on the Soligor may point toward one of the manufacturers comprising Sun Optical at that point, although serial lists on the internet can often be inaccurate. Bottom line, Tomioka is not ruled out, but using just one design element to identify manufacturer may not lead to meaningful conclusions.

A further example is the 28mm lenses from the same manufacturer, in an even wider array of liveries:

Thanks for the informative reply.
This kind of effort always helps a lot.

I sort of suspected it might be hard to pin down a maker.
I have actually run into this sort of thing before, looking for the maker of another different 28/2.8.

I got the conversion done tonight.
The aperture ring is quite a bit smaller than nikon original pre-a/i f mount.
I have it working on the the D-810.
I.Q. is a bit better than what I was expecting.
I'll get some test shots up here later on.
The name ring and filter thread tube are one unit.
It threads off counter clock-wise.

Edit:

First frames.



Wide open at M.F.D.



f5.6 at M.F.D.



L.E.D. lighting at M.F.D. f5.6 and ISO 1600 hand-held.



Outdoor overcast at f5.6 .

The age of this lens is apparent~ especially wide open at close focus.
Slight and odd distortion when focused for distance.
I suppose sharpness is o.k. as long as it's stopped down a bit.
Color is very close to actual except for reds, without any manipulation on the camera.
The coatings are slightly magenta.
I'd like to see how this does in good daylight.
It is much better than it looked in the shop, after a good cleaning.

I had Zenmarket bundle me four lenses. Arrived today.

SMC Pentax-A 35-70 3.5-4.5 turns out to be broken. Rear element is rattling in the body and aperture lever is bent. Hopefully I can fix it.






SMC Pentax-A 35-70mm 1:4
This one looks OK but not to sure about the heavy wear on the front of the focus ring. It may be decentered. I also wonder what the lenscap for this one is. A regular 49mm won't fit (nor will a 49mm filter).





SMC Pentax-m 28mm 1:2.8

A pretty common one but didn't have it yet. It looks fine even though sold a junk. There was fungus but just on the skylight filter on the other lens that was sold with it (next one after this).




The last one came with the 28mm so I had no choice but to buy it too. Front element bit dirty but have since cleaned it. I think it won't reach infinity because it seems to extend further than the copy I already own, but perhaps Pentax changed it a bit.
