A translation of the link is below in bold for those who do not speak or read German. Something (a little) is lost when using Google Translate but you should all get the gist of it. The soligor/Hanimex Vivitar lens names were almost all made in the same factory. As there were several factories involved it is almost impossible to say which one. Kiron/Cosina/and possibly Sigma were involved somewhere along the line. Why I asked about the green line around the lens was that Hanimex marketed a range of quite decent lenses around about 1978-82 which were all wider than normal aperture with the green ring and they did come from Kiron. (I can say this because the name of the factory was inside the box and on the instruction sheet).
Since we are just at Soligor lenses, I want to introduce another zoom lens, which accompanied me for a long time.
Here are the facts:
Manufacturer: Soligor
Rotary zoom with Macrofunction
Weight: 405 grams
Filter: 58 mm
Length: smallest 89 mm, largest 115 mm
largest diameter (on the front grip rubber): 65 mm
Aperture: 2.5-22 in whole steps
Minimum focusing distance: 0.7 m
solid metalwork, painted, pleasant handling
built-in lens hood
Lenses / Groups: unknown, did not have to disassemble yet
8 lamellae in stop sign form
Shutter switch Auto / Manual
The lens is consistently the brightest zoom in this focal length range for M42 (but was also produced for Y / C, OM and others) and also a true macro.
In the (BAS) tests the Soligor always did very good to excellent, sometime in the middle of the nineties I bought it in an excellent condition, I think for twenty marks. It would have to be one of the last lenses made by Soligor.
The lens was later also sold under the labels Unitor, Tefnon and Magnum Optics (Access).
The reviews did not disappoint. The lens is already sharp at open aperture, the best performance is achieved at 5.6. At 35mm, the quality is a bit soft, you can see that the designers have already set the focus of the lens calculation here on macro. But from a tiny turn that looks neat again in normal shots.
Since I had hardly any problems on film with field curvature, distortion and aberration, I did not disappoint the results at the EOS.
The macro function is, as usual at that time, achieved with a rotary ring (infinitely variable), which removes the entire lens design like a bellows device from the camera, good for the optical quality.
The magnification of the Soligor is from 1: 8 to 1: 2,7 as a maximum. The aperture is not changed mechanically. From 2.5 to 3.5, only the falling light intensity decreases.
The built-in sun visor can be pushed out only about 1cm, which is sufficient for most conditions, but in light from the front you should then use another geli, the lens is a little flare susceptible.
The lens brings a bit cooler colors, but that never bothered me.
The only small disadvantage is actually the focus setting.
With not even a quarter turn you are from 0.7m to infinity. So you need either a good eye and a lot of experience or as a spectacle wearer I need a search light.
Or just liveview. But even without it actually goes, if one has gotten used to it (all photos shown here are focused only with the eye, my viewfinder for the EOS can be expected).
And I can not expect any photos in a test, my scanner is eleven years old .. (maybe I should buy a new one)
Conclusion:
A very good all round lens with very good macro properties, very compact and relatively light for a metal construction.
If you can take only one (for whatever reason) and still be prepared for as many eventualities Soligor is a very good choice.
