Mine is the Konica Hexanon AR, f3.5 - f16 Looked like 5 elements I think UPDATE same as Ians' in this thread so ?7 elements - 3 in the front unit and two behind. I love the sharpness and smooth bokeh, found the contrast tending to dull (but I did have to clean off fungus) and colours/saturation required a boost. Lumix G1 from RAW.

That lens does produce nice images.


yes, although version before this one, last one with 7 lenses in 7 groups is supposed to be better


Yes, the 7/7 Hexanon lens is better than the 5/5. But if your lens' smallest aperture is f16, you have the 7/7 model. There is only one 28mm Hexanon with 5/5 construction and its smallest aperture is f22. It is the compact version introduced in late 1976. The only way you could have a Konica 28/3.5 lens with 5/5 construction and a smallest aperture of f16 is if it was the Hexar (made from early 1975 to late 1977).
Very nice photos BTW. Smile

Thats not a bad pic... don't get down on yourself now Wink I have seen worse from people who call themselves pro's

Hey, just wondering off hand, how do I tell the difference between the 5 and the 7 element version? and then how do I tell the difference between the different 7 element versions to know if It was the "last" of the & elements.

Just wondering.

Great lens, I need to get one to compare to my 28 1.8 Hexanon.


Hexanon are nice lenses . I find nevertheless their aperture ring rough.
May I ask you question ?
How your Rokkors 50/1.4 compare to your Pentax M 50/1.4 ?

There is much confusion about Hexanon 28/3.5 lenses. Here is a list of them all:

The 7/7 model comes in 4 versions:
High-gloss black finish with aluminum ring (1965-1967)
Satin black finish with aluminum ring (1967-1970)
Satin black finish, entirely black (1970-late 1973)
Satin black finish, entirely black, rubber covered focusing ring (early 1973-late 1977).

The smallest aperture of all 7/7 versions is f16. They are, optically speaking, the same lens. They differ only in appearance, barrel style, and coatings. The first three versions have 'EE' on the aperture ring, while the last version has 'AE' on the aperture ring (this bit of trivia for those who give meaning to this detail).

The 5/5 model comes in only one version:
Satin black finish, compact version, rubber covered focusing ring (early 1978-mid 1987). It's smallest aperture is f22 and it also has 'AE' o the aperture ring.

There is also the Hexar, often mistaken for a Hexanon. It can easily be recognized from a distance because of its relatively recessed front element and its thin focusing ring. It has a 5/5 construction, a smallest aperture of f16 and was made from early 1975 to early 1978. The Hexar also has 'AE' on the aperture ring.

All of the above are automatic aperture lenses. There is also a quite rare Hexanon 28/3.5 preset lens with a smallest aperture of f22 (15 aperture blades!) and a 58mm filter thread. It has a 7/6 construction and was made from 1965 to about 1969.

That's 7 in all. If there are any others, in 35 years of shooting with Hexanon lenses, I have never heard of one or seen one in Konica literature.

PS:
Please note that whether a Hexanon lens has EE or AR on its aperture ring has NOTHING to do with that lens' version. The letters EE or AR on that lens MAY correspond to a lens variation in the case of one particular lens, but for the great majority it DOESN'T and is just a coincidence.

Thank you Renato, i have taken that view with a number of lenses, different lighting, see what seems to work..

My lens is all black, all metal. Serial number of my lens is 7178xxxx does that indicate 1971 as year of origin?

One more (cropped and resized):

At f5.6 - f8 this lens is tack sharp, with no sign of fringing or CA, and even though the lighting was flat, the 3D look of the stone cat is great.

Thanks, konicamera, for reaffirming that. What you stated here (f16 is a "tell" for 7/7) is my current understanding of this lens. But some of the earlier statements on this thread were casting doubt until you posted.

Hi WolverineX,
I loved your picture for the sharpness, color and all. So, I moved from Sony Nex to bought an OMD EM10 for easy to learned form you. But today i tried on many for the Konica Hexanon 85 1.8 and even 28 3.5 but the picture look like not so good then you, although I set the aperture f5.6 for Konica Hexanon AE 28 f3.5 lens and f11 for the 85 1.8.
So can you give me a tip to adjust the camera to reach the great shot like yours. Because I also newbie on OMD.

Thank you so much.

The below picture I'm taken with Konica Hexanon 28 f3.5 on OMD EM10, at aperture f5.6 but look not so good: The flower is not so clear with any layer. I like the first picture about the flower of yours.

Yes, thanks for your advises. Actually the photo was direct from the camera. I will try to learn how to optimize my camera on web.
The lens is in good condition.

Thanks again...WolverineX
