Carl Zeiss Jena Flektogon 35mm f2.8 (Part 1)

like a child with a new toy! I mounted my new lens to the (m42-to-AMount) adapter and is about to embarge on a journey involving a fifty years old lens.  The glass is a Carl Zeiss Jena Flektogon in such a perfect condition that is is practically impossible to judge its age. It is masterly restored by Maziar Moarefi, and stands like a jewel with its bright chrome barrel (if you are interested in how then I think the best advice is “dont” this lens seems really complex and not a place to start). There is a luxury aura to it, which is making it painfully obvious that this is a gem that should be treasured for the next many years. The build quality of this piece of glass simply puts it in a league of it own. All metal and every moving part feels great. The aperture ring moves freely, and due to the brillant state of my edition it has very little resistance to it.

This version is known to have a really pleasing bokeh, I am ecstatic to see if I can produce some of the same results i see on the web with my edition. After all who does not love a very creamy, delicious bokeh. The accurate colour rendition of this lens, which many has come to know as the Carl Zeiss colour, should excel in the way that they should come out perfectly ‘real’ and gorgeous in an understated way. At the same time the contrast is known to be excellent.

Mechanically, this lens has a 9 aperture blades, which is preferable to the newer edition with only 6 blades. The blades are rounded and are superior to all, while allows the blade to resemble something that is closer to a perfect circle, giving the more perfect bokeh. The aperture goes from f/16 to f/2.8, smoothly, and without click stops. I guess that is something I need to get use to, as I am unconsciously counting the stops in order to know where in the aperture range I am. The focus is amazing, I tried it yesterday, very long walk on the dial, allowing for very accurate focus. The near limit allows this lens to be sharp from 0,36m (1,2ft) to Infinit.

It is difficult to describe the great experience this lens gives on my camera. There is little doubt that this is an absolutely stunning lens.  I hope you will follow my adventure with this lens…

Take me to Part Two

New light in some old glass

This is a guest article written by Daniel Ellwanger, a young German photographer.

A little while ago I visited my grandparents in their house. When we ended the very delicious meal I went into their basement to get me a German beer. I looked into the glass cabinet I could not believe what was in there.

What I saw was a pile of old cameras and lenses. Some old Pentax, a couple of old Voigtländers and some Exakta cameras in great condition. Most of the lenses I found in the cabinet were made for Exakta-Mount. Because of this fact I decided to ask my grandpa for the permission to use these Exakte lenses. As soon as he said yes I immediately opened Amazon and ordered a Photodiox A-Mount to Exakta adapter.

Some days later I went back to their house to pick up the lenses that he was willing to borrow to me. This is a list of all the Exakta lenses which I am going to test in the next couple of weeks.

The Meyer Optik Görlitz Primoplan 58mm f1,9

In this first blog entry I am will introduce you the Meyer Optik Görlitz lens named Primoplan. With its focal lengths of 58mm and a maximum aperture of 1,9 it has some really unusual specs. The lens was manufactured between 1952 and 1959 in East Germany.

Cam and lens



These are some test shots I took with the Primoplan 58mm at f1,9. The camera I use is a Sony A77II and the adapter of choice is a Photodiox Exakta to A-Mount adapter.





In my opinion the bokeh of this tiny piece of German engineering is one of the most beautiful bokehs I’ve ever seen. The soap-bubble look of the Meyer-Optik Görlitz lenses is really unique and famous. This is also the for a Kickstarter project produce a reworked Meyer Optik lens for DSLR and mirrorless cameras[1].


I hope you liked my first blog entry. Special thanks to Jorgen Guldmann who features me in his Blog. If you have any feedback please feel free to tell me whats good and whats bad.
