Ernst Leitz Wetzlar Summar f=5cm 1:2

E Mount, Leica M39, Lens Reviews

On monday I took my chance and had a nice camera walk in the sunshine of Heidelberg. To challenge myself I took a lens with me that I barely use. The Ernst Leitz Wetzlar Summar f=5cm 1:2 (Leica Summar 50mm f2).

The lens

The little Ernst Leitz Wetzlar Summar was built between 1932 and 1939 and is still yet a really sharp and superb lens. Its made out of six elements and has six aperture blades.

Optical Quality

Even on modern 42 megapixel camera the lens is really usable. When its open at f2 its sharp in the middle with a slight vignetting and really soft corners. When you stop it down it becomes a really really sharp lens.

The bokeh is bubbly and swirly really similar to the Helios 44 lenses.

My M42 Lenses on the Fotodiox Pronto Autofocus Adapter

E Mount, Fotodiox Pronto, M42

In this article its all about the compability of my M42 lenses to the Fotodiox Pronto (Techart PRO AF) adapter.

As the autofocus works with all lenses, better when its brigt worse when its darker, this article is about if the 4,5mm focusway is enough. (More Info about the adapter)

The test was done with this setup:

Sony Alpha 7RII + Fotodiox Pronto + Fotodiox M42 auf Leica M + M42 Lens

Important facts, Tipps and Tricks, E Mount

Hello everyone. This is my first ever blog post on my own page about vintage lenses and adapting them to modern mirrorless cameras.

I started this project out of my own love for vintage cameras. About 3 years ago I found a mystical box with various old Exakta EXA mount lenses inside it. At this time I used a a Sony Alpha 77II as my main camera. Adapting the old lenses coming with EXA Mount to my Sony A Mount translucent mirror camera was quite easy. There are several adapters but they all need an compensating glas element.

Because of the loss of quality that my cheap far east adapter gave me I soon decided to move on to a Sony Alpha 6000 my camera in combination with adapters and vintage lenses.

The good thing about the Alpha 6000 is the really short flange focal distance of the Sony E Mount system. This gives the adapter enough space to be built without a compensating glas element.

After a while of being active in several Facebook and Instagram communitys I decided to buy some more old objectives like the legendary Meyer Optik Görlitz Trioplan 50 and 100. Up to today I own over 40 lenses which will be reviewed in this blog. The list of lenses can be found here.

After posting some of the really cool photos I took with these lenses the first questions began to pop up. People asked me about the lenses, the technique, the camera, the adapters and it happened more and more often. So I finally decided to start this project and spread the love and addiction for vintage lenses.

On this page, me and some guest authors will tell you everything what we know about all the different lenses, adapters and camera systems. If you have any questions feel free to comment or email me.
