Comparing Sony LA-EA2 and Sony LA-EA4

Today I received my Sony adapter LA-EA4 and did a quick comparison with the older version LA-EA2. Both adapters add a translucent mirror to a NEX series camera and are built for the Alpha lens lineup. But the newer version LA-EA4 can also be used on the two new mirrorless full-frame sensor cameras with interchangeable lenses from Sony (the Sony A7r and Sony A7). The older version is only suitable for the Sony NEX series with APS-C sized sensors.

There is only a slight difference in weight (Sony LA-EA2 is 200g, the Sony LA-EA4 is 160g). Another difference is of course the size of the translucent mirror. The difference can easily be seen in the product shots. The speed of the autofocus seems to be the same (but I did no scientific test on that).

Both adapters work with the old “screwdriver” type autofocus lenses (Minolta 28-70/2.8 tested) and with the new SSM type autofocus lenses (Sony 70-200/2.8 tested). I did not test any SAM lenses. Both adapters work with my NEX-5 and also with the NEX-7.

With the NEX-5 I could only select a specific autofocus point with the old adapter. With the NEX-7 I could select a specific autofocus point with both adapters.

At Joseph Fraunhofer’s Tomb

This panorama is a tribute to Joseph von Fraunhofer (* March 6, 1787 – † June 7, 1826) a German physicist and optician. He was born in Straubing and died in Munich. This panorama shows his tomb in Munich. I shot this panorama at his tomb almost eight years ago!

From the 85m high tower of Munich’s town hall you have a great view over the city centre. When you’re lucky you can even see the Bavarian alps in the distance. The tower can easily be ascend via elevator.

Reprojected Bavarian Ministry of the Interior Courtyard

In 2012 the German Unity Day has been celebrated in Munich. The celebrations include a showcase of the German federated states (Bundesländer) and also other institutions like the parties of the Bavarian parliament. In the courtyard of the Bavarian Ministry of the Interior was an exhibition showing the many task of the ministry. This image shows a reprojected version of this panorama I made in the courtyard.

Cornerfix profiles for ultra wide Voigtlaender lenses on Sony NEX-5 and NEX-7

In a previous article I already described how to post-process images which were taken with ultra wide legacy lenses on a Sony NEX in order to eliminate the magenta cast in the corners. I use the free software cornerfix (which is available for Mac and PC).

In order to get the best results, you should create your own lens profiles. Therefore you can follow these instructions. I recommend a flat field reference file which is based on a picture through a matted glass panel.

But as you may not have such a glass panel at hands you can also download one of my profiles and give it a try.

If the profiles work for you, then please leave a comment or send a note.

Hintere Entschenalpe

The name of the alp you see here roughly translates to “Hindmost Colossus Alp”. It is found in the Retterschwang valley near Bad Hindelang. Cycling from Bad Hindelang brings you from 800m to the alp at 1451m in about 10km distance. You should use a mountain bike with the appropriate gears!

Tilt experiments with Kipon Tilt adapter for Nikon lenses on Sony NEX cameras

Kipon manufactures an adapter which enables you to mount any lens with a Nikon F-mount to your Sony NEX camera. Additionally the adapter can be tilted in any direction. Tilting in this context means, that the lens is pivoted out of the optical axis of the lens.

The two following images illustrate this concept. In the first image the lens was tilted to the right (from the photographers point of view). In the second image the lens was tilted to the left (from the photographers point of view).

You can use a tilted lens to orient the plane of focus of your optical system in special ways. Normally you use a tilting lens so that the plane of focus is oriented in a way which maximizes the visually sharp areas of your image. Theodor Scheimpflug was the first person who described these facts and therefore the priciple is called the Scheimpflug principle.

But in the following example I tilted the lens in order to orient the plane of focus in a way which minimized the sharp areas of the image. As this looks nearly identical to a very shallow depth of field, the observer mostly gets the impression, that he is only looking on a photographed mock-up of a landscape rather than a real landscape.

In order to get this image, the lens was tilted and the camera was pointed down. Back at home, the vertical lines of the buildings were brought back to vertical alignment. In other words I tilted in the real world and shifted in the digital world…

Cross on Summit of Mount Hirschberg

North of Bad Hindelang arises the Hirschberg. It is a mountain, that is 1500m high. Near the cross is a beautiful viewpoint to the valley of Bad Hindelang, Bad Oberforf and also towards Oberjoch.
