This panorama was stitched from six images in landscape orientation. The resulting panorama is 10800 x 5585 pixels. Despite the fact that it was taken through a tinted window, I’m quite pleased with the final result.

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.
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.

- Sony NEX-7 with Leica Summicron-M 35mm/2 (Asph.) @ 5.6
- Sony NEX-7 with Leica Summicron-M 35mm/2 (Asph.) @ 8.0
- Sony NEX-7 with Leica Summicron-M 35mm/2 (Asph.) @ 11.0
- Sony NEX-7 with Leica Summicron-M 35mm/2 (Asph.) @ 16.0
If the profiles work for you, then please leave a comment or send a note.
I also created some profiles for the Voigtländer Ultra Wide Heliar 12mm/5.6 and the Voigtländer Super Wide Heliar 15mm/4.5 on the Sony NEX-5 and the Sony NEX-7.
Here is an example of an uncorrected shot with the Sony NEX-7 and the Leica Summicron 35mm/2 @ f7.1.
This is the same image but additionally corrected with cornerfix and this profile (5.6).

We hadn’t visited the mountain Herðubreið but we went back to Germany with the plane Herðubreið 😉
A short stop at Strandarkirkja and the blue lagoon before we spent our final night in Kevlavík.
Today we visited a lava field of the vulcano Hekla and we had a great dinner 😉
