This is the blog of the PanoTwins
This year ended with a photographic experiment. Each of us used two sparklers to write 2013 in the air.
See you next year on our blog…

This panorama was stitched from six images in landscape orientation. The size of the final image is 5.875 pixel x 11.127 pixel. It shows the construction site of the European Central Bank at dusk.

I took this panorama with a new double monopod construction. From the distance it is similar to the one you see here. This is also the first night shot with the new Sony ILCE-7 and the Walimex 8mm/f2.8 fisheye lens. I’m quite pleased with the results!

This is the first pole panorama I shot with the Sony ILCE-7 camera and the Walimex Pro 8mm fisheye lens. In order to use this lens on the camera I had to remove the sun shade. However this was quite easy, as it is made from plastic. I was able to remove it using a small side cutter and a cardboard cutter.

In a recent article I described, why the E-mount of the Sony ILCE-7 is so interesting for people with legacy lenses and how to configure your Sony ILCE-7 to assist when taking pictures with these lenses. In another article I also described, how to get rid of the magenta cast in the corners when you are using ultra wide lenses on the cameras which incorporate the Sony E-mount.
And here is another example of a legacy ultra wide lens adapted to the E-mount.
Originally this lens was constructed for the M39 screw-mount of early Leica cameras. So you could either use an Novoflex NEX/LEI adapter or you use an M-Bayonet Adapter and the Novoflex NEX/LEM adapter. Depending on your other lenses one of this options should suit your needs. Personally I use the second option and I don’t have any problems while focusing.
If you’d like to read an intensive review of the lens then take a look at this page.
The lens mount of the Sony NEX camera system is called E-mount. The E stands for Eighteen, as the flange focal distance of the Sony NEX camera series is exactly eighteen millimeters. Most interchangeable lens systems use a longer flange focal distance and therefore you can adapt nearly every available lens to the E-mount of the Sony NEX camera system.
In this case I used the NEX/LEM adapter from Novoflex to adapt an Voigtländer Ultra Wide Heliar 12mm/5.6 to a Sony A7 (ILCE-7). As this camera incorporates a full frame sensor this setup equals to a focal length of 12mm.
You must be aware that this combination only allows manual control. But the Sony A7 (ILCE-7) camera assists in the use of manual lenses if the camera is proper configured:
Switch your camera to A- Mode (aperture priority) and use the Focus Magnifier function to get a perfectly sharp picture even when shooting a fast lens wide open. The default configuration of the camera assigns the Focus Magnifier function to button C1 (Custom Button 1). You can reassign the function using Menu → Custom Settings (gear icon) → 6 → Custom Key Settings.
