Sony NEX5-N and lens Voigtlander Super Wide Heliar 15mm f/4.5 Aspherical. Taken hand held at ISO 800, f/4.5, 1/1250s.White Balance was set on "Cloudy".
It was revealed in a recent test done by Steve Huff (see link below for full credit) that the SONY NEX7 produces an awful magenta color cast when wide angle lenses are used, like on the Leica M9. Unlike the M9 though the NEX7 does not have any in-camera processing to get rid of the magenta casts. He also tested the NEX5-N and stated that it behaved very well with the Voigtlander 15mm f/4.5 which was used to compare the two Sony bodies.
Well, after testing this very lens (Voigtlander Super Heliar 15mm f/4.5 Aspherical) - thanks to Tomasz a flickr member who kindly lent me his lens to try it - I have experienced the following:
- the magenta cast is not eliminated at all on the NEX5-N as shown on the picture above. It exists on the extreme left and right side of the photo and only in extreme contrast situation.
- the photo I posted is the worst case of magenta cast I could witness.
On the photo below taken the very same day with same camera/lens combination, the magenta cast is less visible because of the lack of monotonous tone to reveal it and the presence of lens vignetting that helps. It is still visible if you pay attention on the branches of the tall tree at the extreme left:
