great wide ...

... I have this objective for some time and wanted to like to write my experiences with it down. The resolution is absolutely great, experienced almost no longer does the lens at 12mm focal length little, for a super wide, at 24mm. focus is quickly and safely possible. Furthermore, the possibility is to intervene directly into fokossieren really great.
now the small flaws. Unfortunately it generates in the range of 12mm green and purple seams at very high-contrast edges. In RAW mode, it is no problem to retouch away, shooting in JPEG, it may lead to problems. also the focus could be a little quieter. Otherwise, a great lens!
