All but the last three photos were taken with the Loxia 21mm lens on the A7S. This lens has proven to be sharp wide open and corner to corner (of course it gets even sharper when it’s stopped down). The colors are excellent and the lens does not suffer from chromatic aberration or other faults. It is a fantastic lens for any photos that conform to a 21mm focal length. I highly recommend it to any A7-type camera users.
The final three photos in the group above were taken with the Voigtlander 10mm. This lens cannot compare to the Loxia 21mm with respect to corner sharpness, or flare resistance or chromatic aberration. This is not to say that it is bad in these respects. On the contrary for an unbelievably wide 10mm focal length it’s actually amazingly good, just not in the same league with the Loxia. What it does excel at is providing the ability to juxtapose a foreground and background in extremely creative ways that only ultra wide angles can provide. And so if you need that type of composition I wholeheartedly recomment this Voigtlander (or the 12mm version too).
