+ Pleasant feel and operation
+ Quality workmanship / materials
+ Very quick to deploy, faster AF and quiet!
+/- Aperture: particularly in the interior has to be right the light, otherwise colors are mapped before slightly distorted. Since a longer exposure time is of little use.
-for professional architectural photography, it is only conditionally suitable. For that I can deduct no star.
My conclusion: It is neither a super macro lens, even a tele miracle. But my expectations were exceeded in almost all areas. Assuming you have mastered his camera, you can do well with this lens moody and almost professional recordings. If you want more, just needs to invest more, unfortunately. This is true only for people who want more than the 'amateur photography' addition.
