just a couple of things
I like the 12mm field of view but the 16mm looks more natural without the obvious "distortions" of that focal length.
Any lens from 12 to 75mm can be used for blogging but I think 16mm is a very good compromise not to get the camera too far with a natural look.
F/1.4 looks perfectly usable with very good out of focus zones, color rendering is great.
Was your profile picture made with the 12mm or the 7.5mm ?
