comment:This lens is one of my workhorses and renders very good IQ with modest distortion even at 12mm for this type of lens. The flare control, even at 12mm is very good but is to be expected (this is a very bulbous lens) - after shooting hundreds of images at 12mm I have only had this problem on a handful of shots. I am a bit nervous using it because of the inability to give it protection via a filter coupled with its shape which is conducive to attracting dust and debris.

I am now using this (as of May 2019) on an a900 infrared converted camera. I still find this to be wonderful lens with, given its wide nature, only very modest softening at the edges on full frame.
