Okay, a few more to show the lens traits. All are in-cam jpegs shot with AWB, auto ISO and full frame A7r, downsized for web. First is a shot of gray pavement showing both falloff and color shifts, no other processing:
Next is a common subject that shows distortion and color shift as well as fall-off. I did add a touch of local contrast to the in-cam jpeg, but net color is out of cam:
Final is one I worked a bit. Cropped square, converted to mono, added some more vignette, added noise and a bit of halation glow for effect:
I am liking this lens a lot, having some fun with it for sure -- thanks Mike!!!
