flare control: 2
|ownership:||I own this lens|
|compared to:||CZ 16-35, minolta 20mm f/2.8.|
|positive:||12mm orthoscopic, full frame. No other lens does this.|
|comment:||This is a weird lens for these ultra-wide effects.|
IQ is good and great around f/8-f/11. Wide opened, it vignettes like crazy.
I guess that the question is "how does it compare to the CZ?". This is the wrong question, they are lenses for very different uses. in a nutshell: the CZ has better micro-contrast and way better colors. The CZ can be used in dim light. This lens is much, much wider. Don't be fooled: 4mm is a lot of difference.
Colors are poor, noticeably yellow. Nothing which can't be corrected in post though.
Flare control is poor, you get pink blobs somewhere in the frame.
Distortion control is impressive.
You can't use any filter in front of this lens.
