Pentax K1 + Laowa 12/2.8
Its hard to imagine that just a few years ago, one would laugh off at the prospect that a China company would be making lenses that might challenge the traditional Japanese and German makers.
I too laughed at the lens when I first read about the brands.
Laowa, I made a pun with the name and called it "Lao Ya", in local dialect meaning lousy.
But looks like I got to take my word back on the lens.
12mm, but smaller than my Samyang 14.
Lower distortion
Seemly better flare tolerance than the Samyang and Irix.
Better edges than my Voigtlander 12/4.5 II
Large enough image circle for Pentax sensor shift composition adjustment and also as a 1.5x crop shift lens with a Kipon adapter on my A7.
