Can a 12mm lens (18mm equivalent on full frame) be used successfully for portraiture? I made the attempt and achieved some results that I like.
Nine Retina-grade examples are shown, each with both color and black and white renditions. The Touit 12/2.8 makes an exceptional lens for black and white conversions.
To my eye, the Zeiss Touit 12mm f/2.8 might be the best-performing 18mm (equiv) lens that I have yet seen, offering an impressive combination of sharpness, contrast, bokeh, and color correction.
And so I will say this: if you’re a Sony NEX shooter, this is a must have lens for wide angle work. Presumably the same applies to Fuji X, but I have not yet tested on the Fuji X-Pro1 or X-E1.
