Brazilian photographer Charles Oliveira recently put the Mitakon Speedmaster 85mm f/1.2 lensthrough its paces using his Nikon D600. Announced back in 2015, this is a Chinese lens that offers 85mm f/1.2 at a relatively affordable price of $799.
Canon’s 85mm f/1.2 lens currently costs $1,849. Nikon doesn’t even offer an equivalent lens: the closest you can get is the $1,600 Nikkor 85mm f/1.4.
To test out the shallow depth of field and bokeh quality of the Mitakon Speedmaster 85mm f/1.2, Oliveira photographed his girlfriend, Gaby, in the historic Brazilian city of Ouro Preto.
