TTArtisan – the Chinese maker of small, oddly heavy, oddly cheap, and typically wide-aperture lenses – bowed (Chinese) three new offerings for the Sony E-mount lineup.

The manual focus and manual aperture lenses have their optical formulas graphically represented on the barrel, which is interesting, if not useful.

Fuji FX, M43 and Canon M mounts will also be supported.

The lenses will be available on the brand’s Amazon store. The 35mm is already up and costs $73. The price of the others is yet unannounced.
