Sigma mogging Canon, Nikon, and Sony with a 500mm f/5.6 lens that looks great with the Snoy a1 (50mp). Yeah, it won't look very goos with the 2x teleconverter on 60mp Leicas, but this lens will rape the used market.

>native to mirrorless
>lighter than nearly everyone
>lose only 1 stop, and macro
>holds up to everything <$6.5k used
why the fuck would you buy a used tele, for birds and wildlife anymore? No fucking reason.

SELL NIKON MIRRORLESS BODIES
SELL CANON MIRRORLESS BODIES
HURRY!!!! THEY ARE WORTHLESS NOW!!!!
