TTartisan AF 17mm f/1.8 Air & 7.5mm f/2 Fisheye Land Under $150

If you shoot Fuji X or Sony APS-C and want a fast wide prime with autofocus without spending Sigma Art money, TTartisan's new 17mm f/1.8 Air at $148 deserves a look — AF under $150 in this focal length is genuinely hard to find. The 7.5mm fisheye silver edition is purely cosmetic over the existing version, so skip it unless you're buying new anyway.
