AstrHori MF 9mm f/2.8 9mm
The 9mm f/2.8 lens (13.5mm full-frame equivalent) uses one aspherical and two extra-low dispersion elements to deliver sharp ultra-wide imaging in a compact 306g body. Its manual focus operation and retro metal build with a built-in petal hood offer a tactile, deliberate shooting experience distinct from autofocus options. This lens suits landscape photographers on Sony APS-C cameras needing the expansive 13.5mm equivalent view, but its low travel score reflects limited versatility for all-around use.
