What 85mm at f/1.8 actually gives you
85mm is the classic portrait range — long enough to compress features flatteringly without forcing you across the room.
f/1.8 is fast enough to keep shutter speeds up in poor light and to separate a subject from its background clearly.
Size and filters
At 490g (1.08 lb) it sits in the middle for handling: substantial enough to feel planted, light enough not to dominate the kit.
Filters are 67mm — worth checking against what you already own, since polarisers and ND filters at this size are reusable across any other lens sharing the thread.
Autofocus and stabilisation
Autofocus is driven by an STM motor.
There is no optical stabilisation in the lens, so handheld steadiness depends on the body having IBIS, or on keeping the shutter speed up.
