Canon EF-S 35mm f2.8 IS STM Macro coming soon.
Quote:Only thing I didn't like is STM and focus by wire, this is simply not practical for macro.

You do need manual focus and you do need the focus distance written on the lens.

Dunno why they opted for focus by wire on a macro lens
Focus by wire works well on some STM lenses (in my experience the EF-S 10-18mm and EF-M 18-55mm work well, 22mm f2 a bit less so). So as long as it works responsively, it should be ok for macro.

I have NO idea why you would need a focus distance scale written on the lens for macro photography, though. You ALWAYS check focus in the OVF or live view LCD, so no need ever for a distance scale.


For silent, accurate and fast live view action, they opt for STM. Logical choice. STM lenses have focus by wire, because they lack the gearing to make AF/M switching impossible.
