Yes, if it was me, I'd want autofocus or a rangefinder. It doesn't really matter how good the lens is if everything is out of focus. Fine if you are shooting landscapes, or daylight outdoor scenes where you can zone focus or 'hyperfocal' focus. But portraits, or anything in lower light, or closer up, nope. The mju is good and cheap.

If it didn't have to be quite as cheap, my own personal favourite is the Rollei AFM/Fuji Klasse. Good size, lots of manual control, excellent lens, good flare resistance, and (in my experience) very accurate metering.
