Ok, I've been lurking in dark rooms to test out the AF in low light. Low enough to give me some low shutter speed issues with the 27 @ 2.8. Nothing scientific here but it seems much faster that the XT10. It's certainly faster than my Pen F which can really hunt in low light.Great shot of the Univex. You've had the X-T20 only an hour or so... but any obvious autofocus improvements so far?
