I've been shooting like this since I got the camera just two weeks ago, and it's really becoming second nature.
Another hint:
Depending on your manual lens, the KX will meter inconsistently. It's just the nature of the beast--old stuff on state of the art stuff. I've had pretty good luck/calibration (so far) with my old manual lenses, but my Tak 50 1.4 underexposes a little. Some people experience a major shift, and also, it's not necessarily consistent along all apertures. Like, 1.4 is fine, 2.8 is great, but from 4 to 22, you may have to go over a stop.
For now, I just monitor this by looking at the review in the LCD--which is NOT a great indicator of anything, but it's better than nothing. So after I hit the shutter and notice it's a little under, I just open a little and shoot without going to green button again.
I doubt I'll be able to catch hummingbirds like this, but maybe I'll get lucky.
