Here's a recent one of mine. Contax G2

The two laws of autofocus, according to Tompas:

1. Autofocus is good when you don't need it.
2. Manual focus is good when you need autofocus.
 
Very common with autofocus, especially for folks who switch cameras.

One solution is only use autofocus in cameras with Face Detection.

The other is understand how your autofocus works (as referenced above), or now how to preset the manual focus.
 
I would say "disaster of not knowing your camera"
Autofocus is not a wizard, just a tool

Gosh you guys are hard! I normally nail the autofocus on the g2 and this was an attempt at a light hearted ribbing of getting it wrong, inviting more of the same. I guess le vrai rdu is perfect and all shots are keepers!
 
Of course not but I had a G2 and talking of disaster when the camera has only a central focus point..........

Not sure I understand your point, but just for clarity, I (thought I) focused on the girl on the right and reframed (badly). Obviously I missed and actually focus on the lady with the rucksac.

Anyway, I looked at your flickr and recalled reading a previous post of yours about your fishing trip - those are not far from perfect! :)
 
One thing I don't like with auto focus cameras is ones that by default, lock the AE with a half shutter press along with the AF ... it's not smart at all!

Yes. Luckily this is configurable by menu or switch on both my autofocus cameras (K-x, F4); it probably is on most cameras?
 
i had the same problem when i first got my G2. Wasted many a frame i did... i had seemingly more difficulty with the "half-shutter to focus and recompose" on the G2 than the 35Ti and GR1, though the latter 2 are compacts so probably not a far comparison?

for me this was actually intended though :)
 
On a slow day, perhaps practice autofocusing at various subject distances (and confirming via the distance readout) to get a feel for how parallax affects where the autofocus actually focuses in relationship to the viewfinder mark? :)
