Re: Common Frustration.....Face Detection Help to alleviate the AF inconsistancy

Sadly, an all too common experience for most of us here soon or later.

My NEX C3 (no PDAF) will sometimes missed shot that is right in front of it. Its a source of my constant annoyance with NEX. I found these steps helps:

1. Take multiple shots of the same scene (machine gun approach), then threw away the OOF

2. Sony Face Detection (and Smile Shutter) works surprisingly well

It does, but sometimes the Nex cameras will STILL stubbornly focus on the background, if right around the head is a high-contrast background -- strong lines, a bush with sharp-edged leaves, etc.

They help to alleviate my NEX AF frustration, but I got tired of inconsistent result and sold my NEX. The new Sony A6000 AF seem very promising. Unlike NEX 5R with its exaggerated PDAF claim, the new A6000 seem to have nailed it on the AF. I'm looking forward to A6000 with cautious optimism.

The PDAF adds speed more than accuracy, I think, but I do feel that my Nex-6 is better than my Nex-5, for whatever reason.  Occasionally I need to either half-press again or retake the shot, but it seems better.
