Ok, i am obsessed with focus today. My Canon 40D used with it's kit lens 17-85mm.
It is not the optimum lighting condition for photography.
In the following photo, mid-day sun in UK. Not the recommended time for photography.
I lock the focus [centre AF point used] on the pupil the subject, & prior to I release the shutter button my subject move the eyes and look back into the camera. I do not seem to like the sharpness.
Should I use a tripod or larger aperture 11 or higher to get the sharpness I am after?? I wonder. or invest in an Canon L lens?
I was so much thinking of the focus: I failed to realise my metadata;
Yes Mine here was F/16 1/5 ISO 100 Hand held. My daughter would not sit me to take her photo just tried to capture her portrait completely immersed in my thoughts about "Focus lock"
