“ I hqve taken notice that in cameras, extraordinary sensors help to focus automatically.
These sensors involving some video cameras change in in the area oof contrast, while others
ork with a beam associated with infra-red (IR) light,
specifically in low lumination. Higher specs cameras from time to time use a mix oof
both programs and couod have Face Priority AF where the dsr camera can 'See' a face whle keeping focused only upon that.
Thank you for sharing your ideas oon this site. ”
