What does it mean to have "315 points of phase-detection AF"?
Apr 21, 2019,15:19 PM
I presume that it's better than having 300 but not better than 400 points, and better than out-of-phase, or no-phase detection. But does the scale of point counts go from 1 to infinity? The spec doesn't say.
Does it mean the camera will focus on a fast-moving target?
Or on something that's fluttering in the wind
Or on multiple points simultaneously?
Or in the dark?
Or on a diffused, soft target?
Am I in over my head? Or can I just "trust the camera" to do the thinking for me while I continue to practice?

PS - one source I read said "The topic of autofocus can get quite complex. Understanding it fully requires a depth of technological understanding that most photographers (myself included) don’t have. This article is a simplification of the basic principles. It should help you understand how different autofocus systems work, and what the pros and cons of each type are. If you have any more questions ... uh, umm."

Challenging due to light shifting and lizard moving about. Taken from about 6 feet away - I was coming up the stairs and saw him in time to stop and adjust up/down so I was just slightly above his level. Based on the shadow, it looks like his tail is comp...

your level of quality in the images you share with us has quite tangibly improved! I am, for one, thoroughly enjoying it . Cheers, Filip
Point of focus... a simple case study
By: cshimokita : April 21st, 2019-20:30
Point of focus really defines the plane of focus... For the most part with a dSLR my standard procedure is to specify the central point as a single-point-of-focus and then use focus lock via a back button... when I recompose there is the potential of an O...
