Manual focus: No question.
Critical focusing: It depends. A well-calibrated PDAF system can be more precise than CDAF.
Granted, it is generally not possible to achieve optimal PDAF calibration (micro AF adjustments) over the full operating range of a lens, in particular with zooms.
However, despite the hype created by the MILC fanboys from DigitalVideoReview, MILCs haven't replaced DSRLs just yet.
As soon as the professional sports shooters switch to Sony A9's or similar, I'll believe the hype. Until then, I take everything from DVReview and other publishing outlets with conflicts of interest with a big grain of salt.
Originally posted by richandfleur The Pentax K-70 has in sensor phase detect sensors (which are used to give continuous AF in video for example) and I’ve not heard an outcry at the poor image quality from this.
Part of the reason why you haven't heard an outcry is because DigitalVideoReview prefers to manufacture an outcry over the minimal RAW smoothing of the K-1 II and do not subject their MILC darlings to the same level of criticism. Having said that, even DVReview has published articles about the striping (in backlighting conditions) and banding (when pushing shadows) some OSPDAF (on-sensor PDAF) implementations (e.g., those from Sony) produce.
Yes, in many shooting situations OSPDAF technology will produce images that are perfectly fine and will perform much, much better in video, but for a still shooter who has not been stifled by regular PDAF, the recent developments in the MILC arena are a step backwards, AFAIC. I could image eye-AF to be very handy, but I wouldn't pay the price for that by having to look at a mini-TV set with an off-putting white balance, choppy display when the camera is focusing or taking burst shots. Have you seen how poorly the brand new Canon RP handles burst shots at a measly 3-5fps? Good luck with following a moving subject because the viewfinder will show you what has happened a short while ago, not what is actually happening. There are of course better implementations but they cost a pretty dollar.
