Originally posted by blackest Yes I know, it's just little things like why no other focus point other than centre on manual focus lenses. the focus points are part of the camera not part of the lens.
That is reasonable. It is not a feature I have missed despite having mostly manual focus lenses, but that is a reasonable request.
Originally posted by blackest I guess it might be that Sony controls some of the firmware for the camera and sensor so Pentax / Ricoh are limited on what they can do.
Pentax may be a Sony customer for image sensors, but it is unlikely that they control camera features.
Originally posted by blackest I'd love better manual lens support but that doesn't sell lenses, although it might sell bodies...
That is a good point. I know many people who purchased the original A-7 Sony primarily because of the breadth of manual focus lens support. OTOH, Sony does not feature manual focus confirmation on that model.
As I mentioned above, I have never wished for the ability to choose focus confirmation point for manual focus*, though it just occurred to me that the benefits might be less than appears. Much depends on one's eyesight. Even the stock focus screen will outperform PDAF at other than the center column of AF points found on higher model Pentax cameras.

* One of the reasons may be that from 1970 to 2007, I used manual focus SLRs having focus aids positioned at center. About 2008, I equipped my K10D with a Katz Eye focus screen having similar focus aids and my K-3 continues that practice. The best focus with my Pentax is done using either PDAF at center, manual focus using my peepers, or magnified live view.
