About Pentax Updating and adding new stuffs I cannot agree more on the first topic.
--
Pentax is very sadly - manufacturer
which does not do any kind of later incorporation of the new things.- with firmware updates - in their cameras
For me,
I found few things which actually can be add - very simply - without to much effort - like different active scrren propotions for shooting in different ratios - in LV only.
--
Realy don't understand
why that option is still missing one in LV - and I really have not symphathy for such lack of will in Pentax department to do such a simple task.
--
For the tracking :
--
I really don't care about sport - and particuraly TRACKING . If I would be such kind of photographer - I think the Pentax system would not be my first choice,
but if I would must take such pics
for, let's say , one part time job for a client - I think - my KP and K3 - with my prefocus technique could be enough.
--
In most scenarios I found the tracking is unreliable - and maybe complicated as well, and if I want a good clean shoot, I would not relly on such AF technique, but rather on the faster recomposition, and faster single AF, or even prefocusing the area.
So If I would have to do some unpredictable action, with fast moving subject flying or moving all around,
things - like tracking eye, or tracking subjects
would be
avoid by me anyway.
------------------------------
I tried Pentax tracking, and yes it can be good, but your subject must be always in the middle of your frame, and you have to practice this - to get the best results.

for the updating thing - I simply realise two years ago, or even more - that Pentax don't do such stuffs - and I've completely ended my hopes in that area - and take my Pentax camera - as it is.
