Good place to share your discovered configurations in Pentax menus. Remember that Pentax options are truly vast and camera is extremely customizable.
Let me start.
I use my K3 II now mainly for sports...but prior to K1 purchase was using it as all around camera.
So what works for me.
BACK BUTTON FOCUS:
How to enable:
Page 4 under Camera:
Button Customization - AF button set to AF2 (AF with shutter release button is disabled so AF is performed with AF button)
Under Custom Functions Page 1.4 - AE-L with AF Locked set to option 2 (ON) - AE is locked when the focus is locked
Now specific SPORT configuration options (although All Around for me) that has worked well for me:
Always use AFC (AF button + wheel to change from default AFA - we want to be in continuous mode)
Continuous Shooting - set to H (High) - we want to capture up to those 10 fps... speed (Up arrow to select from Main screen)
AF mode - I use 9 user selectable points (red square instead of white) (AF button plus wheel to select). This way it is easy to control and keep moving object in frame (eg conrtol using Up/down/left/right arrows if needed).
Custom Functions Page 3.16 1st Frame Action in AF.C I have found that option (3) works best for my style of shooting - eg Focus-Priority (Start shooting after adjusting Focus). Basically first shot only after focus obtained, make sense
Custom Functions Page 3.17 Action in AF.C continuous Default is Focus Priority, which is rely on Camera "brains". I want to be more in control here i set it to 3 - FPS-Priority Maintaining capture frame rate takes priority. Cause I use back button focus and much smaller focusing frame (9 points) it is a lot simpler to keep object in focus.
Next one I personally don't touch 3.18 Hold AF status - keep it off. Basically if object is outside 9 points, I want camera to throw focus away and dont try to re-focus for me...You could change it to other options if you'd like, but by my observations it will be slower.
Now here are Miscellaneous K3 II options I have found useful:
Let's start from Custom Function Page again page 4.23 Save Menu Location - I set it to (2) - Save menu location. Basically once you are getting out from menu camera remembers where you have been, Extremely useful for my type of usage.
Memory Card Option (Camera 1st page) - both 1 and 2 cards are used for RAW
Image Capture Settings (Camera 1st page) - set to RAW and RAW File Format set to PEF (not DNG !) Reason. I use Capture One as PP software, and PEF file support is vastly superior to DNG files according to profiles.
Horizon Correction (Camera 2nd page) - is set to TRUE. It is the MUST setting for Landscape photography, where camera will correct Horizon on the fly, rather than losing pixels in post processing.
Memory (Camera Page 4) - I uncheck EV compenstation and Flash Exposure Compensation, Digital Filter, HDR Capture and Pixel Shift from it, I don't want to keep those values once I restart the camera.
This is pretty much it.
Very very similar settings on my K1 as well (different UI though but same settings), could post if there is interest.
