I am unsure how an advanced user you are, but the following basic settings may help:
- Dial mode to Hypermode P - It is a kind of semi-automatic mode in which you can set manually the aperture and shutter using the back and front dials if you need.
- Focus: center point
- Metering: center weighted
- RAW, RAW+ or JPEG: up to you - Everyone if different ...
- Switch off all in-camera post-processign incl. lens distortion correctin, high ISO NR, ... - Any in-camera PP does slow down the camera write-up to the card and is counter-productiion with high-continuous bursts, and in-computer PP is always more effective
- auto-focus: AF-S
- Copyright: set your copyright settings - in my case, I put my full name
In addiiton, I always set my shooting mode to Hi continuous mode. I shoot often sport and actions, and I like to shoot in bursts to get all the action.
In terms of prime lenses, Pentax does offer a very broad range of prime lenses incl. older lenses. The choice is yours really. The 35mm f2.4 is considered very good value for money. The 40mm pancake is very small and help to have a small camera+lens package: eg for street photography or when you need to be non-intrusive. There are other great prime lenses incl. the FA Ltd series (sometimes regarded as the best lenses ever made ..), the DA Ltd series, the older FA* series, A series. ... The list is long
Personally I have other primes, incl. the FA31mm f1.8 and Voigtlander Nokton 58mm f1.4. In any case Pentax does offer a wide range of
great prime lenses. Welcome on board.
Hope that the info will help...
