I opt for Sony A7II (RM4800) + SEL28F20 (28mm) (RM1600) + SEL55F18Z (55mm) (RM2900) as starter kit to cover Portrait (Pet also) + standard landscape.

Total RM9300.

If you have budget and want wider landscape, you can get SEL1635Z (16-35mm) (RM4300).
OR
If you don't mind manual focus and huge lens, Samyang 14mm f2.8 (RM1300) is value for money.
OR
If you want small, lightweight ultra wide angle lens but dont mind manual focus, try Voigtland 15mm F4.5 vIII (RM2800).
