The K-50 is so cheap at B&H Photo right now that it's a no brainer.
From cheap to high:
Body = $397
Body + 18-55 kit: $426
Body + Pentax 50mm 1.8 = $517
Body + 18-55 kit + 50-200 kit = $527
Body + Pentax 35mm 2.4 = $544
Body + 18-55 kit + Pentax 50mm 1.8 = $547
Body + 18-55 kit + Pentax 35mm 2.4 = $574
Body + 18-55 kit + 50-200 kit + Pentax 50mm 1.8 = $647
Body + 18-55 kit + 50-200 kit + Pentax 35mm 2.4 = $674
Body + 18-55 kit + 50-200 kit + Pentax 50mm 1.8 + Pentax 35mm 2.4 = $794
I'd like to see if anyone can find a DSLR or Mirrorless camera with 2 zooms & 2 primes for less than $800 from any other manufacturer. Heck, I'd like to see a weather sealed camera with 2 control dials at that price too.
