BAck to the OP original post, he/she's asking for suggestion in expanding his/her gear buying lenses with good cost/performance ratio. There are no simple answers. My experience is that having 3 lenses (10-20; 35 ; 70-200) covers most of the situations . With Pentax I love my old primes (20;28;55;200;300 ) . I had DA17-70 and 50-200 for the K5 but I let the k5 go and save money for the K1. My perspective is having 2 different setups: AF with APSC and almost zooms; FF (in the near future) with primes. I do love primes much more than zooms, but I admit zooms are much more "easy" or versatile. But, as in the old good days , a small bag with a FF and 20/24,50,135 primes is something I miss.
