Get Sigma 100-300/4 and be happy With K3 you have same reach as 150-450 on FF
Btw what is wrong with Sigma 50-500? It is not that bad, but eats light quickly, needs F8+ and fast shutter speeds...

K3 + 50-500/4-6.3

Well, yes, a 300mm on a K3 has the reach of a 450mm on FF, but 450mm on a K3 has the reach of a 675mm!
Just looking for more reach, without dropping $1500....
