Just guessing here, but a 300mm is too short for most of what I shoot so the 50-500 Bigma gives me the range I need, although the IQ is not as good as a good 300mm 2.8. However, with the cropping abilities of the K3 it might be better to use a very good 300mm and crop?
I'd love to have a Sigma 500 4.5m but I'd have to go a year without buying squirrel feed...and you know I can't do that!
Hungry squirrels love to eat Jeep wiring.
This is a 20% crop of the full frame, shot out my window at about 50feet distance, ISO 3200....It's about as good as my Bigma & K5 will do under those conditions. I'm thinking the K3 might do better...anyone want to guess?

I can't match you guys, but it sure doesn't keep me from enjoying your fantastic shots!
