Haven't seen a thread here on this lens yet.
I was hoping to have it together with the K1 for a trip to Hawaii last week. But, heartbreak, my flight left literally 3 hours before the camera was delivered to my doorstep. I tried various ways to get it redirected but just couldn't get that to happen.
Anyway, on to the shots, how about some lava? shot with K3ii. handheld. hanging from a moving helicopter. a big beast of a lens but superb, pro quality IQ. Can be shot handheld with K3ii. I'm sure it will fare even better with the K1.
This was at 1600ISO, 330mm, F5.6, 1/1000
