It was dark out there only lit by a small porch light. I was in my office and looked out the window to see the two Raccoon cubs coming for water.
I had the Tamron 70-200 2.8 mounted and fired through the window. Focus lock was instant in the low light....love the K1, and love the fast and sure AF. Some complain, but it is very seldom that I try to shoot speeding bullets, so for me it is wonderful!
1/60 handheld (great SR!) f2.8 70mm @ ISO 12800...works for me! ...oh yeah...it was shot in Crop Mode.....gotta love it!
BTW- If you are shooting a Canon or Nikon with the Tammy 70-200 don't try this at home. The Tammy has no IS so you will need some good SR at 1/60 handheld...and you don't have it...do you?
Regards!
