I've spent the last week in New Orleans doing photography with the K5 IIs during Mardi Gras. Had a wonderful time. Shot over 1500 frames during a five day stay.
The K5 IIs performed perfectly. No problems, no glitches, no lockups.. just good dependable photography. The weather was a bit rainy and damp but the K5 was totally unaffected. Worst case situation was Tuesday night when there was fog rolling in off the Mississippi River and I was waiting to shoot the Trolley line that rolls beside the river. The fog caused a bit of condensation on the front element of the DA* 16-50mm but I was able to keep it clear by using a bit of lens tissue. The K5 IIs is a keeper. AF was accurate and performed extremely well in very dark situations at night.
The shot below is the kind of shot I drive 8.5 hours to take. Mardi Gras is so much more than the drunkenness and flashing on Bourbon Street. This was taken with the DA*16-50mm f/2.8 ISO 200 @ 1/80s.
