NSFR photo. A kestrel pair in the rain.

K1 500 f4.5 Sigma. This was handheld on a beanbag using electronic shutter. I find I use it often.

@biz-engineer Very nice B&W shots ! I love the depth of field. The AF of the Pentax K1 + 70-200 seem pretty accurate, how much keeper percentage ?

About 100% keepers, due to the cars going fast, I shots 3 to 4 photo at each car and kept the one where the car was framed correctly, for 9/10 of the cars, it was in focus for the frame I wanted to keep. I used the settings recommended by beholder3 in his article on PF.
