Before my bird-chirping sound now audible on the DA* 50-135, I never
experienced what you describe below. But I have to send my lens in for a
check-up and it's a bit more sluggish now as well as chirpy. Cheers,
Christine

Subject: SDM in Cold Weather
Something I've been meaning to ask about. Has anyone had the experience of
shooting with an SDM lens, fresh out of the bag from a warm car and into
early morning air chilly enough to produce visible breath fog.
This happened one morning while at the coast DA* 50~135). AF felt as
though it were operating in at least cool molasses. I was attempting to
track some birds in flight and had to pick them up early and try holding
focus awaiting the shutter.
Later in the day, I took it out into the warming sun for a few minutes and
tried it again. This time it seemed to be normally quick in response.
I was relieved, but made me wonder if it's starting to wimp out. K20D
battery appeared to be fully charged.
Any such experiences?
Thanks!
Jack
