Just noticed that with my new 50-200/4-5.6 ed wr lens mounted the k--5 doesn’t
ask me to set the focal length of the lens when I start it up. Which reminds me
that it does when I’m shooting in manual mode. What do I do in that case when
the lens is a zoom lens?
When shooting with a manual lens that doesn't communicate its focal
length to the body, there is no way to tell the body that it's a zoom
lens. The body uses that setting for shake reduction. There wouldn't
be much point in telling the body "It's a 70-210 zoom," because the
body still wouldn't have any way to tell which focal length the lens
was set to at the moment of exposure--the lens doesn't communicate
that information, which is the whole problem in the first place.
So the best you can do is tell it what focal length you'll be shooting
the lens at. (Or, pick some reasonably close average value, or disable
SR so the setting doesn't really matter.)
Well, I'll be damned. I never knew that had anything to do with the SR.
I always just entered the near-end of the focal range so I'd have some
clue which lens I used if I ever needed to refer to the EXIF later on.
