Hi all,
Recently bought the K-m (body only) and the 18-55 (AL, not AL II). Having fun
. Doesn't have the reach on the long end, obviously, but I made due on a recent trip to NYC.
I was seriously looking at a walkaround lens (probably Pentax 18-250, though I had poked around for an FA 28-105 3.2-4.5, which seems like a nice compact lens and a good match for the K-m, though lacking in the tele end), but recently went to my daughter's dance recital and realize there is no substitute for a fast indoor lens for those kinds of venues.
My question: how fast is fast enough in these settings? The 50-135, while a chunk of change, covers a lot of the focal ranges that folks would shoot in primes in that sort of context, but it is 2.8 at widest aperture. Wide enough to stop motion in low light?
If not, what would seem to be the best prime lens option? The FA 50s have wider apertures, but I'm not sure they have enough reach. 77? 85?
thanks for any suggestions!
