I've got a KM5D.When trying to capture sportsaction, I hold the shutter release button 1/2 way to engage the autofocus, then hold thatfor long time waiting for the right moment. By a long time, I mean for 30-90 seconds, repeatedly, as long as fingers can take it.
1. Will this shorten the life of the mechanism?
2. Does it drain a lot from the battery?
Thanks in advance.
