I am looking to upgrade my G5 to an EM-1 very soon. At my son's first little league basketball practice I found my Panny 14-140 f4-5.8 woefully slow (my Canon FD 135 f3.5 was better). Even with pushing the ISO to 1600 the shutter speeds were too slow for a good sports shot. I am not trying to get pro shots, but would like to get a few good ones. With the EM-1 I will have more lens options. What do you guys think for a tele zoom for kids sports? My current thought is either Panny 45-175PZ (only a little faster, but compact and PZ) or the older 4/3 Oly 50-200 2.8-3.5 (much faster, but big and how's AF). Anyone have EM-1 experience with these? I don't necessarily mind the size of the 50-200 if the AF and faster aperture would allow me to get some decent shots of him. Other ideas? Thanks a lot for your help.
