The 50-200 is a much nicer lens than the 40-150. Especially the new SWD version. I have the old 50-200 and will also be adding in the swd version in the near future. It is a stop faster, the bokeh is better. In low light, that extra stop will help

Sharon, your dogs are beautiful. I do not shoot raw with my Oly cameras because I have found the jpgs to have better color than any of the raw converters out there besides Studio or Master and both of them are way too slow to be useful. I got tired of shooting raw and not liking the results as much as the jpgs sooc. So, I simplified my life and just shot highest quality jpg.
