Another one of those "help me decide" questions. Here's my gear for two Olympus E-M5 bodies: OM-D E-M5 (Black and Silver bodies), O12-55mm, P14mm, Oly40-150, Rokinon 7.5mm, Sigma 19mm/30mm, Oly45mm f1.8, asst Nikkor, Canon, Pentax and Olympus manual-adapted from 24mm to 500mm. I like a lot of different kinds of photography, so it's easier to say what I don't do a lot of, even though I might still do it some: I'm not a macro or street guy. Maybe someday. I'm a landscape and people-events (candids preferably, but do get the group poses often). Love ultra wide and super tele. Go to ballgames some, this year, China, Southwest, D.C., Rockies, and Ozarks, plus lots of walkabouts in Kansas hill country and lakes. I'd like to buy a lens now, before heading to China, and then maybe one in the late fall before the Eagles begin coming back to our area. Thought maybe the 75-300 could be handy for getting Eagles in flight, as my manual telephotos aren't much help for moving objects. Yes, I'd LOVE and intend to own something weather sealed like the 12-35 and 35-100, and those two would be just great for my travels with two bodies, but will not spend that money for a lens this year. Maybe in another 12-18 months. Also thinking of the 75 1.8, as with two bodies, I could head out with four lenses and mix and match as needed: 12-50 + 75 or 14 + 40-150. Low light, evening activities: maybe the 14mm or 19mm (wouldn't mind owning the Oly 17 1.8) on one body and the 45 are currently what I use, but sometimes missing more reach in faster glass. I'm leaning toward the 75 (still under $1000, but wish it were less), as the next lens, and the 75-300 later in the fall/early winter when the eagles are back and I need the reach and focusing speed. Actually, need more reach than that, but there's nothing I can afford and I have a Nikon 500mm and Canon FD 85-300 f/4.5 that can do a lot, and I can borrow a friend's Canon 500 f/4. So what to do? What am I missing or not considering? Hoping smarter heads with more experience will help me sort this out.
