Hi! I'm new the forums, new-ish to the micro 4/3rds (I have a Pan D6), and new again to photography. Meaning...I took B&W photography throughout high school with my grandfather's old manual camera. I wasn't bad. In fact, I thought I was pretty good. I'd probably cringe at the photos now, but my interest has been once again sparked...too many years later. I have only the kit lens and an Olympus 45mm 1.8. I love the 45mm, but I'm thinking a good telephoto lens would give me more variety in my photos. The kit lens isn't terrible, but the more I (re)learn about photography and the more I learn about this camera, the more I realize it's not that great either. If you could buy only one lens...and not for more than $500 (is that even possible?)...what would you buy? Would you go 3rd party rather than brand name? I know there are threads similar to this out there, but the few I saw were from years ago, so I thought technology has improved, and there are probably more options out there now than then. I'm sure I'll be asking many, many questions in the months to come, so I thank all of you experts ahead of time.
