I've looked through numerous threads (including the lens archive), searched the forum for a similar thread and couldn't find one. I'm torn which native lens to get: Oly 17mm, Panny 20mm or 14mm. I'm liking what I'm seeing from all the photos in the examples threads. I've purchased some manual lenses to go with the camera but sometimes I'll need/want autofocus for street photography (just starting out with manual). Do I just go with the cheapest at this point? Is the Oly slower to focus on the Panny body (think I read that somewhere)? Which is the fastest focusing? Which is the quietest? Please help me make up my mind!
