I haven't had a chance to experiment much with my G5 after purchasing it a few weeks ago. I have an upcoming vacation and I really want to take the G5. I currently own two native lenses (the kit lens 12-42 and a 45 to 150). I purchased the lens mount adapter to mount Nikon lenses on mt m4/3 body. So far I experimented with only one manual focus lens; the 50mm 1.8 Ais lens (late model without prong; not the "E" version). The one or two pics I took eith it turned out quite sharp. I don't have the time or resources to order a better native lens at this time, so I am considering taking my old Nikon primes with me. I currently have a 24mm 2.8, 35mm 2.0, 50mm 1.8, 50mm 1.4, 105mm 2.5. In auto focus I have several others but I feel they are too large and heavy to pack on this upcoming trip. Do the adaptive lenses offer better IQ or any other advantage (other than speed and in my case that I own several older lenses Any suggestions regarding which lenses I should pack in my small bag for this vacation; my old Nikkor primes or my two native lenses? I'm not sure if it helps any, but I'm almost certain I won't be shooting any video.
