I'm headed to the beach in the next few weeks with my family and am seriously looking at getting a 14-140 (newer f/3.5 version). I really like the idea, particularly when on vacation, of having a grab and go lens without having to worry about switching lenses. I currently use the panny 20mm on my G5 (almost exclusively) and really enjoy the pics I get of my 2 kids. That said, I often would love more zoom especially as the kids get older and get into sports, school concerts, etc. Would love 14-140 owner's thoughts on how this lens would perform on vacations and as a jack-of-all situations lens for when my 20mm is in the bag. I do love the shallow DoF i can get with 20mm and already know that's something I'll miss on the 14-140, but think the zoom capabilities might outweigh that. Cheers and thanks in advance!
