HI all. Recently purchased my first m4/3 camera a Panasonic GX1, and still getting to know it. It came with the new pancake PZ 14-42 X lens, which to be perfectly honest, is pretty poor (well at least on my camera). I've seen a number of threads on different forums concerning this lens, and it looks like I have one of the "iffy" lens / camera combinations. I did also get the camera with the lovely Pancake 20 F1.7, and that shows me the quality the camera is capable of. To that end, and as I'll only really be using the GX1 as a travel and go-anywhere camera, I was thinking of picking up a Panasonic 14-140 lens as a decent range all in one package that can stay on the camera 90% of the time. So 2 questions please. Is the 14-140 a better quality lens than the 14-42 I have (i.e. sharper), and secondly, having never seen one in the flesh, would the 14-140 be physically too big for the little GX1 or just about right ?
