i found a camera with a low shutter count of 46 on ebay in england, where i'm from. i passed up a g617 from taiwan with a 5 shutter count, and air bubbles between the lens barrel and front element. i know i must refrain from posting the link to the auction here, however can someone please summarise the common issues with a second hand g617 please? i did not go for the gx617 because the bubble level is not visible through the finder, thus limiting handheld use greatly.
