Excerpt: I bought my refurbished G5 about a month ago having considered a compact camera (Fuji x20, Sony RX100ii) as a carry about camera. My main camera is the Nikon D7100. Having used this camera every day I'm finding it a wonderful little mirrorless camera. I've never used a fully articulated screen before and found the G5 screen to be wonderful to use. Very handy.
Summary: I got this camera as an upgrade for a single lens superzoom camera. According to the reviews it would be a significant upgrade in image qualty, and it was. The price was very competitive given the better images and the interchangeable lenses. On the down side, the manual was opaque, and the extended manual supposed to be online is unavailable. So figuring out the capabilities and how to use them has been an extended trial and error process.
