Best camera for the panasonic lumix g 14 140mm f 3 5 5 6 ii?
The 14-140mm is a Micro Four Thirds zoom, so it fits any camera on that mount. For most people, I'd start with the OM System OM-5 Mark II, which is a sensible everyday pairing for a zoom this size. If you want the best handling and speed, the OM System OM-1 Mark II is my pick at the top of the range. For video-first work, the Panasonic Lumix GH6 is worth a look.
On Micro Four Thirds, this lens frames like 28-280mm on full frame, so one lens covers most everyday subjects. If you want to compare that with other focal lengths, try the focal length converter.
