As an amateur camera user, I was looking for a mid range camera with video recording and a decent zoom option. The RX100M5 was out of my price range and did not have all of the features I was after. Two cameras stood out, the Panasonic Lumix LX15 (LX10 in some markets) and the Panasonic Lumix TZ100 (ZS100 in some markets).
Both cameras have a similar specification (discussed later on) and are housed in a similar body. The end result in everyday shooting may look similar but there are a few features that make all of the difference in choosing either camera.
You have to ask yourself, what do I want out of the camera? What will I be shooting? How near or how far will my subject be?
