>>3115793In addition what others have said, mk3 has f/2.8 on the long end, while mk1 has f/4.9, and there's an evf on the mk3 as well, tho it's barely usable... I have the RX100III aand it's ok for casual snapping, but the IQ really isn't THAT good. The image is kinda noisy even at small iso, but luckily not very visible in small prints, sooc colors are kind of shit. The lens is sharp at least. Here's a picture of a flying rat, taken with said camera.
