Which would you prefer? RX100 M3 or Alpha 6000? The latter is cheaper sia! @_@
seriously at 1199, may as well get the a6000.
RX100M3 and A6000 are different, not apple to apple comparison.
RX100M3 is a high end PnS. It allows the convenience of a small package and a large sensor (1" size) and a relatively fast lens. U cannot change the lens as it is a PnS. U can fit the RX100M3 quite comfortable in a cargo pants pocket
A6000 is a interchangable lens camera with an APS-C sized sensor. It is larger than the RX100M3, hence u still need to bring a bag out if u use the A6000. It allows u to change the lens based on the effect u want.
I have both the RX100 (1st generation) and A6000 and use them for different purpose.
If u get the A6000, u must be prepared to spend more on high quality lens As with all kit lenses, it has its limitations. E.g an E-mount CZ 16-70mm F4 will cost about $1300. A prime will cost less, a 50mm F1.8 is about $500
I started on the Sony mirrorless system from the Nex-3 days. Frankly, I would very much want to ditch the kit 18-55mm after using it a few times. The IQ is so-so only. It is too slow for my usage. The kit 16mm F2.8 is worse. The distortion at the ends is terrible.
I upgraded to A6000 without getting the kit 16-50mm as I already have a good collection of lenses for my useage. The kit 16-50mm has a worse IQ than the old 18-55mm.
Which camera to buy have to depend on what you want to use it for, and whether you are prepared to spend more in the future to upgrade
