Currently sitting around a pool on Ischia, my thoughts turn to toying with the idea of something tiny and high quality. m4/3 is not for me, so in today's market that means Sony. I'm happy with a 2x zoom, and value lens speed over reach. I want decent jpgs with the ability to capture raw for those times when I want more flexibility to get to the desired final result. I know the user interface is more PlayStation than analogue, but I am prepared to compromise - a bit, but see below. Considering, therefore, the RX100 range from MK lll to MK lV, these are my questions: - Is it easy to adjust aperture and exposure compensation on the fly - they are the parameters I change most often - Is it instantly ready to use once turned on? - Is the zoom stepped or continuous and does it remember the last setting? - Does the WiFi work effectively for transferring images to (android) phone or tablet? - Can you shoot raw and best quality jpg simultaneously? - Is there a built in raw conversion capability? - What is the mono output like? - Is it robust, and free from dust issues? - What are Sony like for servicing (I have had some experience of them with portable telephones...) - Can you turn the screen off completely and just rely on the viewfinder? - Does the viewfinder have a level or grid? - Is the viewfinder good quality and free from flare? - Given all the above, and my likely usage - shove in a pocket or pouch and take everywhere, particularly travel, for street, architecture, interiors, occasional portraits, occasional macro, never flash (other cameras are X-Pro2, X100F and GR) - which model would you recommend, and - would you advocate buying new or used? Thank you kindly for your time and attention to this matter.
