Being a long time LX5 and m4/3 user, I took the plunge and upgraded to Sony RX100 V. Biggest mistake ever.... Not sure why the reviews are so positive. Handling is bad... lens ring control is laggy with 1 second response time. Lack of physical buttons mean i have to dive into the menu 2-3 level to reach most options. I was spoilt too badly by my LX5 where i can change aspect ratio, iso, aperture, shutter speed, wb on the fly.
I also had very bad experience with the focusing which would defocus and refocus 50% of the time, causing me to miss the moment. Also need to zoom in and check all my shots as some of the "in focus" photos turned out to be slightly blur.
Photos also had very harsh constrast and i had to postpocess almost all the shots. Probably require a lot of tweaking of the settings which i must agree is quite comprehensive.
Saving grace is the useful HDR mode which helps quite a fair bit. Portrait range bokeh is also quite acceptable for a compact camera but don't expect it to match up to APS-C sensors.
Ended up selling my RX after using it extensively for 4 months. LX100 seem to fit the bill for what I need - lots of manual controls and ease of handling. But hesitant as LX200 might be right around the corner
