I bought this camera 4 months ago. I was very satisfied and took stunning pictures with it. To my bad luck I mistakenly dropped the camera once. The edge of the viewfinder got misshaped which caused that I cant open the viewfinder and the camera constantly monitors that its open (viewfinder starts working). Its still under the one year warranty. I hope to contact Sony soon and see what's my further steps.
My DSC-RX100M3 has been a workhorse for the past three years--I bought it for wide angle and low-light uses, and it has been great in those respects--but in the past year the C/Delete button has started triggering the recording function (incredibly annoying) and the software stopped working (terrible software, but the only way to transfer files from the camera via wifi). There have been no firmware updates while I've had the camera, it's out of warranty, etc. Sony should do more to stand by their products.
