I am from a RX100M3 about me and I used it when traveling. It is for me the ideal case: it fits in your pocket (a large pocket anyway), it is fast to both light that trigger and the quality is excellent. The fuzzy background are pretty large aperture and very helpful lumosité viewfinder when the outside is strong, although there really fault paste the eye or he goes off sometimes. The wireless feature was very useful to transfer photos to my iPad on a trip and view photos on a bigger screen or an iPhone to send them by mail. I purchased the leather case, very convenient to protect the device and wear slung discreetly, very well adjusted to the dimensions of the case. Must be removed to change the battery but it is quick. I also wanted to buy the small handle that sticks for better grip, but it is not compatible with the case. I can not judge the flash that I almost did not use, I prefer to use the brightness of the lens mount or sensitivity. On this last point, the camera is okay but not great, the high sensitivity images are slightly soft to reduce noise. I have not used the video, for me it's a camera to take pictures ... As for areas of improvement: - The device turns off when folded the viewfinder, I think it should not be the case if he was turned out in the viewfinder. - But above all, for me who works hard in aperture priority and have set the aperture setting on the lens baque, it is far too slow: we must do at least three laps to move from fully open most closed, it takes a long time! I missed the pictures because I could not choose quickly diaph. It should for instance switch between the main openings (1.8-2-2.8-4-5.6 ...) by turning quickly, then choose 1/3 diaph turning more slowly. I expected to go from 1.8 to 11 in a U-turn at maximum, beyond we must let go of the ring to resume, it wastes time and it's moving. - Finally, an all-weather design was apréciée: considering the price, I have a little crain for the device in dust or moisture ...
