So, recently I replaced my RX100m2 with an RX100m4. Although I was primarily interested in the viewfinder, there were two other issues I hoped had been addressed, the very long shutdown delay (I use my camera outdoors - waiting 15 seconds for the lens to retract so you can stow it becomes irritating after a while) and the lousy timekeeping accuracy - I kept having to set the clock. Why is this important? Well, I like to know the exact location where my pictures were taken. For this I use my GPSMap 62st from Garmin and a program named GeoSetter. The only prerequisite is that the time stamp in the image be accurate because that's what the program uses to synchronise the location and the image. A one minute timing error would translate into a significant location error (the magnitude depending on the mode of travel obviously) - in fact anything over a five seconds would exceed the inaccuracy of the GPS position itself and thus dilute the accuracy when hiking. The good news is that the shutdown takes a lot less time with my Mk IV than it did with the Mk II. The timekeeping, regrettably, seems just as bad. I recently measured the error by photographing the screen of my GPS showing the time, then comparing with the embedded time stamp. Over 4 days the camera had gained 8 seconds. Simple extrapolation shows this to be a minute per month - which is ridiculous, cheap watches do better than that. Do I have a bad copy or have others experienced this as well?
