Like many other photographers, some landscapers want a small camera to always have with them; you can't lug your DSLR gear everywhere, if only because it can be socially unacceptable. I don't think most people are buying these compacts as a primary camera, especially not for landscape and architecture. Even though these are small sensors, the quality difference between e.g. a Sony RX100-3 and my Canon 450D DSLR with 15-85IS lens is pretty small as long as there is decent light.But let's be honest here, true "landscape photographers" would not be shooting with either of these cameras. The detail that they need in their shots - especially if printing at a decently large size - cannot really be accomplished with any small sensor camera. Even the 4/3 sensors - which I happen to be a big fan of - and are what 4 times as large as these, really don't do that type of detail well enough.
Why are people photographers shooting with G7X, wouldn't a DSLR (with its better DOF control, better feedback, faster operation etc.) be better there as well?
P.S: m43 sensor is 4 times as large as a 1 inch sensor?? You should read up on the subject because you are totally wrong. LX100 can hardly keep up with the 1 inch Sony sensors ...
in landscape photography there usually is not a 'prime subject' that one puts in the middle.I don't understand why people feel that they need ultimate sharpness "edge to edge" from these smaller cameras. Aren't they generally putting their prime subject more towards the middle?
Landscape photographers want good detail into the corners because of the way viewers look at a landscape image, and because most landscapes have relevant details right into the corners (unlike the average people / street photography shot). This has nothing to do with 'measurebating', people/event shooters simply have very different requirements.Yes, that "edge to edge" sharpness might technically be a good indication of how good the lens is, but IMHO these cameras are not really suited for that purpose (landscape photography).
