during my reading on the web it seems that for landscape shooting : "bigger the sensor better the result" FF (3/2) and APC-S (3/2 (1.5 crop)) or much better than mico 4/3. is it really what you guys tested ?
is full frame really better than micro 4/3 or APS-C for landscape or architecture shooting given the same type of wide angle lense ?
It terms of how much you can get into the frame, full-frame is beneficial but that's down to physics and geometry rather than what we test.
While focal lengths remain constant, they appear different depending on the size of the sensor as the field of view is reduced (the crop factor). At 18mm, for the sake of argument, on an APS-C sensor, the ~1.5-1.6x crop factor would result in a frame looking like you're using a full-frame sensor whose focal length is set at ~27-28mm. Though the aspect ratio is different, a Micro Four-Thirds sensor at 18mm would be the equivalent of ~36mm on a full-frame sensor.
