I've narrowed my choice to one of these 3 cameras. Each one generation old, so less expensive when bought new or used. Ouestion 1--how significant is the dslr mirror slap from the Nikon (or any) D5300? Back in the day, rangefinders were judged to gain a stop handheld advantage against full frame slr film cameras. Has this changed? Question 2--does the 4 stop inbody antishake advantage of the Olympus E-M5 overcome the superior size/low-noise capability of the Fuji 16mp Xtrans sensor or the Nikon/Sony 24mp sensor? This is primarily in the street or travel genres with no flash and interiors as well. Particularly with prime lenses--I know Nikon and Fuji put antishake in their zooms. Thanks.
