Compared with nex 7 or 6, Sony NEX 5r has no flash and evf. Is it inconvenient to take pictures at night?

when did night shooting have anything to do with EVF and flash? The principle of EVF and LCD framing is the same, and the night framing is enhanced by increasing the sensitivity, the difference is that EVF is finer. But in any case, it is brighter than optical framing. SLR can shoot night scenes, and micro-single framing is no problem.

as for travel, I think the size of the lens is more worthy of attention than the fuselage. From 3 to 7, the Nex is much smaller than the SLR anyway. However, except for 16-5, 16-set and 2-set, the other lenses are not much smaller than the corresponding lenses of SLR. So if you want to pursue portability, bring a 16-5, and choose the fuselage at will.
