If it was our money
The Sony A6400 is strongest when autofocus reliability, compact size and lens availability matter more than in-body stabilisation or the newest video features. It can be especially attractive used, provided the physical condition, shutter use, battery condition and seller protection are checked carefully. When buying new, compare its price with newer Sony APS-C bodies because the A6400 only represents strong value when the saving is meaningful.
