While Sony IBIS (SteadyShot) can damage image sharpness, handheld shooting at dusk can be a huge win, as with all these handheld examples.
The about $1498 Sony Planar T* FE 50mm f/1.4 ZA looks to be a winner, with high sharpness and micro contrast wide open coupled to gorgeous bokeh. Its only downside is size and weight as compared to the Zeiss Loxia 50mm f/2 Planar and/or the Zeiss 55mm f/1.8 Sonnar.
