Sony FE 135mm f/1.8 GM

The floating focus system lets me lock onto eyes instantly, even wide open at f/1.8; the bokeh from those Super ED elements is just gorgeous. Shot a portrait session last weekend and every frame was pin-sharp.

The XA element really does make a difference in sharpness—the details in my portraits are incredible even wide open. Bokeh is buttery smooth without any onion-ring effect, which was my main concern.

The floating focus system keeps everything sharp even when I'm tracking a bird in flight, which surprised me for a 135mm. The Super ED glass really cuts down on color fringing in high-contrast shots.
