Launched alongside the new Leica SL3-P camera, the Leica Summilux-SL 50mm f/1.4 ASPH claims to be the world's most compact 50mm f/1.4 autofocus lens. At just 75.5mm long and with a diameter of 74mm, it is a substantial shrinking of the original Leica 50mm f/1.4 SL lens launched back in 2016.
In 2023, Leica introduced a smaller version of its Summicron-SL 50mm f/2 ASPH. Now the shrinking process has been applied to the 50mm f/1.4 – and remarkably, it is even smaller than the latest 50mm f/2.
