Is the panasonic lumix s pro 50mm f 1 4 worth it?
The Panasonic Lumix S Pro 50mm f/1.4 is worth it if you shoot full frame on L-Mount and want a fast standard prime for people, low light, or food. It has autofocus but no stabilisation, so it leans on fast shutter speeds or a well-stabilised body. It fits a wide run of Panasonic bodies, including the Lumix S5 II, a sensible everyday pairing, and the Lumix S1R II if you want more resolution.
If you're mainly after portraits and the f/1.4 isn't essential, the portraits guide makes a strong case for the cheaper 50mm f/1.8. And if you're unsure whether full frame is worth the extra weight, the sensor guide walks through that choice.
