Compare the Panasonic LEICA DG SUMMILUX 25mm f/1.4 and the Lumix S PRO 50mm f/1.4 to find the prime lens that fits your camera system and shooting style.
Quick answer
Choose the Panasonic LEICA DG SUMMILUX 25mm f/1.4 if you shoot Micro Four Thirds and want a normal field of view in a compact, affordable package. Choose the Panasonic Lumix S PRO 50mm f/1.4 if you shoot full-frame and need maximum sharpness and light-gathering for professional work.
System matters first
These two lenses are designed for different camera mounts. The LEICA DG SUMMILUX 25mm f/1.4 fits Micro Four Thirds bodies, where it delivers a 50mm equivalent field of view. The Lumix S PRO 50mm f/1.4 is built for Panasonic's full-frame S-series system, giving you a classic standard perspective. Your choice starts with your camera system.
Speed and depth of field
Both lenses offer an f/1.4 maximum aperture, which helps in low light and provides shallow depth of field. On full-frame, the 50mm f/1.4 produces a noticeably thinner depth of field for more pronounced background blur. On Micro Four Thirds, the 25mm f/1.4 still creates pleasing separation but with deeper focus at the same subject distance due to the smaller sensor.
Image quality pedigree
The LEICA DG SUMMILUX lens carries Leica optical design and uses special technologies to control aberrations, delivering excellent sharpness for its class. The Lumix S PRO lens is part of Panasonic's premium S-series lineup, promising maximum sharpness and a premium optical design suited for demanding professional use. Both offer high image quality, but the S PRO targets a higher resolution full-frame standard.
Trade-offs at a glance
