The type of photography that you are planning to use is an important decision factor. Here we have evaluated the Panasonic 12.5mm / F12 and the Leica Summilux-M 50mm f1.4 ASPH for their suitability to various photography scenarios:
Size and Weight Comparison
The size of a lens is a crucial factor to consider when comparing two lenses. Leica Summilux-M 50mm f1.4 ASPH is the longer of the two lenses at 53mm. The Panasonic 12.5mm / F12 with a length of 21mm, is 32mm shorter. On the other hand, the Panasonic 12.5mm / F12 has a larger diameter of 75mm compared to the Leica Summilux-M 50mm f1.4 ASPH's 54mm diameter.
The weight of a lens is equally significant as its external dimensions, particularly if you intend to handhold your camera and lens combination for extended periods. Panasonic 12.5mm / F12 weighs 45g, which means it is 290g (86%) lighter than the Leica Summilux-M 50mm f1.4 ASPH which has a weight of 335g.

Panasonic 12.5mm / F12 is a prime lens with fixed focal lenght of 13mm which has an effective (full-frame 35mm equivalent) focal range of
26mm when used on a FourThirds format camera.
On the other hand, the Leica Summilux-M 50mm f1.4 ASPH is a prime lens with fixed focal lenght of 50mm.
