Step-up filters can be problematic on this lens as it retracts fully on power down

This is a welcome new addition to the pancake lens crowd. Very well received by the public, it is perhaps everything that the Olympus 17mm f/2.8 could have been.
Panasonic’s first Micro Four Thirds pancake prime lens is a stellar performer with center to edge sharpness, and one of the fastest lenses available in the double gauss design format.
Construction & Ergonomics
Built like a tank, the Panasonic features a full metal mount, and is substantially heavier than it looks. Perhaps the only fault against it would be the manual focus ring which does not have a fixed start or stop end to end. However this is really not an issue with the design of the lens itself- Micro Four Thirds lenses typically have as a design feature their drive motors decoupled from the actual focus ring.
