Lens Review
Introduction | Best Prime for Micro Four Third mount on the Olympus OM-D E-M5 | Panasonic Lumix G 20mm F1.7 II ASPH lens performance | Panasonic Lumix G 20mm F1.7 II ASPH versus competition | Conclusion

The original Panasonic Lumix G 20mm f1.7 ASPH was one of the most prized lenses for both Panasonic and Olympus users and the announcement of a revamped model with the same optical construction was a surprise.

In reality, the Panasonic Lumix G 20mm f1.7 II ASPH performs very slightly differently to the original. It’s still an excellent lens, but it’s not quite the performer of it illustrious forebear.
