Panasonic LUMIX G 20mm f1.7 and 20mm f1.7 II ASPH lens reviews: Has Panasonic improved its classic standard prime?By Kevin Carter - Thursday November 07 2013 Lens Review
Although the original was highly regarded, the range of rival offerings has increased dramatically. Olympus introduced a high-grade 17mm f1.8 model to compete directly, and Panasonic added a Leica branded 25mm f1.4 that must surely be tempting sales away from the diminutive 20mm.
Add the $999 Voigtlander 17.5mm f0.95 and more modest $199 Sigma 19mm f2.8 DN Art series lens to the mix (both untested at the time of posting), and it’s understandable Panasonic felt the need to refresh the 20mm.
When compared with against rivals with similar focal lengths, the new lens ranks third, surprisingly, behind the original model and the Olympus M. Zuiko 17mm f1.8 although it outperforms the latter lens in overall image sharpness.
