Panasonic's beloved MFT pancake — 40mm equiv at f/1.7 in body-cap-like dimensions.
The Panasonic Lumix G 20mm f/1.7 ASPH. II launched in 2013 as the Mark II of one of MFT's most beloved primes. Providing 40mm equivalent at f/1.7 in near-pancake dimensions, it is the go-to compact prime for MFT street and travel photography.
Optically very good — sharp from f/2.8 with pleasant rendering at f/1.7. The 40mm equivalent provides a natural, slightly-wider-than-normal perspective. Quiet AF motor — improved over Mark I. Aspherical element. One of MFT's sharpest pancake primes.
Micro Four Thirds mount with 46mm filter thread. Weighs just 87g — barely larger than a body cap. No weather sealing. No OIS — relies on body IBIS. Minimum focus distance 20cm. Available in black and silver.
Available used at budget to mid-range prices. One of the most popular MFT lenses — pairs perfectly with compact bodies for a pocketable setup. The Olympus 17mm f/1.8 is slightly wider. The 40mm equiv perspective is natural and versatile. A beloved classic.
