An update to the original Panasonic Lumix 20mm f/1.7 ASPH. lens, the new model offers the same optical performance as the original lens, but features a new design, including updated metal design, improving over the plastic parts on the old model. We compare the two to see if there are any additional benefits with the new lens.

Panasonic Lumix G 20mm f/1.7 II Pancake Handling and Features

The new Panasonic Lumix G 20mm f/1.7 II is designed to maintain the impressive performance of the original Lumix G 20mm f/1.7 ASPH. lens. The new Lumix G 20mm f/1.7 II ASPH. lens is extremely compact and lightweight with a bright f/1.7 aperture that enables beautifully soft focus on the background for the subject to stand out. The 20mm Micro Four Thirds lens is equivalent to 40mm on a 35mm film camera and works on all Panasonic and Olympus Micro Four Thirds system cameras.

Key Features

• Metallic profile
• Finished in black and silver
• Reliable metal mount
• Multi-coated lens elements
• Seven lenses in five groups
• Two aspherical lenses
• Circular aperture diaphragm

Another difference is the weight of the new lens vs the original, with the new lens weighing 100g compared to 87g for the original, with both being very lightweight lenses.

Value For Money

The Panasonic Lumix 20mm f/1.7 II is available for around £349 vs £269 for the old model making the older model better value for money while it is still available, although it's possible that the price of the new model may drop. The 20mm f/1.7 lens is brighter than other 20mm pancake lenses for other systems, eg the Sony NEX 20mm f/2.8 (around £300) and Samsung NX 20mm f/2.8 (around £160). This makes it good value for money for a bright compact prime lens.

Other prime lenses for Micro Four Thirds that you could look at include the Panasonic Lumix 14mm f/2.5 pancake available for £145, the Olympus 17mm f/1.8 for £399, the Sigma 19mm f/2.8 for £149, and the Panasonic Leica DG Summilux 25mm f/1.4 for £439.

Panasonic Lumix G 20mm f/1.7 II Pancake Verdict

The Panasonic Lumix G 20mm f/1.7 II with a redesigned styling and metal parts, and this gives a very slight improvement in resistance to flare, as well as a slight improvement in contrast. The redesign has very slightly improved the position of the surrounding plastic closest to the lens, which results in a very slight improvement in shielding light from hitting the lens at oblique angles.

The improved build quality should make the lens last longer, although unfortunately there has not been an improvement in focus speeds with both the old and new lens giving the same focus speeds in our testing. With the same excellent image quality, reasonable value for money, and compact size, this new model should be just as popular as the original and is an excellent choice for Micro Four Thirds users. The new colour options also better match the new cameras from Panasonic and Olympus.

The Panasonic Lumix G 20mm f/1.7 II gives excellent image quality and improved build quality.
