Panasonic Lumix G 14mm f/2.5 ASPH. Lens for MFT (Micro Four Thirds) {46}

Panasonic 14mm f/2.5: the pancake prime built for Micro Four Thirds.

At 21mm long and 55 grams, the 14mm f/2.5 ASPH disappears into a jacket pocket and nearly disappears on the camera body itself. That 28mm full-frame equivalent focal length hits a sweet spot for street, travel, and documentary work, giving you enough width to work in tight spaces without the distortion of a true ultra-wide. The f/2.5 maximum aperture is workable in low light, and the 7-blade rounded diaphragm keeps out-of-focus backgrounds smooth when you're shooting closer to the 18cm minimum focus distance.

Six elements across five groups, including three aspherical elements, keep the optical formula compact without sacrificing correction. Internal focus means the front element stays put during AF, so a 46mm polarizer or ND filter won't rotate out of position mid-shot. The micromotor AF is quiet enough for video use, and full-time manual focus override is always available without flipping any switches.

This lens has been a proven cornerstone of the Micro Four Thirds prime kit since 2010, pairing naturally with the 20mm f/1.7 and the 45mm f/2.8 Macro for a three-lens travel setup that weighs almost nothing. For that kind of shooting, the weight-to-usefulness ratio is difficult to beat.

Who It's For

Travel photographers keeping pack weight down will appreciate that 55-gram figure more after the third day of walking. Street photographers benefit from the 28mm equivalent field of view and f/2.5 aperture for available-light work without drawing attention. Mirrorless video shooters running GX or G-series bodies will find the internal focus and quiet micromotor useful for run-and-gun documentary work. Micro Four Thirds shooters building out a small prime kit get a wide-end anchor that genuinely fits in a shirt pocket alongside the camera.

FAQ

What's the full-frame equivalent focal length?

28mm. On Micro Four Thirds' 2x crop factor, the 14mm sits in the sweet spot between standard and wide, letting you work in tight spaces without the barrel distortion of a true ultra-wide.

How close can you focus?

18cm (7.09 inches) minimum focus distance, with 0.1x maximum magnification. You can get close enough for environmental portraits or detailed still life without macro capability.

Will a polarizer or ND filter stay in place during autofocus?

Yes. Internal focus means the front element doesn't rotate, so filters mounted on the 46mm thread stay locked in position throughout AF and manual focus operation.

Is this lens sharp enough for documentary and street work?

The optical formula uses six elements across five groups, including three aspherical elements. Distortion and chromatic aberration are well-controlled across the frame - the lens has proven itself in the field since 2010.

How does the autofocus perform for video?

The micromotor AF is quiet and smooth enough for video use. Full-time manual focus override is always available without any switch activation, so you can pull focus manually at any point.

Can you use this with the 20mm f/1.7 and 45mm f/2.8 Macro as a travel kit?

That's exactly how it's designed to work. The three lenses together weigh almost nothing and cover street, travel, and close-focus shooting - a modern three-lens kit in the style of classic rangefinder camera kits.

Does it have image stabilization?

No. At 21mm long and 55 grams, size and weight take priority. At f/2.5, you'll need to manage shutter speed in low light, or pair it with a stabilized body like the GH series.
