Panasonic's premium MFT standard zoom with Leica-branded optics and fast constant aperture.
The Panasonic Leica DG Vario-Elmarit 12-60mm f/2.8-4.0 ASPH. Power O.I.S. is a premium standard zoom for Micro Four Thirds, launched in 2016. Covering a 24-120mm equivalent range with a fast f/2.8-4.0 aperture, it combines Leica's optical engineering with Panasonic's electronic design. It was bundled with the GX8 and later the G9.
Optical quality is very good with excellent sharpness across the zoom range, minimal distortion, and well-controlled chromatic aberration. The Leica certification means it meets specific MTF performance standards. Power O.I.S. provides robust stabilisation. Build quality is excellent with a metal barrel, weather sealing, and a quality zoom ring.
Micro Four Thirds mount only, 62mm filter thread. Not to be confused with the Panasonic Lumix G Vario 12-60mm f/3.5-5.6 which is a cheaper, slower alternative. The Leica DG version is the premium tier and a genuine step up in both optics and build quality.
Good value used given its optical quality. Check the Power O.I.S. operation, zoom ring smoothness, and weather seal integrity. This is one of the best standard zooms available for MFT and a strong alternative to the Olympus 12-40mm f/2.8 PRO with the advantage of extra telephoto reach.
