The Panasonic Leica DG Macro-Elmarit 45mm f/2.8 ASPH. MEGA O.I.S. is a 1:1 macro prime for Micro Four Thirds cameras, co-branded with Leica under the DG (Digital designed) Macro-Elmarit designation. MEGA O.I.S. provides in-lens optical stabilisation. Micro Four Thirds mount.
f/2.8 maximum aperture. 45mm focal length (approximately 90mm equivalent on MFT). 1:1 maximum magnification. ASPH. (aspherical elements). MEGA O.I.S. (in-lens optical image stabilisation). Leica DG branding. 46mm filter thread. Autofocus. Micro Four Thirds mount.
The Leica DG branding indicates Panasonic lenses developed with Leica oversight for optical quality standards — these are Panasonic-manufactured MFT lenses with Leica's design involvement. The MEGA O.I.S. provides stabilisation independent of body IBIS, useful on MFT bodies without IBIS or for combined optical + body stabilisation. The 90mm equivalent and 1:1 macro capability suit insect, botanical, and product macro on MFT cameras.
On the used market the Panasonic Leica DG Macro-Elmarit 45mm f/2.8 MFT is an affordable 1:1 macro prime for Micro Four Thirds cameras. Condition checks: O.I.S. engagement (listen and test), AF response across macro focus range, 46mm front element for marks, focus ring smoothness across macro travel.
