Macro prime for Micro Four Thirds

The Panasonic Leica DG Macro-Elmarit 45mm f/2.8 ASPH. MEGA O.I.S. is a macro prime lens designed for Micro Four Thirds cameras. It provides a 1:1 magnification ratio and a minimum focus distance of 5.9 inches for life-size close-up work. The f/2.8 to f/22 aperture range supports depth-of-field control in varied lighting.

Optical elements and stabilisation

One extra-low dispersion element suppresses chromatic aberration and colour fringing across the frame. An aspherical element helps correct distortion while multi-coated surfaces reduce flare and ghosting. The built-in MEGA Optical Image Stabiliser compensates for camera shake during handheld macro shooting.

Internal focus and filter thread

Internal focusing keeps the lens barrel from extending, which helps maintain working distance when lighting subjects at close range. A floating system optimises correction throughout the focus range. The 46 mm filter thread accepts standard accessories and the rounded seven-blade diaphragm produces smooth out-of-focus highlights.

Questions about this item

Will the 46 mm filter thread or 7-blade diaphragm need routine service?

The 46 mm thread and rounded 7-blade diaphragm are passive mechanical parts; they require no scheduled maintenance beyond normal cleaning.

What limits continuous shooting with the MEGA O.I.S. and floating focus system?

The floating focus system and MEGA O.I.S. are designed for sustained use; the first practical limit is the camera body's buffer or heat management, not the lens itself.

How much heat or noise does the internal focusing motor produce during all-day macro work?

Internal focusing and the MEGA O.I.S. unit run quietly with minimal heat; the lens barrel stays near ambient temperature during extended sessions.
