Panasonic's first Leica-branded lens for Micro Four Thirds is a tiny internal focusing macro capable of true 1:1 magnification. Like its sibling it fits a lot into a very small space; the 45mm measures just 2.5" in each dimension, yet manages to to incorporate optical image stabilization. This lens can focus to just 0.15m without changing in length - a feat made possible by a complex internal focusing system which uses three groups in a floating arrangement. Optically it's very good indeed, but the image stabilization system isn't the most effective especially at macro distances.

In many regards the Leica DG Macro-Elmarit 45mm F2.8 ASPH is a very appealing little lens, and its diminutive size captures the gestalt of the format perfectly. Optically it is, if not quite top of the class, still very competent indeed - and the 1:1 magnification offers intriguing creative possibilities.
Good for: True 1:1 macro work, where this lens's strengths really shine.
Not so good for: Everyday photography, where the somewhat ineffective O.I.S. stabilization and relatively slow maximum aperture are limiting.
