Summary: The only macro as sharp with a better depth of field as this one was my 110mm Hasselblad on a bellows. I have shot dozens of hand held macros with room light using this lens on my new G4. You hear this slooow shutter sound and you think in your mind "no way" but then you look at the pictures!
Summary: Pros: Great sharpness and color Leica Contrast Nice looking bokeh OIS Macro and Portrait in one Cons: Vignetting at f2.8 noticeable Lens will often not attempt to focus on macro subjects unless you AF on your hand or manual focus into macro range first No focus limiter option for macro only range...

Summary: Purchased this specifically for Macro work for my Panasonic Lumix G6. The lens documentation suggested a firmware upgrade on the camera might be needed for maximum compatibility with the lens.
Summary: MY EXPERIENCE > There is no doubt that the Leica DG Macro-Elmarit 45mm F2.8 Macro is an excellent lens--indeed I purchased a Lumix GX7 system largely to be able to use this lens, largely based on a 20-year love affair with a Vivitar 90mm f2.8 macro (90mm in 35mm format = 45mm in M4/3 format).
Up to the moment it failed I was quite pleased with the lens

Summary: Panasonic will not repair, for free, an 18 month old $900 lens that simply stopped focusing. Numerous other people report the same problem on a not widely purchased lens (i.e. DPREVIEW). This lens obviously has some sort of defect which the company will not acknowledge, or remedy.
