Verdict

The Lumix S 100mm 2.8 Macro is a welcome addition to the L-mount system, delivering sharp results across the frame, near and far. In my tests it was equally sharp whether shooting landscapes at infinity, portraits from a meter or so, or right up to its closest focusing distance. 

With the subject around 11cm from the tip of the lens, you’ll achieve life-size 1x magnification, again with sharp details and minimal distortion.

It’s not the only game in town for L-mount owners though, as Sigma’s older 105mm f2.8 DG DN also delivers 1x magnification on full-frame bodies from a similar focal length with the same aperture, and a lower price. 

I’ve not tested the Sigma so can’t comment on the quality, but the Lumix lens is comfortably shorter and less than half the weight, making it a much more portable proposition, not to mention a more consistent match for the existing Lumix S primes. 

Compare them closely, but one thing’s for certain: the Lumix S 100 f2.8 Macro delivers the goods at all distances with an impressively compact form factor. Highly recommended for L-mount owners who want a great quality macro lens which also doubles as a decent portrait and short telephoto option.
