Sigma 19mm f/2.8 EX DN for Micro Four Thirds (M43)

The Sigma 19mm f/2.8 EX DN is a budget-conscious auto-focus prime for the Micro Four Thirds camera system. Sigma lenses are generally known to be a hit or miss; therefore I wasn’t instantly drawn to it when they recently introduced line of lenses for the M4/3 system. But the reviews for this particular model were fairly positive. So I figured $150 or so was worth the risk.

My initial reaction was very positive. The build quality and fit is fairly decent. However, the Sigma 19mm 2.8 is quite bulky for a mirrorless prime. My Samsung NX 20mm 2.8 is less than half the size of the Sigma.

I read that this lens could take up to 3 or 4 seconds to index on some Micro Four Thirds cameras. But I didn’t experience any long indexing issue on my Lumix GF2. The lens and the camera was ready to use instantly upon powering up. The auto focus is surprisingly quick, produces pleasing bokeh, and the picture quality is actually quite good. The minimum focus distance is short (0.2m) which can be useful.

Normally, not much is expected from a lens at this price range. So you’d be pleasantly surprised once you discover how well this cheap Sigma performs. I’d say it’s well worth the price; it comfortably outperformed all of my expectations. Looks like this Sigma is a hit.
