The other week I bought my first third party lens for my growing m4/3rd kit, namely Sigma’s 30mm F2.8 lens.Now I was tempted by the Sigma for a number of reasons. Firstly this lens is a prime lens ( I prefer primes), the 30mm focal length equates to 60mm on my Olympus OMD EM5 (a useful short telephoto length), its small (matching my petite Olympus), it’s moderately “fast” (ie F2.8) but above all it offers great value compared to some of Panasonic and Olympus own brand prime lenses.
So how is it? Well rather good is the short answer. It produces reasonably “sharp” images across the m4/3rd frame, you can blur backgounds to a reasonable extent but above all it seems to perfectly complement my Olympus EM5 and would be perfectly at home on say a Panasonic G3/5 or GX1. This Sigma lens represents great value and I look forward to other Sigma releases in the m4/3rd format. To see some images captured with the Sigma 30mm F2.8 lens (m4/3rd fit) have a look at my Flickr photostream: http://www.flickr.com/photos/26747591@N08/
