This months What Digital Camera Magazine tested the two new wonderfully small Sigma primes lenses designed for the Panasonic “G” series m4/3rd cameras, Olympus’s PEN system and Sony NEX compact camera system.The lenses were tested on a m4/3rd camera body.The Sigma 19mm F2.8 EX DN and Sigma 30mm F2.8 EX DN shows just how well Panasonic / Olympus’s m4/3rd system is developing.There are now a large number of high quality optics to complement the most recent m4/3rd camera bodies.
The results? REALLY impressive. Not only are both lenses wonderfully petite but the MTF (i.e. sharpness) figures are wonderful, especially for the 19mm lens which gives pin sharp results right across the frame.Now throw into the mix that they are both available for well under £200 and they begin to look like a real bargin.
The Sigma 19mm F2.8 EX DN equates to 38mm on a “G” series micro 4/3rd body like the Panasonic G3 or GX1,whilst the 30mm becomes a useful reasonable “fast” 60mm short telephoto, perfect for street photography.I’ve been so impressed I’ve ordered the 30mm myself and only the fact I already own the Panasonic 20mm F1.7 stops be getting the 19mm Sigma.
