Sigma 19mm F2.8 EX DN Reviews

Photographyblog reviews the Sigma 19mm F2.8 EX DN and writes;
“For this test, the Sigma 19mm f/2.8 EX DN lens was attached to a Panasonic Lumix DMC-GF3 body, which in turn was mounted on a sturdy tripod. Exposure delay mode was activated. Tonal and colour variances across the crops are due to changes in natural light during the session. Centre sharpness remains high through from f4 to f/11, with f/16 and f/22 being adversely affected by diffraction. The edges aren’t nearly as sharp as the centre, with f11 producing the sharpest results.”

Ephotozine reviews the Sigma 19mm F2.8 EX DN and writes;
“This compact lens should make an ideal addition to any Micro Four Thirds or Sony NEX camera kit. Its light weight, compact size and excellent optical performance are complimented by fast auto focus speeds and good build quality. With the price sitting at around £170, this lens represents excellent value for money also.”

“As a new entrant into the NEX market segment, Sigma is certainly doing quite well. Sigma 19/2.8 EX DN is the company’s second solid offering (the first one was 30/2.8 EX DN) for this system… Sigma 19/2.8 does a lot of things right – price, resolution, color are all things that, while not absolutely remarkable, are done right in this lens.”

Lenstip reviews the Sigma 19mm F2.8 EX DN and writes;
“..On the other hand you get a wide-angle EX series lens at a quite affordable price which can provide sharp images across the aperture range and for most of the frame. What’s more, this lens is optically better and cheaper than such instruments as the Olympus 2.8/17 or the Sony 2.8/16 – from such a perspective it would be difficult to complain.”

SLRGear reviews the Sigma 19mm F2.8 EX DN and writes;
“Mounted on the Panasonic GX-1 m4/3 camera, the lens produces excellently sharp images even wide open at ƒ/2.8. There’s just a hint of corner softness at ƒ/2.8, but even this is all but eliminated by just stopping down to ƒ/4. Stopping down to ƒ/5.6 technically provides more sharpness, but you’d only notice it looking very closely at a test chart.”
