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.”

There are NO BETTER LENS for $199 – Just Amazing!
“While “bokeh” taste maybe subjective, most would agreed upon that (1) Big-Round shaped bokeh highlight is more pleasant than Elliptical-shaped-Cat’s-Eyes highlight, and that (2) Smooth + Soft color transition is better than Harsh-Edge lines. Sigma 19mm delivers on both counts.” – By Peter Yang

Sharp. Good illumination across frame. Quick, accurate AF that is very quiet. A bargain wide/normal lens
“Good sharpness across the frame. Fast and accurate AF with very quiet operation. A very good bargain 38mm equivalent for your MFT. The focusing ring is easy to use in MF assist/focusing by wire when filming. A good buy. Not as sharp as a Leica or Zeiss lens but it is quite good especially for the money.” – By P. Snyder

Sigma 19mm M4/3
“I was torn, but I went with the 19mm. Here’s what I’ve experienced so far. The lens a sharp, AF is fast. I like the colors. The lens is light and the balance is very good. I like the hood too.” – By Alfred R. Marzian

Micro 4/3s wide angle on a budget
“At $199.00 for a 19 mm f2.8 lens you can’t really beat the price… The build quality is very good especially considering the price point. The focus ring is smooth and dampened a bit as well. Given adequate light the lens is nearly as fast focusing as the current Panasonic lens and maybe just a bit slower than the lens mentioned above.” – By Wayne Howarth

Great lens on my Panasonic G3
“This is a great lens. Close focus is unbelievable, 100% crop is crystal clear. I’ll put a rose picture in the pictures above that is 100% crop and you can see for yourself. Light in weight, fast enough, great little prime for my favorite camera.” – By R. Davenport

Sharp, could be faster
“You still only get 38mm (if you want on the other end of 50 you can spring for the 30mm), and wide open aperture is a respectable but not impressive f/2.8. The lens, at least my copy, is very sharp at wide open so it’s pretty useable for casual shooting without the flash, but you’ll have to crank up the ISO and get into noise since you’re missing a few extra stops of aperture.” – By Andrzej Wierzbicki

Sigma 19mm F2.8 EX DN Features

The Sigma 19mm F2.8 EX DN comes with a newly developed linear AF motor for swift and accurate autofocus, making it ideal for video as well as still photography.

The lens construction utilizing three glass mold aspherical lenses deliver excellent correction for distortion, color aberration and field curvature. While the inner focusing system corrects the fluctuation of aberration to maintain image quality regardless of the focal distance. It also equipped with Multi-layer coating reduces flare and ghosting, and provides sharp and contrasty images even at the maximum aperture. Not only does it, the 7 blades of the diaphragm produce a pleasing quality in the out-of-focus areas of an image (bokeh).
