The Sigma 19mm F2.8 DN is a wide angle lens designed exclusively for mirrorless interchangeable lens cameras and has the equivalent angle of view as a 38mm (35mm equivalent focal length) on the Micro Four Thirds systems and 28.5mm (35mm equivalent focal length) on the E-mount systems. This lens benefits from a newly developed linear AF motor which moves the lens elements directly without the need for gears or the drive of other mechanical parts. This system ensures accurate and quiet autofocusing, making the lens suitable for video recording as well as still photos. This lens has a minimum focusing distance of 20cm/7.9in, making it useful for relatively close-range work.

Buying my first prime ever, which one would it be?
Hi, Got my nex6 with 16-50 kit before a month (my first pro-camera), I'm pretty happy with it, doing my first steps into the photography world, reading books, blogs and striving to output amazing shots :) However, I was at a party few days ago, it was in a very dark room and all my shots were very grainy and soft, probably because of the relative slow lens (at ISO3200 and minimum aperture 3.5 I had to shot with slow shutter 1/10 which is definitely not intended for moving objects, when I raised the ISO to 6400 pictures became grainy). Shooting in dark places is not my main concern, that was an extreme situation but I often find myself in a situation where a faster lens could make the difference. So, aiming for my first prime... I examined all the photos from the party and notices that most were shot in FL between 16-24mm, I guess that means that I tend to shot in wide zoom. Consequently, I considered Sigma 19mm as my preferred option, however I'm not sure regarding the following: 1. ...
Agreed. You should have used the flash in that situation. Yes, f/2.8 will work, so does the FL of 19mm - it is nice and wide for indoors. Your ISO3200 f/3.5 shot will not change much if you go to f/2.8. However, if you zoom, the 18-50 kit will be at f/4 or smaller. Then f/2.8 is a full stop faster. You will still be at ISO3200, but now at f/2.8 and 1/20th, as opposed to f/4 and 1/10th. It will work for still objects, not always with people. I would consider the flash, putting up some more lights, or a lens that is f/2 (getting you to ISO1600 and 1/20th). It is a wide lens, so 1/FL matches 1/20th. You should be able to master that. But, as mentioned in another thread, for pixel-level sharpness, 1/30th or 1/40th may be preferred. Yes, exactly. For a party, the E20 lens may work even better, as it makes the camera a lot less noticeable (looks more like a P&S). It is f/2.8, same as Sigma 19, but a bit more expensive. The E35 lens is a better choice, at f/1.8, but has a narrow FOV. I ... Continue Reading
Sony SEL20F28 on NEX 7 and color cast?
Has anyone used the new SEL 20F28 on the NEX 7? Magenta cast or not; it is a pancake after all ... Worse or less color cast in the corners than the Sigma 19 2.8 E mount lens? I would like to know what you have experienced here in order to understand which of these two might be (more) color cast free, if any ....
I have seen these issues with the Sigma twins. 1 Pink cast on both but can be cleared by custom WB. 2 Bad purple and green fringing on the edges (even at 5.6) can be cleaned in LR but leaves disturbed area artifacts. Worse on the 19, very little on the 30. 3. I am starting to doubt micro contrast on the Sigma 19mm despite its ability to out resolve and be flatter than the Zeiss 21 2.8. Sony OSS kit and 50 have good color IMHO. Continue Reading
