A fast, versatile prime, this 30mm f/1.4 DC DN Contemporary Lens from Sigma is designed for use with APS-C-format Nikon Z-mount mirrorless cameras. The bright f/1.4 maximum aperture benefits working in low-light conditions and also affords extensive control over depth of field for using selective focus techniques. The optical design features a pair of aspherical elements, along with one high-refractive index element, which significantly reduces spherical aberrations and distortion for increased clarity and definition for notably sharp image quality. Also, a Super Multi-Layer Coating has been applied to control lens flare and ghosting in strong lighting conditions. Additionally, benefitting both stills shooting and video recording, this compact prime also incorporates a stepping AF motor for smooth, near-silent autofocus performance. A rubber sealing at the lens mount helps protect against dust and other elements entering the lens or camera.

Q: 2. If I'm looking for a good prime that can be used well for both portrait and landscape, is this a good choice?

A: Yes. I am very happy with this lens. I have a bevy of lenses including Leica, Nikkor, Zeiss and so forth and the sharpness and contrast in this lens is exceptional. I have used it for both landscapes (especially multi-image stitches) and portraits. It's superb on a Lumix GH5 and GX8.

Q: 3. Hi! What I don't get, it's if I use it on my a6500 I'll be a 30mm lens or 45mm. Thanks!

A: It will be a 30 mm crop sensor lens on your a6500. To get the same view on a full frame camera like the a7 series, you would use a 45 mm full frame lens. You should find the lens very sharp and useful on your 6500 although the colors would need to be increased slightly in post processing.

Q: 4. Is this good for street photography? I'm looking at a 25mm but this looks good as well, is 30mm too narrow?

Q: 5. Is this one reversible?

Q: 6. How fast is the auto focus for video?

A: This lens does have a very fast auto-focus. The speed is also determined by the camera itself. Make sure that the settings are set for faster auto-focus as well for the best usage.

Q: 7. I wonder how much vignetting the lens will produce on the A7 series... Any guess?

A: None if you use it on APS-C mode, switching to full frame mode will render it useless, however.

A: The lens is very new and there are not very many real life reviews.Till more reviews come out it is very hard to be sure but from the specifications and the small reviews that are out it seems to be a good lens with very little CA.

Q: 10. Does this lens resist cold or hot well?

A: I went to Iceland in April and it was pretty cold. This lens was on the camera 90% of the time 2000 pics. The lens held up well against the cold and light rain. Be aware that I was using a rain cover to protect the lens and a6000 during significant down pour. I was little paranoid that one day I will wake up and see condensation on the inside but it never happened... Even when I didn't take extreme care to acclimate the lens when going from cold outside to warm inside. After 2 yrs it is still going well. Focus is smooth as ever and focus by wire mechanism is also very smooth.
