What type of mount does this lens have?
This Sigma lens has a Nikon FX mount, designed for Nikon full-frame cameras. It is also compatible with Nikon APS-C sensor cameras, although in that case the angle of view will be narrower.
Is it suitable for low-light photography?
Yes, thanks to its maximum aperture of f/1.8, this lens allows capturing images in low-light conditions without needing to use flash or tripod, making it ideal for night or indoor photography.
What is the minimum focusing distance?
The minimum focusing distance is 0.2 meters, allowing you to get quite close to the subject for close-ups with a wide-angle effect.
Does this lens have image stabilization?
No, this lens does not incorporate image stabilization. However, its large aperture helps compensate for the lack of stabilization in low-light situations, and many modern Nikon cameras include in-body stabilization.
