3. Can I update the firmware on this lens?

Yes, the lens is fully compatible with the Sigma USB Dock (sold separately), allowing you to update firmware and calibrate autofocus settings.

4. Does this lens have optical stabilisation?

Optical stabilisation is not specified for this model; it relies on its fast f/1.8 aperture to maintain fast shutter speeds in low-light environments.

With its mid-telephoto range and f/1.8 aperture, it is ideal for portraiture, weddings, events, and indoor sports where light is limited and subject isolation is key.
