Frequently asked questions
Does the Sigma 14mm f/1.8 DG HSM Art take filters?
No. The front element is curved and protrudes, so screw-in filters do not fit and a dedicated holder system would be needed.
Is the Sigma 14mm f/1.8 DG HSM Art good for the Milky Way?
Yes. f/1.8 at 14mm is popular for Milky Way work and Sigma designed it with good coma control in mind.
Is the Sigma 14mm f/1.8 DG HSM Art heavy?
Yes. At about 1.2 kg it is heavy for a 14mm prime, which is the trade-off for its f/1.8 aperture.
