Sigma’s super-sharp 35mm f/1.4 Art now stands quite surpassed by its mirrorless successor, the just-launched-this-morning Sigma 35mm F/1.4 DG DN | A. The MTF charts show a noticeably-sharper lens, especially at the edges of the frame, and one with less astigmatism.
The lens looks to be very close to the image quality of the bonkers-class Sigma 35mm f/1.2 lens made for E mount.
That said, Gerald Undone’s review of the lens indicated it was not at all sharp at the closest focus distance. Worse, it appears to have significant color aberration (CA). His review conflicts a bit with the review done by DPReview TV, which noted the CA, but found it untroublesome and considered the lens to be super sharp.
Gordon Laing’s review found the Sigma lens to be good, but not as good as the new Sony G Master equivalent.
The lens will sell for about $900 in mid-May. It will be available only for E mount and L mount.
