Sirui's store page for the Swift 20mm f/2.4 and 40mm f/2.2 autofocus lenses now says "Expected to ship from November 18." PetaPixel reported on Oct. 29 that the lenses were expected on Nov. 6.

What Sirui's store says

Next to the date, the page carries an apology: "We sincerely apologize for the delay and would like to offer you a free gift with your order." The gift applies to orders placed by Nov. 12, 2026. Sirui's page does not say what the gift is or why the lenses are late.

Price and availability

  • Price: $149 each, per PetaPixel, which cited Sirui's announcement. Sirui's store page showed a Pakistani rupee price when we read it, so we are not using it as a U.S. price
  • Sirui store: ships from Nov. 18, per its product page
  • B&H, 40mm f/2.2 in Sony E mount: $149, Add to Cart, listed as in stock
  • B&H, 40mm in L-mount and 20mm in Sony E and L-mount: preorder, expected Dec. 11, 2026
  • Fujifilm X: Sirui's store lists X-mount versions. We found no X-mount listing at B&H

Mounts

Sirui's store offers both lenses in Sony E, L-mount and Fujifilm X. There is no Nikon Z option on the page. PetaPixel also lists E, L and X, covering full-frame Sony and L-mount bodies and APS-C Fujifilm X cameras.

Key facts

  • Focal lengths: 20mm f/2.4 and 40mm f/2.2, full-frame autofocus primes

  • Size: about 60 to 62.3mm long, with a 58mm filter thread
  • Optics: 11 elements in nine groups for the 20mm and 11 in eight groups for the 40mm, with nine aperture blades

Why it matters

At $149 each, the price is the draw. If you want one now, B&H's 40mm in Sony E mount is the only version we found in stock.

Buyers at Sirui's store wait until Nov. 18, and B&H's other four versions are expected Dec. 11. Imaging Resource reported the lenses as available through Amazon and Sirui's website; we did not check Amazon.

Other recent lens launches include Sigma's 50-120mm F2.8 APS-C zoom and Tamron's 16-50mm F2.8 APS-C zoom.

More launches are in our lens news hub.
