The new Sigma 45mm f/2.8 DG DN C Lens reviewed and tested on both Sony full frame and APS-C cameras. Is this your next street photography lens or will it’s blurry close focusing problems turn you away?

Available for just $549, and sitting in Sigma’s Contemporary lens lineup, the 45mm f/2.8 is available for both the Sony E-mount and the L-mount (for Panasonic, Sigma and Leica cameras). The lens can be used on any Sony, Panasonic, Sigma or Leica full-frame mirrorless camera. So far, there have been no announcements regarding whether the Sigma 45mm f/2.8 will also be made available in R (Canon) or Z (Nikon) mounts.

The 45mm f/2.8 features a physical aperture ring, which many will appreciate. It can be positioned from f/2.8 to f/22 in third-stop increments. But, if you’re not happy with using an aperture ring, then you can use the ‘A’ setting to switch the control back to the camera body.

Vignetting and distortion might be a slight issue with the Sigma 45mm f/2.8. Also close focusing can lead to some glowing images. Other than that the lens performs very well optically. When taking photos at its maximum aperture of f/2.8, the lens is already clear and sharp at medium to far distances.
