Dustin Abbott A high performing, reasonably priced option.[...] it will lose some buyers to the Samyang and Viltrox either for those wanting the larger F1.4 aperture (and the Samyang is a gorgeous portrait lens) or a lower price point (the Viltrox is a LOT of lens for the money).[...] It’s got excellent autofocus, good image quality, and it is a first party lens.
Phillip Reeve Very good sharpness already wide open in the center and outstanding sharpness when stopped down to f2.8 across the whole frame as well as no distortion at all [...] The build quality is solid, the user interface of the lens is useful and the AF operation in general feels very satisfying. The lens shows some chromatic aberrations wide open. LoCA itself is not that bad, but the lens suffers from purple fringing at large apertures which also appears in the focal plane
