The Big Third Party Autofocus Lenses Roundup: Viltrox 75mmF1.2 and 13mmF1.4, Tamron, Sigma and TTartisan


Until just a few years ago, I’d have never thought I would ever be able to make a roundup dedicated only to third party autofocus lenses for Fujifilm X mount.

But luckily Fujifilm understood its error in 2021 and fixed it, so here we are, in 2023, with lots to cover!

The autofocus lenses we will cover below are:

    – shapely, very solid barrel made of metal,
    – excellent image quality in the frame centre from f/2.0 upwards,
    – imperceptible longitudinal chromatic aberration,
    – slight lateral chromatic aberration,
    – lack of any serious distortion problems,
    – blurry areas pleasing to the eye.
    – weak image quality in the frame centre near the maximum relative aperture,
    – not especially sharp edges of the frame,
    – problems with spherical aberration,
    – very high coma,
    – distinct vignetting,
    – weak performance against bright light.
