Review on Sony Full Frame Large Aperture Ultra Wide Angle by James Vachon

Already a month. To be honest, complaining about the lens would sound more like a crybaby than anything else. Autofocus is quiet and lightning fast and only struggles on dark or flat surfaces when continuously tracking photos, otherwise no issues. The sharpness is superb and if you google the image quality of this lens you will see for yourself. The images here may not convey true image quality results for this type of lens, so you'll need to find some full-size sample images to see them. Pros: GM features in a G body, so this lens is definitely worth $800. .Light Almost straight line Excellent auto focus Super sharp Good contrast Cons: Possibly a light issue, it tends to defocus in low light and on flat surfaces where there is nothing to focus on.
