Get Sony FE 28mm f/2 at B&H Photo.
A lens can be made small and light and offer very good performance, but something has to give, and typically distortion is allowed to grow.
This “distortion compromise” is indeed the case with the Sony FE 28mm f/2, whose distortion is pronounced. Correcting it will be all but mandatory for many shooting situations.
And yet, correcting its distortion substantially degrades image sharpness in the areas that must be stretched.
Two examples are shown with toggles for distortion uncorrected vs corrected, and with a large crop also.
