The FE 28mm f/2, the smallest of Sony’s latest round of FE lenses, is well worth considering, as Andy Westlake finds out
Sony FE 28mm f/2 with Ultra-Wide adapter: Resolution
Our tests show that the Sony Ultra Wide Converter gives distinctly soft results wide open, but is much better at smaller apertures. Peak sharpness is achieved at f/5.6 through to f/11, although the edges of the frame never quite catch up with the centre. Stopping down further induces diffraction softening, especially at f/22.
