Sony SEL100F28GM 100mm f/2.8 GM Lens - Telephoto Prime

The Sony SEL100F28GM 100mm f/2.8 G Master lens occupies a singular position in Sony's lineup as the only E-mount lens featuring Smooth Trans Focus (STF) technology. At its heart is an apodization optical element—a special filter that gradually reduces light transmission from center to edge, smoothing the transition between in-focus and out-of-focus areas in a way that no aperture blade design or software processing can replicate. The result is bokeh that appears remarkably natural and creamy, with defocused highlights rendered as soft, evenly illuminated circles free of hard edges or distracting ring patterns. Combined with G Master-level resolution, the lens produces images where the subject snaps into sharp focus against a background that melts away with unusual grace.

The 11-blade circular aperture further contributes to the quality of out-of-focus rendering, maintaining round highlight shapes even when stopped down. Sony's DDSSM (Direct Drive Super Sonic Motor) autofocus system delivers fast, accurate, and nearly silent performance that suits both portrait sessions and video work. Built-in Optical SteadyShot stabilization adds versatility in lower light or when shooting handheld at slower shutter speeds. The lens focuses down to 0.57m with 0.25x magnification, opening up close-up and detail photography possibilities. It is worth noting that the apodization element does reduce effective light transmission to approximately T5.6, so photographers accustomed to shooting wide open at true f/2.8 exposure levels will need to compensate with ISO or shutter speed adjustments.
