Sony FE 100-400mm f/4.5 GM OSS

Sony's constant-aperture G Master telezoom: f/4.5 across 100-400mm, internal zoom so the balance never shifts, four XD linear motors (Sony quotes AF up to three times faster than the older f/4.5-5.6 GM) and Optical SteadyShot. 1,840g, dust- and moisture-resistant, with four focus-hold buttons, a limiter, a bearing tripod collar and a 40.5mm drop-in filter slot behind the 95mm front thread. Takes Sony's 1.4x and 2x teleconverters.

📝 How suitability scores are calculated GearScore™ genre scores are calculated from this camera's verified specifications — autofocus, sensor, weight, weather sealing and more — weighted by what matters for each type of photography. Where a spec sheet misses something (e.g. a manual-focus rangefinder for street), we apply a documented editorial adjustment. Scores are not based on customer reviews. See our full methodology →
