Your new eye for the vast expanses of the Engadine – feather-light and unwavering
A new era of super-telephoto photography begins – light and uncompromising.
With the Sony FE 400mm F4.5 GM OSS (SEL400F45GM, EAN 4548736175662), Sony introduces the world's lightest 400mm F4.5 full-frame prime lens in its class. G Master sharpness, Optical SteadyShot, and a weight of just 994 grams without the tripod foot. Precision and speed on a completely new level. Ready to use immediately. Sharp at every moment. Innovation that changes the way you see things.
Imagine: You're standing in the first light above Sils, a bearded vulture circling over the Roseg Valley. You simply raise the camera to your eyes. No heavy tripod. No hesitation. 400mm G Master resolution, held steady handheld. The Dual XD Linear Autofocus keeps the bird in focus, even at 120 frames per second. The plumage is razor-sharp, the background dissolves into a soft, rounded bokeh.
You no longer have to choose between reach and portability.
The Sony FE 400mm F4.5 GM OSS gives you both: instant clarity and stable freedom, right out of the box. At just 242mm in length and 108mm in diameter, it's closer to a 70-200mm than a classic super-telephoto lens. Perfect for long tours through Val Fex, wildlife in the Stazerwald forest, or ibex on the Fuorcla Surlej. Unwavering performance. Effortless clarity. Legendary G Master optics.
