For wildlife trackers, birding enthusiasts, and action photographers, carrying heavy glass into the field has long been a necessary tax on performance. Tripods, heavy monopods, and cumbersome gear setups often mean the difference between getting the shot and missing a split-second moment of unpredictable action.

Today, Sony officialises a massive leap forward for handheld outdoor photography with the double announcement of two groundbreaking G Master super-telephoto prime lenses: the Sony FE 400mm F4.5 GM OSS (SEL400F45GM) and the Sony FE 600mm F6.3 GM OSS (SEL600F63GM).
