SUMMARY
Sony has introduced a new G Master 400mm f/4.5 lens that weighs less than a kilogram, making it comparable in weight to a standard 70-200mm zoom. This lighter design allows for greater mobility and extended shooting sessions without a monopod, particularly beneficial for motorsport and wildlife photographers. While the 600mm sibling offers more reach, the 400mm provides a wider angle of view that aids in tracking erratic subjects, with the option to crop in post-production. The lens features advanced optical elements and an 11-blade aperture, and it is compatible with Sony's teleconverters.
