I did use the lens during a couple of light drizzles without any issues, and I believe it can withstand some rain. Unfortunately, my experience with the lens’s weather sealing is somewhat of a mixed bag. Sony’s own illustrations suggest that the lens barrel and switches all have seals and in theory, the lens should hold up well under inclement weather. A quick look at the back of the lens shows a rubber gasket around the bayonet mount, which ought to protect both the back element of the lens and sensor of the camera from moisture.
It feels confident in the hand with its robust magnesium-alloy barrel construction that is weather sealed throughout.

Compatible Format(s): Full Frame, APS-C.Minimum Aperture: f/32 at 100mm, f/40 at 400mm.I obtained a copy of the lens to test out with the Sony Alpha 9 body and I have been able to put it through its paces on a wildlife photography trip to Mexico. The lens’s specifications show that the FE 100-400mm f/4.5-5.6 GM is intended as a professional-grade telephoto zoom and it comes with a matching price tag of $2,499. The lens also features optical image stabilization (said to reduce camera shake by up to five stops), dust and splash-proof barrel, customizable focus-hold buttons, a stiffness adjustment for the zoom ring, and is compatible with both the SEL14TC and SEL20TC teleconverters. The FE 100-400mm f/4.5-5.6 GM features Sony’s sonic-type (Direct Drive SSM) motor for fast and silent autofocus with a minimum focus distance of just 0.98m. The 22 element / 16 group optical design includes one Super ED and two ED glass elements to minimize chromatic aberration while maximizing resolution. Complementing the small form-factor of Sony’s A7 and A9 mirrorless bodies, the lens measures a compact 94x205mm and weighs just 1395g. As part of the Sony G Master lens lineup, the FE 100-400mm f/4.5-5.6 GM aims for high resolution across the entire zoom range, fast and accurate focusing along with high-quality bokeh. The wide end of the range is great for close wildlife and environmental portraits while the longer end is great for mammal and large bird photography. Wildlife photographers will be especially satisfied with the release of this lens as the 100-400mm focal length range is one of the most useful for general purpose wildlife photography. With the introduction of the Sony FE 100-400mm f/4.5-5.6 GM, Sony has released a lens that covers a very useful focal range that can appeal to a wide range of photographers. The last couple of years has seen Sony release some beautiful lenses for their full-frame mirrorless cameras, but a glaring hole remained at the telephoto range of the lineup. Announced alongside the Sony Alpha 9 body last year, the Sony FE 100-400mm f/4.5-5.6 GM is a crucial addition to Sony’s expanding full-frame E-mount lineup.
