Sony Alpha FE 100-400mm f/4.5-5.6 GM Super Telephoto Zoom Lens with Software Suite and Accessory Bundle

Sony Alpha FE 100-400mm f/4.5-5.6 GM Super Telephoto Zoom Lens

The Sony Alpha FE 100-400mm f/4.5-5.6 GM Super Telephoto Zoom Lens is a full-frame super telephoto zoom that provides exceptional sharpness, fast AF and a compact design despite outstanding performance. Like other products in the G Master lens series, this lens has a high standard of resolution. Amateur enthusiasts and professional photographers alike will find the FE 100-400mm GM to be a powerful zoom ideal for capturing sports or wildlife.

High-Performance Image Stabilization

High-performance Optical SteadyShot image stabilization is built right into the lens for sharp, blur-free images with a wide range of subjects and handheld shooting. The stabilization lens is driven by a linear motor for fast, precise compensation. Additionally, 5-axis image stabilization becomes available when used with Alpha series cameras that feature built-in image stabilization

Extraordinary Detail and Bokeh

The Sony Alpha FE 100-400mm GM provides outstanding sharpness combined with smooth bokeh in the same lens. It achieves spatial frequency of 50 lines pairs per millimeter at a lens' widest aperture while simultaneously producing beautiful bokeh. 22 lens elements in 16 groups, including one Super ED (Extra-low Dispersion) and two ED glass elements, help minimize chromatic aberration and provide unprecedented corner-to-corner resolution. The high resolution of this lens helps to enable superior reproduction with high contrast. Sony's Nano anti-reflective coating makes it a great lens for sports or wildlife scenes, minimizing unwanted reflections, flare and ghosting.

Fast, Quiet and Precise Focus

The FE 100-400mm GM super telephoto zoom lens features a double motor system that helps maximize AF performance and keep up with fast-moving action. The Direct Drive Supersonic Wave Motor (DDSSM) drives the heavy front focus lens group, and the Double-linear motor system enables rapid acceleration of the main lens group for capturing sudden subject motion. With high precision positioning control and a newly optimized AF algorithm, the FE 100-400mm GM quickly finds and focuses on your subject.

Professional Operability

This lens is designed for both professionals and enthusiasts who want instant and direct control. Quickly switch between auto and manual focus via the AF/MF focus mode switch on the side, depending on how much focusing control you desire. A focus range limiter switch can either let the lens hunt through the focal range or limit the range from 3m to infinity for faster focusing on distant subjects. There are other switches and buttons for image stabilization compensation and customizable focus hold. Operating this lens is easy for amateurs and pros.

Removable Rotating Tripod Mount

A removable, versatile lens tripod mount lets you quickly remove the camera from a tripod when you need a handheld solution. This mount features a revolving mechanism to let you quickly change between landscape and portrait orientation. It also has a secure lock mechanism to prevent accidental detachment.

9-blade Circular Aperture

The 9-blade circular aperture contributes to gorgeous bokeh in which the subject stands out against a smoothly defocused foreground and background as well as perfectly round points of defocused light. Conventional aperture blades have flat sides creating unappealing, polygonal shaped defocused points of light. Alpha lenses overcome this problem through a unique design that keeps the aperture almost perfectly circular.

Lightweight Design

Photographers or videographers who want a lighter, smaller and more portable option will find it with this super telephoto lens. The FE 100-400mm GM weighs just 49.3 ounces, among the lightest in its class and ideal for Sony's compact cameras.

Sony Alpha FE 100-400mm f/4.5-5.6 GM Super Telephoto Zoom Lens with Software Suite and Accessory Bundle SKU: SEL100400GM-KT1

Rated 2 out of 5 by from not as good as it should be for the money takes too long to focus often, very disappointed, i have all g masters and thought they would be faster and keep focused.

Rated 5 out of 5 by from Sharp, light, and quick AF with 1.4 and 2.0 PCs Excellent lens, sharp and quick AF. Much smaller and lighter for travel than my 200-600. Works great with both the 1.4 and 2.0 TC when there is enough light for the F-stop reduction. Has short minimum focal distance and have used for everything from wildlife to sports, landscape, flower closeup and portrait. Primarily use for travel when I don't carry 2 bodies fitted with other lens. Big disappointment is no zoom lock on external zoom GM lens. Has softer/tighter ring but lens creeps even on tighter setting. I knew this when I bought it but other features offset.

Rated 5 out of 5 by from Great "Bad Boy" Lens Have had for about 5 years. It is truly great. No regrets about spending all the money.

Rated 5 out of 5 by from Great at Every Level I bought this lenses as the 2-600mm became too heavy for my injured shoulder. Although I have been totally satisfied using my 70-200mm with the 2X TC, the added reach combined with great autofocus, sharpness and lighter weight make this lens my "go to" for birds.

Rated 5 out of 5 by from My long wait is over Ive been wanting this lens for a couple years but i kept not buying it because its so expensive. And being retired money is not easy to come by. Im 75 years old now so it was really a want instead of a need. So i just want to let others know that this lens is awesome and a definite keeper. Wish i could have bought it sooner. I have a Sony telephoto 70 to 200 f4. But found it just didn't have the reach i wanted a lot of the time. I read the reviews of others trying different brands and they didn't seem satisfied so thats why i got the Sony….its focus is amazing and I'm totally satisfied.

Rated 5 out of 5 by from Wonderful range and picture quality Got this for wildlife photos and it does not disappoint. Very happy with the image quality and how responsive the lens is.

Rated 5 out of 5 by from great lens love it only take it off to switch to a wide angle lens. produces sharp images and so far tracks moving objects with incredible accuracy. paired it with the 1.4 teleconverter and it is still super sharp and fast. in my opion it is well worth the price I paid

Rated 5 out of 5 by from My favorite lens I have owned and used the Sony 24mm, 24-105 and 70-200 lenses. I also have the 24-70 2.8. Despite other lenses being more compact, the Sony 100-400 GM is on my a7Riii all the time. I only switch when I want to photography something specific. Many people say the 70-200 is a good all around lens, but I now use the 100-400 instead, which has replaced the 70-200. I love the close focusing distance, fast focus and image quality from the 100-400GM. And yes, I use it mostly hand held, which is a testament to the overall handling of this lens.
