Sony FE 400-800mm f/6.3-8 G OSS Overview

Redefining the Sony G Series
The farthest reaching Sony E-mount lens yet, the FE 400-800mm f/6.3-8 G OSS Lens from Sony is a super-telephoto powerhouse lens that's primed to be the dominant choice for capturing wildlife, nature, and sports. With this addition to the G Series, Sony continues to blur the lines between G and GM lenses, offering its users exceptional quality at a reduced cost. This lens features internal zoom for improved functionality as well as dual linear motors for smooth, quick AF performance. Optical SteadyShot stabilization includes three distinct modes, along with a focus limiter and three focus hold buttons for advanced control. For increased lens stability and sharper imagery, a fixed, rotating tripod foot is included on the lens.
Unprecedented Range
Not only is this the first Alpha zoom to reach 800mm, but its compatibility with 1.4x and 2x teleconverters extends the maximum focal length to 1120mm and 1600mm respectively, making this an elite choice for birding and wildlife as you'll be able to keep a safe distance from your subjects. Complementing its impressive reach is a zoom ring that offers smooth, precise rotation that is made to help prevent accidental focal length changes.
Prioritizing Functionality & Usability
Poised to outshine Sony's FE 200-600mm f/5.6-6.3 G OSS, this super-telephoto provides longer range and better overall lens performance while weighing just slightly more at 5.45 lb.

Featuring a short rotational throw, this lens allows you to make swift focal adjustments while capturing.

This zoom accepts screw-in filters on the front lens element, expanding your ability to create in various lighting conditions.

Multiple function switches are built into the lens barrel that allow you to make rapid settings adjustments, including a switch for AF/MF, OSS, and focus limiting.

Cutting-Edge Optical Design
Six ED lens elements significantly reduce flare and ghosting in backlit conditions and help control chromatic aberration in images.

An 11-blade circular diaphragm produces smooth and rich bokeh, ensuring effective subject isolation and blurred background when capturing with a narrow depth of field.

A complex optical configuration of 27 elements in 19 groups allows the lens to reproduce fine details and create high-contrast images.

Built to Last
  • Equipped with a dust- and moisture-resistant design, the FE 400-800mm f/6.3-8 G OSS maximizes reliability in the field, regardless of inclement weather conditions.
  • The front lens element features a fluorine coating that repels water and oil. This coating also makes the lens glass easier to clean.
  • A robust lens hood with a lock button adds significant protection and features a filter opening for quick and convenient filter adjustment.
High-Level Stabilization & Control
A 400-800mm zoom range demands exceptional lens stability, which is provided by Sony's Optical SteadyShot image-stabilization system. OSS utilizes a gimbal mechanism and an algorithm to effectively counteract camera shake by shifting the entire lens unit and sensor. When using a tripod, the lens's fixed mount foot can be easily rotated for horizontal or vertical capturing. Located around the lens barrel at 90° increments are three focus hold buttons, allowing maximum access in any orientation. These buttons can also be assigned to your preferred functions for making specific settings changes more quickly.

Sony FE 400-800mm f/6.3-8 G OSS Reviews

Needed more focal length

By Dennis

I am 78 years old. I love to photograph birds. My passion is to obtain the best possible photo of every bird on my life list. I suffered a stroke three years ago that paralyzed my right side. Cameras are designed to be held with the left hand and operated with the right hand. I have regained use of my right hand enough to again enjoy using my cameras. However, it’s not as easy for me to handle a heavy lens as it was before the stroke. I use this lens with a Sony A1M2 camera, and the combination weighs 8 pounds. I can handhold it for a short time, but I prefer to use it on a sturdy tripod with a gimbal head. Before the stroke, my “Go-to” Camera and lens combination was the Sony A1 camera and the Sony FE 200-600mm Lens. I didn’t give any thought then to the weight. Since the stroke, camera weight has become more of an issue. My most enjoyable combination is the Sony FE 300mm f/2.8 lens with an FE 1.4X teleconverter and the Sony A1M2 camera. It weighs just over 6 pounds and is a joy to use handheld. To get more focal length, I’ve tried several different combinations. I finally decided to buy a longer lens. I believe I made the right choice. Like the FE 200-600mm Lens, the zoom function of the FE 400-800mm lens is internal. The lens is the same length from 400mm to 800mm and you only need to turn the zoom ring about 1⁄4 turn. Focus is quick and accurate. It produces sharp images at max aperture provided there is adequate light. However, the “bird eye” autofocus does not ‘seem to be as reliable as with a “faster” lens. It is also more affected by heat distortion than a shorter lens. I find that working earlier in the morning or on breezy or cloudy days makes heat distortion less of an issue. At the recommendation of a friend and one of the reviews on B&H, I purchased the Leofoto, SF-04 lens foot. It has built-in Arca type dovetail mounts and several 1⁄4 - 20 and 3/8 - 16 tapped holes for attaching a monopod or a shoulder strap. Being a retired engineer, I was impressed with the quality of this replacement lens foot. Thanks to B&H for asking me to submit this review. I wouldn’t consider making my camera and lens purchases anywhere else.

Phenomenal Quality

I purchased this lens with intentions to photograph the moon and sun (with filter of course) and it did not disappoint! Images are very clear and the aperture is large enough to capture wildlife too.
