Sony FE 400mm f/4.5 GM OSS Lens | Sony E

The Sony FE 400mm f/4.5 GM OSS Lens delivers exceptional telephoto capabilities while maintaining a remarkably compact and lightweight design. This optical instrument combines the prestigious G Master optical engineering with portability that sets it apart among 400mm prime lenses. Featuring rapid autofocus performance, sophisticated built-in image stabilization technology, and robust weather sealing, this lens is engineered for versatile handheld photography across diverse environments, whether capturing dynamic sports action on the sidelines or documenting wildlife in remote natural settings.

Optimized for Handheld Use

This 400mm f/4.5 lens overcomes the typical portability challenges of super-telephoto equipment, making it practical to carry for extended handheld shooting sessions while maintaining the focal length you require across diverse shooting scenarios. The f/4.5 maximum aperture enables a more compact and lightweight construction while preserving adequate light collection capabilities, particularly when combined with optical image stabilization technology. By incorporating a single front element design, the lens achieves an optimized weight distribution with its center of gravity positioned closer to the camera body, resulting in superior balance for sustained handheld operation. Measuring just 9.5 inches in length and tipping the scales at 2.2 pounds, this lens exhibits proportions more reminiscent of a standard 70-200mm f/2.8 zoom than a conventional super-telephoto prime lens. In direct comparison to the FE 400mm f/2.8 model, this f/4.5 alternative delivers a weight reduction of 4.2 pounds and a length reduction of 4.6 inches.

High-Speed AF, Powerful OSS

Engineered for rapid performance, accuracy, and dependable operation, the autofocus and image stabilization mechanisms render this lens ideal for photographing athletic events and wildlife photography without requiring a tripod. A pair of XD (extreme dynamic) linear motors deliver swift and reactive autofocus capabilities that operate with minimal noise and exceptional smoothness. The autofocus mechanism supports continuous shooting in both still photography and video formats at frame rates reaching 120 fps.

Manual focus adjustment remains accessible at all times, while an internal focusing mechanism preserves the lens's physical dimensions and facilitates quicker autofocus response. A focus range restriction feature and four dedicated focus hold controls grant enhanced precision over autofocus behavior, helping you capture every critical moment. An intelligent Optical SteadyShot stabilization technology guarantees crisp, clear images during handheld operation. Three distinct stabilization options are provided: conventional stabilization (Mode 1), horizontal tracking for panning movements (Mode 2), and dynamic stabilization for moving subjects (Mode 3).

G Master Optical Performance

Sony's G Master designation is reserved exclusively for lenses that demonstrate exceptional sharpness, refined bokeh characteristics, rapid autofocus performance, and superior optical quality overall. This 400mm f/4.5 model combines this optical excellence into an unusually compact telephoto prime lens.

• Super ED and ED glass elements effectively minimize chromatic aberration while delivering outstanding edge-to-edge sharpness, even when shooting at the widest aperture, providing enhanced flexibility during composition and post-processing work.
  
  
• Nano AR Coating II technology effectively reduces lens flare, resulting in enhanced contrast and vibrant color reproduction across diverse lighting environments.
  
  
• The rounded 11-blade aperture mechanism produces exceptionally smooth bokeh with gradual focus transition, enabling precise subject isolation and definition.
  
  

Professional Operability and Design

To enhance portability even further, the included tripod foot can be conveniently detached to create a more compact form factor that works exceptionally well for handheld operation. The Customizable Function Ring offers the flexibility to be configured for managing an extensive range of camera and exposure parameters. An ergonomic control arrangement positions all regularly accessed buttons and switches within convenient reach on the lens barrel, enabling you to make adjustments while maintaining focus on the viewfinder. The dust- and moisture-resistant construction incorporates rubber gaskets along every seam and a protective rubber ring around the lens mount, making it suitable for challenging weather environments. The front lens element features a fluorine coating that resists water, oil, and various contaminants while simplifying the cleaning process. A 95mm front filter thread allows for straightforward attachment of threaded filters to expand your creative possibilities. The hybrid construction combines both metallic and polymer materials to achieve an optimal balance between robustness and lightweight design.

Teleconverter Compatibility

The Sony FE 1.4x and 2.0x teleconverters, which are sold separately, work seamlessly with the FE 400mm f/4.5 GM OSS lens. These accessories maintain complete autofocus and auto-exposure functionality when attached. The 1.4x teleconverter delivers an effective focal length of 560mm with an aperture of f/6.3, while the 2.0x teleconverter produces an effective focal length of 800mm with an aperture of f/8.
