Sony SEL400F28GM 400mm F/2.8 Camera Lens: A Detailed Description

The Sony SEL400F28GM is a remarkable piece of optical engineering, designed for professional photographers and enthusiasts who demand nothing short of excellence. Here's a detailed breakdown:

1. G Master Series Excellence:

   • The SEL400F28GM belongs to Sony's prestigious G Master (GM) series. These lenses are renowned for their uncompromising image quality, exceptional build, and cutting-edge technology.

2. Super Telephoto Reach:

   • With a focal length of 400mm, this lens is a super telephoto powerhouse. It allows you to capture distant subjects with incredible clarity and detail.
   • Whether you're shooting wildlife, sports, or celestial events, the 400mm focal length provides that coveted "up close and personal" perspective.

3. Aperture: F/2.8:

   • The wide maximum aperture of f/2.8 is a game-changer. It enables exceptional low-light performance, beautiful bokeh (that dreamy background blur), and faster shutter speeds.
   • Photographers love this lens for its ability to isolate subjects and create stunning depth of field effects.

4. Optical Construction:

   • The SEL400F28GM features 17 lens elements in 13 groups.
   • Among these, there are three fluorite lenses, which contribute to outstanding resolution and reduced chromatic aberrations.
   • The 11-blade circular diaphragm ensures smooth and pleasing out-of-focus areas.

5. XD Linear Motors for Autofocus:

   • Sony has equipped this lens with newly developed XD (extreme dynamic) Linear Motors.
   • These motors drive autofocus with lightning speed, precision, and near-silent operation. Perfect for capturing fast-moving subjects.

6. Optical SteadyShot (OSS):

   • The lens incorporates Optical SteadyShot, Sony's image stabilization technology.
   • OSS compensates for camera shake, allowing you to shoot handheld at slower shutter speeds without compromising sharpness.

7. Nano AR Coating:

   • The front element features Sony's Nano AR Coating.
   • This advanced coating minimizes flare, ghosting, and unwanted reflections, ensuring crisp, contrast-rich images even in challenging lighting conditions.

8. Weather-Sealed Construction:

   • The SEL400F28GM is built to withstand the elements.
   • It's sealed against dust and moisture, making it suitable for outdoor adventures and unpredictable shooting environments.

9. Professional Features:

   • Full-time Direct Manual Focus (DMF) allows seamless manual adjustments even when autofocus is engaged.
   • The focus ring is smooth and precise, enabling fine-tuning.
   • The lens hood is robust and effectively shields the front element from stray light.

10. Compatibility:

    • This lens is part of Sony's E-mount system, compatible with full-frame mirrorless cameras like the α7 series and α9.
    • When paired with the α9, you can achieve an impressive continuous shooting speed of 20 fps at f/11 or larger apertures.

In summary, the SEL400F28GM is a masterpiece—a blend of optical prowess, cutting-edge technology, and rugged build. Whether you're capturing wildlife in the Serengeti or documenting a high-speed race, this lens delivers exceptional results.
