Replacement Foot for Sony 400–800mm

 

🦅 Hejnar Photo Replacement Foot for Sony 400–800mm: Stability Meets Precision

Sony’s FE 400–800mm f/6.3–8 G OSS lens is a super-telephoto marvel, built for wildlife, sports, and outdoor shooters who demand reach and clarity. But with great length comes great leverage—and that’s where the Hejnar Photo Arca-Type Replacement Foot steps in.

🔧 Why Replace the Stock Foot?

The factory foot on Sony’s 400–800mm lens is functional, but not optimized for serious tripod or monopod use. The Hejnar replacement foot offers:

  • Arca-Swiss compatibility for seamless integration with ball heads, gimbals, and clamps.
  • Lower profile and improved balance for better center-of-gravity alignment.
  • Captive 1/4-20 screw mount for secure attachment.
  • QD (Quick Detach) socket option for sling-style strap mounting.

Whether you're tracking a bald eagle or shooting motorsports from the sidelines, this foot delivers the kind of stability and modularity that professionals expect.

📐 Precision Engineering

Made in the USA from 6061-T6 aluminum, the Hejnar foot is:

  • CNC-machined for exact tolerances.
  • Black hard coat anodized for durability and corrosion resistance.
  • Lightweight yet rigid, minimizing vibration and flex during long exposures or fast action bursts.

It’s compatible with top-tier support systems including RRS, Markins, Wimberley, Kirk, Acratech, Photo Clam, Foba, Jobu Designs, and Vanguard ABH Series.

🧰 Ideal Use Cases

  • Wildlife photography: Long lens setups on gimbals or tripods.
  • Sports and action: Quick repositioning with Arca clamps.
  • Field work: Sling-ready with QD socket for mobile setups.
  • Studio and macro: Precision alignment with nodal rails or macro stages.

📦 What’s Included

  • One replacement foot for Sony FE 400–800mm lens
  • Captive mounting screw
  • Hex key for installation

🚚 Shipping & Availability

Hejnar Photo offers free USPS First Class shipping with tracking. For time-sensitive orders, expedited options like FedEx, UPS, or Express Mail are available at checkout.

If you’re serious about maximizing the performance of your Sony 400–800mm lens, upgrading to a Hejnar foot is a no-brainer. It’s not just a replacement—it’s a precision upgrade.
