1. Overview:

   • Designed with precision and finesse, this lens caters to the discerning needs of sports and wildlife photographers.
   • It's not just a lens; it's a versatile optical tool that combines performance, reach, and flexibility.

2. Focal Length & Aperture:

   • The Canon EF 200-400mm f/4L IS USM Extender 1.4x Lens offers a focal length range of 200-400mm.
   • Without the built-in extender, it's a constant f/4 aperture lens. But here's where the magic happens: flip the switch, and the extender kicks in, extending the range to 280-560mm at f/5.6. That's like having two lenses in one!

3. Optical Construction:

   • Inside its robust barrel reside 25 elements arranged in 20 groups (including one rear filter) when the extender is off.
   • Engage the extender, and the lens transforms, revealing 33 elements in 24 groups (again, with that trusty rear filter).
   • These glass elements work harmoniously to minimize aberrations, enhance sharpness, and deliver stunning image quality.

4. Angle of View:

   • With the extender off, you get a diagonal angle of view ranging from 12° to 6°10'.
   • Activate the extender, and the view narrows to 8°50' to 4°25'. Perfect for capturing distant subjects with breathtaking detail.

5. Focus System:

   • The inner focusing system ensures smooth and precise autofocus.
   • Whether you're tracking a sprinting cheetah or a soaring eagle, this lens keeps up.

6. Closest Focusing Distance:

   • Get up close and personal! The minimum focusing distance is 6.6 feet (2 meters).
   • Macro enthusiasts, rejoice—you can capture intricate details even at this telephoto range.

7. Image Stabilization (IS):

   • The lens features Canon's renowned IS technology.
   • It allows you to shoot handheld at shutter speeds up to four stops slower than usual without introducing camera shake. Ideal for low-light conditions or when you're on the move.

8. Filter Size:

   • The Canon EF 200-400mm f/4L IS USM Extender 1.4x Lens uses a 52mm drop-in filter system.
