Model: Canon EF 300mm F/4 L IS USM Prime Lens Full Frame   S/N: 163486

This is a used lens with an older optical design.

  • Sample photos and description show the typical performance of this model, not a perfect, brand-new lens.
  • Fine pixel-level softness, some corner softness, light vignetting or minor color fringing can be normal for this lens type.
  • If you need “as new” or perfectly sharp performance at 100% zoom, this item may not be suitable for you.
  • We have checked that there are no defects that affect normal photography.

About focus / AF

  • AF has been tested on a camera and works correctly.
  • If focus feels wrong, it is often due to camera settings (AF mode, MF/AF switch, focus area, shutter speed, user settings, etc.).
  • Please send me a message before opening a return request.
  • I can help you check the settings step by step.

About corner sharpness

  • Like most lenses of this type, corners can be softer when shooting wide open (lowest f-number).
  • For sharper corners, please use around F5.6–F8 when possible.
  • This is normal optical behavior, not a defect of this copy.

Inspection standard

    Checked:
  • Haze, fungus, strong scratches, balsam separation
  • Oil on aperture blades
  • AF operation and aperture operation
  • Very small dust and light cleaning marks that do not affect normal shooting are not treated as defects.
  • The lens passed a functional test on a camera body before listing.
