Canon EF 600mm f/4 L IS III USM Lens

Valued for its use in sports and wildlife photography, the EF 600mm f/4L IS III USM is a super telephoto lens from Canon's L-series, recognized for its innovative, lightweight construction, rapid and user-friendly operation, and exceptional speed performance. The incorporation of fluorite, Super UD, and aspherical elements effectively minimizes both chromatic and spherical aberrations, resulting in sharp, clear images with precise color reproduction and fidelity. Additionally, the Super Spectra and Air Sphere Coatings enhance color accuracy and mitigate flare and ghosting, particularly in challenging lighting situations such as backlighting.

Beyond its optical advantages, the 600mm f/4 lens is distinguished by its state-of-the-art five-stop effective Image Stabilizer system, which features three distinct stabilization modes tailored for various shooting scenarios. Enhancing its usability is a sophisticated ring-type Ultrasonic Motor (USM) that ensures rapid, silent, and precise autofocus performance, along with the option for full-time manual focus override. A customizable electronic focusing ring further enhances manual focus accuracy by offering three sensitivity levels suitable for different situations. Moreover, this lens is designed to be weather-sealed, making it suitable for challenging environmental conditions, and it includes a removable rotating tripod collar, facilitating use with a tripod or monopod.

• Super telephoto prime is designed for full-frame Canon EF-mount DSLRs, however can also be used with APS-C models where it provides a 960mm equivalent focal length.
  
  
• Bright f/4 maximum aperture affords control over depth of field for working with selective focus techniques.
  
  
• Super UD and fluorite elements are used to greatly reduce color fringing and chromatic aberrations in order to achieve greater clarity and color accuracy.
  
  
• Aspherical elements help to limit spherical aberrations and distortion for greater sharpness and accurate rendering.
  
  
• Super Spectra and Air Sphere Coatings have been applied to individual elements to control lens flare and ghosting for greater contrast and color fidelity when working in strong lighting conditions.
  
  
• An Optical Image Stabilizer helps to minimize the appearance of camera shake by up to five shutter speed stops to better enable working in low-light conditions and with slower shutter speeds. Three distinct IS modes are available: standard single-shot mode, a panning-optimized mode, and a mode that only activates the Image Stabilizer during the exposure.
  
  
• A ring-type Ultrasonic Motor (USM), along with optimized focusing algorithms and a high-speed CPU, is employed to deliver fast, precise, and quiet autofocus performance as well as full-time manual focus override.
  
  
• Customizable electronic focusing ring provides three sensitivity levels for how quickly and precisely the lens can manually focus.
  
  
• Focus Preset function is available to quickly recall a programmed focusing position.
  
  
• Rounded nine-blade diaphragm contributes to a pleasing out of focus quality that benefits the use of shallow depth of field and selective focus techniques.
  
  
• As a member of the esteemed L-series, this lens is sealed against dust and moisture for working in inclement environmental conditions and also features a fluorine coating on the front and rear elements to guard against water spots, smudges, or oil residue.
  
  
• Removable rotating tripod collar is included and benefits working with the lens atop a tripod or monopod.
  
  
• Compatible with optional EF 1.4X and EF 2X teleconverters.
