• Two focus presets can be stored for immediate recall to a specified focus distance.
• Focus range limiter improves responsiveness by constraining the usable focusing range.
• Benefitting handheld and monopod-based shooting, Optical Image Stabilization compensates for 4 stops of camera shake for sharper imagery. Due to the long focal length, in-body image stabilization, or Coordinated IS, from EOS R-series bodies is not supported with with this lens.
