CANON EF 70-300mm f/4-5.6 L IS USM — Optical Cross-Section & Ray Tracing

Home / Lenses / Canon / CANON EF 70-300mm f/4-5.6 L IS USMCANON EF 70-300mm f/4-5.6 L IS USMJP 2013-140404 A↗, Numerical Example 1 — Shigenobu Sugita
19 elements / 14 groups
72.20–290.00 mm design EFL
f/4.20–5.86 design aperture
2 UD elements
All-spherical
Focus MechanismCanon specifies 1.2 m minimum focus; JP2013140404A Numerical Example 1 publishes only infinity-focus zoom spacings, so this transcription models zoom at infinity and keeps close-focus spacing entries equal to infinity values.
