EF 100-400mm L-Series Telephoto Zoom
This Canon L-series lens covers a 100-400mm focal range with a variable f/4.5-5.6 maximum aperture. It mounts on Canon EF cameras, serving both 35mm full-frame and APS-C formats where it provides a 160-640mm equivalent reach. The optical design uses 17 elements in 14 groups, including fluorite and Super UD glass to control aberrations. It targets photographers needing extended reach for wildlife, sports or travel subjects.
Two-Mode Stabilisation and 1.8m Close Focus
Optical image stabilisation corrects camera shake by up to two stops, aiding handheld shooting at the long end. The minimum focus distance is 1.8m (5.9ft) with 0.2x maximum magnification, allowing frame-filling shots of larger nearby subjects. At 400mm the aperture stops down to f/32-40 for depth-of-field control. The lens cannot focus closer than 1.8m, limiting its use for small-detail macro work.
Ring USM, 77mm Filter Thread
A ring-type ultrasonic motor delivers fast, quiet autofocus with full-time manual override via the focus ring. The adjustable zoom ring lets users set zoom tension for smooth or rapid framing. The front barrel does not extend during focusing, helping maintain balance and sealing. A 77mm filter thread accepts standard circular polarisers or protective filters. The white finish reduces heat absorption during prolonged outdoor use.

Questions about this item
Will this EF 100-400mm f/4.5-5.6L IS USM work on my older Canon EOS body that only has an EF mount and no RF adapter?
Yes, the lens uses the Canon EF mount so it attaches directly to any EOS DSLR with an EF mount, full-frame or APS-C, without an adapter.
How can I verify the two-mode optical image stabilisation is active after mounting the lens?
Switch the stabiliser to Mode 1 or Mode 2 on the barrel; a subtle hum and steadier viewfinder image at 400 mm confirm it is working.
Does the box include a 77 mm protective filter or do I need to buy one separately?
The lens ships with front and rear caps and a hood; a 77 mm filter is not included and must be purchased separately.
