Canon EF 400mm f/2.8L IS USM - Canon EF Mount

The Canon EF 400mm f/2.8L IS USM is a staple of professional sports and press photography. It combines a fast f/2.8 aperture with effective first-generation optical stabilisation, allowing for high shutter speeds in low light. The lens features a magnesium alloy barrel and a weather-sealed construction, though it is significantly heavier than later Mark II and III iterations. On the used market, these lenses often show external paint wear on the barrel and tripod foot. SDS checks the autofocus limiters and preset functions for full operation. It is important to ensure the Image Stabiliser engages and disengages quietly. We also inspect the drop-in filter holder for damage and check the front element for any marks that could affect contrast, as this model uses large, expensive protective glass.
