Canon EF-S 55-250mm f/4-5.6 IS STM
£270/$300
Light, but not especially small
Like the Nikon 55200mm and Pentax 55-300mm lenses on test, this Canon telephoto is designed for SLRs with APS-C
format image sensors. It’s physically longer than both competitors, at least when not in use, because it doesn’t share a retractable design. On the plus side, it’s immediately ready for shooting without having to first extend the barrel. It’s also fairly light at 375g, with a plastic mounting plate.
Compared with the previous edition of this Canon lens, this model has a stepping motor (STM) autofocus system, which is quicker and quieter. Handling is also improved, as the focus ring no longer rotates during autofocus and enables manual override, via an electronic coupling. Image stabilisation is rated at 3.5 stops.
Performance
Image quality is good overall. Sharpness isn’t great, but at least it’s quite consistent through the entire zoom range, and doesn’t drop off much at the widest available apertures. Overall, it’s a simple yet effective lens with solid performance.
