It replaced a Canon EFS IS lens 17-85mm that I bashed in Barcelona and that finally died a couple of weeks ago.

The Sigma has a much wider range of focal lengths and I’m sure I won’t miss that 1mm at the wide angle. It also means that for the most part I can avoid carrying my much bulkier Canon 75-300mm lens.

This male mute swan was shot on the river Alde on a recent visit to Aldeburgh in Suffolk. The image was snapped at full zoom with the Sigma lens (i.e. 200mm), 1/500s shutter speed, aperture f 8.0, and “film speed” ISO 100, the image fairly tightly cropped around the swan.

What made the Sigma lens particularly attractive aside from its compact size is that it was half list price on Amazon UK and was a less expensive investment than paying to have the Canon lens it replaced fixed.
