For some applications, such as bird, wildlife and sports photography, a long lens is a must. Most ranges include economical choices up to 300mm, but really something longer is often needed. Increasing the focal length to 400mm results in much higher cost and larger, heavier lenses. However, Sigma has now introduced this 100-400mm Contemporary zoom lens that is reasonably priced, fairly compact for a 400mm and promises a high level of performance. Coupled with the Canon EOS 5DS R for this review, let’s investigate further.
Handling and Features
This is not the first time that compact versions of longer lenses have appeared, as 400mm f/5.6 lenses have been offered in past that have also meant lower cost, smaller and lighter optics. This can be no bad thing as some lenses can be very heavy indeed and wearisome to carry. Having said that, the new Sigma lens still weighs in at a hefty 1160g. Perhaps surprisingly, there is no tripod mount on the lens and although this presented no problems on test, it is about as far as might be sensible to go relying on the camera’s own tripod mount.
