Excerpt: You may be thinking that the Sigma 800mm f/5.6 EX DG HSM weighs a ton but at less than 5kg, it's actually quite reasonable. That may still sound ridiculous, but this lens is not designed to be handheld. It's not only the weight but the focal length that makes this lens cumbersome. At 800mm you ideally need to be shooting at least 1/800sec, although using a monopod or tripod means you can get away with a few extra stops.
