Ooops !!
Yes you're right. It was from a thread discussing the Bigma and a Tamron.
Do you think the claim that they're hand held is right ?

i suspect they are rested against wire or pressed against the fence .i think some of the claims in these sights are a bit economical with the truth. a lens of this length would usually need a tripod or at the least a mono pod for stability |

Keith. | Could be. The usual reccomendation is that, for lenses without image stabilisation (or vibration reduction for us Nikon users), your shutter speed should at least match your focal length. So it should be possible to get sharp images with a handheld 500mm lens by using a shutter speed of 1/500th sec or faster. Do either the Bigma or the Tamron have image stabilisation? If so that would mean that you should be okay at 1/250th sec or possibly even a little bit slower.
The weight and balance of the lens will also have an impact but there are techniques for holding your equipment that can help improve stability and reduce camera shake. Or as Malcolmx says they may have braced against the wire or bars which would also help.

Dave P. | neither the Bigma or Tamron do have IS, but as Dave says it is possible to handhold long lenses (without IS) as long as light levels are good. I handhold my 400mm lens virtually all the time and have taken shots as slow as 1/100 sec with the my elbows firmly braced against my chest. Handholding a 500mm lens is obviously slightly trickier, but Graham (glsammy) does this fairly regularly as well. Your strike rate will be higher with a tripod or monopod, but there are occasions when handholding is more convenient.
for instance, this one was taken at 1/100, f5.6, with my Canon 400mm prime, handheld
