Had most of the morning to play whilst attending the Starmus Festival in Tenerife.  Took the faithful Canon 5D MkII down to the beach for some HD video work using the Canon 100-400mm telephoto lens and a 1.4x teleconverter – hand-held.  I think the results from this DSLR are quite impressive (with a tripod and fluid head it would have been even better of course).
