Przytoczę cytat z forum na fredmiranda:Zamieszczone przez Vitez
"I was able to handhold the 300mm 2.8 at about 1/4s and get a super sharp shot. Last year when Blair was in town, he was able to handhold a wide angle shot for 20 seconds, and get a VERY sharp photo without blur. It all depends on how good YOU are at hand holding."
