Hi all,
Was just wondering if anyone has tried the canon 400mm 5.6 with either a 1.4x or 2x TC on a crop body. I know it would be on the slow side and would be manual focus but I was wondering how IQ is and if the combo is even worth trying. Of course it would be used on a tripod in good light. Was trying to consider a cheaper option for shooting shorebird chicks next season. The 100-400 fell short for trying to photograph the chicks the other day.
