I think these are great, you should be happy with them! What lens were you using, looks like maybe a canon 100-400? I went to a hunt test to take photos and by the time I lugged my tripod, camera and 6.6 lb lens over 500 miles of bumpy terrain following everyone else on HORSEBACK...when I caught up with the group all the action was long over and no dogs left in sight and I was ready to collapse.
