I suspect that I shall have to have far better weather than we are having at the moment to get the best out of my 1.4 converter but initial results look fairly promising.But shooting at half a stop in at 1/200 sec.are hardly going to shine with my 150-500 zoom at full ext.So Iwill have to let you know later how I get on ,sorry I cant be more constructive than this . consequently Iwill have to put my rating on hold Thanks for thr prompt service though ,best wishes BCS.
