Message: <blockquote data-quote="RAH" data-source="post: 1632606" data-attributes="member: 5834">I should have mentioned in my last post that the reason I was trying the 120-600 lens on these cormorants was because I had not had good success with them before using my 70-300 plus EC-14, because it wasn't powerful enough and I was too far away. So I figured - GET MORE POWER. 600mm is 1200mm equivalvent - 24X! Well, nothing is simple at this type of magnification, and there is no substitute for getting closer. You'd think that with the luck of the draw, one or two of my hundreds of pics taken with the 120-600 would be really nice. No such luck. And as I said, the 70-300 plus EC-14 didn't yield good results earlier, so more power often isn't the answer either.</blockquote>
