Some fish eating birds along with the obligatory Mallard

Really enjoying this 50D, just wish I didn't have to give it back on Friday! Wish I had more time to take some pictures. Oh well. Here is what I came up with my hour lunch break. Considering the lens, I'm happy with the outcome. I just hope I can find one next year when I'm finally in the market.

One other comment, I noticed the lens is very loose fitting. I don't have this loose connection with my Rebel. Is that common, or is there possibly something wrong with the body?

nice set. I like the second to last one most.

You did real nice, all are very nice. I am cetainly no expert, but I have that same problem with one TC, it locks but rotates ever so slightly, the only lens I have that does that, It does make a difference quality wise when it is not in the right place. So somethiing is worn a has some problem, all my other lens don't move at all.
Very nice shots especially #1.

Very pretty shots! Love your cormorant and merganser.
