Mike, glad to see you're posting larger sizes. The focus on this does seem a bit soft, but after seeing your other post, I wonder maybe if you just cropped too tightly. both images suffer from being off keel. This one's not too bad but the reflections give it away. Did you use your tripod on this one?
Yes, Mike, our friend speaking before me, Rob seems to be right - tripod I am considering to purchase too myself but perhaps the lack of sharpness comes from my hands shaking with age= nature ...
And well, please work on the sharpness of your images because you do not have my excuse = age !!! LOL
LOVELY DUCKS !!!
