I live near the Chesapeake Bay. I like to take pictures of ships. These ships are far away, near the horizon. I have been using a Canon T6S. When I use a Sigma 18-250mm Lens at F8 and I magnify the picture in Picasa, the result is terrible. My question is, if I decrease the lens opening by increasing the F stop will the image be sharper? Thanks for your help.
Are you sure you're not experiencing "atmospheric distortion" from far away distance cutting through vaporized water?
