[QUOTE="cwgrizz, post: 572877, member: 27017"] I'm going to jump in a give you some ideas. They may or may not be 100% correct, but usually after putting my stuff up here, there will plenty of others with good info jump in to correct me and you will end up with the good stuff. Ha! As you may or may not have seen in your research there are three things that can effect how much is in focus in your shot. Aperture: The more it is closed down (High f stop #) the greater amount of the scene will be in focus. This is if the lens focal length and focus distance stays the same. Focus Distance: The farther away the focus distance the greater amount of the scene will be in focus. This is if the lens focal length and the f stop are the same. Focal Length: The wider the focal length, the greater amount of the scene will be in focus with the focus distance and the f stop the same. Here is where you will have to do your own testing. The wider end of you lens (24mm) will give you the most in focus area, but you may have to move closer to your subject to have it the size you want in the photo. You may have to move your subject (if possible) closer to your background. I think I would set a chair or something where I wanted the main subject to be and play with the wide end of you lens. Focusing at 10m (distance to subject) will give you approx. a focus range of 3m - ??? with an aperture of f8. Increase the f stop and you should get a longer distance in focus. Ha! One cheat sheet that I like on DOF can be found [URL="http://www.techradar.com/us/how-to/photography-video-capture/cameras/3-ways-to-affect-depth-of-field-free-cheat-sheet-1320935"]here[/URL] Another option may be to look at some of the DOF calculators that can be found online or some of the APPs for smart phones. No matter how you look at it there is some compromise. You have to decided at times which is more important for your photo? The subject in the foreground or the horizon. I would think that it would be the subject in the foreground and that would be the place to focus on. Oh and welcome to the forum.
