I have a Sony NEX 5n. I like it a lot. The quality of the digital imagery I can achieve with it finally motivated me to adapt to these automated type cameras, and furthermore, I am willing to try to take advantage of some of the auto focus benefits I previously shunned, especially to take advantage of the amazing video capabilities. Mainly I just use single focus mode and just lock the exposure and focus on static subjects, but I need better facility for moving objects or video. My question is what is the difference between continuous auto focus and object tracking. On my camera with a touch screen, I find that for video, it is convenient to touch the screen in object tracking so I can shift the focus point. With respect then to still shots of moving objects and also video, I don't have a reliable workable technique. I know that the contrast detection of my 5n isn't as fast as phase detection, but can somebody outline a good procedure for setting the camera for stills of moving subjects and perhaps a different approach to video of a moving subject(s)? Don't worry about conveying the most artistic aspects. I just mean with respect to settings, what should I be starting with?
