My short video demonstrating the continuous auto focus (cAF) during video with the Canon T4i and 40mm f/2.8 STM lens.  The pairing of the 40mm and the T4i is pretty sweet – the STM of the lens -stepping motors – provides quick and smooth auto focus and keeps your subject in focus. . . as long as your subject doesn’t move to fast.

How does it compare to the D3200?  comparing the continuous auto focus feature – With the Canon 40mm STM and I expect with the 18-135 STM it beats the nikon D3200 but with the other standard lenses the two are comparable.  If you are serious about video you need to learn how to manual focus.  If you are a parent of a kid playing sports. . . the more I use the T4i the less sure I am that you can rely on the AF to reliably and quickly focus on moving subjects during video.  You are probably still better off buying a camcorder.  But in the still photography world I am quite impressed with the T4i and will have samples of high ISO images up soon.  And as a video machine it is very good, just don’t expect the continuous auto focus to grab objects moving faster than a slow walk.

 Menzie's Penstemon or as the nerds say - Penstemon davidsonii ;) Found these little purple flowers on the way down from Paradise in Mt Rainier National Park and thought they made a nice foreground to the beautiful and still snowcapped peak in the distance.
