[QUOTE="WayneF, post: 542037, member: 12496"] No, the aperture does not affect focus. In fact, the DSLR lens is wide open at maximum aperture for the viewfinder, and for focusing, and for all of the time until the shutter button is actually fully pressed. Everything is brighter that way, viewfinder, and easier focusing. Then, only at shutter time, the lens actually stops down to your selected f/stop value for the exposure, and then it opens to maximum again. As you rotate your aperture wheel for different f/stops, you are just changing this wheel, not the lens... not until next time you press the shutter button, when then it stops down to the selected aperture. You can watch into the front of the lens to see this as you click the shutter (a slower shutter speed will help to see it). It is very normal, just the way it works. [/QUOTE]
