Grip the right side of the body with your right hand, index finger on the shutter. Cradle the lens with your left palm, with thumb and index (or third finger*) on either side of the focus ring. This is a proven grip that will allow you to tweak the focus or the filters and operate the zoom when needed. Also, by supporting the lens, you will cut down on camera shake. Shake can be greater when you let the body support the lens.
* I know many who prefer to use their third finger here (with the index free to adjust a polarizer), but if you are new to the camera, be sure this doesn’t leave your index finger waggling in front of the lens.
