canon ef 24 2.8 is usm
I recently purchased an EF 24mm f/2.8 IS USM from eBay and I'm not convinced the image stabilization is working. Obviously, the switch is set to "IS". With my L series glass, there's usually a little click or whir and can see the glass move through the viewfinder. With this 24mm lens there is no sound or movement that I can discern.
Has full-time manual focus. Canon EF 24-70mm F/2.8L II USM. Canon EF 50mm F/1.8 STM. With full-time manual focus, you can move the focus ring whilst it is in AF (autofocus) mode. This means that you can make manual adjustments once the AF has finished, without changing to manual mode.
