Re: Canon EF 50mm f/1.4 Micro USM Finally Coming? [CR1]
The same would be true for the 50 STM, because the front element can stick out quite a bit when you set focus. Now if I would store it like that, I can imagine that it is easily possible to damage the focusing motor.
But "stupid Canon" developed a simple and smart solution; everytime I shut off the camera, it will also quickly move the lens tube back inside, so that it doesn't stick out and there won't be any issues at all when storing it in your bag. I believe this should also be possible with nanoUSM. So I wouldn't worry about that in future iterations of the 50 1.4 lens.
So if it will have internal focusing like the 35IS, then good, if not, it won't be that dramatic at all. Agree?
