Re: Manual focus?

I haven't seen that lens in person but I assumed that rear lens
element would be bigger than it actually is, it actually looks to be
about the same size as the canon 50mm f/1.4.

The rear lens element diameter is 38 mm.

The rear lens element diameter is 37.4 mm on the 50mm f/1.4.

I have converted a few canon lenses to SA mount and those with
electronic manual focus lose the ability to manual focus with the SD9
and SD10, although auto-focus works well.
Does the electronic manual focus on that lens work with the SD14?

I dont know. Some people say me the same. But Canon 50 1.2 have not
electronic manual focus. When i move focus ring i lens inside moving.
It work without camera. It is real manual focusing lens. Electronic
manual focus have Canon 85 1.2 lens.

Thank you for that info on the 50mm f/1.2L and you are correct about the 85mm f/1.2L being an electronic manual focus lens, along with most of the "big whites". If the focus elements move when it isn't mounted on the camera it can't be an electronic manual focus lens. It's not the first time the specs listed on the B&H website are incorrect.
