    Yes. The focus ring does move freely. If you want to lock it down, you need to use tape of some sort to build up the thikness of the focus ring. I leave mine open since I use the lens for pictures other than panoramas.

    R1 comes with various ring types - using the new Canon 8 -15 fisheye which ring clamp are you using ? Does new canon fisheye fit the Sigma 8mm Fisheye ring ?

    I do not think so, cause the canon lens has two outstanding knobs on the lens plus each ring is specially made for a type of lens. Fixing to parts of it's body wheere it may be fixed to which is not moving or causing damage.

    As often mentioned, Nick will make one as soon as he has the lens in his hands.

    switching from auto focus to manual will mean having to loosen then tightening the rings. it's kinda cumbersome or am i doing it wrong?
