Yes, you rotate a ring next the front of the lens to focus.°O°Joe;22113314 said:So if I used a this lens and had to manual focus it on say, a Pirate on PotC, how quickly can it be done? I've never used this type of lens before... I didn't know if it was just a single ring on the outside that you turn until the subject appears focused??
The big problem is that the viewfinders in DSLRs really aren't manual-focus friendly. First off, the entry-level ones have pentamirrors rather than pentaprisms, so they're a little darker. But the big problem is that there's no split-image or microprism, which helps tremendously with manual focus. Some cameras allow you to change the viewfinder (I'm not sure that you can with the D40), you can buy such viewfinders from Katz Eye. The problem is that they will often confuse the camera's auto-exposure slightly. I may put one in anyone in my camera one of these days, they make such a big difference.
Manual-focusing on a dark ride will be tough, especially as you're going to be dealing with a very small DoF so perfect focus will be pretty important. I have done manual focus shots with my Zenitar fisheye on Big Thunder, but that's a completely different kettle of fish - huge depth of field, so you really don't need to focus it at all.
