Hello, I'm a new Canon (and DSLR) user. I've got a T3i with the kit 18-55mm EF-S IS Lens. I've had it for several months now, and really enjoying the power and flexibility of the camera as I'm learning how to use it, but I'm experiencing a problem with trying to manual focus during video. The focusing ring on the lens wiggles just a little - it's very small, but just that little bit causes video to jump and jiggle when using manual focus at even the slightest finger shake. I use my camera mostly for video, and at least 50% of my video takes require manual focus, so this is a big problem for me.
Can I fix this myself or is this a problem that requires a professional fix-job? Or is it just a deficiency in the cheap lens? I'm on a tight budget, and while I'm hoping to pick up a 50mm, the wiggle in my 18-55mm makes video with manual focus useless unless the greatest care (and luck) happen to pull off a decent shot.

"Can I fix this myself or is this a problem that requires a professional fix-job?"
You can not likely fix it yourself and it is not a good candidate for professional repair.
"...just a deficiency in the cheap lens?"
It is a "cheap" lens but they seem to work fairly well and have for many years for many people. It may be the most widely sold lens in the world until the release of the STM version. The STM version is much better and is way better than yours for video. I would go that route in favor of repairing yours. In fact I would buy it even if yours was not broken.

It sounds like your lens could be broken in some way. It is likely that you can buy a used one for less than the cost of a repair.
I recommend replacing with a new Canon lens. The updated EF-S 18-55mm f/3.5-5.6 IS STM lens is a good choice.

Try this:
Hopefully this solves your problems, and you never have to worry about it again! With my personal lenses that are not USM or STM, I always store and transport them with the AF/MF switch in the MF position. This disengages the focusing motor and prevents any accidental damage to the auto focusing motor.
