Is there a cheap alternative to the 18-55 kit lens that *interally* focuses?

No, with AF enabled. With CPL on I focus first, then rotate CPL gently because AF mechanism holding it.

This sounds dangerous. Seriously.


See the light.

No it doesnt. The cpl has 2 parts. The back part screws in to the lens, the front part rotates freely for you to adjust.

*Frowns* The last CPL I had certainly did *not* contain two parts.

Pics? Every CPL I've ever seen was designed to that the front element of the filter could be rotated to control the effects of polarization.

They don't have two *separate* parts, but they are indeed composed of two parts. The threads screw into the lens and the filter rotates freely, independent of the lens movement. Even the old polarizer filters I owned for my 35mm SLR lenses did that, and I believe they were linear (as opposed to circular) polarizers.

It's not 2 separate parts. The front that holds the glass can be turned independently of the part that screws into the lens. A CPL that didn't wouldn't be any use.

But when you rotate the filter, it changes the focus! Right?

Wrong. the rotating part of the CPL filter is the polarizer, not the screw mount.
