Canon XSi/450D

Polarizer filter & kit lens

Written by Digicamhelp Editor

Using a polarizing filter on the Canon XSi/450D kit lens can be a pain. Here’s how to get it to work correctly on lenses with rotating front elements.

Natural history photographer and Digicamhelp Contributing Writer Deb Tappan suggests using the type, or barrel ring grooves, as an indicator of roughly where the focus is set. Hold the lens so it doesn’t shift, and make your polarizer adjustment.

According to Deb, “since the polarizer doesn’t have to be right-on to be effective so, you could focus, get your polarizer lined up best you can, then double-check your focus and shoot. Not the zippiest process but effective.”

I’ve successfully used a polarizing filter on my XSi. Adjusting it takes some getting used to, but it can be done.

Deb also points out that there are other entry-level, economically priced lenses whose front elements don’t rotate. For those who use a polarizer quite frequently, they may want to consider a lens with a non-rotating front element.

Both the kit and EF-S 55-250mm IS lenses take 58mm filters.
