Outstanding Flash for Canon SX 10 IS!
I recently upgraded from the Canon S5 IS to the SX 10 IS and bought this Sunpak not for the extra flash range, but simply to take that task from the camera, and quicken / improve the recycle time (and increase battery life). My primary use is for fill flash, and this is mostly outdoors.

The Sunpak is small, pocketable and does the job well! At it's size, I was amazed to find it had been designed to provide bounce flash as well. I've experimented with this indoors and now have a new benefit I was not counting on (or looking for).

I also love the fact that this flash sits nicely atop the SX 10IS (and G10) - having tried a competitor's flash previously, it almost looked as though the tail was wagging the dog. The smaller, shorter profile of this flash makes a perfect package, the balance and esthetics are excellent. I'm spareing technical details here, but will mention the E-TTL II interface has been just as claimed - it WORKS!

If you have an SX 10 IS (or it's big brother with HD Vid & RAW), a G9 or G10 ... or even a Powershot S5 IS, this flash will be worth every penny to you. I was skeptical on third-party E-TTL II compatability, this Sunpak has allayed those concerns. On top of all this, it fits nicely in a small pocket of your camera bag and looks great!

Perfect for Canon G Series
I've been shooting with a Canon G9 for about a year or so. Although it does have a built-in flash, it (like every other built-in flash) is a recipe for redeye.

Let's face it, straight on-camera flash will make your subject look horrible. You need to get the flash off the camera or at least bounce the light to soften the shadows. This little unit works great when it comes to bouncing light off a ceiling or wall.

One nice thing about the Canon G cameras is that they work great with Canon's e-TTL flashes. Unfortunately, most flashes are larger than the camera. It seems kind of silly to own a G series camera and use it with a flash meant for a 5D.

Sunpak to the rescue. The RD2000 is small and light enough to match nicely with the G cameras. It uses only 2 AA batteries which helps keep the size down. The controls are minimal and I really like the ability to adjust exposure on the flash itself by just pushing a button. Even the foot is well designed and folds back into the flash body to keep things compact.

It's not the most powerful flash, but it does have enough power to allow for bounce flash. For rooms with higher than normal ceilings, it may be necessary to raise the ISO on the camera to 200, but that's a small price to pay.

If there's one shortcoming it's the build quality. I know that I've praised its light weight, but I could have lived with another ounce or two of weight if Sunpak had made this unit with heavier plastic. This is not pro-level gear and needs to be treated gently.

I also think that it's a bit pricey, but considering the alternatives, it may be the only logical solution to shooting flash with a G.
