It is what it is... a simple, no-brainer flash. No serious settings to adjust, no serious factors to consider, a straight forward way to add more light into your pictures. If you want, you can make a few manual flash adjustments on the camera itself. Great bang for the buck.

I really like using it on my G10.

I purchased this flash for my new (and awesome!) Canon 5D Mark II. Most of the time, the Mark II can handle indoor and low lighting conditions without any issue; it's quite usable up to 3200 ISO. Still, even in RAW mode it can't handle all lighting conditions as it doesn't have an onboard flash. I like using flash for fill lighting especially for shooting flowers and insects. That's where the 270ex comes in as a carry around flash. The most surprising thing was how small and light it is; it really does fit in a shirt pocket. It powers up and is ready much faster than I expected considering it just takes 2 batteries. Considering the low profile, the forward angle of the build helps to eliminate lens shadows on long lenses. Still, it isn't without some faults; it isn't the build quality of a 580ex or 430ex. It also isn't the widest coverage I've seen on a flash with just 28 & 50mm settings. Still it's pretty great considering that it isn't supposed to be a replacement for a 580ex II.

Pros
*Light & small, fits in a shirt pocket
*Forward tilt angle doesn't cause lens shadow on a 24-105IS when fully extended
*Usable bounce angles
*Takes just 2 standard AA batteries
*Fast flash recharge
*Quite operation; way better than my 430ex Speedlite
*Good color temperature, not too blue
*Simple foot lock switch
*Easy operation with both the 5dII and 9G

Cons
*Less impressive build that more expensive Canon Speedlites
*So-so flash coverage when lens is 24mm or wider

I bought this because of it its small size and ease of use. I needed an external flash for indoor photography for reducing red eye and deer-caught-in-headlight effect. This flash is more than enough for my needs. Used it with Canon T1i. AF assist worked fine. The range is slightly better than the built-in flash in terms of telephoto and wide angle range but the evenness of lighting is pretty good compared to built-in flash. Excellent for indoor bounce flash photography. After getting this flash I have stopped using built-in flash for indoor photos. It needs only two AA batteries vs. 4 in bigger flashes. The bounce flash worked perfectly even in rooms with high vaulted ceiling. The colors are awesome vs. washed out colors with built-in flash. The faces don't look shiny anymore and no sharp shadows in the background. This flash is the way to go for indoor bounce flash. This flash can not tilt sideways so it can not be used for bounce flash for vertical photos.

I needed to get more flash than was produced by the stock flash on my Canon EOS Rebel. I did not want a large, heavy (4 or more batteries), mounted on the camera.
This unit solved the problem! It only uses 2-AA batteries and makes a big flash for a smaller unit. I'm a realtor and it fills the room for color rich pictures.
I love the bounce feature and find I'm using it whenever I have a white ceiling in a room. I'm not a photo artist but this Speedlite in combination with my 10 to 20 wide angle lense has helped me to produce wonderful listing photos. I love the compliments from the other agents in my office!

I bought this flash to go on a G10. It seemed the perfect one for a p&s, s\compact and easy to carry like the G10. Highly recommended as a higher power flash than the built in one.
-M. Miner (270EX Canon Flash user review from Amazon.com)

I'm a real novice, but I was easily able to figure out how to use this flash - and they do, of course, include instructions that I skimmed over. This is the only one I've ever used, so I'm not able to compare it to any others. I do like that I can change it's position to bounce off the ceiling, instead of a straight on flash.
