Being someone who knows how a bounce flash can add to a picture i decided to purchase the 270EX to use on my newly aquired Canon G12. I was looking for a small compact fairly powerful flash that could offer bounce and also take a Stofen diffuser. The flash is compact and easy to store in a pocket. It comes with a pouch and requires 2 AA batteries to function, which i found last around 60 flashes. I now use Lithium AA batteries and so far have got 140 flash shots out of a pair! The bounce head also zooms and you can adjust the bounce at several angles. The flash can be adjusted in small steps of 1/3rd so you have good control on power output. Mounted on my G12 the flash sits and balances very well. It makes a great travel kit with the G12 which is perfect when you want to travel light. Using the bounce function gets more realistic colours then using the on board camera flash and you can avoid the harsh shadows direct flash lighting can cause. Overall a good investment especially that i got it for a good price off £98 on Amazon Nov 2010.
