I do mostly outdoor photography but I am thinking about getting a 270 EX II speedlight. I just wanted something small and compact to throw in the bag in case I needed a little more flash than the pop-up offers. Does anybody have a 270 and what do they think about it.....Thanks !
I've used one, but found it not really powerful enough. The pop-up flash of many EOS cameras is around 11m (35ft) at ISO 100. This means a subject 5m (16ft) away is going to need an f/2.2 aperture at ISO 100. With the 270EX II having a guide number of 27m (88ft) at ISO 100 then f/5.6 is needed. To me it's simpler to push the ISO two stops more and use the built-in flash.
However if your camera's pop-up can be a speedlite master and you want to use the 270EX II off-camera then it's a different story. It makes sense. However if off-camera flash is your aim I think you'd be better going for the 320EX or 430EX II if off-camera flash is the aim. The last two also give you yet more power and the ability to orient the flash body towards the camera - so it can receive the pulsed light signal that controls it - and orient the head of the flash at the subject. You can twist the head on the 270EX II
As of now the 430EX II is only $5 more than the 320
Along with more power, the 430 has a real manual mode that will be beneficial for off camera work.
