Having just taken my new 5D3 for a trip to Singapore (on holiday), and tried to travel light (body plus 16-35L & 24-70L), the only real issue I had was the lack of flash for fill-in, because the 5D3 doesn't have a built-in flash. I have a Nissin Di866 but decided to leave it behind, to save weight and bulk when walking around. And boy oh boy was I right - the heat and humidity made even this 'small' kit a PITA at times. I was never tempted to leave the camera behind though........
So I'm thinking I might buy a 'travel flash'. Something small and lightweight. Hence, the little 270EX is under consideration. Bearing in mind I don't want something that can be used for full-on flash-lit images (I would take the Nissin if that were the case) and only want to be able to fill-in backlit subjects (usually people within a few metres) do you think the little unit is worth buying?
