In conjunction with a Canon PowerShot S5 IS the flash works perfectly. The settings are very easy mE. The adjustability upwards and sideways, as well as built-in (sofa) additional diffusing screen and the easy additional white reflector are my requirements probably more than satisfy. This thing makes a good impression. Even the battery replacement is very simple. I use this flash Eneloop batteries (4 x AA 1.2 V), the charging times I find until now very acceptable. For this price I got in any case more than I expected.
Who has higher claims, wants to please a unit in a higher price range - his claims accordingly, buy.
