If you want to buy for the first time a flash, this one will be quite the case to begin and develop the techniques of flash picture (flash indirect ...). It has a good power but seen to decrease from what is stated by the manufacturer. It has an indication of "flash range" and an indication of "flash zoom" only in TTL mode and if the flash is oriented directly (which is not the most appropriate use and most used make the flash picture) !!! It is very easy to use and set up (especially if you use the flash in TTL mode and the flash setting is from the camera). The functions are basic (no unnecessary and superfluous functions). A button corresponds to a function which is very appreciable. The head does not swivel 180 degrees to the right (or left I do not know) which may pose following problem what one wants to do and the environment in which we find ourselves. No diffuser is supplied with the flash ... I suggest you get one when you will buy the flash.
