Have gained me the lightning to occasionally take pictures in low or backlight conditions. It is not a high-power flash but I knew previously. However, suffice fully my needs. I shoot with the Sony a7, a great flash allows the camera to tilt repeatedly. Unwieldy and schwehr came at that. This small Blitzer is hard to spühren. By folding down easily disable set is switched on. Bounce flash and telephoto flash can be set quickly. All around a successful product for the occasional flashes.
