I purchased the flash for my Canon 600D and am pleasantly surprised. The device is very easy to handle and is also found in small pockets still space. The illumination is surprisingly good, through the adjustable angle upwards, there are no more red eyes in the photos and bounce flash is possible. Because flash recharges very quickly, also continuous shooting are not a problem. Of interest is the possibility of unfettered flashing and the remote triggering of the camera, which worked immediately and without any major adjustments immediately.
Even in larger rooms the flash is strong enough to lighten and outside it is also suitable as long as the subject is not too far away. Who, however, almost exclusively photographed outdoors, should resort to a stronger unit with a higher guide number, you do not get it as bright as day with this little device, of course.
For my purpose exactly the right Lightning: The device is lightweight, compact and recharges quickly, perfect for interior shots.
