I recommend this flash, the technical requirements can read everything, so here only the statement that I have found in connection with my Pentax Kr, a good, even pricing, alternative. Since I'm only amateur photographer, hand me the setting conditions of the appliance. There is a more professional alternative made by Sigma, but this is again more expensive by several euros. Compared to the original flash units from Pentax (For Canon and Nikon, it is no different) a good alternative. The processing makes a, although only plastic, good impression. The power source should, however, use only high-quality batteries, so you have also enough capacity for good illumination. The flash head can be horizontal and vertical adjust, but is provided with locks that must be pressed in order to adjust the flash head only. This is used to and exercise thing. The integrated diffuser serves its purpose quite well. From my experience, a bouncer is recommended as an additive. The High guide number of the flash does the rest, so 5 stars.
