Today my flash unit arrived for my 37 alpha. Three days shipping time is ok. The packaging of the flash itself is well thought out. The content, the flash unit, a pocket for a holder for tripod o.ä.und a description / instructions in many different languages. Warranty stickers etc will be also. After unpacking the Blizes I once visually inspected the unit. The processing of the plastic parts is correct. The parts themselves feel "grip" to, almost like rubberized. Bad is that the unit shaky in my Sony adapter plugged it. And I think that after all the rather large body, not necessarily to be held with a plastic base. I think it's a matter of time before that thing breaks. The batteries can be relatively simple insert. A minus for the battery cover. Because one feels or does not hear a snap, etc. when the lid is closed. He skid relatively slightly forward and opens perhaps what has not yet happened to me. The power switch can be operated with feeling. The switch quickly slips times a continue and then you have full unregulated flash output. Still further, a grid, the power is reduced. Well my first picture with TTL setting and normal lens. Camera set to Program AE. Living room, object 1.5m away. Click. , , completely outshone. But time brought the manual out and looked up. Then a fall also, that the swivel head to be locked at 7 ° when close (1m - 2.50m) are made. Then it works also :-) Now continue with normal questions swivel head. Property located approximately 3.5m. Click. , , Top! Super illuminated. Continue with indirect lightning against the white ceiling. Click. , , easily outshines. Perhaps adjust the flash compensation on the camera. Now a flash with the retractable reflector foil. This will push some of the light forward. This, which is the swivel head upwards, this small film falls back here often to the device. Fortunately, I have with me ordered individually an external part. This reflector film worthless. When using the test button, for which one needs a little fingernails, the button you use it rarely, invites the flash in about 3-5 seconds to complete. Depending on the battery status. If you fold down the wide conversion lens (17 ° wide angle), the data exchange between the flash and the camera has stopped working. Since it is expected to guide number etc :-) The motor for zooming is not the quietest, but does not interfere. The bag is made of sturdy outdoor fabric with a look solid Velcro. Inside is still an extra pocket for spare batteries. I do not use the bag, because I have a photo backpack. Conclusion: More money, I would not spend on this flash. The performance is more than ausrechend. Relatively well-made. Largest Mankro for me the feet, wobbly and delicate. For normal photographer I would recommend this device.
