I have my part for my Sony Alpha 6000, and the NEX gained 7 and deliberately not chosen the HVL-F60 M because this to me would be too big and bulky for the two smart cameras. The performance of the LZ 43, and the LED light (for video recording) is enough for me just fine. Amazingly perfect communication (a reason for me here also a bolt of the same house select how the camera) is matched with the two cameras. Ok - for the NEX 7 is an adapter (ADP-AMA) needed (because of the old hot shoe of the NEX 7), but (with the flash) forms a very stable compound. Since I like A 6000 with the Zeiss Vario Tessar 16-70 (= KB: 24 - 105mm) using the automatic zoom flash (24-105) fits exactly to the focal length of this lens. With the wide-angle diffuser, the illumination angle of the flash is on the focal lengths (KB) 15-24 mm reduced, which in turn precisely to push SEL 10-18 (KB = 15-24) fits. Genial is in this flash option, the swivel angle to adjust flexibly in bounce flash both upward and to the left or right. This I still have so seen in any other Fremhersteller. In wireless flash (with multiple flash units), the manual is somewhat blurred: the built-in flash in the above two cameras does not serve as Master. The HVL-F20M as a master on the camera, the wireless flash with master-slave function (eg, the HVL-F43M as a slave), however, works very well.
