Initially I wanted this flash 100 leds for my Sony A77, but for Sony it is proposed that 48 LEDs. Also having a Nikon D7100 I ordered Nikon mount. In fact, with an old Minolta adaptation hoof it works fine also on my Sony. I'm glad. The finish is more than correct. Operation is super simple (no need to press). I recommend. Delivery nickel as usual with Amazon.
