The package came with a waist bag (a rectangular bag with a belt hole on the back side, double-opener zipper for the top side) including different thread-on adapters for mounting the flash (from 52 mm to 77 mm, not for lenses having thread diameter greater than 77 mm). User manual is in CN and EN. The F/ number reading with Nikon camera is accurate (tested with G lenses). The exposure compensation operation is intuitive - just played around to figure out which button to push (but the LCD display shows "+" like a division sign). Not noticing the flash showing focal length information, or distance information, but assuming the TTL sensors working because the test shots show proper lighting and EV changes. The test shots were taken with 28-300 mm VR on FX Nikon, at the 300 mm end at the closest focus distance, F/5.6 through F/11, +1 EV, ISO 250, 1/100~1/125 handheld, VR off, all shots came out great (better than expected). Basically, this flash allows one to shoot close up for documentary without any tripod. But this could potentially black out anything that is not lit by the flash (either good or bad, depending on use). I am sure the flash is even more useful with a tripod for even lower F numbers and/or more complicated set lighting.Shortcomings are: the product is made of cheap materials when compared to Nikon products. The difference is pronounced in details (edges are not straight, plastic look cheap, etc.) However, this is fair given its price (and the cost behind).
