Review on K&F Concept Camera Flash - KF-570 II Speedlite with LCD Display: Canon and Nikon DSLR Compatible by Vangele Carson

Included is a belt pouch (rectangular pouch with belt hole on the back, double zip on the top) including various threaded adapters for attaching a flash ( from 52 mm to 77 mm, not for lenses with a thread diameter of more than 77 mm). The user manual is in Chinese and English. Nikon camera F/ values are accurate (tested with G lenses). Operating exposure compensation is intuitive - just play around to figure out which button to press (but the LCD shows "+" as a division sign). Not noticing the flash showing focal length information or distance information, but assume the TTL sensors are working as the test shots show correct lighting and EV changes. Test shots were taken with 28-300mm VR on FX Nikon, at 300mm end at minimum focus distance, f/5.6 to f/11, +1 EV, ISO 250, 1/1001/125 handheld, VR off, all shots came out great (better than expected). In fact, this flash enables close-up documentary shooting without a tripod. But it can potentially darken anything not lit by the flash (good or bad, depending on usage). I'm sure the flash will be even more useful with a tripod for even lower f-numbers and/or more difficult lighting. Cons: The product is made of cheap materials compared to Nikon products. The difference is noticeable in the details (the edges aren't flat, the plastic looks cheap, etc.), but that's fair considering the price (and the cost behind it).
