Kenko AB600-R AI TTL Flash Nikon

With full support for Nikon TTL, including high-speed sync and a built-in 2.4 GHz radio system, the Kenko AB600-R AI TTL Flash has the capacity for straightforward gun-and-run shooting as well as advanced multi-flash capabilities. When mounted on camera, it is an effective lighting tool with a powerful ISO 100 guide number of 197' at 200mm, a zoom range of 20-200mm, and the ability to tilt from 0 to 120 degrees and rotate 180 degrees. As a TTL-capable unit, the AB600-R can also operate as wireless master or slave flash head with TTL functionality.

The AB600-R recycles from 0.1 to 3.5 seconds and can be adjusted from 1/128 to full power in manual mode while it has a ±3-stop TTL exposure compensation range. The AB600-R gets about 180 full power flashes on four separately-purchased AA batteries, but that number can be significantly increased, and the recycling time shortened with purchase of the optional BP-1 battery pack.
