Very reliable, professional speedlite flash. Using OLOONG SP-690N for over a year and very, very happy that I bought this very great flash for my work. Autozoom, i-TTL, build quality, rotation angles, 2.0" LCD display - all is great in OLOONG SP-690N. Definitely - I recommend it to all owners of Nikon photographic equipment. Read more

- Unbeatable price - Nice power - Works really smooth with my D7000 on-camera - Zoom head is much more silent than my SB910 - Reload time is really good at full power - i-TTL works perfectly on-camera - Does not work with Nikon AWL (Advanced Wireless System) - The remote mode only allows M Mode,... - Unbeatable price - Nice power - Works really smooth with my D7000 on-camera - Zoom head is much more silent than my SB910 - Reload time is really good at full power - i-TTL works perfectly on-camera - Does not work with Nikon AWL (Advanced Wireless System) - The remote mode only allows M Mode, the flash just acts as a sync triggered by a photocell, no communication with the CLS (Creative Lighting System) is made - If used off-camera you must hit the cell DIRECTLY, the rebounds from the walls are useless - i-TTL does not work when the flash is off-camera - Auto FP (High Speed Sync) does not work when above 1/320 sec. I don't know why a Nikon flash needs a Canon battery pack. Instead of using a battery pack for Nikon this flash only accepts the Canon battery pack (available at DX) I will buy this flash to use it on-camera o with radio triggers in M Mode to make on-location photo sessions with any light modifier as it power is really good.

Nice LCD display, easy to read with all needed basic information. Wireless mode works great with Nikon D7000. TTL mode works! Fast sync 1/320! FP mode! Fast low light assistance focusing. Zoom noise can be annoying. Slow recharging sometimes. If it proves to be reliable with time, I'll probably buy another one. Great product! Great service (DX!!!)! I'm fully satisfied for the moment.
