Excerpt: I wanted a flash with manual settings, and many I looked at were $300+. My goal was "shooting" hummingbirds and "freezing" the rapidly beating wings. It wasn't so much for illumination (although that helped with some twilight shots), but for the (use of) the flash to effectuate a higher shutter speed. BUT, though TTL settings worked fine, the flash would not fire on manual settings with my Sony A65.
Pros: Easy To Use, Excellent Value, Fast Recycling, Lightweight, Powerful Output
Excerpt: Got a second one, since a cheapo sold by b&H conked out as a backup. The auto zoom flash angle drives me nuts, but I use diffuser(s) for most of my shots. Love the manual vari-power settings, since the auto settings are fickle on all flash units. B& H did not carry a simple diffuser for it. Shame shame. Still got my old one though. Make your own or buy one of their fancier ones.My old one recycles quickly and has been very reliable.
Pros: Durable, Fast Recycling, Good value, Lightweight, Versatile
Excerpt: I am using this with my Nikon D5300. I had to play with it a little bit to get it to work TTL with the camera but it seems to be working well. The light seems even and well measured. I took some test shots with it at different metering modes (matrix, center, and spot) and it seemed to adjust the light output appropriately.
Pros: Consistent Output, Durable, Fast Recycling, Lightweight, Powerful Output
Excerpt: I have used this Sunpak for 2 years with my Canon 7d and have been very pleased with it. I do mostly event photography and some photo-journalism. I have seen the reviews that say it is superior to Canon of similar price. It is and itn't compared to the Canon 430EX I just purchased. It may be: -Similar guide number. -It has good durablity -Good on camera and off camera with compatable ETTL cord or PocketWizzard. -Buttons are larger and easier to use.
Pros: Consistent Output, Durable
Cons: 7d Menu Does Not See It, No high speed sync, No slave
Excerpt: This flash works great as long as you have it attached directly to the camera, or using a flash cord. But when I tried to use it with radio transmitter for off-camera flash use, it does not work. I don't understand why. But when I use my really inexpensive flash, (just on and off switch), I have no problems with the radio transmitter. It works beautifully, I just can't adjust the flash power.
