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 used PZ42XN on Nikon D5100 and D800 inplace of the built-in flash. It is adequate for direct lighting of subject in relatively small room. I've used Alkaline and Ni-MH batteries (not mixed). While the recycling time and intensity is acceptable, I prefer another third-party speedlight that cost about $30 more because of the following: (1) GN of 200 (Ft) at 105mm /100 ISO (2) External power pack coconnection (3) Capability for wireless TTL Slave (4) Repeating Flash (4)...
Pros: Consistent Output, Easy To Use, Lightweight
Cons: No external power jack, Not For Wireless Slave, Slow Recycling, Weak Output
Excerpt: This flash advertises that it is compatible with D-TTL and I-TTL cameras and I confirm this by going to Sunpak's website and looking at their compatibility list of cameras. Well, with the Nikon D5100, the flash is flawless, but with the D100, it is a hit and miss. The exposure is very inconsistent with the D100. It exposes perfect one time, then under/over exposes the next time.
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: Thirty some years ago, Sunpak had a great little feature, the "Thyrister" which would automatically switch off when the subject had received enough light for the picture. Today with not only the thyrister, but coupled with the TTL feature, it's simply fantastic. i can't say enough GOOD about it. I really don't see the need to buy a Nikon Flash for your Nikon camera when the Sunpak will do the same thing, and for hundreds less. I love Sunpak... D. Swenson Ft.
Pros: Consistent Output, Easy To Use, Lightweight, Versatile
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
