Q&A:
My digital camera has a built-in flash. Why do I need another?
br>Built-in flashes are only effective to 8-10ft or less. This high power flash greatly extends the range!
The built in flash units of digital cameras are on average effective to only about 8-10 feet, and that’s when your lens is at its widest-angle setting . When you want to zoom in on the action (towards the telephoto end of your zoom range) you’ll find that your built in flash does exactly opposite of what you want, and its

Low Cost Works Well,
I ordered this product without high hopes because the price was very low. I have been pleasantly surprised, it does what it’s supposed to and that’s all you can ask for. I would recommend this to others seeking a low cost digital slave flash, the price is definitely right.

|not a bad deal,
This flash works, and it is a great deal (for that price). You get about 50 flashes on the 2 aa bateries that it requires

|Fit issue with some Nihm. Guide number is ~6m, draws at least 0.2A when on.,
First, this unit doesn’t work with many brands of nihm (including all the precharged types like eneloops) due to the design of the battery door. This is because those batteries have slightly different profiles on negative end to standard dry cell AA’s, namely the door will not make contact to the negative end. You can fix this as I did by taking off the metal contact piece inside the door and bending the neg “nipple” towards the cell.
There seems to be no prior review which actually referenced power or other more technical specs, so I measure this flash against manual operation of the built-in unit on my D40.
The D40 in manual flash mode is known to have GN ~14, and allow fractional step adjustments. Using that and correlating w/ the built-in histogram, this “Neewer” has about 1/6 the power of a full blast (right between 1/4 and 1/8 settings). Therefore, the neewer has a relative GN of Sqrt(14m^2/6) ~= 5.7m, or not very useful as a hot shoe flash for better cameras.
That’s around the power rating of built-in flashes on larger/higher end point and shoots, or the new crop of mirrorless slr’s (eg pana gf-2, sony nex). On those units, it would double the total light output and increase the range of the flash (using this as a slave) by factor of ~1.4. Not very strong, but commiserate w/ the price.
Other significant spec include a hot shoe trigger voltage of 4-6v depending on the state of the battery, and charge current from the AA’s start at 1.5A or so and drop to 0.2A after a few sec and stays there even when the unit’s doing nothing. This means you should turn it off when not operating since it would drain new batteries in about 10 hours from just being turned on (standard ~2000mah batteries).
