Question: Will this work as a light triggered slave flash?
Document: This is really excellent speed light camera flash for inexpensive price. For a entry level photographer, this one is for you. This is also good for portrait photography. You can use with the hot shoe or slave mode. Highly recommended this product.
So far, I have no complaints, as far as the unit doing its job. Works perfectly for beginners, as a backup flash, as a slave, or even a main light. Seems a bit flimsy -- although I've already dropped it twice within two weeks of having it and it's still held up. However, I still recommend handling it carefully. I will try to give an update concerning long term use.
This flash is pretty neat for the price. It doesn't work well with a Nikon D3200. The flash isn't fast enough to match up with the camera in some settings, creating a half black photo.I don't know everything about the technical aspects of my camera, but this is a great deal for someone using auto settings outdoors. It did a decent job for a wedding as well.
THis flash works pretty good. I would use this if you are on a budget for a external flash. .
Great flash! Especially for the price! You get far more than you pay for. I have been using it for about four months now and I have been very pleased.
Does exactly what I need it to do, be a simple to use manual off camera flash. It is cheaply made but it works so I'm happy with it.
Fabulous manual flash, I now own two of them! Super fast recycle time and easy setup when I am out on location! I bought one similar to these at a camera seminar for three times the amount! Great product and fast shipping!
nice at a Great price
Why spend hundreds of dollars on a speedlight when you can get a great one for less than $35?! I was skeptical when ordering this, but I figured I would give it a try for the price, I couldn't be more pleased with my purchase! Great deal, great product.
Everything works well with this.Good product, no issue with it. Valuable price.it's do the job how it has to.Quick shipping.
Answer: Yes in a way! It has a setting on it to switch to be in a slave mode but it is best to always use a remote like a pocket wizard or cactus! This is a great flash for the price, I have been shooting pro for 29 years and shoot nikon but recently bought a few of these! Work great!
