Customer Ratings & Reviews

Great for low light / night photography. Has a bright flash, and easy to mount onto photography camera. It is a bit large, but that’s what you need for a big flash photo.

The Sunpak DF4000U External Flash has been a valuable addition to my photography gear. Its automatic zoom head adjusts from 28mm to 180mm, accommodating various shooting scenarios. The built-in bounce card and swivel head, which rotates 180° to the left, offer flexibility in directing light for optimal subject illumination. The illuminated LCD display simplifies customization of settings, and the hot shoe attachment ensures easy installation and removal. Powered by four AA batteries, it's convenient for on-the-go shooting. Overall, this flash provides excellent value for its price, enhancing the quality of my photos across different environments.

Very easy to use. Exceeded my expectations. Worked great in a dark wedding reception setting.

Flash works good. The backlit screen is very easy to see and read. I am giving 4 stars, i mistakenly bought it for the wrong camera system. But suprisingly, it still fires on camera. I did have an incident where i was shooting for a wedding and the flash did not go off,, even after turning off the flash and camera a couple times. Even though it worked the day before the event, as well as the day after.

This has been a very good addition to my equipment. Reliable, pretty simple to use, and honestly, it's all I could expect from a flash.

Great product!! Works as well as my Nikon an series flashes at a fraction of the price

I'm new at all this but loved this product! It was a great price, and was comparable to the name brands. I've also had others that have the name brands, and said it was comparable.

This flash adds more of a realistic tone to my photos and it is super bright. The only down side is that it is a little on the heavy side.

I have been using these for years. This is my first time with this brand. I cannot brag enough. Simple to use!

Flawless connection and integration. The light is bright and makes portrait pictures a snap.

Gets the job done. Good for beginners and experienced photographers needing an external flash to conduct business.

Works amazing! Didn’t like that I have to buy batteries for it but still amazing!

This external flash gives that extra boost you sometimes need above the built-in flash unit or the small one that often comes with the purchase of a camera kit.

Works very well with my Nikon D500 and was a great buy in a pinch!

I don't use flash often and I am a beginner. The flash seems to have good functionality and power. It makes a significant difference in lighting my subjects and enhances my photography.

its good but high speed sync is not available. Otherwise for light fill it is a good option.

Great product and very easy to use. Futs the camera perfectly and works great as a standalone flash

Great item definitely recommend .it's a little heavy but it's worth every penny .

Simple and easy to use. Purchased for my son to use in High School. It's a fifth of the price of the name brand and performs well. Perfect for any beginner or advanced photographer.

Compatible with my Nikon P950 and any other camera I decide to get in the future. I like the remote flash feature so that I don' t have to connect it directly to the camera. Offers very good flash lighting and comes with a travel case and starter batteries.
