Studio Flash Lamp Ulanzi F12 GN12 Hotshoe Flash for Camera, Phone and ISO Shoe

The Ulanzi F12 GN12 Hotshoe Flash is a compact studio flash lamp designed for attachment to camera hotshoes and ISO-style accessory shoes on phone rigs. With a guide number of 12, this flash provides a balance of portable power and small size, offering both flash and continuous lighting modes suitable for on-location work. The product is engineered to support portrait, product, and general-purpose photography where a small, mountable light source is required.

Advantages

The Ulanzi F12 combines a lightweight form factor with GN12 output to deliver usable illumination without a separate light stand. It can be mounted directly on DSLR or mirrorless camera hotshoes or on phone rigs with an ISO shoe adapter, enabling quick setup and framing. The unit supports both flash pulses and continuous light, making it suitable for mixed photo and video workflows. Its compact footprint and straightforward controls make it easy to position and operate in tight spaces or on the move.

Suitable for

• Portrait photography on location and in home studios

How to use

Attach the Ulanzi F12 to the camera hotshoe or to an ISO-style shoe on a phone rig and secure it in place. Power the unit according to the supplied battery or power method and select flash or continuous mode depending on the shooting requirements. Adjust output level to achieve the desired exposure and position the camera and subject to take advantage of the directional light. For flash use, synchronize the camera with the flash using the hotshoe connection; for continuous light, frame and expose as with any constant light source.

Usage recommendations

Use the flash at lower power settings for close-up portraits and product shots to reduce harsh shadows; increase distance or diffusion for broader, softer illumination. When shooting video with continuous mode, monitor color balance and exposure on your camera or phone and consider adding a small diffuser to soften highlights.
