Nissin Di622

Check availablity: eBay.

This flash is for the budget minded that just want a dedicated flash to use on camera. It costs about half of the Canon 430EXII and Nikon SB-600. What you lose is some build quality (the locking mechanism on the swivel head is weak and may pose a problem when adding snoots and diffusers), the rear LCD, manual zoom, fine-grained manual control, off-camera power control (it has a built-in slave trigger, but off-camera it dumbs down and becomes a manual flash). Also, depending on version, it may not work with radio triggers.

One design quirk is that the built-in slave will not trigger if there is no pre-flash. However, it will also trigger too early with the more complex pre-flash used by Canon and Nikon for E-TTL/AWL type remote control.

Another quirk is that the Canon version can only be triggered via system-specific pins. It can not be fired from centre contact of the hot shoe. Same restriction applied to the original Nikon version. However, Nikon models produced after February 2010 no longer has this restriction and will work with standard radio triggers.

The zoom head is not manually adjustable. In the hot-shoe, it follows the focal-length of the camera's lens without taking crop-factor into account. Of camera, it is fixed at the 35mm setting.

Øivind S. has used the Canon version of the Nissin Di622 for some time. He reports that he is happy with the unit, given its price-tag. To make it work with cheap radio triggers, he has modified it as suggested by FotoJack. He confirms that this modification works. Here is some additional notes from his message:


  • The E-TTL seems to work well.
  • Optical slave works very well indoors with an E-TTL-flash as master.
  • Comes with built-in bounce card and diffuser plate for wide angle use.

Less good:

  • Unsuitable for use with cheap radio triggers unless modified.
  • Quite large and heavy (it feels as if it is larger that the 580EX2).
  • No locking pin for making it firmly fixed when in the hot-shoe.
  • Optical slave not reliable outdoors in bright light.

Brand profile

Key info

Established: 1959
HQ: Tokyo, Japan
Web: Global, man

Nissin is a Japanese manufacturer of flash units. It differs from almost any other Japanese company I've dealt with by having poor communication skills, not responding to customers concerns, and putting stuff on the market before it is ready. Its manufacturing facility is located in Shenzhen (China) and its sales operation is located in Hong Kong. For all practical purposes, I would say that this is a Chinese company.

The company was founded in 1959, and has produced professional flash units since 1967. In 2007, the company introduced Di622, its first dedicated flash aimed at the DSLR TTL-market.
