What is the definitive guide to using the ZGR-2a bluetooth dongle by Scott Kivowitz?

Hi, I’m Scott Kivowitz from… How can I help?

There is not a standalone “definitive guide” ebook or manual written by Scott for the Zesty Accessories ZGR-2a bluetooth dongle. What exists is a detailed review and field test describing how it works in practice with an iPhone and a Nikon D800.

In that article Scott covers:

• How it connects (10‑pin on Nikon, USB on some other brands)
• Using the SmartShutter app for single shots, long exposures, timers, geotagging, and extra tools like compass and sunrise
• Real‑world range and reliability tests
• The main drawback: the dongle sticks out and interferes with L‑brackets on many bodies

You can read Scott’s full walkthrough by searching for “Bluetooth Remote Camera Trigger With An iPhone Scott Wyden” and following that blog post.

Are you mainly interested in setup, long‑exposure workflow, or compatibility with your specific camera?
