Just return it before the test is complete.
Nikon lets everyone in the US get their hands on a full-frame mirrorless Z5 camera with its "worry-free" yellow program. The idea is simple – select a Nikon Z5 package from the website, make payment, and receive it to use for 30 days. Don't you like it anymore It's good. Nikon will include a return label and you will be refunded full price after your camera package is received and verified. Just make sure you do this before the test is finished.
The program offers three camera kits to choose from, including the Z5 camera body only or with either a 24-200mm or 24-50mm kit lens. Whichever you choose, each option comes with a 16GB memory card, expert help, and a 30-day worry-free trial.
If you like the Z5 after the month is up, you can just keep it. Unfortunately, this is only open to US residents, and the program ends on November 30, 2020. So if you're looking to try a full-frame mirrorless camera, this is definitely an option. You can check all the details on the Nikon website.
