Introducing the OPPO Find X9 Ultra Hasselblad Earth Explorer Kit, a sophisticated name for an advanced photography kit tailored for the Find X9 Ultra. This exquisite product truly lives up to its lofty title.
In contrast to vivo's X300 Ultra photography kit, which offers either a 200mm or a 400mm teleconverter lens, the OPPO Hasselblad kit features a singular 300mm lens. This longer lens can indeed be extended further with the included lens hood.

Inside the box, you'll find a protective case designed for the phone, complete with a compact built-in grip; a lens that comes with a body cap, lens cap, and a lens hood; a filter accessory for attaching the teleconverter to the phone; a filter adapter for 67mm filters compatible with the quad-camera system of the Find X9 Ultra; and a lens collar featuring a built-in tripod mount.
The kit and its components
The tripod collar serves a crucial role in providing a stable mounting point when using the phone and lens in conjunction with a tripod, minimizing stress on the connection point between the lens and the phone.
Additionally, the collar offers a convenient grip for holding the kit while on the move.

This aspect is best depicted in the side view, highlighting the impressive length of the 300mm lens.

It's worth noting that while vivo's X300 Ultra kit appears to be better balanced, primarily due to the shorter teleconverter lenses, the 300mm lens for the Find X9 Ultra is noticeably longer.
However, when fully assembled, the kit transforms the smartphone experience, making it feel very much like a dedicated photographic accessory.
We appreciate the smaller grip featured on the case, which allows you to easily slip the phone into your pocket and use it as a regular device while capturing photos.
In contrast, vivo's X300 Ultra photography case comes equipped with a substantial detachable grip, which, while convenient, makes it cumbersome to return to your pocket when assembled.

To utilize the Hasselblad Teleconverter, you must select the specific mode in the camera’s menu, a process that is slightly less intuitive compared to the straightforward toggle offered by vivo.
Once in the appropriate mode, three on-screen zoom options become available: 13x (native 300mm), 30x (690mm), and 60x (1,380mm). Of these, only the 13x optical option is recommended, as the quality diminishes at the higher zoom levels.

Here are some camera samples taken with the 300mm lens. We invite you to evaluate the results for yourself.
