(1) Fuji Z series has always been a periscope lens design, with slim appearance and average image quality. You should know it well. Fuji's camera configuration is generally high, but the actual imaging is weak. Its flagship product is the F series which best represents Fuji's level.
(2) If you buy a camera in Taobao Shenzhen, you can buy real parallel imports or refurbished second-hand, depending on the specific merchants and specific models. And it is difficult for ordinary people to judge whether it is refurbished. Refurbishers in Shenzhen and Guangdong can make all new things, from shells to packaging boxes and instructions. Personally, I don't think it is necessary to judge whether to transform this low-end camera, but to explain the situation by looking at the imaging effect after taking pictures. In addition, there is no warranty for parallel cameras, and the other party promises the store warranty, which is pure nonsense and has no credibility.
(3) Since the picture quality of Fuji Z7 1 is not so good, there is no need to take the risk to buy it (it is not a good model itself). You might as well have a look at the authorized cameras in JD.COM. There are many choices for low-end cameras, such as the new Fuji L50, Canon A series and Nikon L23. Not much better than Fuji Z7 1, at least much more reliable. Generally, you choose high-end parallel cameras, and the price difference is big. For a low-end camera with a small price difference, don't worry about not being able to buy it in order to save less than 100 yuan. 100, just buy insurance for the camera.
