Please know you will have to find the textures on the blend file. A simple fix for the seller to avoid the customers from doing this is ticking the "Automatically Pack Resources" under "File" then "External Data." If you are new to blender you might have trouble getting this file to work properly for you. Yes the geometry has bad topology but the image textures/normals help hide those mistakes. Some of the details are added in the normal image instead of it being modeled to the geometry. Like the screws and ridges of the lens for example. The lighting is an HDRI image so make sure you can fix that too. Everything will show up purple with terrible geometry when you open up the file. Honestly I am positive this project file is cursed. Goodluck.

This model is great, super high quality, and super easy setup.
