Nikon D90 brand_Leica Breakthough Photography calls this anThe Nikon D90 is a good quality DSLR camera with a 12mp DX format sensor and pretty solid compatibility with Nikon F mount lenses, from the earliest AF models to some of the newest (minus the E type and AF P models). If you don't care about metering, you can use most lenses all the way back to the earliest pre AI models. Video? Yes, kind of, but it's 720P and not very good. This D90 is in excellent condition, with approximately 3200 actuations.
