Re: Pi-Scan and Canon a2500 - trouble connecting

Re: A2-A1 scanner

Hello, gus, two years later. The Nikon D3500 you mention has 24 megapixels or 4000 x 6000 pixels.

Re: HoverCam ImPress Book Scanner

Can 5 megapixels really give good pictures of a printed legal-size magazine page? Their current products all seem to be 3 (T3) or 5 (T5) megapixel cameras.
