I will build something that aids me on digitalizing expensive out-of-print books, What 4K DSLR do you know that is programmer friendly? Asking because I would like to interface it with my PC via USB and use custom-made software to control it, take pictures and (maybe) get send the pictures over the connection to my PC.

Maybe I could work better with an Android phone, tho, but I would prefer an DSLR.

    there are many ways to do that. So it would be best if you tell uus what your requirements are to accomplish your goal of a book scanner.
    The who, the why, and the how.
    Are your books fragile? What's your planed setup? Do you need a glass panel to flatten the book?

    @heyheni the book I plan to star is in good conditions, I would build the project by myself, I don't believe any glass would be required.

    There are book scanners made from Lego Mindstorms. And Raspberry Pi just released it's new 12mxp camera module.

    however if you only need to release the shutter on a dslr you don't need to manipulate a cameras firmware.
    The raspberry pi can act as a remote shutter.

    Get something like a Canon 60D of ebay. And the canon 40mm pancake lens.

    @heyheni yes, 4K for maximum details

    @catholic-emacs 4k is a screen resolution. So in megapixel that's 9.5.
    So the raspberry camera with its 12 mega pixel will be fine? Although more is better for OCR.

    @heyheni my bad. What's the highest cost-effective megapixel resolution DSLR you know for this type of projects?

    @catholic-emacs you know what? get the Raspberry Pi High Quality Camera, it's $50 has a brand new sony sensor. It's fully programmable. Give it a try and if it's not working for you project it was only $50 or you can sell it online.

    And as i said the Canon 60D or 70D you can get for $200 off ebay. the XXD series offers all pro features like remote trigering and flash ports.

    You can get cheap document and book scanners on eBay sometimes. You want to get a scanner that has and angled bead so you can scan two pages of a book while open. It'd probably be way easier than using a DSLR.

    Alternatively, there are top down document scanners, similar to overhead projectors.

    @djsumdog @Nanos didn't know that you could get book scanners on Ebay, I will check that out

    I absolutely forgot about importation costs, Oof.

    Well, I'll juggle between options, I don't mind spending several weekends scanning one book.

    Megapixel != quality though. A tiny lens will probably create all sorts of weird lensing effects. Even chromatic aberration can become significant, but the most common is just a general lack of sharpness, most visible on edges.

    @Nanos I would like to do OCR after, but of course I won't be that naive if I go the DSLR route
