中古 Mastering the Nikon D500（カメラマスターガイド）

The section on practical workflows alone is worth the price, especially if you're new to the D500 and feel overwhelmed by all the menus. I've already gone back to it three times while setting up my sports shooting presets, and everything finally clicks now.

I was pleasantly surprised by how well the used book was organized—the chapter on custom banks alone saved me hours of menu digging. It’s helped me actually understand the 3D tracking for wildlife, which I’ve been struggling with.

The section on autofocus fine-tuning saved me hours of frustration, and the step-by-step workflows are incredibly clear. For a used book, the pages are in great shape with no notes or highlighting.
