Is the laowa 35mm f 2 8 zero d tilt shift 0 5x macro hard to focus manually?
The site doesn't rate how hard this lens is to focus. What it does say is that the Laowa 35mm f/2.8 Zero-D is manual focus only, with no autofocus and no stabilisation, so every shot's focus is up to you.
On a full-frame body it frames as a plain 35mm, and on APS-C it behaves like a 52mm, so the framing changes with your camera. The Laowa 35mm f/2.8 Zero-D Tilt-Shift 0.5X Macro page has the full list of supported cameras and the framing details. If you're new to manual focus, the lenses guide covers the basic lens choices for starting out.
