Is the laowa 85mm f 5 6 2x ultra macro apo hard to focus manually?
The lens page says the Laowa 85mm f/5.6 2X Ultra Macro APO is manual focus only, with no autofocus and no stabilisation. It doesn't say how hard it is to focus by hand, so I can't give you a verdict on that from the site. What I can say is that at 2:1 magnification the focus zone is very thin, so you'll be moving the lens by small amounts and checking the screen or viewfinder closely. Macro work is usually slow and deliberate anyway.
If you want a full-frame macro to compare, the Laowa 100mm f/2.8 2X Ultra Macro APO is also listed here, though its page doesn't say whether it's autofocus. For the basics on focal length and framing, see the lenses guide.
