Is the laowa 65mm f 2 8 2x ultra macro apo good for product photography?
Yes, I think it's a good pick for product work. It's a 2X ultra macro, so it gets close and shows fine detail, which is most of what product shots need. On APS-C it frames like about 98mm on full frame, so you can step back a little and still fill the frame. At f/2.8 the depth of field is shallow, so stop down when you need more of the object sharp.
It's manual focus and not stabilised, so use a tripod and take your time focusing. For bodies, the Fujifilm X-T5 and Fujifilm X-H2 use the lens at its native APS-C size. If you already have a Sony a7R V, it works too, but in APS-C crop mode, so you give up some resolution.
Full details are on the Laowa 65mm f/2.8 2X Ultra Macro APO page.
