Is the zeiss touit 50mm f 2 8 macro good for product photography?
Yes, it's a good fit for a lot of product work. It's an autofocus 1:1 macro, so you can get close enough to show fine detail and texture at life size, which is most of what product shots ask for. At f/2.8 the depth of field is shallow on APS-C, so stop down if you need more of the object sharp. It isn't stabilised, so a tripod helps.
It's made for APS-C, so I'd pair it with a body like the Sony a6700 or the Fujifilm X-T5. It mounts on Sony E and Fujifilm X. On a full-frame Sony body it works in crop mode at fewer megapixels, which matters if you need large files.
