What cameras fit the sony e 18 55mm f 3 5 5 6 oss?
This lens is made for APS-C, and it fits a long list of Sony E-mount bodies. On APS-C cameras it works at full frame coverage. On full-frame bodies it runs in APS-C crop mode, at fewer megapixels.
For an everyday pairing, I'd go with the Sony a6400 or the Sony a6100. Both are small APS-C bodies, and this stabilised kit zoom suits them well.
If you already own a full-frame body like the Sony a7 III, the lens will work, but you'll be cropping and not using the full sensor. It's a fine stopgap, though not the best match. The full range of compatible bodies is listed on the Sony E mount page.
