Can't believe this thread hasn't been updated in a year and a half! Both Tamron and Sigma have recently been licensed by Canon to make RF-S lenses, with Sigma being first to market with an RF-S version of its popular small, light, and sharp APS-C 18-50mm f/2.8 DC DN lens coming in July 2024, and Tamron coming to market a few months later.
Sigma's 18-50 f/2.8, while very sharp and bright, stays smaller and lighter than even the R7's kit lens by omitting IS. (The R7's IBIS has that covered.) No control ring on the other versions of this lens - it's doubtful that they'll be adding one for the RF-S version, since they're racing to have it out very quickly - unless they do what Canon did with its smaller RF lenses, having its Manual Focus ring switchable to act as a Control Ring as well.
When I can get my hands on this it will be the successor to my long-prized EF-S 17-55mm f/2.8 and will stay on my R7 most of the time, only to be replaced by my EF 24-70mm f/2.8L II USM for event shooting.
