As we all know, a lot of RF mount lenses have been hard to come by for quite some time. Most of these issues are obviously attributed to the COVID-19 pandemic and all of the supply chain issues that are still ongoing across many industries.

Most of the retailers I have spoken to have been told not to expect inventory numbers to rise until at least mid-August. The unreleased lenses will ship as scheduled in very limited quantities, so if you have preorders in, there's still a chance that you'll get your lens on time.
