so i have an eos r and currently use an ef adapter with my older ef lenses because rf lenses are too expensive (i had to get a loan out for this camera i cant afford a lens that is the same price again or more) i want to get something in the range of 14-16mm maybe a telephoto like the 15-35 f2.8 but its again ott expensive so my question is would i be better off getting more EF lenses (the adapter is a little slow with one of my lenses but find with the other two so kinda hit or miss?) or should i get one of the new rf-s lenses like the 18-45 4.5-6.3f stm or the18-150 3.5-6.3 is stm? and just accept that itll be cropped?

When you mount an EF-S or RF-S lens on an R system FF camera the image recorded is a APS-C sized crop of the FF sensor. This means you will lose nearly two thirds of your sensor's resolution for recording the image. There are a no wide angle benefits to using any crop lenses on a FF camera. There are only telephoto benefits.

Have you considered the RF 16mm f/2.8 prime? It is very affordable compared to the RF wide angle zooms.
