Hi all!

I'm currently using the Canon 80D (which i upgraded from the 60D) with the Canon EF-S 17-55 2.8 (great lens!)

I have considered upgrading to full-frame before, but the price and size threw me off. Now with the new EOS RP (this might be rushed but..) I'm thinking this could be it.

If I get the new EOS RP and use it with my current lens EF-S 17-55 2.8 will it effectively be 17-55mm full-frame or will it be the conversion ?
In other words, will the field of view be the same, or will it become ultra wide?

Thanks in advance for the answers!
