Fun fact... Sigma 18-35mm f1.8 ART works uncropped on the EOS-R

Title says it all.. almost.​My EOS-R came today and the sigma 18-35 ART APS-C lens works great as a 35mm f1.8 on the R, without cropping down to 11 megapixels.​Unfortunately if you zoom any wider it starts to vignette almost immediately, so don't use it as a wide zoom - treat it like a nice sharp f1.8 35mm prime lens and save some $ if you already have this lens and were thinking of buying one.​You can of course use it cropped to 11 megapixels as if it were APS-C, and use the full 18mm-35mm zoom range.​Examples here via /r/photography https://ift.tt/2QKx1z0
