The verdict
The $600 price gap between these lenses forces a choice between the f/2.8 maximum aperture of the 16-35mm and the wider 14mm focal length of the 14-35mm.
Choose the Canon RF 14-35mm F4L IS USM if you prioritize portability and versatility for landscape photography. Its 540g weight and 0.38x maximum magnification make it a more agile option for close-up detail and long days in the field.
Choose the Canon RF 16-35mm F2.8L IS USM if your work demands the light-gathering capabilities of a constant f/2.8 aperture. This lens is the necessary tool for low-light environments where the extra stop of light is more critical than the 14mm wide-angle capability.
