2. Anamorphic Comparison
Neither Canon EF-S 18-55mm f/3.5-5.6 IS II or Canon RF 15-35/2.8 L IS USM are anamorphic lenses.
Winner: Tied — Neither have this feature
Regarding anamorphic: Anamorphic lenses are usually used on cinema cameras and squeezes the image when its recorded, which gives the final, stretched out, image oval bokeh and a different angle of view. The most common lenses, however, are not anamorphic but spherical, which gives a spherical bokeh and is a much cheaper lens design.
3. Lens Type Comparison
Both lenses are Zoom lenses, which means that you can choose both Canon RF 15-35/2.8 L IS USM or Canon EF-S 18-55mm f/3.5-5.6 IS II if you're looking for that type of lens.
Winner: Tied
Regarding type: There are two types of lenses; zoom lenses and prime lenses. Prime lenses have a fixed focal length and cannot be zoomed, while zoom lenses have a focal length range and can be zoomed in to get closer to the subject. Prime lenses are usually lighter, cheaper and let in more light. Zoom lenses are more versatile but are more expensive since they require a more advanced lens design.
