The perspective of lightweight telephoto lenses is significantly more focused on the main subject compared to standard lenses. The depth of field is already relatively shallow, rendering only the important parts of the subject in sharp focus. This characteristic is particularly beneficial in portrait photography: the foreground and background are blurred, while the face stands out in relief. A specialty of Canon is an EF telephoto lens that can soften the subject when needed. However, there are countless other opportunities beyond portrait photography to utilize the advantages of lightweight EF telephoto lenses in creating attractive images.
