What is a Fisheye Lens?

The video introduces fisheye lenses by defining them as ultra wide angle lenses capable of capturing up to a 180 degree field of view. The presenter uses the Canon 8-15mm f/4 L USM as a demonstration, explaining how at the 8mm end the perspective is so wide that you can see the inside of the camera through the viewfinder and even the floor in the shot. He discusses practical use cases, noting that the lens is particularly helpful for indoor group shots where space is limited, or for capturing expansive cityscapes and large architectural subjects where getting far enough away is not possible. The reviewer emphasizes the distinctive bubble-like distortion near the frame edges and cautions that straight lines will appear curved, making the effect not a true representation of reality. He then compares full-frame versus crop sensor behavior, showing how the lens behaves on different bodies and how the 15mm setting provides a pronounced wide-angle view with visible lens elements at the edges. Throughout, he highlights the lens as a kind of specialty tool more suitable for landscape, vlogging, or creative perspective moments rather than standard portrait work, and finishes with practical tips on rental options and suggestions for future lens reviews. The overall tone is informative and hands-on, offering concrete demonstrations, measurements, and real-world scenarios while inviting viewer feedback on what to review next.
