The fisheye effect does not come from the wide focal length, but it comes from using a lens that is not rectilinear. A rectilinear lens is one that, despite the focal length, will still ensure that there is no barrel or pincushion distortion: that all straight lines remain straight, not curved. Technically, it ensures that the image is the image that would ...


Yes, it is lens dependent. What you are looking for are rectilinear lenses. In order to have the least possible distortion, you will also need to either keep your lens perfectly horizontal or get a lens that allows shifting, like this one. Some distortion can be removed in software, e.g. Lightroom or DxO.


What is too noticeable is up to you an/or the people watching your images. There are two different effects that causes the distortions commonly seen in wide angle and fish eye lenses. Look at this answer for a good explanation of them. These two kinds of distortions are more or less present on all wide lenses and there are no single focal length where these ...


Simply put, the distortion isn't so much a result of the lens as it is the angle of view. Since you are seeing things that are almost directly out to the side, you are seeing them from the side rather than the front. You can apply a rectilinear correction, but doing so will result in forcing the perspective to not match up with what you are actually seeing ...


There are several problems transforming the curvilinear perspective of the wide angle GoPro lens to a rectilinear one. The transformation stretches the image in certain areas and compresses it in others. This lowers the image quality as new pixels are created as approximations and interpolations from the information in the original image. There is also a ...
