Only 35mm SLR cameras have real fisheye glasses. The focal length is about 8 mm, the image is completely round, and the viewing angle is 180 degrees; A few models can reach 220 degrees, mainly used for scientific photography.
Fish-eye glasses are composed of many optical lenses, which need precise molding and assembly, so they are very expensive. Comparatively speaking, it is much cheaper to buy fish-eye glasses. This additional mirror has no focal length, but it can change the focal length of the original lens. For example, if an additional mirror with 0.4 times is mounted on a 50mm standard lens, its focal length will become 50× 0.42 mm If it is mounted on a 28mm wide-angle lens, the focal length change can be imagined. Special effects that only fisheye glasses can produce will appear in your viewfinder. Finally, try the self-made fisheye device: take a round hole in the spare lens cover, fix a household "cat's eye" mirror in it, and then cover this lens on a head to produce the effect of fisheye lens. This method doesn't cost much, and it can also make you enjoy a little fun after you start working.
15mm and 16mm fisheye glasses are common and suitable for 35mm SLR cameras. 24mm, 30mm and 35mm fisheye glasses are suitable for Mamiya 645(6×4.5cm), Hasselblad (6×6cm) and Pantex 67(6×7cm) medium format SLR cameras respectively.
High-quality fisheye glasses are very expensive, sometimes exceeding $65,438+0,000, while low-priced ones are often of poor quality. If you just want to play, you can try fisheye glasses, which are fisheye glasses attached to the front of ordinary lenses. When shooting, the image actually passes through two lenses, and the result is a fisheye photo with acceptable quality and extremely low price.
Obviously, fisheye glasses are not commonly used lenses. After the basic shot is finished, you can also try to play.
