A fisheye lens is an ultra-wide-angle lens that has angle of view 180o or more. The design of such lenses and their shape are really to some extent similar to the organ of sight of fishes. Perspective distortion in such optical systems cannot be neutralized, and the lens forms abizarrely distorted convex-rounded picture, which is the main distinguishing feature of the fisheye lenses.
In practice, there are two main types of such lenses:
1. Circular lenses, which give a circular image within the film frame, and thus they have the angle of field of view 180o in any direction.
2. Diagonal or full-frame lenses, the image circle of which is circumscribed around the film, so that only the diagonal angle of view is 180o.

When using 20D a few times I tried to use 8mm Peleng Fisheye Lens which was the most cost-saving option of Fisheye that it was possible to find with reasonable quality but which I had never had. When I proceeded to full format with 5D MKII Peleng turned to be not “useful”, since it made a circle on the sensor, it was intended for APS-C. However the same producer, Belomo, launched Peleng 17mm f2.8 which can be used in dSLR in full size. |

One of the unusual ways of using Peleng 8mm fisheye lens is its application in the projectors of digital planetariums. Digital planetarium gives the possibility to project different images on the dome of the planetarium and thus creating the presence effect, i.e. the audience can be immersed in virtual worlds. Earlier planetariums projected only celestial objects (displaying the stars, the planets and their orbits, simulating celestial phenomena such as meteor showers etc.), however now it is possible to show any images like cartoons, short films and videos, including, for example, simulation of flight to the stars or your own images and videos.

Now I would like to talk about this Russian lens that takes photos like this one. There will be one more article where I will compare how it works with the film or digital sensor. So, Peleng 8mm f3.5 Fisheye Lens. It is a circular fisheye lens that covers 180 degree field if used with 35mm film. This film is usually bought on eBay or with the help of numerous online and offline sellers, it is not expensive so you will have to pay only about 300-350 dollars. You might have read a lot about this lens which is first of all positioned as the lens for fun and experiments but surfing the russian part of the Internet you will read about its exciting possibilities. Native country of Peleng supposes it to be a serious lens. I could use this one for about 4 months and yes, it was very interesting to be a Peleng owner so I decided to describe defects just to let future buyers know. But you have to keep in mind that some of these drawbacks depend only n my choice of lens-camera combination and they probably won't appear in another combinations.
