Canon EF 15mm f/2.8 Fisheye Lens for Canon SLR Cameras (Discontinued by Manufacturer) Features : Measures 2.9 inches in diameter and 2.4 inches long and weighs 11. Display side-by-side to save as a side-by-side image in VR180. The left and right images are reversed in Canons VR system, so we will swap them. Execute Fisheye to Equirectangular Conversion 7. To test if the lens has the back-focus we use a special target scale which is easy to be hand-made: you should print it with a laser printer, stick it to the piece of thick carton and make some slits to make it more stable. As much as possible, align the crop area with the center of the fisheye image, and stop dragging the mouse to crop the area.

Read more. īack-focus means that when focusing on some focusing point the lens misses backward so that the depth of field shifts back, too. 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. the audience can be immersed in virtual worlds. Digital planetarium gives the possibility to project different images on the dome of the planetarium and thus creating the presence effect, i.e. El RF 5.2mm F2. One of the unusual ways of using Peleng 8mm fisheye lens is its application in the projectors of digital planetariums. Here you can find results of this "battle": We had placed them face to face, and analyzed their pros and cons. We have compared two Fisheye lenses the Peleng and Samyang. Diagonal or full-frame lenses, the image circle of which is circumscribed around the film, so that only the diagonal angle of view is 180 o. Circular lenses, which give a circular image within the film frame, and thus they have the angle of field of view 180 o in any direction.Ģ. In practice, there are two main types of such lenses:ġ. A great zoom fisheye to capture beautiful images. 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.
