About this deal

With orthographic projection lenses, the area occupied by the plane source in the image is proportional to its brightness at the object. It should be noted that this was the world's first fisheye lens for which the close-range correction system ("floating element" design) was adopted. We'll go into the reasons the close-range correction system had not been considered with previous fisheye lenses later. The result, however, was a consistently high level of sharpness in images captured at shooting distances of infinity to extremely close up. Note that there are limitations. This lens does not have a built-in autofocus motor and thus relies on the camera’s motor for autofocus. But not all Nikon camera bodies have that built-in. It mainly affects older models and lower models (such as the Nikon D3X00 and D5X000 series in the DX bodies.) The lens will work on those cameras, but it will have to be manually focused. [ ↩] From September 1960 this system became available in our Japanese catalogues as the "Camera with Fisheye Nikkor". What is the best way to consider a fisheye lens's object plane? At 28 years old, this was a huge question for me. This fundamental theme was a vital to achieving superior image quality. With a fisheye lens, it is good to consider the object plane as a sphere with a dome-like surface with which a photographic subject at infinity spreads over the sky. However, as the entire frame is in focus at infinity, it is okay to consider that light pours through the lens from the flat photographic subject at infinity. When the subject is at infinity, there is little need to concern yourself with the shape of the object plane. What happens, though, when the shooting distance decreases from infinity to a finite distance? What happens at close distances?

Being one of the best fisheyes available today, the NIKKOR 10.5MM stands out to us for several different reasons. Firstly, the ED glass element reduces chromatic aberration, ensuring natural, clear colors, while the rounded 7-blade diaphragm makes out-of-focus elements appear more natural. Secondly, the unit is extremely easy and comfortable to use. Lastly, the Close-Range Correction system delivers exceptional performance when capturing up-close shots. Nikon doesn’t have any dedicated Z-mount fisheyes yet. Presumably, you could use an FTZ mount adapter, but it’s not a combination I’ve experimented with personally. [ ↩] Image B was captured with the trial product not equipped with the close-range correction mechanism, and offering flatter curvature of field. Which image do you think is better? The difference was clear. Consideration of flat plane to flat plane wins. Lens design also had to assure that the image resolution performance would not be degraded even if the aspherical surface was imperfect. Aspherical lens mass production technology, while productivity was much lower than it is today, still existed. The orthographic projection OP Fisheye, on the other hand (Fig. 2.), resolves the celestial image onto the film.The outstanding feature of the OP Fisheye was its orthographic projection design, the first interchangeable lens of its type in the world. Fisheye lenses create distortion, but if you look closely at the scenes you want to capture, you can easily use this distortion to your advantage. In fact, some of the most stunning fisheye images have been captured by putting distortion to the right use. Get Close to the Ground The maximum aperture is f/5.6, which is a rather small aperture, but the image resolution is extremely sharp even to image corners. It has no focusing mechanism, and the focal length is a short 10mm, so there is no out-of-focus even with close objects. The image will be adequately sharp up through about 50cm (1.6 ft.) from the lens even at maximum aperture.

Most buyers found the Rokinon to be excellent for the price and loved its contrast, sharpness, and color saturation. Users were impressed with its build quality and stated that it had a great edge to edge and center sharpness. The aberration characteristics of this lens are unique. There is very little spherical aberration, and curvature of field is exceptionally flat. This also means, however, that dust and marks on the front lens will show up clearly in the image, so you must protect the front lens against dust and damage. This is the same for all wide-angle lenses with large front lens, not only fisheyes, but at any rate cover the lens when not in use, and carry a blower with you at all times. Work to keep it clean. Since these units provide an extremely wide angle of view, they have a lot of distortion. Images will usually have a slight curve around the edges, while the unique look might become overused after a couple of shots. Photographers will have to be extremely selective, as the fisheye is not ideal for everything. How to Use a Fisheye Lens I really enjoy shooting with this lens, and I don’t have many complaints about it. But as a practical matter, I’d generally choose the 16mm prime over it. There are a few reasons for that, including that the 16mm is lower-priced, the 16mm is significantly smaller and lighter, the 16mm has a larger maximum aperture, and I simply don’t really need the ability to shoot circular fisheye (I much prefer full-frame). But each photographer’s preferences will differ.An external viewfinder DF-1 is used to frame the shot, and this is the same finder as used with the 7.5mm f/5.6 lens. Even if you look through this finder, however, you cannot see the unique image created by the OP Fisheye. When you first try it, you will be quite surprised at the difference between what you see in the viewfinder and what you see on the film. It takes a little time to get the hang of. First, a fisheye lens that performed very well at infinity was designed. Then we came up with the new close-range correction system ("floating element" design) that supported consideration of the relationship between object images as a flat plane to a flat plane. We then evaluated two solutions, the design solution and the solution that ensured curvature of field with the dome-shaped photographic subject, with trial production of both. With this trial production, we considered a design that thoroughly eliminated differences other than the close-range correction mechanism. We used these two trial products in tests and to take pictures, that were then analyzed. The pictures taken with those trials remain. Let's take a look at them. When compared to ordinary photographic lenses, the distortion is even greater than with conventional fisheyes. Considering this, as well as the way in which the relationship between the object and image planes is defined, is extremely important. This is because image quality varies depending upon the way in which the relationship between the object plane and the image plane is defined. With common narrow angle lenses, the relationship between the object plane and the image plane is considered as a flat plane to a flat plane. However, with fisheye lenses that have an angle of view of 180° or more, considering the object plane as a flat plane theoretically leads to problems. For example, when a subject is three meters away, the distance to that subject is three meters when it is positioned at the center of the frame. But where is the subject for light from the 180° angle of view? The answer is infinity.

These are the fisheye lenses in Nikon’s current DSLR lineup. Nikon AF-S 8-15mm f/3.5-4.5E ED Fisheye Zoom Lens This is Sigma’s frame-filling alternative. It’s still designed for Nikon FX cameras, but instead of being a circular image in the center of the frame (as with the 8mm), it fills the entire frame. So Sigma is using the unusual “diagonal” term here to refer to it filling all the corners with image. So it’s most directly comparable to Nikon’s 16mm fisheye. It’s an autofocus lens, but the autofocus won’t work on all Nikon cameras (eg. the Nikon 3000 or 5000 series DX bodies). Oct 4: If you shoot with a Ricoh GR camera, whether film or digital, Pentax/Ricoh have announced the 2023 GR Photo Festival 2023. You can find information about entering it here.Nov 15: Nikon has released new firmware for the Nikon Zfc. Only listed change is support for a new model of battery that isn’t yet in stores (EN-EL25a). Due to its incredibly wide field of view, you can get down and up close to your subject to exaggerate the perspective. This results in a low angle that cannot be achieved with a normal lens, creating something truly bold and unique. Avoid Distortion With a Sharp Central Composition Most buyers were extremely happy with the Nikon AF DX NIKKOR 10.5mm and loved the incredibly wide-angle and extremely close focusing distance it offered. Users were impressed with its build and optical quality and stated that it allowed them to take stunning, clear images. However, customers found that the auto-focus did not work with all digital modes, while some were disappointed with the lenses inability to attach a filter.
