Nikon AF-S FISHEYE NIKKOR 10.5mm f/2.8G IF ED

Product Information

While resolution is relatively good at the center of the frame, sharpness gradually drops as image height increases. However, even at the extreme edges of the frame, image quality appears sufficient for practical use. In addition, colors are sharp with little bleed. f/4 to f/5.6 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).

The majority of buyers were impressed with the sharpness and image quality the Sigma 15mm offered. They loved its high-quality build and the colors it captured. Customers found it to be quiet and fast and stated that they had a lot of fun shooting with this lens. However, users were disappointed with the fact that the lens cover did not fasten to the unit. 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.

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. 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? Reproduced from data in the Nikon manual, this table also provides some added detail that I input from experience. If you need an affordable diagonal fisheye lens, then the Sigma is a perfect choice. Designed with a gel filter holder, the unit is ideal for filmmakers who experience difficulty with high native ISOs. It can also be used for wedding photography to give a more artistic look, scenic photography, and underwater photography.

Vignetting is the darkening of the corners of an image relative to the center of the image. There are three types of vignetting: optical, mechanical, and natural vignetting.Sept 11: Lexar has launched a new line of affordably priced UHS-II SD cards, the Silver Pro line. Sizes from 64GB to 512GB, write speeds of up to 160 MB/s and read speeds up to 280 MB/s. 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. They also found that it controlled flaring very well and had little color fringing and chromatic aberration.However, customers reported that it took some time to get used to the focus, while some found that images in bright light were a bit overexposed.

Lenses – The lens has dust inside that may affect images. The rubber zoom/focus ring is coming away from the barrel of the lens. The Rokinon FE8M-N 8mm boasts truly exceptional image quality. The unit distorts lines in such a way that makes the captured scene look very intriguing and interesting. Since it distorts the plane of the image completely, it enables photographers to be incredibly creative. In fact, the best results are achieved in manual mode when images are underexposed a bit. 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.The orthographic projection OP Fisheye, on the other hand (Fig. 2.), resolves the celestial image onto the film. The fisheye lens has a wide picture angle, making it difficult to shoot without including strong light sources, but the OP Fisheye (although it only has a single-layer coating) can be used with confidence because it does not suffer from severe ghosting even when the sun is in the image directly. Next let's look at some actual results. Details regarding performance at various aperture settings are noted. f/2.8 (maximum aperture)

The basic lens composition of the OP Fisheye is the same as the 7.5mm f/5.6, but a large-diameter aspherical front lens is used to achieve orthographic projection. Briefly, the lens has two concave lens elements to reduce the 180-degree view, a cemented lens to correct the resulting aberration, and a 5-element convex lens group consisting of a turret-type filter, stop, and a concave lens group to resolve the image onto the film. Even by today's standards this is a very rational lens layout, and Nikon fisheye lenses since have following this basic design.There are other lens manufacturers that also make fisheye lenses that will work on Nikon F-mount DSLR cameras.
