The outstanding feature of the OP Fisheye was its orthographic projection design, the first interchangeable lens of its type in the world.
If sharpness is the goal, better results would likely be achieved at an aperture setting of f/8 to f/11. Of these, the OP Fisheye-Nikkor 10mm f/5.6 (called the OP Fisheye below) was released in 1968 as the fourth fisheye lens from Nikon, following the 7.5mm f/5.6. If you’re searching for a high-quality fisheye lens at an extremely affordable price, then the Rokinon is the perfect option. It’s an ideal starter lens for photographers who want to start experimenting with fisheye photography. Since it renders blues beautifully, it’s perfect for outdoor use and landscape photography. It delivers excellent performance with flashes, making it ideal for sports as well.
Our verdict...
The chart on the left provides data at a glance. The table on the right provides more data accuracy. When the aperture is stopped down to f/4-5.6, sharpness increases from the center of the frame to the edges. With the exception of extreme edges, a satisfactory level of sharpness is achieved throughout the frame. f/8 to f/11 Vignetting is present in the corners of the frame, resulting in a tunnel vision effect that makes the scene appear to be confined inside a round circle. Hill called this type of lens a whole-sky lens, and is known as the father of whole-sky cameras. However, the name is mysterious. Why was "fish-eye" not used? For a time, "whole-sky camera" and "whole-sky lens" were the names commonly used in the industry. So what was the first lens to be named a "fisheye lens"? After looking into the matter fully, it seems likely that the name originated with Nikkor lenses manufactured by Nippon Kogaku K. K. (now Nikon). It seems that the term "fisheye lens" has been used by Nippon Kogaku K. K. (now Nikon) since before WWII. "Fisheye lens" is noted on design blueprints produced in 1938. In addition, "FISH-EYE NIKKOR" is stamped on a whole-sky camera lens released in 1958. Based on these records, it seems highly likely that the name "fisheye lens", which is now recognized around the world, originated in Japan. II. Circular fisheye and full-frame fisheye 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.
Next let's look at some actual results. Details regarding performance at various aperture settings are noted. f/2.8 (maximum aperture) As the history of fisheye lens development by Nippon Kogaku K. K. (now Nikon) is detailed in Tale 6, I will not cover it here. Rather, with tonight's tale, I would like to consider the person responsible for the naming of "fisheye lenses". By pointing the lens straight up in a street filled with skyscrapers, you can capture a dramatic view of incredibly high buildings. Pointing down from an elevated platform, on the other hand, enables you to capture the miniature city life bustling below. Creative and Surreal Shots
What we Love...
It is extremely difficult to implement this type of orthographic projection fisheye as a spherical lens, so the OP Fisheye makes the front lens aspherical to provide accurate projections.
If slightly softer rendering is desired at the frame peripheries, users should probably try an aperture setting of f/2.8 to f/4. 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. Cameras – LCD screen is heavily worn either by de-lamination or has scratches to it. Rubber grips are starting to come away from the body. This camera was capable of capturing the sky-image above the horizon in a single shot, and we widely used for meteorological observation by the Meteorological Agency, National Defense Academy and NHK (Japan Broadcasting Corporation). 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).
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. 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? The first fisheye zoom developed by Nikon, the NIKKOR 8-15mm offers the versatility of full-frame fisheyes and the feel and look of circular fisheyes – all in one model. Along with enabling photographers to shoot classic full-frame fisheye photos, it also allows users to zoom out to capture stunning 180° circular images. It further offers a 0.34x reproduction ratio for beautiful close-up fisheye images. Who
