Wide angle with big aperture7/28/2023 ![]() ![]() In cinematography, a lens of roughly twice the diagonal is considered "normal". This large image circle enables either large tilt & shift movements with a view camera, or a wide field of view.īy convention, in still photography, the normal lens for a particular format has a focal length approximately equal to the length of the diagonal of the image frame or digital photosensor. Ī wide-angle lens is also one that projects a substantially larger image circle than would be typical for a standard design lens of the same focal length. This exaggeration of relative size can be used to make foreground objects more prominent and striking, while capturing expansive backgrounds. This type of lens allows more of the scene to be included in the photograph, which is useful in architectural, interior, and landscape photography where the photographer may not be able to move farther from the scene to photograph it.Īnother use is where the photographer wishes to emphasize the difference in size or distance between objects in the foreground and the background nearby objects appear very large and objects at a moderate distance appear small and far away. In photography and cinematography, a wide-angle lens refers to a lens whose focal length is substantially smaller than the focal length of a normal lens for a given film plane. Also note that at small focal lengths, more of the scene is included. By changing the focal length and adjusting the camera's distance from the pink bottle, it remains the same size in the image, while the blue bottle's size appears to dramatically change. Three images depict the same two objects, kept in the same positions. ![]() Sensor-shift OIS is currently limited to the main lens on the iPhone 12 Pro Max.How focal length affects photograph composition. However, switching to auto-focus will be useful for closer wide-angle shots.Ī recent Digitimes report also suggested that the ultrawide lens would get sensor-shift OIS (optical image stabilization), which tends to be more effective than lens-shift OIS as the sensor is lighter and can be moved more rapidly to counteract camera shake. This might sound surprising, but isn’t generally a huge issue in very wide-angle lenses as they are mostly used for landscapes and cityscapes, where everything in shot is far enough away to be in focus. The current ultra-wide lens is fixed-focus. There are pros and cons to adding elements to a lens, but when a manufacturer takes an existing lens design and adds elements, this is generally done to reduce distortion, which is especially important in wide-angle lenses.įinally, he expect the ultra-wide lens to get auto-focus for the first time. Second, sources indicate that the number of elements in the lens will be increased from five to six. ![]() In particular, it should allow for sharper and cleaner night shots. All other things being equal, that would let in more than twice as much light, significantly improving the low-light performance. While the main (wide-angle) lens may be largely unchanged, Kuo has previously said that we can expect three improvements to the ultra-wide angle lens on the two Pro models.įirst, he expects the aperture to be widened from f/2.4 to f/1.8. That said, everything helps, and it continues the trend in iPhones and other smartphone cameras toward ever-wider apertures. We estimate that Sunny Optical will ship the iPhone 13’s 7P wide-angle lens to LG Innotek as soon as May.Īlthough a wider aperture allows in more light, so improves low-light performance and allows shallower depth of field, the difference between f/1.5 and f/1.6 is less than a quarter of a stop, so the real-world difference will be incredibly small. 13 Pro Max’s f1.5 7P wide-angle lens), Sunny Optical’s order is the most in demand item. Since the iPhone 13 mini, 13 and 13 Pro share the same f1.6 7P wide-angle lens (vs. It is expected to ship in 2Q21.īenefiting from Sunny Optical’s production capacity and the advantages of Apple’s own lens design, we expect Sunny Optical will successfully pass the quality verification of iPhone 13’s 7P wide-angle lens order in the near future. Sunny Optical is expected to pass the quality verification of iPhone 13’s 7P wide-angle lens and receive an order. ![]() The other models will, he says, stick to the f/1.6 version. The wide-angle lens being made for the iPhone 13 Pro Max is said to have an f/1.5 aperture, which is slightly wider than the f/1.6 one on the current iPhone 12 line-up. The report says that the wide-angle camera on the largest of the four models will have a marginally wider aperture than the iPhone 13 mini, iPhone 13, and iPhone 13 Pro … Noted Apple analyst Ming-Chi Kuo is out with a new supply-chain report that indicates that the iPhone 13 Pro Max will have a slightly better main lens than the rest of this year’s lineup. ![]()
