Factor de multiplicación de la distancia focal, https://es.wikipedia.org/w/index.php?title=APS-C&oldid=130120961, Wikipedia:Artículos que necesitan referencias, Wikipedia:Artículos con identificadores Microsoft Academic, Licencia Creative Commons Atribución Compartir Igual 3.0, FujiFilm X-100: 23.6mm × 15.8mm (4288 × 2848 Pixel, 3:2, Crop 1,52), Negativo APS-C: 25,1 mm × 16,7 mm (Crop 1,43), Negativo APS-H: 30,2 mm × 16,7 mm (Crop 1,25), Negativo APS-P: 30,2 mm × 9,5 mm (Crop 1,37). [20] Several third-party lens manufacturers, such as Tamron, Tokina, and Sigma, also manufacture a range of lenses optimised for APS-C sensors. This can be overridden by the user if desired. What this means is that a 35mm lens on a Fuji X-T3 is the equivalent focal length of 52.5mm on a full frame camera. ◉ The crop factor is also used on the aperture to give us the maximum effective aperture equivalent on a full-frame camera. It is therefore also equivalent in size to the Super 35 motion picture film format, which has the dimensions of 24.89 mm × 18.66 mm (0.980 in × 0.735 in). This is approximately a factor of 2 for APS-C vs. FF (both scale with the square of the crop factor). El sensor foveon X3 de Sigma también es APS-C con el mismo tamaño que los sensores (Nikon, Pentax, Sony, Fuji) por lo tanto con factor de recorte x1.5. Such sensors exist in many different variants depending on the manufacturer and camera model. Hence, for practical applications, the image noise of an APS-C sensor cannot be directly compared to either smaller or bigger sensor sizes, as its light-collecting property is largely defined by the overall optical system, rather than sensor area. All DA lenses can be mounted on Pentax film bodies, albeit with increased vignetting. Tevi62, la Fuji XT-2 tiene una pinta fantástica, pero precisamente el que el tamaño del sensor sea APS-C hace que las lentes sean más caras y pesadas. This has several benefits, including lighter lenses and a narrower field of view (which implies "longer" zoom). Whilst Canon uses a factor of 1.6×, the other four brands all use 1.5×. The difference in focusing distances is easy to calculate using my calculations here. And a 23mm lens would be the equivalent focal length of 34.5mm on a full frame camera. Este aviso fue puesto el 5 de mayo de 2012. A 50mm lens on a camera with a 1.5x crop factor APS-C sensor gives a field of view equivalent to that of a 75mm lens on a full-frame or 35mm film camera. Nikon makes DX format lenses for their line of APS-C digital cameras. A real difference, but not massive. ◉ Larger sensors than full-frame, like medium format sensors, have a reverse crop factor. i.e.. the 1.5 crop is only because APSC is compared to 35mm or FF. When mounted on a Nikon FX (full-frame) digital body, by default the camera will automatically adjust the viewfinder to depict the DX frame area and crop the captured images to the DX image size. El APS-C, por tanto, no debe confundirse con el APS-H, de mucha mayor área. Sony has two lines specifically designed for their APS-C cameras—the DT line for their A-mount DSLRs and α SLTs, and the E-mount for their α MILCs. So your Fuji XF 18mm f/2 lens – and what a beauty it is – would be the equivalent of 27mm. SSensor Pixel Size as a Determinant of Digital Camera Image Quality, https://en.wikipedia.org/w/index.php?title=APS-C&oldid=984384491, Wikipedia articles in need of updating from September 2019, All Wikipedia articles in need of updating, Articles lacking reliable references from May 2016, Creative Commons Attribution-ShareAlike License, This page was last edited on 19 October 2020, at 20:43. Since the GFX system has a sensor that is larger than full frame, we can expect our crop factor to be less than 1. :: f/2 X Mount Zoom Lenses? The rear of an EF-M lens is considerably closer to the sensor or film plane than that of an EF (full-frame/35mm) or EF-S lens, making it necessary to ensure that the EF-M lens will not mount on the other bodies. Advanced Photo System type-C (APS-C) is an image sensor format approximately equivalent in size to the Advanced Photo System film negative in its C ("Classic") format, of 25.1×16.7 mm, an aspect ratio of 3:2. To preserve the proportions of the subject in the frame with the full-length and cropped APS-C camera, the focus distance should differ by 1.5 times. Crop sensor cameras or APS-C cameras have smaller sensors, and the resulting image magnification is called the crop factor – as you can see in action in the images above. Nikon’s APS-C sensors measuring 24x16mm have a diagonal of 29mm, while full-frame sensors measuring 36×24 have a diagonal of 43mm, so the ratio difference between the two is approximately 1.5x. These can be physically mounted to all Nikon digital and film SLR camera bodies since 1977. These lenses place the rear of the lens closer to the camera's sensor (referred to as short back focus). More information on the how an why of the Lens Multiplication Factor (also referred to as 'Crop Factor') can be found on WikipediaWikipedia Due to technological challenges and high manufacturing costs, making digital camera sensor sizes that matched the size of 35m… Because of this, devices with APS-C sensors are known as "cropped frame," especially when used in connection with lens mounts that are also used with sensors the size of 35 mm film: only part of the image produced by the lens is captured by the APS-C size sensor. Canon sells an optional adapter that allows EF-M bodies to accept all EF and EF-S lenses. More recently, the company introduced the EF-M line for its EOS M series of mirrorless interchangeable-lens cameras (MILCs). Las cámaras que incluyen un sensor APS-C con sus dimensiones exactas son las siguientes: Crop hace referencia al factor de multiplicación o de recorte; es decir, cuánto más pequeño es el sensor respecto a una imagen en una película de 35mm. Micro Four Thirds cameras have a focal length magnification factor … The X-T30 makes use of the same APS-C-sized 26.1MP X-Trans CMOS 4 sensor as the X-T3, ... and a higher 1.25x crop factor that makes framing distant subjects easier. Be In the Know. A 50 mm lens on an APS-C format (crop factor 1.6) images a slightly smaller field of view than a 70 mm lens on a 35 mm camera. Fujifilm X-T4. Style and substance with this well featured and attractive option. These lenses are available in focal lengths that offer similar field-of-view as lenses previously available for 135 film. The Future of Digital - Full Frame or APS-C? (I go through all the math below) We call it crop factor because it's literally like cropping the edges of the sensor: When you use a 50mm lens on an APS-C camera, you are basically zooming in to an 80mm point of view because the sensor is smaller.
