关键区别 - 全帧与APS-C
The sensor is an integral component of a camera which captures the light that enters through the camera lens. This light is then converted into an amplified digital signal with the use of the sensor. How the sensor behaves will directly impact the quality of the camera. Not only the sensor but also the size of the sensor is important in a camera. In the past, SLR 35mm films were used to shoot photographs. But now the cameras are referred to as full frame digital cameras. These cameras have a sensor size that is almost the size of a full frame 35mm film. There is another sensor called APS-C, which stands for Advanced Photo System type-C. The这两个传感器(全帧和APS-C)之间的关键区别是大小。
什么是全帧传感器?
全帧数字SLR传感器相当于过去使用的35毫米传统胶片。传感器的尺寸为24毫米x 36毫米。
To record a pixel, the sensor contains a tiny light sensor called photo sites which captures the light and outputs a pixel. If the photo site is large enough, it is able to capture more light. It will also be able to capture weak signals. This gives this sensor the ability to perform really well in low light conditions. The full frame sensor is also able to have a larger depth of field due to the size of the sensor. The viewfinder image will also be bright due to the size of the sensor.
具有全帧传感器的摄像机还具有其他相机无法使用的高端功能。但是,全帧传感器可用的镜头少于APS-C传感器可用的镜头。要注意的一件事是,全画幅摄像头的重量不是因为传感器,而是因为更昂贵,更大和重型镜头。
这些类型的传感器的主要缺点是它们相对昂贵。这些传感器是从昂贵的晶圆芯片中切出的。只能从一个标准的晶圆中切出20个。这意味着相机的整体价格也将很高。但是,由于该传感器提供了更好的视野,并且镜头似乎得到了更多缩小,因此景观摄影师更喜欢全帧摄像头。全帧传感器具有广角镜头的更广阔视野。但是,一些野生动植物摄影师更喜欢基于APS-C传感器的相机来进行额外的变焦。原因,传感器在放大倍数中不发挥任何作用。
什么是APS-C传感器?
aps - c是先进的照片系统类型的意义-C. APS was able to support three different formats. The “C” stands for ‘Classic’ option. These sensors are closer to the size of the APS-C film from which they get there name. The negative size of APS-C is 25.1 × 16.7 mm and aspect ratio is 3:2. This sensor is smaller than the full frame sensor. The size of the sensor is 24 x 16mm; smaller than the 35 mm film size (36 mm × 24 mm). This means that the full frame sensor will capture a larger picture whereas the APS-C will only capture a cropped version of it. Because of that, these sensors are also known as cropped frame. These sensors are used inDSLR,,,,无镜子可互换镜头摄像头和现场预览数码相机。
The crop factor of the APS-C camera is suitable for wildlife and sports photography as it provides a physical distance which is essential in some situations. The cost of the APS-C camera is lesser than a full frame sensor camera as the sensor is less expensive to make. Lens issues are also relatively lesser as the image is cropped.
全帧和APS-C有什么区别?
传感器大小
Full Frame:大24 x 36毫米
APS-C:Smaller 24 x 16 mm
The full frame sensor is capable of capturing more of the scene than the APS-C sensor. The image recorded by a full frame sensor will look cropped when shot with an APS-C sensor.
Price
Full Frame:制作昂贵
APS-C:Cheaper
全帧传感器制造更昂贵。因此,使用全帧传感器的相机也将更加昂贵。
镜头可用性
Full Frame:大的
APS-C:Smaller
与全帧传感器相比,APS-C可以使用更多的镜头。
View Finder Performance
Full Frame:更明亮
APS-C:Brighter
全帧传感器相机的取景器相对更明亮,因为它带有较大的镜子。
画面质量
Full Frame:好多了
APS-C:更好的
更多的细节和更好的动态范围使框架图像质量更好。
相机的身体大小
Full Frame:大的
APS-C:Smaller
全帧传感器很大。由于其尺寸,街头摄影师更喜欢基于APS-C传感器的相机而不是全框架。
支持的文件大小
Full Frame:Bigger
APS-C:Smaller
As the full frame sensor produces larger file sizes, more expensive large capacity memory cards need to be bought. It will also limit the storage capacity of the medium used.
Type of Photography
Full Frame:景观,房地产,产品,艺术和街头摄影
APS-C:体育和野生动植物摄影与宏观。
The APS-C is capable of shooting photos from a distance which makes it ideal for wildlife photography.
噪音水平
Full Frame:降低
APS-C:更高
As the sensor is bigger, it is capable of capturing more light and reduce noise. This, with a better dynamic range, makes the full frame camera even better.
概括:
全帧与APS-C
从上面的比较来看,很明显,这两个传感器之间存在许多差异。全帧传感器能够产生更好的图像,并具有更少的噪音,并支持更明亮,更大的取景器,更宽的角镜,并减少适合景观寿命摄影的景深。这些传感器的缺点是它更昂贵,使摄像头更大,并且必须使用较重的镜头。
On the other hand, the APS-C is less expensive, supports telephoto lens, and great for wildlife photography but it losses wide angle lens effect and, as the sensor is small, the noise is a bit higher comparatively.
但是,最终取决于他或她的摄影师类型。上面强调的事实希望使使用这两种传感器的摄像机之间的决定变得更加容易。
