What is the frame of the camera and what is the effect on taking pictures
is a higher level of crushing people. Have you heard of this saying, the bottom here is the picture frame, which can also be understood as the size of the sensor. In the film age, the sensor, frame, and bottom all refer to film. In the digital age, the sensors are generally CMOS, and the sensors of some professional instruments are still CCDs. So what is the frame of the camera and what impact it has on taking pictures, let’s discuss it together today.
What size does 01 frame have?
First, let’s talk about the frame size, that is, the size of the sensor, so what is the difference in sensor size?
It can be said that the sensor size of each camera device is different, and due to the limitation of the product volume, the sensor size of many devices is also very limited.
For example, for mobile phones and drones, the maximum sensor size is 1 inch, and only very few products have such specifications. The sensor sizes of other products are all less than 1 inch.
Except for 1 inch and smaller than 1 inch sensors, other size sensors are mainly used in cameras and video cameras. For example, M4/3 frame, APS-C frame, full frame and medium format, these four are the current mainstream sensor specifications.
The M4/3 frame sensor is currently mainly used in Olympus and some Panasonic cameras. The APS-C frame sensor involves the most abundant manufacturers, including brands such as Canon, Nikon, Sony, and Fuji. Full-frame sensors mainly involve camera brands such as Canon, Nikon, Sony, Panasonic, Sigma, and Leica. Medium format sensors are mainly used in products of Hasselblad, Fuji and other brands.
02 The maximum resolution of different frames is different
Next, let’s look at the impact of different frames on the photo. The first is the resolution. The larger the picture frame, the larger the size of the sensor, the easier it is to add more pixels. At present, a medium format camera has a product that is not worth 100 million pixels; the highest pixel of a full-frame camera has reached 61 million; the highest pixel of an APS-C format camera is 32.5 million.
It can be seen that the larger the frame, the easier it is to design a higher-pixel camera.
For users, the same level If the pixel of the sensor is higher, the resolution of the picture will be stronger, that is, the recorded details will be richer. After the shooting, when you come back to view the photo, higher pixels can zoom in to see more and clearer details.
, of course, has disadvantages. Higher-pixel photos are larger and take up more storage space. For example, memory cards and hard drives must be replaced with larger-capacity versions.
The concept of 03 lens conversion coefficient
When we take a picture, the focal length used by the lens is not necessarily the actual focal length of the final image. It doesn’t matter if you don’t understand it, because it has something to do with the frame size of the sensor.
Let’s take the camera as an example. For the focal length of the lens of M4/3 format, multiplying by 2 is the focal length actually used. For example, if a 24-70mm lens is connected to an M4/3 format camera, the actual shooting focal length will change to 48-140mm.
The same is true for APS-C format, most brands multiply by 1.5, Canon multiplies by 1.6. For example, it is still a 24-70mm lens, connected to an APS-C format camera, and the actual focal length used is 36-105mm or 38.4-112mm.
If it is a full-frame camera, no conversion is required. The actual focal length of the 24-70mm lens is 24-70mm.
Therefore, when using different format cameras, the focal length of the lens must be converted by yourself to avoid buying the wrong focal length.
04 Noise control and tolerance performance will be different
Theoretically, the larger the frame, the larger the sensor size, the better the noise control ability of this camera, and the tolerance Degree performance is better. But in actual use, there are many objective factors that will affect it.
For example, for the same full-frame camera, a 61-megapixel camera will be slightly inferior to a 24-megapixel camera in terms of high ISO noise control performance. Of course, this difference will not be particularly obvious.
But if they are 24 million pixels, the full-frame sensor camera will definitely have better noise control ability than the APS-C format camera, which is beyond doubt. That is, under the same pixel level, the larger the frame, the better the noise control ability.
For example, commonly used APS-C format cameras within ISO 2000 are generally available, full-frame cameras within ISO 6400 are generally available, and the top full-frame ISO can be used up to 51200.
The same is true for latitude performance. The larger the frame, the better the performance. Of course, the adjustment capabilities of major brands are different. For example, the latitude performance of Fuji medium format and Nikon full-frame cameras that are common in the industry is obvious to all Excellent.
So far, the introduction about the camera frame has come to an end. If you are buying a camera, then the author recommends buying a larger frame product within your budget, unless you have a need to shoot VLOG short videos. If you simply like photography, it is enough for ordinary users to purchase a full-frame camera. There is no need to choose a medium-format camera. Finally, photography is very expensive, and you need to be cautious when you enter the pit. Don’t give up halfway after buying a camera.
