Since the introduction of digital video formats, 2k digital cameras have been popular among photography and video enthusiasts. These cameras are capable of capturing still images and videos in 2k resolution. This is also considered to be the simplest format among the common digital formats that are specified according to horizontal resolution instead of the other existing formats such as 1080p which are in terms of vertical resolution. An image taken using a 2K digital camera is 2048 pixels wide.
What is 2K resolution?
When it comes to digital cinema standards, 2K is one of them. With 2,048 horizontal lines and normally with 1,556 vertical lines, the term 2K refers to the horizontal resolution in pixels. Digital cameras that are considered 2K are better than 1080p cameras because they contains more pixels with regard to horizontal resolution.
A camera with 2K resolution can take still images and videos at 2048 pixels. However, in terms of vertical resolutions, results may vary because of the different aspect rations. That is, a 2K image containing an HDTV aspect ratio has 2048 x 1152 pixels while one with an Academy ratio has 2048 x 1536 pixels.
This resolution is common in digital cameras and even 4K digital cinema resolutions are converted to 2K just so they can be accommodated in most digital theaters. Better than 1080p, a 2K video format with 2048 x 1080 is equivalent to 2,211,840 pixels. This manifests a difference of 138,240 pixels between a video format at 1080p and 2K.
When it comes to frame rates and resolutions, this video format is flexible. Both 1080p and standard 2K resolutions can record up to 30 fps. Other 2K digital cameras can capture slow motion shots of up to 72 fps in 720P mode. There are other features such as built-in wireless IP connectivity and file-sharing that makes it possible to edit using available software. Same as with other digital cameras, 2K cameras also have CMOS sensors.
One action camera that boasts of 2K resolution is the Xiaomi Yi which is an affordable camera from a Chinese camera manufacturer. Apart from the capability to shoot 2K video at 2304 x 129 pixels, it also sports a video processor which can be similar to GoPro. It also has 1 megapixel BSI and has WiFi and Bluetooth connectivity.
Sony also has its own model, the HDRAS20 2K Action Camera has an image stabilization system and also has a built-in WiFi connection for remote control. 2K cameras are usually lightweight and built for portability. They can also take still images at 12 MP.
