Now 4K has reached the mainsteam everyone can experience the pleasure of Ultra HD vision at an affordable price.
4K cameras are among the popular camcorders in the market today and can range from DSLRs to production cameras used for films. These cameras have the capabilities of taking still images as well as capturing videos with what is known as 4K technology. The minimum resolution for a 4K camera is 3,840 x 2160 pixels and with an industry standard resolution of 4096 x 2160 pixels which is at 1.9:1 aspect ratio.
4K cameras are such because of its video format in terms of horizontal resolution which is 4096 wide. It is important to note that 4k cameras have both a maximum still shot resolution as well as maximum video resolution. The standard 4K Ultra HD video has a maximum video resolution of 3,840 x 2,160. As for the photo resolution, it can either be measured in megapixels or vertical and horizontal resolution, Having said this, a certain 4K camera can have a maximum photo resolution of 4608 x 345 pixels or 17.2 megapixels.
Conversely, for the type of processor used, these 4k digicams sport powerful internal processors. As for lenses, some 4k cameras do not come with the lens, there is a myriad of lenses available that are compatible with the lens mount. These lenses can impact the photo and video results. Sensor type and size of 4k cameras vary but the bigger the sensor is, the user can expect better images and footages. DSLRs usually have smaller and weaker sensors as opposed to video production cameras. As for video formats, 4K cameras can shoot in RAW but there are also some models that do not have this capability. Some can also shoot at 60fps although some cannot shoot 4K videos at 30 fps.
When it comes to ISO settings that deal with light sensitivity, there are 4K digital models that can have as high more than 400,000 ISO and can have as low as 50. Moreover, these cameras also use video technology and results can differ depending on the model and features of the digital camera used. Some DSLRs with 4K video capabilities can capture sequence still shots even at high speeds. This is due to the reason that 4K videos can have resolutions of 8.5 megapixels.
There are two 4K resolution standards: the DCI and the UHD-1. The former has a resolution of 4096 x 2160 pixels and used in video production and the film industy while the latter is also referred to as ultra high definition television which is now used in for television viewing. Basically, the DCI 4K standard is twice as the horizontal and vertical resolution of the DCI standard of 2K and the UHD-1 has twice the horizontal and vertical resolution of 1080p.
4K cameras can be DSLRs,hybrid camera and production cameras. Some of these are the Sony NEX-FS700R Super 35 Camcorder, RED Scarlet X, JVC GY-HMQ10 camcorder, Panasonic Lumix DMC-GH4 4K Mirrorless Micro Four Thirds Digital Camera, Panasonic Lumix DMC-GH4 4K Mirrorless Micro Four Thirds Digital Camera and GoPRO HERO4 Black, among others.
In conclusion, 4K cameras will remain to be a favorite of professional photographers and videographers as well as consumers who love to capture clearer videos and still images. Although there are still DSLRs and cameras in Full HD 1080p, 4K cameras will continue to dominate the market because of their features and capabilities.
