The Sony NEX-FS100 is skilled video camera that is a game changer for corporate and event video producers. Standard specialist camcorders use three comparatively little CCD or CMOS sensors – one particular for red, blue, and green. This was fine for SD video acquisition but with HD video production, a tiny 1/three” or 1/two sensor is also tiny for suitable HD acquisition.
In order to acquire an HD image, makers resorted to a combination of smaller photo websites on the sensors and interpolation. Each of these techniques result in a noisy image, which is difficult for the video camera’s video codec. This left a lot of space for improvements and it was a Canon photo DSLR that solved the issue – the Canon 5D MKII. It featured a complete frame 35mm sensor and recorded HD video with a shallow depth of field, which is the capacity for a camera to have the subject in concentrate and the fore- and background out of concentrate. This is also identified as bokeh or defocus and is only possible with a large sensor.
Canon released two additional video capable DSLRs, the Canon 7D and 60D, but all three have been limited by short 12 minute record times and the absence of specialist audio inputs. In spite of this, several professional video production companies created the switch to DSLRs for video production as the advantages of a greater quality image and shallow depth of field have been deemed much more essential than the audio or record time limitations.
In order to compete against Canon’s 3 video DSLRs (and to a lesser extent, the Panasonic GH2 DSLR), Panasonic and Sony both announced video camera bodies with huge sensors that utilised SLR lenses. The Panasonic AG-AF100 was released in late 2010 and the Sony NEX-FS100 in 2011. Though not as big as the full frame 5D sensor, the AF100’s four/3″ sensor and the FS100 Super35mm sensor have been similar in size to the sensors on the 7D and 60D and were capable to create pictures with a shallow depth of field.
What made the massive sensor video cameras different from their DSLR cousins is that the sensors were not SLR sensors with a native resolution amongst 10-21 megapixels but rather big video sensors with a resolution slightly above HD video, which is 1920×1080, or 2 megapixels. Getting a massive sensor with a reduce resolution indicates that the video image is not sampled, like it is on the DSLR, which outcomes in false detail and video artifacts like moiré and aliasing. There is basically too a lot date on the DSLR sensors and the most dramatic instance is on the 5D, which is only in a position to approach 1/three of the data and throw’s out the rest.
The other advantage that big sensor video cameras have over DSLRs is that they have record times that are only limited by the storage capacity of the memory cards and they have professional XLR audio connectors. The Sony NEX-FS100 is confident to be a best decision for major video production firms as conventional camcorders and DSLRs are too a lot of a compromise.
