Choose your vlog camera the few things to check

The devices shown above tempt you, but you do not know which one is right for you? No problems, find below the list of questions to ask you to optimize your investment while producing quality vlogs!
What is your project ?
Videographers doing critical reviews of the latest box office movies do not have the same hardware needs as hiking fans who discover the most beautiful corners of a country. The first will focus on the quality of the sound return and the image in the lighted studio, the others will focus on the lightness of the device and perhaps the various options of stabilization of the image, for example.

So, before you even start browsing hardware catalogs, take the time to set the most recurring shooting conditions for your vlog project: will you still be indoors, or on the contrary, outdoors? What is the brightness of your location? Will you be mobile or will you go to your audience always face camera? Depending on your answers, some technical criteria of your future camera will hold your attention more than others, when choosing.

HD? Full HD? 4K? sony vlogging camera
Your project will allow you to evaluate the degree of definition of the image you need. The unit of measurement is the pixel. To put it simply, the more pixels you have in an image, the more it will appear on the screen. You will find below the number of pixels according to the different names of the so-called "high definition" formats:

- HD (high definition or 720p): 1,280 pixels per line × 720 lines

Full HD (1080p or 1080i): 1,920 × 1,080, or about 2 million pixels per image.

- UHD (or ultra-high definition, in 16/9 screen orientation): 3,840 × 2,160, which is 4 times more pixels than in Full HD.

- 4K: 4,096 × 2,160, a little more than UHD, but with a cinema format. Thin black bands will appear at the top and bottom of the image.

Many will tend to say that the higher the definition is initially, the more the image will be clear allowing a qualitative final rendering. But, is it really necessary for a youtubous beauty to film in 4K, and thus give the opportunity to each spectator to count the pores of his nose? Also, keep in mind that a movie shot in 4K is not only greedy storage space, but will also require a much more powerful computer and a recent editing software for editing your videos. These settings can weigh heavily on your initial budget.
Size matters ... for the sensor
The size of the sensor is crucial in your choice, perhaps more than the definition. Indeed, the larger the sensor, the more it is able to store light and therefore, the more the image is likely to be bright, even if the place in which you turn is not particularly. Attention: this size is expressed in millimeters or fraction of inches, according to the manufacturers. For example, a 1 / 2.5-inch sensor is smaller than a 1 / 1.6-inch sensor and a 24 × 36-mm sensor is larger than an APS-C sensor.

Focal and zoom
Are you going to shoot great landscapes or the details of your porcelain collection? Your answer to this question will determine the desired focal length for your future device. Focal is the "angle of vision" of your device. It is expressed in millimeters. The smaller the focal length, the wider the angle of view, the larger the number, the narrower the plane. Thus, a focal length of 24 mm allows you to make wide shots and film the floral park or the whole family at the wedding of your cousin in one take, without moving. Conversely, a focal length of 100mm or more will allow you to highlight the fine cracks of this painting by Monet, even if you are 3m from the board.

We have presented in this review compact digital devices, so the goal is not changeable. All are equipped with a lens with variable focus, that is to say, a lens that offers the ability to make camera zooms. In addition to the magnification capability of the image, check the following two data before you make your purchase:

Choose an optical zoom and not a digital zoom. The digital zoom magnifies part of the image while keeping the initial definition of the image, unlike the optical zoom, which brings the captured subject closer by moving the lenses of the lens. At equivalent magnification, the optical zoom maintains an optimal definition of the details of the image unlike the digital zoom, which may appear more pixelated.
The more powerful the zoom, the more the camera's stabilizer should be, so you can easily frame your image and avoid unwanted motion blur effects.
Depth of field: open your diaphragm
Complementary to the focal length, the aperture value of the diaphragm (expressed by the sign f / followed by encrypted values) allows you to evaluate the capabilities of your camera to restore the depth of field of the scene filmed (or more simply, the blur effect behind the framed subject).

When the diaphragm is wide open (f = 1.4, a lot of light enters the lens), the depth of field is reduced. This makes it possible to isolate a net subject in an environment, during a portrait or a macro shot for example. Conversely, a very closed diaphragm (f = 32, little light enters the lens) increases the depth of field, useful to integrate an action or a character in a setting, or capture a landscape in its entirety.
What about sound?
Although the devices on offer are all equipped with audio sensors, they may not be enough to get a quality sound mix for your vlog, especially if you have positioned your device in autofocus mode, or if you turn on outside. The ability to connect an external microphone to your device (as the YI 4K + allows) can be a decisive detail for the success of your future videos. Remember this adage of vloggers: the audience easily forgives the poor quality of the image, but not that of sound.

An adjustable screen to control your shooting
If you plan to make videos in front of a camera, a swiveling screen will prove to be a considerable asset to control what is happening on the screen during the shooting, without moving from your chair. With a 180 ° orientation, the Sony RX100 IV and Canon G7X Mark II cameras are excellent students on this criterion of choice. This will save you the time lost when you take out your shots to eliminate all those where you were out of the field.

Small details on connectivity and connectivity
These small details can quickly become necessities when you use your camera to shoot videos.

Connectivity side, check the compatibility of your device with a wide choice of SD cards on the market (like the YI 4K +) Discover here the best micro SD cards. This will prevent you from interrupting your shooting in 4K every 10 minutes due to an undersized memory card. An HDMI port is required to connect to your choice, an external hard drive to store your files, a monitor screen to control the quality of the image if your camera does not have an adjustable screen or an external microphone, if your case does not have a specific output for the latter. Make sure that this output does not apply data compression, to preserve the quality of the image as much as possible before editing.

On the connectivity side, more and more cameras integrate a Wi-Fi connection or NFC technology, to couple your smartphone to your camera and turn it into a remote control for example. The Nikon Coolpix A900 is a good example of connectivity by bringing Wi-Fi, low-power Bluetooth, and Snapbridge functionality into one box. About these technologies, check on the packaging the uses recommended by the manufacturers. For some devices, Wi-Fi only serves as a facilitator for transferring data from the camera to your computer, while others allow you to browse the web directly from your camera.
