Digital Camera with video recording: the pros and cons, features, specifications

Digital cameras with recording Full HD capable to compete in amateur or semi-professional cameras. However, the video quality is dependent on a number of Performance - matrix size, the zoom optical stabilizer.

When choosing a camera, pay attention to the characteristics of the matrix, processor, lens, flash. The impact-resistant will be a welcome addition, and protects the unit from serious damage.

The acquisition device with the recording Full HD camcorder to replace completely or partially, depending on the destination of the product. If you plan to semi or professional photography, the preference better to give digital SLR models.

The principle of operation of the digital camera with video recording

Matrix, Photosensitive member, acting as a film - the main component of the camera from which the recording quality depends. It operates as follows: the object reflects light, which passes through the lens falls on the matrix and the light is converted into an electrical signal is then processed by the processor.

Resolution is measured in pixels matrices - the higher the number of pixels per inch, the sharper the image. In modern cameras, the following standard resolutions:

• HD - 720p (1280x720).
• Full HD - 1080p. (1920x1080)

In fact, Full HD is the same thing only with HD high resolution.

recording quality depends on the size of the matrix.

Dimensions measured in inches - the area 25 times smaller shooting frame area. The values ​​range from 1 / 3.6 "(4 mmh3mm) to 4/3" (18mmh13,5mm).

In digital SLR cameras the size of a matrix comparable with ½ frame area or the full-length.

According to the type of the matrix is ​​divided into:

• CCD (CCD) - high image quality with an average speed and large power inputs.
• CMOS - cost-effective, high-speed, with a better autofocus, but with a large image size and average quality.

Depending on the coverage you need to adjust the sensitivity of the array to the light - ISO. In bright illumination ISO values ​​are set low, under low, dim lighting conditions - high.

CPU The "brain" of the mechanism, controls the parameters and modes, using it and creates a file with a photo or video image. Monitors the status of the gate, adjusts the exposure, the amount of transmitted light and the aperture, the light intensity. When recording video in FULL HD camera processor compresses the video bitrate.

Lens - focus and forms an image on a matrix and includes a lens made of high quality optical glass.

The cameras are divided into two categories according to the type of lens:

• standard, where the focal length is static,
• zoom lenses where the focal length is changed.

Recent visually enlarge distant objects in detail (zoom):

• Digitally (software). Scale of the object, which affects the quality of the picture (can be compared with the increase of the image on the monitor).
• Optical. Works on the principle of a telescope, does not affect the image quality.

Zoom lens expressed in digital multiplicity: 2x-80 and higher optical zooms value rarely exceeds 30-fold - to record video FULL HD recommended 12 times. Devices with a high magnification lens have considerable size and equipped with optical image stabilization system.

image stabilizer There are two types:

• Optic. It is a movable lens, built-in lens.
• Electronic. Adjusts the image read from the matrix by changing the position of the camera.

Optical Stabilizer provides a better image, but makes noise during operation.

Display - visualizes images and allows you to control the recording. When you select a device should pay attention to screen size and resolution than the rates are higher, the better. Displays large-size, energy consumption, which affects the operating time of the camera.

Cameras with Video Full HD resolution of different quality, but they should only purchase in the case where the equipment, which will be able to view the video to support the format.

Remember: When shooting video in Full HD standard, quickly discharged battery, and runs out of space on the memory card.

Therefore, this technique is suitable for short stories, and videos for ordinary enough resolution 1280x720 (HD).

functions

Digital equipment is divided into two categories of cameras: digital and digital SLR - offered a record in high definition Full HD.

The standard parameters of digital SLR cameras include:

• The large size of the matrix (22mmh15ii), the output is a high-quality video and images,
• Powerful processor - the video at a speed of 60 frames / s,
• Quickly switch between modes (with photos to video and vice versa)
• Videozum removes moving objects in high quality,
• Manual exposure adjustment, aperture, lens,
• Dividing footage into fragments for further correcting and combining in one full roller,
• Lenses by application - wide angle, macro lens and a telephoto lens - shooting objects of any complexity, from insects to landscapes,
• Different types of flares let you experiment with lighting,
• Optical Stabilizer (not in all models) - the risk of blurred shots is minimized,
• Peripheral illumination correction (not all models)
• Support for multiple memory cards with individual slots,
• Interchangeable lenses, optional equipment connection,
• Change, update the camera firmware,
• Handheld is possible thanks to aperture lens and high-sensitivity matrix.

This is not a complete list of parameters and functions of digital cameras. Additional features include:

• Connecting to Wi-Fi to transfer the footage to a network,
• Ability to connect an external flash ( "hot shoe").
• Correction of photo and video camera with additional settings and software and bypass the connection to the PC.
• Easy setup allows comfortable with the device, even a novice.

Choosing a camera with recording Full HD, pay attention to the standard features and options, extra do not affect the recording quality. In addition to the basic, important indicators, not least take design features.

Design

Models with Full HD recording feature impact-resistant housing, less watertight. Cameras are equipped with special protective elements and matrix technologies to protect against dust and dirt.

The case itself is made of durable plastic or metal. Mirror device arrayed in a metal housing with a trim "the skin".

The cameras are built extra outputs to connect to third-party devaysa - HDMI, card slots. Displays are rotary or static depending on the model.

Buttons made at the control panel - control over camera operation. Sometimes part of the management put to the touchscreen display. When choosing a camera, pay attention to the management model, the speed of this transition depends on one mode to another.

Batteries, which are equipped with cameras, have a small capacity. They allow you to shoot up to 30 - 60 minutes, and this is without the use of additional features (high resolution video, display, etc). Therefore it is recommended to purchase additional high-capacity batteries.

Advantages and disadvantages of a camera with video recording

Plus Full HD shooting - is of high quality and resolution, which is easy to work in the future when processing footage. Shoot videos, short scenes or clips.

Images captured with the help of Full HD camera, obtained "live" and interesting, rather than footage of standard video camera.

Along with the advantages and disadvantages are present:

• With the device removed planned scene with uniform motion without abrupt movements. But vsporhnuvshuyu bird or fast-moving subjects difficult to remove even with professional features.
• To work in video mode have to resort to tripods and stands, otherwise the picture will turn out, "lubricated".
• Built-in battery for the video mode lasts for a limited amount of time. Therefore it is necessary to pay attention to the parameter "number of hours".
• The camera recording Full HD camcorder to replace, if you shoot a short time commercials, music videos. However, for complex scenes shot (over 15 min), the camcorder better fit.

device service life is extended due to normal usage. If a user violates them, this leads to breakdowns and requesting service.

Exploitation

Each model is equipped with a special case, necessary to protect the unit from dust, dirt and moisture. Keep the device in a case, or zeal and grit to score a lens that will lead to its failure.

Do not drop the camera, despite the shock-resistant case - sensitive elements of electronics and mechanics may be damaged by the shake-up.

If the body of the model waterproof, internal components are protected, nothing terrible will happen.

Time charge the battery. If this is the battery, then replace them with high-quality batteries.

For shooting in extreme conditions, it is recommended to purchase devices with integrated protection against external negative influences. They are shock-resistant, cold-resistant and waterproof.

malfunctions

Frequent breakdowns is considered a broken display or lens. The reason for this failure - the physical impact on the apparatus. Display Repair produce only master in the specialized service for repair of electronic and optical equipment.

The camera is not included due to moisture ingress. Remove the batteries, do not attempt to operate the unit and the more use of the flash. If the unit does not turn on after drying - there was corrosion in electronic units, it requires complete disassembly and cleaning in an ultrasonic bath and welds the contact groups.

Failure of the "hot shoe" connector is responsible for connecting an external flash. Repair if replacement parts made in the service center.

If the camera lens is not working correctly operate the zoom, poor focus, or lack thereof, of possible objects clogged by sand and other abrasive particles. It is necessary to blow compressed air - if the problem persists, it is required in the diagnosis of SC.

Breakdown elements without external causes (drop of water ingress, the sun heating) is a rare phenomenon.
