Comparison Nikon Z30 kit 16-50 vs Nikon Z50 kit 16-50

— USB C. A universal USB interface that uses a Type C connector. USB ports themselves (all types) are used mainly for connecting the camera to a computer for copying footage, managing settings, updating firmware, etc. Specifically The Type C connector is comparable in size to earlier miniUSB and microUSB, but has a reversible design that allows the plug to be inserted in either direction. In addition, USB C often operates according to the USB 3.1 standard, which allows for connection speeds of up to 10 Gbps - a useful feature when copying large amounts of content.

- HDMI. A comprehensive digital interface that allows you to transmit video (including high resolution) and audio (up to multi-channel) over a single cable. The presence of such a port makes it possible to use the camera as a player: it can be directly connected to a TV, monitor, projector, etc. and view your footage on the big screen. In this case, broadcast capabilities can include not only video playback, but also demonstration of captured photos in slide show mode. HDMI inputs are present in most modern video equipment, and connection is usually not a problem.
Nowadays, there are several versions of the HDMI interface on the market:

• v 1.4. The oldest version currently relevant, released in 2009. However, it supports 3D video, is capable of working with resolutions up to 4096x2160 at a speed of 24 fps, and in Full HD resolution the frame rate can reach 120...fps. In addition to the original v.1.4, there are also improved modifications - v.1.4a and v.1.4b; they are similar in basic capabilities, in both cases the improvements affected mainly work with 3D content.
• v2.0. Significant HDMI update introduced in 2013. In this version, the maximum frame rate in 4K has increased to 60 fps, and support for ultra-wide 21:9 format can also be mentioned. In update v.2.0a, HDR support was added to the interface capabilities; in v.2.0b this function was improved and expanded.
• v 2.1. Despite the similarity in name to v.2.0, this version, released in 2017, was a very large-scale update. In particular, it added support for 8K and even 10 K at speeds up to 120 fps, and also further expanded the capabilities for working with HDR. This version was released with its own cable - HDMI Ultra High Speed; all features of v.2.1 are available only when using cables of this standard, although basic functions can be used with simpler cords.

— Headphone output. Audio output allows you to connect headphones to the camera. As a rule, it is represented by a classic 3.5 mm mini-jack. The presence of such a connector provides the ability to monitor sound during video recording in real time. This is especially important when filming interviews, vlogs and other similar projects.

— Microphone input. Specialized input for connecting an external microphone to the camera. External microphones are significantly superior to built-in microphones in sound quality. Firstly, they are not so sensitive to the camera’s “own” sounds - from buttons, control wheels, focus motors, etc. (and if the microphone uses a long wire and is not attached to the body, these sounds will not be heard at all). Secondly, external microphones themselves have more advanced characteristics. On the other hand, their use is justified mainly for professional video recording; therefore, the presence of a microphone input, as a rule, corresponds to advanced video recording capabilities

The type of viewfinder provided in the design of the camera.

A viewfinder is an eyepiece in which the photographer is able to see the image being shot, and in some cases additional information (the location of autofocus sensors, individual shooting parameters, etc.). Regardless of the type, viewfinders are useful in that they allow you to clearly see the image you are shooting, even in bright ambient light (which can cause displays to “blind”). Their disadvantages are the need to bring the camera close to the face, as well as the inconvenience when working with glasses (although the latter is partly offset by diopter correction in the viewfinder itself). The types of viewfinders can be as follows:

— Electronic. Such a viewfinder is a system of lenses with a small screen behind them. It is widely used in advanced cameras with non-replaceable lenses (see "Camera Type"), can be used in MILC cameras, and relatively recently full-fledged " SLRs " have appeared (in particular, made according to the so-called "translucent mirror technology") equipped with electronic viewfinders. The advantage of such a viewfinder is that, in addition to the image itself, it can display a large amount of service information (for example, about shooting parameters); the main disadvantage is the need to supply power from the battery (although the power consumption of such a system is still much lower than that of an...external display).

— Optical. In this case, an optical viewfinder means an independent system with its own eyepiece and lens, built into the camera body and directed parallel to the optical axis of the lens (mirror and prism systems are separated into separate categories). Such a system can be located both directly above the lens and in the corner of the body. The advantages of optical viewfinders are simplicity, low cost and compactness, due to the absence of a complex system of mirrors or prisms in the design. Such a viewfinder can be used in any non-reflex cameras (classic digital or MILC). The main disadvantage of this option is the mismatch between the position of its lens and the main lens of the camera (the so-called parallax effect); in most cases, this does not create inconvenience, but when shooting at close distances, you have to take an amendment (although there are camera models with viewfinders that automatically correct).

— Optical and electronic. A specific type of viewfinder that combines elements of both systems described above. Usually, such structures are based on an optical viewfinder, which provides for the possibility of projecting various service information onto a visible image. And in some models, the system can also be switched to a fully electronic mode, blocking the access of light through the optics and observing only the picture on the screen through the viewfinder.

— Optical (mirror). As the name implies, the design of such a viewfinder is based on a system of mirrors. Through this system, the real image perceived by the camera lens is fed into the viewfinder eyepiece (in other words, the photographer is actually looking directly through the lens). SLR viewfinders are used exclusively in cameras of the corresponding type (see above). Their advantages are the absence of the parallax effect and the ability to immediately evaluate a number of shooting parameters, such as depth of field, the effect of installed light filters, etc. The main disadvantage of reflex viewfinders is the need to raise the mirror at the time of shooting. This complicates and increases the cost of the design, makes it less reliable, and the operation of the mirror lifting mechanism can cause vibrations and the “stirring” effect.

— Optical (pentaprism). In fact, it is a kind of mirror viewfinder (see above), in which the role of a part of the mirrors is assigned to a pentaprism — a glass structure of a special shape. The action of the pentaprism is based on the effect of the so-called total internal reflection; it is believed that in this way it is possible to achieve a brighter and clearer image than when using classic mirrors. Other advantages and disadvantages are identical to conventional reflex viewfinders (see above). The pentaprism is widely used in mirror devices.

— Is absent. The complete absence of a viewfinder in the design of the camera; For sighting in such models, a display is used. This feature is typical mainly for digital compacts (see "Type of camera"). Firstly, the dimensions of the body of such models often do not allow for a viewfinder to be included in the design; secondly, the specifics of the use of such cameras is usually such that the display is quite enough for them, and sometimes it is even more preferable — for example, when shooting from a non-standard position (above your head, with your arm outstretched in front of you, etc.).

This setting can be simplistically described as the amount of magnification provided by the viewfinder relative to how the image appears to the naked eye. The features of modern viewfinders are such that most of them have crop values less than 1 — that is, it somewhat reduces the visible “picture”.

In general, the larger this parameter, the larger the objects look in the viewfinder and the easier it is to focus through it.

The ratio, expressed as a percentage, between the portion of the image that the photographer sees in the viewfinder (see above) and the image that is actually captured by the camera when shooting. Most often, it is specified as a percentage of the width and height of the frame, rather than the area.

Modern digital cameras often have viewfinders with a frame coverage of less than 100% - thus, the frame includes not only the visible scene, but also some space beyond its edges. This creates some inconveniences - in particular, it may be necessary to crop the photo to ensure a pre-conceived composition. Therefore, a viewfinder with 100% coverage is still considered the ideal option. Some time ago, such systems were found mainly in premium cameras, but now, thanks to cheaper prices and technological developments, they can be installed even in relatively inexpensive amateur compacts (see "Product type").

Size of the camera's native display in diagonal inches. The larger the screen, the more convenient it is, usually, to use. In particular, a larger and more detailed image can be displayed on a large screen; in addition, size is of great importance for the ease of operation of the touch display (see touch screen). On the other hand, the dimensions of the display have a corresponding effect on the dimensions of the device. Therefore, screens of more than 3 "in modern cameras are quite rare.

USB C is the newest type of USB connector, with a small footprint and convenient reversible design. And Power Delivery support allows this connector to accept high power power, which helps quickly charge the camera battery.
