What distinguishes a good digital camera?
Image quality is the criterion against which cameras must be measured. Tests prove that a high image quality depends solely on the resolution of the image sensor. In addition to the sensor, the lens with its imaging performance has a significant influence on the quality of the photos, so test magazines evaluate Sensor and lens compact digital cameras as a single unit. Deliver the best image quality System and SLR cameras. No wonder: these cameras have on average the largest image converters. But you can also find models with good image quality among the compact cameras, which by name rely on particularly small case size and thus require small image sensors – especially with the noble compacts.
The operation of the camera is also included in the evaluation of the trade journals. The testers assess positively when the digital camera intuitive and simple operation. In addition, motif programs and automatics are put to the test, which helps beginners in particular to get good photos. A confusing menu, on the other hand, leads to the devaluation of the respective digital camera.
Especially for digital cameras in the upper price regions, the Speed and accuracy of autofocus a big role. Especially for SLR cameras and system cameras, the reliability of autofocus is a decisive criterion.
Smartphone or compact camera?
Smartphone cameras are getting better and so it is hardly surprising that fewer and fewer people are spending extra money on a Digicam. But even if the shots of smartphones and compacts hardly differ from each other, the compact cameras have a decisive advantage: they usually have a Zoom lens! Smartphone cameras, on the other hand, usually have only one lens with a fixed focal length and can only zoom digitally, which is equivalent to an image cut – and consequently a loss of quality.
For example, if you want to get details bigger on holiday, you’re better advised with a small digital camera with zoom than with your phone’s built-in camera. The smartphone manufacturers have now recognized this and are installing two cameras with lenses of different focal lengths in their more expensive models. However, the zoom that can be achieved with it does not completely convince testers and users. And for a real zoom lens, there is simply no space in the housing.
Which camera is the best for me?
Depending on the size, they already fit into the Shirt or jacket pockets, as a rule, however, the sensor is also small, which affects the quality of the recordings, especially in low light. If you are looking for a compact camera that great results even in low light you should make sure that they are connected to a 1-inch sensor equipped. This is used in so-called noble compact cameras and still provides beautiful photos even in the case of twilight. Cheap digicams for beginners under 200 euros, on the other hand, offer hardly any advantages over the cameras, which are installed in modern smartphones.
At first glance, bridge cameras can easily be confused with SLR cameras. They are large and grippy housing equipped and have an expansive Zoom lens. Often you also have an electronic viewfinder. However, you can save yourself the lens change with the bridge camera. Compared to SLR and system cameras, however, the sensor is significantly smaller for bridge cameras, which is a clear disadvantage in low light. Some bridge cameras offer a very high zoom factor – sometimes even above what professional lenses achieve on an SLR camera. In order to ensure that large focal lengths are shake-free recordings possible, it is important that the camera is connected to a powerful image stabilizer equipped. Since almost all cameras with a fixed lens have an image stabilizer, it is worth taking a closer look at the test results.
Digital cameras with the highest zoom factor
SLR and system cameras (abbreviated DSLR and DSLM)
It is not for nothing that most professional users use cameras with interchangeable lenses. Depending on the shooting situation, the best possible lens can be selected. In addition, these models are equipped with larger sensors than most cameras with integrated lenses. This not only increases the quality of the images but also makes it possible to low depth of fieldwork. A low depth of field ensures that you can sharpen a motif in front of a pleasantly blurred background that can highlight. This effect (bokeh) is now also known from smartphones, where it is digitally simulated. However, the harmonic effect of an SLR or system camera is usually not achieved.
Excursion: Finding the right lens when working with a system or SLR camera, it is important to choose the right lens. First, it must be connected to the camera, the so-called BayonetFit. Most manufacturers use their own systems and different bayonets for DSLRs and DSLMs. The next decisive criterion is the Focal length, which should be chosen differently per subject. Finally, the Number of apertures specified in each lens – the smaller the number, the larger the aperture and the better results you can in low light Achieve. Especially in low light, Image stabilization is helpful. It can be integrated either in the camera’s chassis or lens, preventing shaking during longer exposure times.
How many megapixels do I really need?
The table below gives you a rough guide to what resolution your digital camera should provide for viewing photos on the respective medium. As a result, 10 megapixels are sufficient for most purposes. However, the average resolution of digital cameras is now around 20 megapixels. The higher resolution offers the advantage that images Subsequently trimmed and there is still sufficient resolution. Professional photographers sometimes pick up professional system cameras with more than 30 megapixels back to have enough “reserves” when croe.

Why doesn’t my camera take good pictures in low light?
The belief that more megapixels equal better image quality is held up in the minds of many users. Of course, this is not entirely wrong, but small sensors with many pixels as found in compact cameras, they have difficulty delivering good images in low light. The reason: The pixels on the image sensor share the invading light. If many small pixels are crowded close to the sensor, very little light remains for each pixel to produce an electrical signal for the digital image. In addition, if the amount of light invading decreases, for example at dusk, the signal generated by the pixel is often not sufficient and must be amplified. With the reinforcement, the Noise which leads to a loss of detail. The photos don’t look as beautiful as in the sunshine.
Fewer pixels on the image sensor means that each pixel is larger and can collect more light. The noise is therefore lower. So if you want better image quality in low light, you would get a camera with a large sensor and few megapixels, for example, the System Camera Sony Alpha 7s. In the area of compact cameras, it is worth looking at the precious compacts.
