What is a DSLR camera?
The contrast to the analog SLR models is that there is no film inside the DSLR camera but a recording sensor. This has the advantage that the image material is immediately available digitally.
This makes it possible at any time to view erroneous or failed photographs and, if necessary; to repeat or correct them immediately. In the case of the DSLR camera, the picture quality and its size can be set directly at the camera and can be changed at any time.
Just like in the case of the analog SLR cameras; the lenses of the cameras can be changed at any time in the digital models. This allows for greater application possibilities. The finished images are stored in RAW format for most models.
All possible information about the pictures is available. Thus, in most models of the digital SLR cameras; an immediate post-processing of the images can take place.
In general, SLR cameras have the reputation of being a complex, difficult-to-use and expensive species. However, this is usually only imaginative people. This is why they often buy overpriced cameras; whose image quality is significantly lower than that of an SLR camera.
Here the SLR cameras are thanks to many automatics such as autofocus and the like autofocus In today’s time so easy to use. Just pushing through and pushing up is the motto.
Advantages of a DSLR Camera
Advantages of a Digital-SLR camera at a glance:
- With the interchangeable lenses, each DSLR camera must be adapted to the respective tasks
- The power consumption of the cameras is low
- Large image sensors ensure good image quality
- Since the image sensor does not heat up there is less picture noise
- Most models have a powerful autofocus
- The devices are robust and stable
- With the DSLR camera there are countless manual settings
- The display makes a good assessment of the quality of the pictures possible
- All recordings in the DSLR camera can be stored in the RAW data format; without any loss of information
- The fast sharpness detection allows higher speeds during photography.
With all their advantages, the DSLR cameras, whether digital or not; also have disadvantages, but they do not prevail.
Dis-advantages of a DSLR Camera
- Compared to compact digital cameras they are rather large
- Many different interchangeable lenses require a lot of space; and the whole camera becomes heavier
- The price is significantly higher compared to the compact cameras
- Deeper photography skills are required for manual adjustment
- Since the lenses have to be chosen appropriately for the camera and each manufacturer has only a certain contingent; the lens selection is restricted
- DSLR camera is sensitive to dust and dirt.
How to buy a DSLR Camera or What functions do I’ve to consider when purchasing a DSLR Camera?
Before buying a DSLR camera, hobby photographers should consider; whether they really need and use such a camera.
For occasional vacation snapshots, a small and lightweight compact camera is certainly better; than the larger and heavier DSLRs.
Ambitious hobby photographers and professionals certainly need a DSLR with all the chicanes. Although digital SLRs are also for beginners of photography, they are equipped with all possible automatic functions; but if you want to get excellent pictures, you should familiarize yourself with the manual functions of these cameras.
Always different settings and control elements lead to different results. Mirrorless system cameras are becoming more and more popular in the market. They are so popular because, despite their smaller size and lower weight; they make sharp, beautiful photographs.
Fast and Sharp Focus
DSLR camera focus more quickly and have a longer shutter lag, making them ideal for shooting moving subjects; such as playing children or performing sports events. The biggest difference between DSLM and DSLR cameras lies in the viewfinder.
This viewfinder allows a better view of the subject; with system cameras usually dispensing with this viewfinder. With these cameras you can see the picture only on the display; which is therefore somewhat cumbersome. For video recording, a system camera is a much better alternative.
Image sensor size, not megapixels, is what matters in DSLR Camera
The next thing to note is the sensor format. The larger the sensor, the better the quality of the finished image. Digital SLR cameras are clearly the front line, because the built-in chip of a compact camera can not keep up with that of the SLR camera.
The only problem with this, however, is that the larger the sensors are; the more expensive they become.
The most expensive models can be found at the full format sensor. In this range, the new models without lenses are only starting at around 8,000 AED and are open to the top.
For this, however, you will be rewarded with the sensor chip in the size of a 35mm negative film (24 x 36 millimeters) and thus; with good shots even in very poor viewing conditions.
In addition, the images of the large sensors are reproduced without loss of sharpness when printing – quite in contrast to images of a compact digital camera.
The sensor chips with APS-C format, which are only half as big and are used with most DSLR camera; offer great results at a reasonable price.
Do more Megapixels mean better photo quality?
The resolution is another point to note. Common DSLR cameras have a resolution of 18 and 24 megapixels. Even with lower pixel numbers, the photos, thanks to the better image sensors, are still sharp.
In the case of the DSLR camera, however, the reduced number of pixels is advantageous in the case of dim light conditions or in the dark; since the individual pixels are much larger on the image sensor.
If the ISO standard values are in the range of 100 to 1600, the Canon EOS 700D achieves an ISO value of up to 25600. With a higher ISO value; the exposure time can be reduced due to the low incidence of light.
However, with a rising ISO value, the image looks coarser; which is referred to as noise in jargon.
Choosing the Best DSLR Camera for Beginners
The next point should be the operation as well as the comfort, especially in beginners photography is important. Robustness as well as handiness is desired by the photographers and besides a good picture quality and the equipment; the ease of use is an important purchase criterion.
If the low-priced entry-level models are made of plastic; the professional equipment is made of magnesium. This magnesium is a durable material without too much weight. Good devices also have a seal against dirt; water and dust, the most common causes of a malfunction of the sensitive image sensor in the DSLR camera.
Also haptics and the shape of the camera are particularly noticed when buying. If it is well in the hand and the trigger is easy to reach; it has a rubber coating for improved handling of the grip surfaces, then the camera is already as good as bought.
In addition, the most important (or for you individually the most loved) functions should be adjusted by fast access.
What DSLR camera lenses do I need ?
The lens is an important and indispensable accessory. Often, these interchangeable lenses are just as expensive as the camera itself. Therefore, just beginners should consider exactly which lenses are needed.
For the zoom lenses, for example, the focal value is variable; while there are also lenses with a fixed focal length. Ideal are the kits offered by the manufacturers. These include favorable combinations with zoom lens and base for beginners.
For photographing in low light conditions, zoom lenses have not been effective because they are less light. These lenses, however, offer one great variability in motivation. Two lenses with different focal lengths are ideal for beginners.
Here, a lens with 24 to 70 mm and a second lens with a 70 to 200 mm focal length have proven their worth. If you do not need a telephoto zoom, you get three light-focussed lenses; with fixed focal values for the same money.
Beginners are well equipped with a simple telephoto lens; a macro lens and a wide-angle lens.
The choice of a suitable manufacturer of the DSLR camera is very important with regard to the lenses; because each manufacturer has its own lens connection. There are adapters that allow you to switch between them; but the focal range is changed.
The leading manufacturers Nikon and Canon offer the largest lens selection. Sigma and Tamron, third-party manufacturers, also manufacture lenses; that are cheaper but work less well and are compatible with Nikon and Cannon cameras.
The viewfinder and display offer clear advantages in a DSLR camera. Compared to system cameras you have a more realistic feeling for the subject. Good cameras have a viewfinder display in dioptre number, which is adjustable.
This is ideal for spectacle wearers. For most cameras, however; a 3-inch diagonal is used for the displays and the image resolution is high. If white pixels are also installed in the display; they can be recognized wonderfully in daylight.
Image quality is also an important buying criterion, if not the most important. This quality depends not only on the camera, but also on the lens.
The following criteria should be decisive when purchasing:
- A high degree of visual acuity, which is achieved by the lens and the image sensor alike – the highest possible sharpness allows even the finest structures to be seen in detail
- The value of the diaphragm gives information on the image of the subjects and their contrast – the largest possible number of aperture stages has a great influence and can represent the contrast correctly
- The color accuracy must be observed so that the motifs are reproduced as faithfully as possible on the picture – the data is given by the DeltaE value, which should be as low as possible
- The DeltaRGB = white balance is also important – the same as for color accuracy
- The noise occurring at higher ISO values – the noise also referred to as VN = “visual noise” should be as low as possible
- A noise reduction, which compensates for the noise of the picture – it can occur that motives with weak contrasts lose details – a “kurtosis measurement”, the result of which should be as low as possible.
Ultimately, it is up to you to decide what is important to you. For example; a high ISO value suggests Always down on the price. A good balance of the price-performance ratio is therefore advised.
Is optical image stabilization (OIS) a necessary feature for any lens?
Last, but not least, the image stabilizer, which is essential for wobbly, sharp images. This image stabilizer, built into the case or lens; should be of high quality when photographing by hand. The camera is kept steady during strong zooms and a longer exposure time.
This stabilizer causes the exposure time to be shortened as a function of the focal length; and at the same light conditions. This prevents or minimizes the shake of the resulting images. Images taken with a long exposure time require a tripod.
The gain of the image stabilizer is necessary for larger zooming options or larger focal lengths; but can be switched off for short focal lengths.
