Want to learn professional photography with a DSLR camera but don’t know how to choose? So please refer to 8 Tips For Buying A DSLR Camera in the article below. We will help you with more information when choosing to buy a DSLR camera.
Does the number of Megapixel dots affect image quality?
Camera manufacturers often advertise Megapixels for their DSRL cameras and make us think that a camera with higher dots is better. This is not entirely true, the high number of dots helps to enlarge the image without being broken, and the higher the number of dots, the larger the image can be enlarged.
However, taking good quality photos depends on many factors such as sensor size, lens, focus ability, … and the photographer’s technique. Currently, most DSLR cameras have a resolution of 13 Megapixels or more with this level you can print photos on a 33 x 48 cm photo frame, and even onto a 40 x 60 cm frame.
The large resolution makes the photos larger and you need a higher-capacity memory card to store them. Too high a resolution can also slow down the burst rate because the buffer fills up too quickly.
Sensor size when buying DSLR camera
The sensor is a very important factor when choosing to buy a DSLR camera. As you know, the camera has a large sensor and receives a lot of light, so the photos will be more beautiful and clear. On the market today, there are two types of sensors used, CCD and CMOS, CCD has better quality, but CMOS is more widely used because it saves battery and the quality is close to CCD.
Sensor sizes on DSLR cameras are mostly used in three sizes: Full Frame, APS-C, and Four-Thirds. The type of machine that uses a large Full Frame sensor usually has a large viewfinder, taking better photos in low light conditions. However, this type of sensor is quite large, expensive, and difficult to use for those who have little photography experience.
The most commonly used APS-C type is smaller than Full Frame and must replace lenses to get the wide angle desired. The advantage of this type of sensor is that it is cheaper, and the kit lens that comes with the APS-C camera gives a zoom range enough to satisfy most users.
The Four-Thirds used by Olympus and Panasonic required a completely new lens system. This type of sensor is smaller, so the cameras are also more compact than the APS-C type, although the image quality is not as good as APS-C when shooting in low light, but most basic users will not see the difference.
Should only buy the body (body) or buy with the lens?
If you are serious about becoming a professional photographer, you should purchase a camera body as well as additional lenses for various purposes such as portraits, landscapes, and motion capture. When the proper lens is used, the photo will look much better.
Some cameras include a multi-purpose lens with the camera, and the shooting quality is quite good, but the shutter speed is slow, and the camera cannot capture movement in low light conditions without the assistance of a flash. This is the next element in 8 Tips For Buying A DSLR Camera.
Shutter speed and autofocus (AF)
The faster shutter speed and focus speed of higher-end DSRL cameras. When shooting motion, such as sports or wildlife, this is critical. Most basic DSLRs can shoot at 2.5-3 frames per second (fps), which is sufficient for capturing motion, such as children or pets. Mid-range DSLRs can achieve 5 frames per second, while high-end cameras can achieve 12 frames per second or more.
When selecting a DSLR camera, autofocus is also crucial. The more focus points there are, the more the camera can detect the in-focus specimen in multiple locations throughout the frame. Apart from having multiple focus points, the faster the focus speed, the better.
To test the shutter speed and focus speed, try it out at a store, compare it to others, and prioritize choosing the camera with the fastest shutter speed and ability to focus.
To avoid blurry in images taken in challenging conditions such as low light, high-speed telephoto shooting, and so on, the camera or lens must have a good anti-shake system. Anti-shake is classified into two types: anti-shake by moving the sensor in the camera body and anti-shake by moving small elements inside the lens.
Although the anti-shake effects of the two are similar, sensor vibration is preferred because it is built into the device and works with any lens. Meanwhile, lens vibration necessitates the integration of this system into each tube, increasing the cost.
Lens shake is less popular, but it has the advantage of being reflected in the viewfinder. Sensor shake is used by Sony, Pentax, and Olympus, while lens shake is used by Canon, Nikon, and Panasonic. This is the next element in 8 Tips For Buying A DSLR Camera.
Machine size and strength
DSLR cameras are now available in a variety of sizes, ranging from small travel cameras to large D3s models. If you frequently shoot in harsh conditions such as high dust and humidity, you should select cameras that can operate in a variety of weather conditions, have magnesium alloy bodies, and have a system to remove dust from the sensor ( dust removal).
Generally, the larger and heavier the machine, the longer it will last. If you need to move a lot, choose a device that weighs about 0.5 kg and does not have a lens. Depending on the purpose of use, you select the appropriate camera size; the compact machine is easier to transport, but the image quality and durability are inferior to the large one. This is the next element in 8 Tips For Buying A DSLR Camera.
DSLR cameras can record HD movies, though not as well as professional camcorders, the video quality is excellent. If you want to record video with your DSLR camera, you’ll need a memory card with a large capacity and a fast reading speed.
Memory card speed is measured in Class; the higher the Class, the faster the recording speed; to record high-speed video (e.g., 720p at 120 fps), you must use a Class 4 or 6 memory card or higher. This is the next element in 8 Tips For Buying A DSLR Camera.
The cost of a DSLR camera
Prices for DSRL cameras range from a few million to 100 million. Cameras priced around 25 million VND are suitable for those who are new to photography; these models are simple to use, have good image quality, and include automatic and manual modes for you to practice your shooting skills.
Furthermore, interchangeable lenses and accessories can be used to improve image quality when necessary. When upgrading your camera to a higher model from the same manufacturer, you can still use this lens and accessory.
