SLR CAMERAS ARE REMAINING A SAFE BET FOR EXCELLENT IMAGE QUALITY. WHETHER IN HIGH OR LOW BRIGHTNESS, WITH A FIXED OR MOVING OBJECT, NEAR OR FAR, A SLR CAMERA IS ALWAYS ABLE TO TAKE THE PHOTO YOU EXPECTED. THE SLR CAMERA IS EVOLVING BOTH IN CONFIGURATION AND ACCESSORIES.
Do you want your photos to have a unique hue? There are numerous filters to create effects or give your image a particular look. SLRs offer images a maximum of detail, whatever the conditions of their capture. You can review an image with photo software without risking losing quality. As you can see, a SLR has an incredible technological advance that stands out from compacts and smartphones!
Since all optical information revolves around the sensor, it is a key part of SLRs. Another is the processor, which composes the image.
The two types of sensors in SLR cameras are the 24 x 36mm Full Frame, and the APS-C which measures 14.9 x 22.3mm for Canon or 15.6 x 23.5mm for Nikon, Sony and Pentax.
Full Frame sensors are found in professional cameras like the Canon 6D Mark II, 5D Mark IV, Nikon D750, and Nikon D850. Cameras for amateurs and experts are equipped with APS-C sensors such as the Canon 2000D, Canon 80D, Nikon D3400, Nikon D7500 and Sony A77 II.
The type of photo to be taken determines the choice of sensor. For a studio or fashion photographer taking publicity or portrait shots, a full-frame sensor provides highly detailed images and makes it easy to manipulate the background focus to highlight the subject. For a sports or animal photographer, the 1.6 (Canon) or 1.5 (Nikon, Sony and Pentax) multiplier APS-C sensor allows you to adjust the frame to a distant subject. For fans or experts in animal or sports photography, we recommend the Nikon D500 or the Canon 7D Mark II: two SLR cameras adapted for these types of photos with excellent responsiveness and fast and precise auto focus.
Photography enthusiasts often start with a camera equipped with an APS-C sensor. SLR cameras like the Canon 2000D or the Nikon D3400 are suitable for those who want to take beautiful photos, although the technique scares them. These cameras are equipped with various scene modes to take a beautiful photo by simply selecting the correct mode.
Each SLR camera is equipped with a processor: Nikon’s Expeed, Canon’s Digic, Sony’s Bionz Z … The processor is responsible for retrieving the information sent by the sensor and converting it into an image.
As well as taking care of eliminating chromatic aberrations or reducing digital noise, it also ensures camera reactivity and manages auto focus and burst activation.
The Nikon D7500 is equipped with the latest generation Expeed 5 processor. The motion sensor and processor are wonderful both in terms of their responsiveness and image management. Photos have a high level of detail, even in difficult lighting conditions.
There are two types of viewfinders for SLRs: Penta mirror and Penta prisms. The amateur range is equipped with the penta mirror viewfinder and the pro range with the Penta prisms viewfinder.
The Penta mirror viewfinder consists of a set of mirrors that does not completely cover the field of view. Its magnification ranges from 0.8 to 0.85 x.
The Penta prisma viewfinder is a glass optical prism with a magnification between 0.90 and 0.96x. Although it weighs more and is more expensive to manufacture, it benefits from better gloss and offers larger image coverage.
Reflex cameras such as the Canon 800D and Nikon D5300 are equipped with Penta-mirror viewfinders that cover 95% of the field of view, and have a magnification of 0.82 x. In contrast, SLR cameras like the Canon 80D and the Nikon D7500 have Penta prisma viewfinders that cover approximately 100% of the field of view. The 80D and D7500 magnifications are 0.95x and 0.94x respectively. The professional range has more comfortable and brighter viewers than the amateur range.
Sony SLR cameras differ somewhat from those of other brands that include an interchangeable optical viewfinder. Sony equips its SLRs with electronic viewfinders just like hybrids: the small screens that show the image as it is when recorded, which is saved to the memory card.
An electronic viewfinder has a certain advantage over the optical viewfinder: each of its settings is visible in the viewfinder. On the other hand, the high definition and good fluidity of the viewfinder impact its usability.
The screen serves as a viewfinder on SLR cameras, as the image appears on it. The screen can be used for both photos and videos, and can be fixed, tilt or rotate, as well as touch.
The rotatable screen allows any viewing angle to be achieved. It is possible to photograph or record within a crowd, perform counter dives by placing the camera underground or turning the screen towards you; especially recommended for You tubers.
The DSLR’s touch screen works like that of a Smartphone, and is very useful when selecting the sharpness of the subject and taking the photo with one finger. The Canon 200D and Nikon D5600 are equipped with adjustable touch screens so you can adjust the focus of your photo. In video mode, it allows you to easily go from a sharp shot to a blurred shot and vice versa.
THE SCENE MODE:
Most cameras have multiple automatic modes: portrait, landscape, sport, night, etc. These modes help a lot in improving the quality of photos for beginners and those who have no interest in learning the basics of photography. Although you can use a SLR camera without having technical knowledge, the automatic modes are limited. It is impossible to obtain the same result as a professional photographer by simply pressing a button, as several parameters have to be taken into account, such as optics, settings, light, etc. The first ranges of SLR cameras like the Canon 2000D or the Nikon D3400 have more scene modes.
Professional SLR cameras have the privilege of having manual settings, unlike amateur cameras which are usually equipped with only one wheel. One of the wheels adjusts the diaphragm or aperture while the other adjusts the speed: it is much easier to make adjustments with these two wheels. The cameras also incorporate a small screen at the top to view the settings.
The 77D is Canon’s first DSLR equipped with two wheels and a small screen for viewing settings. It is a relatively light camera with all the settings.
RAW AND JPEG:
SLR files can be saved in two formats: RAW and JPEG. The JPEG is a compressed image and therefore the file loses information. Like any compressed file, some data disappears so that the image is lighter and takes up less space on the memory card.
On the contrary, RAW is a file without compression and therefore without data loss. Because it weighs more, it takes up much more space on a memory card. Also, you cannot leave a RAW file as is: it requires the development of specific software.
Each SLR is capable of processing these two types of files. In fact, you can choose JPEG for immediate photos and RAW for post-processing. Both formats can be recorded simultaneously in order to get an image quickly, and enhance it later.
THE VIDEO MODE:
They can be used with SLR cameras to record videos, since their image quality is superior to that of the traditional camcorder (Full HD and Ultra HD). Its wide range of optics, low-light performance and well-controlled depth of field offer excellent perspectives for video graphers.
The Nikon D7500 enables Ultra HD (3840 x 2160) video to be made at 24.25 or 30 frames per second and also records in Full HD (1920 x 1080) at 24, 25, 30, 50 or 60 frames per second. MOV and MP4 formats can be used, in addition to any manual settings.
