Interchangeable optics or non-replaceable?
Enough words have already been said about matrices and carcasses, now it’s time to talk about an equally important thing – the lens.
The lens is the main element of the camera, no matter how strange it sounds. The image quality by 90% depends on the lens, so it’s worth choosing the device responsibly.
We have already decided that a large matrix is good and a small matrix is bad. Now let’s decide on replaceable and non-replaceable optics. Everything is not so clear here.
As you know, SLRs and system cameras (mirrorless) involve the use of interchangeable optics. But there is another class of cameras on the market – these are “premium compacts”. Unlike ordinary soap dishes, they have 1-inch matrices, that is, they are comparable in size to “cropped” cameras. But unlike SLR and system cameras, these compacts have non-replaceable lenses – quite high-quality, but non-replaceable.
Why change the optics on the camera? Even if we superficially study the basics of composition in photography, we can find out that it is customary to photograph different scenes for better transmission in a photograph with different focal lengths. The focal length determines the latitude of the lens angle. The smaller it is, the wider the viewing angle. A wide-angle lens “moves away” objects, but allows you to place a fairly large sector of space in the frame. Accordingly, increasing the focal length gives the opposite effect – the viewing angle narrows, the fragment of space that came into view is “stretched” over the entire frame.
The above examples show the difference between a wide-angle picture and a telephoto lens. For the purity of the experiment, of course, it was worth shooting from one point, but I think the meaning is clear.
The photos above are two extremes. In everyday shooting, focal lengths are most often used, at which the perspective is close to what we see with our own eyes.
These two examples of photographs illustrate the most typical application of the camera for amateur purposes – to photograph landscapes and their friends and relatives (either at home or against the background of the same landscapes).
These photos are shown here for a reason. If you buy a camera with non-replaceable optics, most likely you will be limited by a range of focal lengths of 28-70 mm (maybe a little more, but not much). This camera will allow you to get very good quality photographs, but if you suddenly want to seriously take up landscape photography, then with this camera you will be confined to a wide angle limit – you cannot “push” the lens closer than 28 millimeters. The other extreme is photography hunting. Here you will already miss the “long” end and there is nothing to be done about it. Cameras with non-replaceable optics are good for walking lightly – they easily fit in the pocket of your jacket, allow you to take pictures of remarkable quality, but shooting atypical scenes will not be available to you.
If the camera involves the use of interchangeable optics, then all these restrictions are removed. Naturally, lenses cost money, sometimes a lot. But if you are a creative person, plan to learn, grow and develop, then I highly recommend purchasing a camera with interchangeable lenses. Even despite the fact that with a standard lens the picture quality can be inferior to premium compacts (and it will most likely be!), Such a camera even with a cheap fixed lens (no zoom) can leave a camera with non-replaceable optics far behind in terms of quality.
Mirror or mirrorless?
If you decide to purchase a camera with interchangeable lenses, you are faced with the next task – to choose the type of camera. The choice is small – either it is a SLR camera or a system camera (mirrorless). To get started, look at this picture:
This is a comparison of the size and weight of the mirrorless lens with the “top” standard lens and a mirror with a middle-class lens.
Currently, DSLRs and mirrorless ones are about the same extent popular, and the choice largely depends on your personal preferences. By and large, the presence or absence of a mirror in the design of the camera does not affect the quality of the resulting photographs. The filming process is slightly different.
When shooting with a SLR camera, we look into the optical viewfinder, which through a system of mirrors shows us the picture as it appears in the lens. For system cameras, a screen or electronic viewfinder is used for this, which shows us a picture in the form that the matrix “sees” it. Which is better – optical or electronic viewfinder? A definite answer cannot be given – and both have their own pros and cons.
