What is principle of a digital camera? How to choose right digital camera

Hi friends, welcome back to video production and today I'm going to share some knowledge about digital cameras with you. Since many of our friends shoot videos themselves, it's a little difficult to choose equipment at initial stage, so today we'll talk about digital cameras.

The reason it's called digital is because it's different from previous film cameras. The second meaning is real origin of its name due to way a digital camera works: Using an electronic sensor. convert optical image into an electronic data camera. Unlike film, image data is recorded by a chemical reaction.

Usually divided by use and habit, roughly divided into several. That is: SLR cameras, mirrorless cameras, compact cameras, telephoto lenses and home cameras.

Let's share details below using SLR as an example.

I don't know how many of you who watch know why SLR is called SLR? In fact, you may not believe it, but it's very simple: single-lens reflex camera is origin of SLR cameras. You feel incredible. But it does, and it's actually different from mirrorless cameras because mirrorless cameras can't reflect light.

The following well-known brands are currently on market: Canon, Sony, Nikon, Fuji, Pentax, etc.

1. Large and heavy, like Canon 5d4, it weighs about 2.5k

2. Various lenses can be interchanged, which is very convenient and conducive to shooting scene.

The most expensive thing about a DSLR isn't body, it's lens, but if you want to shoot better work, you need to buy more lenses, so "three generations of bad photography" really refers to that. investments are very large, and without a certain economic power they are really inaccessible. Since kits are usually provided with headers, that is, conventional connectors such as 24-105 are usually used.

Following our simple analysis above, how do we choose camera that suits us in our daily lives. Let's analyze it in detail.

Generally speaking, we only have two goals. The first is a hobby, photographing for pleasure, cultivating senses and recording life. The second is a guy who eats, takes photos and videos, carries a camera and a tripod with him, walking around every corner of city. This is most faithful image of our photographers. For former, entry-level is usually sufficient, but in fact, we will find that some grandfathers have more professional cameras than you. High-end cameras have multiple lenses on back. Here, if you are into this type of hobby. otherwise, please ignore my advice.

Many people struggle with this most: they listen to what others say and write online and then don't know which brand to choose. In fact, this question is very simple, just go directly to store to try it, you will know if you choose a specialty store, it will provide a free trial shot of prototype, which is very convenient. He said he lost his own opinion, and speaker spoke from his own point of view and point of view. For example, requirements for shooting video and photo are different. Many people have this experience. Canon photo is high quality, but Sony photo is high quality Video quality is good, so it depends you mostly use it.

If you have good economic conditions, you can buy a medium and high class car from very beginning. You don't need to start with an entry-level machine, because in end you will still focus on mid-range and high-end machines, and it is impossible to constantly use entry-level machines. For example, you can directly buy 6d or 5d series from Canon and price/performance ratio is quite good. Especially 6d, I think it's Canon's most economical machine.

If you're really on a budget, buy an entry-level Lianlian first and wait for technology to reach a certain level and cost-effectiveness to improve before upgrading to a mid-range and high-end machine.

Generally speaking, there are several parameters for choosing a camera, such as pixels, frame size, sensitivity range, latitude, etc. Of course, this should also be related to price, but these parameters are certainly important factors in determining photography quality.

Generally speaking, many people buy a stock camera for first time, for example: 24-105, focal length is large, and stock camera is relatively cheap, which is more profitable. It is also possible to have a separate lens. It depends on your usage.

Ok friends, above we will share with you our digital cameras and how to choose camera that suits you. I hope to be of some help to you and avoid detours. In end, I hope everyone can give a lot of likes and support!
