The significance of SLR camera and the difference between micro-single camera (recommended by novice)
It is called a SLR because a plane mirror is placed obliquely inside the camera. When shooting, the reflector falls, reflecting the light entering from the lens to the pentaprism, and finally reaching the viewfinder after being refracted by the pentaprism. When shooting, the reflector is raised, and the light entering from the lens directly shines on the film or image sensor. Because the reflector and shutter are purely mechanical structures, the shutter speed and continuous shooting speed of SLR are limited. At present, the highest shutter speed of SLR is 1/8000 seconds, and the fastest continuous shooting speed of optical framing is about 16 frames per second.
Structural comparison between SLR and micro-single
However, the micro-single camera has no structure such as reflector and pentaprism. Behind the lens is an image sensor. Single camera uses LCD screen or electronic viewfinder to take pictures. Because there is no mechanical structure such as mirror, the micro single body can not only be made lighter, but also the upper limit of shutter speed and continuous shooting speed is higher. The continuous shooting speed of ordinary micro-sheets can reach 10 sheets per second, and the continuous shooting speed of flagship micro-sheets can reach 30 sheets per second.
In addition, the micro camera system, especially the Quan Huafu micro camera system, has the characteristics of large aperture and short back focal length, so it has higher flexibility in lens design. While achieving overall high image quality, the lens volume can also be well controlled.
Large aperture bayonet and short back focal length make lens design more possible.
After years of development, the performance configuration of micro single camera has been very powerful. Take EOS R5 of Canon Quan Huafu micro camera as an example. 45 million effective pixels, can shoot 8K video, continuous shooting speed up to 20 frames per second. Full-pixel dual-core focusing technology supports eye recognition and animal eye recognition. The camera body has anti-shake function, which can be linked with lens anti-shake and can achieve anti-shake up to 8 times. Because of the innate structure and late-comer advantage, the performance configuration of micro-single camera with the same price has surpassed that of SLR camera.
Quan Huafu Canon Micro R5 has extremely powerful performance configuration.
So is there really no need for SLR cameras to exist? In fact, compared with micro-single, SLR cameras also have their own advantages.
1. lens resources
In fact, for interchangeable lens cameras, the performance configuration of the fuselage is of course important, but what is more important is the matching lens resources. Compared with 13 micro camera, SLR camera has a much longer history and more lens resources to choose from. Although the lens resources of micro single camera can be called rich now, it is still far from the SLR with decades of history. In terms of SLR lenses, the original lenses of various brands are rich enough, and there are a large number of auxiliary lenses and classic old men to choose from. Canon and Nikon have dozens of lenses behind each SLR.
SLR lens resources are more abundant.
Because it is no longer the hottest product, the SLR lens of the same specification is much cheaper than the micro-single lens. For example: Nikon Gold Wide-angle AF-S 14-24 f/2.8G ED VR, the market price of brand-new products is about 8,000 yuan, and the second-hand lens with good color is only 5,000 yuan. The price of a micro single lens of the same specification is as high as 16000 yuan, and because it is a new product, there is almost no second-hand on the market. The price of Canon EF 50mm F 1.8 SLR lens is stable around 700 yuan all the year round, while the price of micro single lens with the same specification is around 1300 yuan.
As long as you don't plan to travel around the world with a mirror, you should consider the cost related to the lens. A little pursuit of Quan Huafu micro-single, and intend to get better shooting, then the budget will be doubled. What's more, many SLR bodies with outdated performance configurations are already very attractive. If you count the lens, the price advantage is very obvious.
Step 2 be patient
In the era of SLR, endurance is the last thing photographers care about, because even an entry-level SLR has at least 300-500 endurance. The mid-range SLR and above models have a battery life of almost 700, and the flagship model has reached a horrible battery life of several thousand.
The flagship SLR has a strong endurance.
Compared with micro single camera, it has no advantage in battery life. Even with large-capacity batteries, most micro cameras have a battery life of about 300 when fully charged. If it is a period of concentrated shooting, or if the machine is turned on and off frequently, the endurance will decline faster. The main reason for this situation is that the screen, sensor and other large power consumers have been working at full load during the use of the micro-camera.
Is SLR still worth buying now?
There are three brands still selling SLR, namely Canon, Nikon and Pentax. Because Pentax SLR system is relatively unpopular in China market, the scale is very small, so I will skip it here. Let's focus on Canon and Nikon.
Nikon z series miniature camera
Canon R series Quan Huafu microchip and M series APS-C microchip.
There is no doubt that Canon and Nikon R ampd and their production focus have shifted from SLR to micro-single, but this does not mean that these two companies will shelve or abandon the SLR product line in a short time. At least in the next three years, they may regularly launch entry-level SLR and Quan Huafu models for beginners of photography to meet the upgrading needs of old users. After all, the resources of SLR lenses and accessories are too huge and wasteful to use, and old users will not agree.
Quan Huafu SLR photographers will continue to update.
As for the flagship high-speed SLR with long life cycle like 1D X III and D6, it is really possible that it will be the last generation of products. After all, micro-cameras have advantages at high speed. At present, Canon R3, Sony A 1 and Nikon Z9 have completely surpassed the flagship SLR in high-speed shooting. Equipped with a full-size body, it can also be equipped with a larger capacity battery, and its endurance can be basically the same as that of a SLR.
The flagship high-speed SLR may not be updated.
For those who want to learn photography, if you are not sensitive to the size of the fuselage and the main purpose of buying equipment is to take pictures instead of videos, then a cheaper SLR with more lens resources is undoubtedly more suitable for you. At present, there are many cost-effective SLR cameras on the market, ranging from entry-level to Quan Huafu. You can choose the product that suits you according to your own needs. Moreover, compared with digital products such as mobile phones, the update speed of cameras is not long. It is not a problem to use a camera with mainstream performance for 7 or 8 years.
For you who are already SLR users, you don't have to worry about future equipment upgrades. Both Canon and Nikon may launch new SLR on a regular basis to meet the upgrading needs of old users. Moreover, even if you buy a new micro-single, the SLR lens in your hand can continue to play a role in the new machine through the adapter ring.
Will SLR disappear?
Last question: Will the single lens disappear? The answer is yes. After all, without the constraint of mechanical structure, the micro camera can achieve better performance and lighter volume. In terms of lens resources and endurance performance, major brands are also trying to make up for shortcomings. When the micro-camera is comparable to SLR in terms of body performance and accessories resources, there is really no need for SLR products to exist.
