How to Choose a SLR Camera Misunderstandings and Points for Attention in SLR Camera Purchase

SLR refers to a single-lens reflex camera. The obvious difference is that the lens can be replaced and an external flash is connected. It's much bigger than a card machine. SLR is only one kind of camera, but because of its outstanding advantages, it has been adopted by many manufacturers and is more popular. Therefore, the configuration of this camera is better, and the lens can be changed, while meeting the needs of general users and professional photographers. So, how to choose a SLR camera? What are the misunderstandings and precautions in the purchase of SLR cameras? Let's take a look with Bian Xiao.

How to choose a SLR camera

Now there are two camps in the field of digital cameras. One is Canon Nikon, which makes its own lenses. They make the lens and then make the camera. One is that Sony and Samsung are famous for their electronic products. They use their own advantages in electronic technology and the lenses of other famous factories to produce cameras. Let's take a concrete look at how to choose a SLR camera:

1, buy a machine, first determine the price you can accept, which is more purposeful.

Low-end entry-level digital SLR packages (D60, 400D, K 100D, etc.) below 5,000 yuan. )

5000-8000 yuan low-end entry-level or advanced digital SLR body (450D, D80, etc. )+Another popular shot.

8000- 10000 yuan low-end digital SLR body+another large aperture zoom lens.

10000- 15000 yuan mid-range digital SLR body+with large aperture zoom lens.

The range of 15000 yuan is very wide, so I won't discuss it in detail.

2. Brand selection

In fact, many novices have no so-called brand preference, and they actually don't know which brand is better. However, some buyers have used some brands of digital cameras themselves, and feel that the brands they are used to will be better. Although this idea can narrow your choice a lot, it may also miss the excellent models of other brands. When choosing, you should abandon brand preference, accept other brands and choose the car that suits you best.

3, metering and exposure

In this regard, although there are some "selling points" differences in technical details, it can be considered that there is no difference in essence and there is no need to delve into it.

4. Focusing speed, shutter lag and continuous shooting speed.

These indicators are very important for news photography, sports photography, wildlife photography and snapshot photography. For digital SLR cameras, the improvement of performance is accompanied by a sharp increase in price.

5. Shutter life

The shutter life of general SLR cameras is 50,000 times, the life of high-end SLR cameras can reach 8-65438+ 10,000 times, and the longest life of professional SLR cameras can reach more than10.5 million times. In actual use, if the high-speed continuous shooting function is often used, the shutter life will be reduced. (The service life of LCD screen is about 1000 hours. Reflective framing system is a component that affects the life of digital SLR cameras. Frequent and high-load use can easily lead to the failure of reflective frame system. )

6, fuselage reliability

Advanced cameras are dustproof and waterproof, and can resist impact. Because of the metal body and special materials, the price of such a camera will be high.

7. Color space

In addition to sRGB as the standard color space for Windows and inkjet printers, you can also choose to use more widely AdobeRGB. You can choose the best color space according to the purpose of photography.

8. Flash system

For professional photographers, flash metering and exposure system is very important. Each manufacturer has its own unique skills in the automation of flash system, and there is no best or worst, only the most suitable.

9. Lens group

The advantage of a digital SLR camera is that the lens can be changed. Whether the original lens series support and the products of independent lens manufacturers are rich enough to meet your needs is a problem worthy of attention.

When you buy a digital SLR for the first time, if your purchasing power is low, you can buy fewer lenses. If your friends who play photography around you use the same brand of digital SLR as you, then lens intercommunication becomes possible. For example, all the friends around Mr. B use Nikon digital SLR. After Mr. B bought Nikon D80 sets, he could exchange lenses with his friends, which virtually increased the number of lenses that Mr. B could use. Moreover, all your friends use the same brand of digital SLR as you, and you can learn a lot from them, which will naturally speed up the progress.

10. Do you support W/A read-write acceleration technology?

All digital SLR cameras released after the fall of 2003 will support W/A reading and writing acceleration technology. With this technology, the reading and writing speed of TF card can reach more than 40 times (25MB/S).

1 1, transmission interface

Digital SLR cameras released after the fall of 2003 should have both USB2.0 and 1394 firewire terminals. Some cameras should also support wireless network transmission such as 802. 1 1b/g and Bluetooth.

12, photosensitive sensitivity and noise suppression

Higher sensitivity and better noise suppression are what we are pursuing.

13, shutter

The highest shutter speed and the slowest shutter speed (B door) are two key indexes of digital SLR camera shutter. The reliability and accuracy of the shutter also need attention. The highest flash synchronization speed is also a sign to measure whether a digital SLR camera is advanced or not.

14, handle, shape, weight

Whether the fuselage design is suitable or not is often the most important place to decide to buy a SLR camera. Regardless of the price, the size and weight of professional digital SLR cameras are not acceptable to everyone. Small and lightweight amateur digital SLR cameras are more suitable for ordinary people.

15. Is dust removal simple and convenient?

It is also a headache for digital SLR users. Because the digital SLR can change the lens, it also causes dust to easily enter the interior of the fuselage and fall on the photosensitive element, which will have a certain impact on imaging. In the past, the problem could only be solved by manual dust removal, but now with the help of the automatic dust removal function of the fuselage. As early as 2004, Olympus E-300 has been equipped with ultrasonic dust removal system. Today, Olympus ultrasonic dust removal system is still one of the most effective dust removal systems. Now the new models on the market have been equipped with dust removal function of the fuselage. Having said that, there are still many differences in the dust removal effects of various brands, and even the best dust removal system is difficult to compare with the manual dust removal effect in the United States.

Misunderstanding of SLR camera purchase

Misunderstanding 1. If you buy a SLR, you have to buy Canon and Nikon, which is professional enough.

Don't be confused by the words of some so-called senior SLR users, and don't be confused by N/C fans. Now the situation of SLR market has entered the era of war, and the era when Canon and Nikon monopolized the market is gone forever. It is true that if you "unfortunately" own some old lenses of Canon and Nikon, it is understandable to choose these two SLR, but as a novice without lens resources, choosing a SLR with the highest cost performance is the wisest choice.

Myth 2: People with cheap bodies and expensive lenses are "idiots", and a good head must be matched with a good body.

If you carefully study the configuration of SLR, you will find a problem. Most of the reasons that make the SLR expensive are not because the imaging quality has been greatly improved, but because there are more things like anti-shake of the fuselage, CCD dust removal, or metal fuselage. In fact, what really makes the SLR image quality different is the size of the photosensitive element. Therefore, if you don't have enough money to buy a Quan Huafu SLR and pay great attention to the picture quality, you should honestly buy a cheaper SLR with better lens.

Myth 3: SLR lens resources of other brands except Canon Nikon are too scarce. What if I buy a fuselage without a lens?

In fact, the lack of lens resources is only relative. Canon and Nikon's accumulated huge lens groups really make other brands of SLR unforgettable, but this does not mean that other brands of SLR lenses are not enough, especially novices. This problem is even more negligible. Moreover, the huge lens resources have also brought a side effect to Canon and Nikon, that is, the anti-shake lens with good imaging quality is expensive because the fuselage has no anti-shake function (the imaging quality of some cheap anti-shake heads can be known after use), so it is obviously impossible for Canon and Nikon with such huge anti-shake lens resources to add anti-shake function to the fuselage and make their anti-shake lenses waste. In the long run, fuselage anti-shake is the general trend.

Myth 4: The head of SLR is rubbish, so it is wise to match a good lens.

We should all know the fact that the imaging quality of any SLR equipped with a head cover can basically exceed the flagship consumer-grade DC. In fact, the front of the car is enough for beginners to practice their hands. Only when you have very high requirements for image quality, or have special shooting needs, is it time for you to consider abandoning the front of the car and starting other shooting.

Precautions:

The CCD/CMOS chip of digital SLR camera is easy to be contaminated with dust.

If the pursuit of image quality, choose100000 pixels above the SLR is enough. Look at the size of the photoreceptor and learn some late skills when choosing.

Buying a SLR, the lens is not a small capital investment, but also the gameplay point of the camera. When choosing a SLR, you should have a certain understanding of the lens parameters and applications, and don't waste money.
