How to choose a SLR?

Question 1: How to choose a suitable SLR camera for beginners? First, let's take a look at what a SLR camera is.

SLR camera is short for SLR camera. Specifically, it is a camera that uses a lens to view through a mirror.

Therefore, this paper does not discuss cameras with two lenses and cameras that do not look through the mirror. The picture below shows the Great Wall double-reflex camera, Leica paraxial camera, Canon card camera and Sony micro-camera.

As shown in the above figure, although Sony a7 is much like a SLR camera, it is not a SLR camera because it does not reflect through the lens optical path.

What are the advantages of SLR cameras over other cameras?

First of all, what you see is what you get. Because you view directly through the lens, the image you see from the viewfinder is an image obtained as a result of shooting. Secondly, the response speed is fast. The start-up speed of digital SLR is only a few hundred milliseconds. Because their focusing systems are independent of imaging equipment, they can basically achieve the same response speed as traditional SLR, making users handy in news and sports photography.

Secondly, the lens selection is convenient. Each brand has a huge autofocus lens group, from super wide angle to super telephoto, from macro to soft focus. Users can choose matching lenses according to their own needs. The picture below shows Canon lens group and Nikon lens group.

Ok, let's introduce the general situation of SLR cameras at present.

At present, the mainstream SLR cameras are mainly 135 SLR and 120 SLR. 135 SLR includes all SLR cameras of Canon Nikon. At present, 120 SLR mainly includes mamia, Pentax and Hasselblad.

In which 135 SLR is divided into aps-c format SLR and Quan Huafu SLR.

For example, Canon 1200d, 100d, 700d, 750d, 760d, 70d, 80d and 7d2, Nikon d3300, d5300 and d7200 are all aps-c format SLR. The following picture shows Canon 760d, 700d,100d; ; Nikon d3300, d5200, d7200

Canon 6d, 5d3, 5ds, 5dsr, 1dx, 1dx2, Nikon d6 10, d750, d8 10, d4 and d5 belong to Quan Huafu SLR. The following picture shows Canon 6d, 5ds,1dx; ; Nikon d4s

Generally, SLR cameras and lenses have a general classification, such as entry-level or junior, intermediate, advanced and professional.

Entry-level: Canon xxxd, xxxxd, Nikon d5xxx, dxxx, featuring light weight, high degree of automation, certain professional functions and high cost performance. The picture below shows Canon 760d and 700d；; Nikon d3300, d5200

Intermediate: Canon xxd, Nikon d7xxx, dxx, the fuselage strength is significantly improved, the shutter usage is much higher than the entry level, and it has various professional functions. The picture below shows Canon 80d；; nikon d7200

Advanced: Canon xd, Nikon d7xx, D8x, general professional fuselage with aps frame, or Quan Huafu fuselage. The fuselage has high strength and various professional functions. The picture below shows Canon 5ds；; Nikon d8 10

Professional grade: Canon 1d series and Nikon dx series, suitable for harsh shooting environment, with extremely high durability and reliability and various professional functions. The picture below shows Canon1DX; ; Nikon d4s

120 SLR belongs to a special category, and it is discussed separately at last.

Ok, let's get down to business. How to choose a suitable SLR camera?

We generally analyze it from two angles, one is according to the purpose, and the other is according to the capital budget.

First of all, use is the purpose of buying a camera.

If there is no clear shooting purpose, it is a general photo shoot or a photo shoot while traveling, it is recommended to set up an entry-level machine.

For example, Canon xxxd+ 18-55 or xxxd+ 18- 135, Nikon d5xxx, DXXXX+18-55 or+105.

If you usually travel a lot, but are generally interested in photography, you need to record various scenes of your trip. It is suggested to consider a set of Canon xxxd+ 18-200 Nikon d5xxx, dxxx+ 18- 140 or 18-200 (if there is no such matching, you can purchase the matching body and lens separately. Of course, this combination is also suitable for friends who have just learned photography and have limited funds.

For ordinary photographers, Canon Nikon's mid-range camera is the first choice. This level of machine has various professional functions, and the price is relatively cheap, which not only has considerable durability and fuselage strength. You can take all kinds of photos that need special treatment ... >>

Question 2: How do novices choose a SLR to buy a camera "Canon or Nikon"? There are students who study photography, family users and photographers, some who want a card machine, and some who buy a SLR. Canon and Nikon are the best-selling photographic equipment products in China. Who is better? Can be considered from the following aspects.

1, Usage: Everyone has different preferences for photography, so you should have a positioning for your own use before buying a camera. For example, some like traveling and scenery photography; Some people like portraits and take pictures of their families. With positioning, let's talk about the following characteristics: Canon's tone is warmer, that is, the film will be red; Er Kang's tone is cold, and the film will be blue when it comes out. In other words, Nikon is more beautiful, and people who like to take portraits use Canon.

2, preferences: Canon's imaging soft point, Nikon's imaging sharp point. For example, taking portraits at the same time, Canon's facial skin may look smoother, and Nikon will take out spots and hair, depending on your own preferences. If you don't PS, it is estimated that many MMs can't accept Nikon's face, and what you may need is this sharpness of hair.

3, accessories (referring to SLR users): bought the fuselage without a lens can not be used. Nikon has been an expert in optical products for many years, and the price of lenses is relatively cheap (excluding five new lenses scraped from June 5438 +2007 10); Canon has high-tech product technology, and the L-head is an indispensable weapon for professional photography now, and the price is of course very high.

4. Surrounding environment (referring to SLR users): Now the price of SLR is very low, and ordinary users can afford it. Unless you are a professional photographer, if ordinary consumers mostly borrow some lenses and equipment from each other for fun. Because some of Nikon's equipment is not compatible with Canon's, it is sometimes convenient to consider what machines friends borrow from each other. However, there is a saying in the industry for super enthusiasts and professional users (wives and equipment are not allowed to borrow).

5. Cost performance: Nikon and Canon are both old brands of digital SLR, and the current market price is very transparent. It makes sense that you get what you get at a price. According to personal economic ability, we should believe that market time is a test of quality. Just like a digital SLR put into the market, after a period of market test, some will fall and some will be firm, which can also prove some truth.

Which is better? Love is blind. Only what suits you is good (don't listen to people). Friends who choose the machine can choose from the above points. As for which is better, Nikon or Canon, people all over the world have discussed it for decades, but there is still no result. There is no result now, and I hope there will be no result in the future. The two major manufacturers are confronting each other, benefiting our consumers. Quote a classic sentence between photographers: "If Canon and Nikon don't know how to choose, flip a coin!" ! Whichever you buy, you will like it! "

In fact, Nikon and Canon are both very good brands. It should be said that Nikon's main products are concentrated in the field of SLR, while Canon is omnipotent and has strong competitiveness in both home and SLR. In the field of SLR, it should be said that Nikon and Canon have their own characteristics as a whole, but Pk Canon has obvious technical advantages between the same machine emperors. Canon has its own entire industrial chain and intellectual property rights, while Nikon cannot fully grasp all industrial chains. Classified, Canon is the best image processor, and digi 3 processor has no rival at present. The new 1ds mark iii sensor has now reached the full size of 2000w pixels, and the lenses have different lengths, and the basic process is close.

Generally speaking, it is generally believed that the top SLR is better than Canon. Mid-range products have their own advantages, and Nikon is more cost-effective. The low end is similar. Generally speaking, the choice of SLR should be made between the two. There is no third option. You should choose the best Canon, otherwise Nikon is also a good choice. However, it is difficult for SLR to enter the second one, because the lens determines the high cost of changing doors. Be careful.

As far as home computers are concerned, I think Nikon Canon is good, but Nikon doesn't seem to attach much importance to home computers and has fewer series. Most people like to choose Sony, but people who know how to do things generally don't choose Sony, because the best ccd quality is Fuji's super ccd, and the shooting quality and corresponding speed largely depend on the processing chip and related software. From the image processor alone, Canon's image processor digicii/... > >

Question 3: How do novices choose SLR camera lenses? It is recommended that novices buy a large zoom lens ~ ~ that is, a mirror that can let you use it for a long time.

It is recommended to buy the original factory. Although the vice factory is cheap, the color difference is far away.

Nikon and Canon's 18-200 is very easy to use, over 4k, with anti-shake.

Wait until you have a fever. . . Consider buying some other lenses. In this case of large zoom, buy a fixed focus and super wide angle at most, and the economy allows a macro and fisheye, which is invincible. (except for those with high quality requirements. . . )

The camera lens has been connected upstairs. But the distribution of shops in each place will be different. Those are not provided by manufacturers, but by merchants themselves, and some of them are also very affordable.

Question 4: How should a novice buy a SLR? First of all, we need to recognize some common misunderstandings in purchasing SLR. Common misunderstandings for beginners to buy SLR Misunderstanding 1: You have to buy Canon and Nikon to buy SLR, which is professional enough. Answer: 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. Answer: If you have carefully studied the configuration of SLR, you will find a problem. Most of the reasons that make SLR more expensive are not because of the improvement of imaging quality, but because of more things such as anti-shake of fuselage, CCD dust removal, or the use of 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. Answer: 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. Answer: This is a fact. We should all know that the imaging quality of any SLR equipped with headgear can basically surpass that of the flagship consumer 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.

Question 5: How to buy a SLR body? What are the important parameters? If you have enough money, go to the full-width D700 and 5D2 at the price of 14000.

Half width is divided into entry-level machine and intermediate machine. Take Nikon as an example, D300s and D7000 are intermediate, and D5 100 and D3 100 are entry-level.

Advantages of mid-range SLR:

1. The pentaprism viewfinder (with a pentaprism at the lower end) has larger magnification and brighter viewfinder.

2. There is a shoulder screen at the middle end, so you don't need to look at the LCD screen, and the parameters can be adjusted professionally and quickly.

3. Mid-range fuselage double thumbwheel (Nikon), with adjustable aperture and shutter.

4. The mid-range machine has many focusing points, fast focusing, accurate metering and is not easy to run out of focus.

5. Mid-range shutter time is shorter (support 1/8000), and continuous shooting speed is faster.

6. The mid-range has a strong sense of height, with a general low sense 100 and a high sense of 3200 available.

Please feel free to ask questions about the choice of brand and model. Good luck with everything.

Question 6: How to buy a SLR camera and what parameters should I pay attention to? It is enough to buy Nikon D90 at home. The head of 18- 105 is now around 5500. If there are not enough people, you can upgrade to 18-200.

If the budget is enough, you can directly buy Nikon D7000+ 18-200 sets of machines and travel around the world in one shot. About 10 thousand,

Or Nikon D600, but the head will choose a lower one, Quan Huafu;

There is also Nikon's new D710018-105 machine set, which is also within 10,000. I'm not sure about the specific parameters, you can check them.

Canon's mid-range machine can be sold for 60d or 7D, but I personally don't recommend buying 7d, which is almost less than that in Quan Huafu. It's better to go directly to 5Dmake2.

Nikon's scenery is sharp in color, while Canon's is softer. Choose according to your own use.

Question 7: How to choose a suitable SLR camera? The camera is not cost-effective, only a penny is available. If you really want to pursue cost performance, you can buy a new product or a second-hand camera. The basic knowledge of photography can be learned from textbooks. Teaching in New York Institute of Photography is an international authoritative textbook. It is sold on Taobao. What can I see when I teach you photography?

There are a lot of professional knowledge and excellent photographers' works in photography websites like Hummingbird. You can go to the forum to dive and see the price of SLR. There is nothing to buy, and you lose. The problem is to choose the one that suits you. If you don't have strong financial strength, you can buy an entry-level SLR or a second-hand SLR.

Question 8: How to choose the lens of SLR camera? The question you asked is really a beginner, so I don't suggest you invest too much in the camera now, because you haven't figured out what you need and what suits you.

The division of lens focal length: first, the meter head-the so-called standard lens. Its viewing angle is about 43 degrees, and the viewing angle of the photo is closest to the human eye. Different frames have different title focal lengths. The standard lens of 135 film is about 50mm, the focal length of 6×6 title of 120 is about 80mm, and the title of 300d is about 50 ÷1.5 = 33 mm. Documentary photos faithfully record what you see with the title, so most documentary photographers like to use the title.

When the focal length is smaller than the pan/tilt, the lens can record images with a larger angle of view, so it is called a wide-angle lens. The shorter the focal length, the larger the viewing angle. The perspective of wide-angle lens is exaggerated, especially in landscape photography, more photos with visual impact can be obtained.

A lens whose focal length is 1.5 ~ 4 times larger than that of the meter head is called medium focus. Generally, the medium focus lens has the smallest deformation, and it is relatively easy to design it into a super-large aperture, so portrait photography is what the medium focus lens is best at. Generally, the focal length of the title is 1.5 ~ 2 times, which is used to take photos of the whole body and chest circumference. Shots larger than 2 times are mostly used for close-ups, and several shots called "portrait king" in the shot all appear in this focal part.

A lens that is more than twice the focal length of the head is called a telescope head. As the name implies, the telescopic lens can achieve "telescopic" shooting, which is mostly used to shoot sports, animals and so on. The application of telescope lens in scenery film can compress the far and near perspective of the scene.

Most people agree that Nikon imaging is sharp and suitable for landscape, while Canon imaging is soft and suitable for portrait and post-processing.

15-70mm camera covers the commonly used wide-angle and portrait focal length, but it does not mean that it can only be used to shoot wide-angle and portraits. For example, some people just take portraits with wide-angle lenses, but they get very special effects.

However, it is recommended that beginners play with headphones before considering buying more lenses, and then you will know more about what you need. The real master thinks about how to shoot with his own lens, not what lens to change. The head behind the camera is far more important than the lens.

Question 9: As a beginner in photography, how to choose SLR camera 1 and budget?

Budget is the first factor in choosing a camera ... because you can't buy anything without money. ...

Seriously, many people don't have a budget when choosing a camera. They went to the store and were told twice that they bought an expensive equipment, but they didn't necessarily buy the equipment that suited them. Store sales will be vigorously promoted because of the high commission of a certain brand, and consumers will often be misled to buy expensive and inappropriate equipment under such promotion means. As a result, an advanced SLR was used twice after being bought home, and then it was put in the cupboard and never used again. So, make a budget for yourself and choose the most suitable equipment in the budget. Budget has little to do with photo quality. Most of us are not billionaires, so it is impossible to buy the best equipment indefinitely, and the best equipment is not necessarily the best for us. Within the budget, do what you can. If the budget is insufficient, consider second-hand or previous-generation equipment.

At present, the upgrading speed of photographic equipment is too fast. As long as a digital camera is properly maintained, it can be used for three to five years or even longer. There is no need to worry that buying the previous generation of equipment will affect the quality of photos. In photography, the fuselage is often worthless, and only high-quality optical lenses can stand the test of time. So, if you choose a interchangeable mirror camera as your camera, I suggest you keep a part of your budget on the lens. Using the previous generation model will make your photos have better quality.

2. Decide your own investment in photography.

When choosing equipment, I often ask them whether to buy a camera to learn photography or take pictures of life. There are many ways to learn photography. Some people will seriously go to the studio to light up and shoot models at high speed. Some people just learn a little fur and share it online, so they enjoy being praised. There may be great differences in equipment selection between two different photographic mentalities.

For ordinary users who take photos of their lives, the card machine and even the iPhone are already the most suitable devices. What they need is a portable automatic exposure photography tool, which can be easily uploaded to the network without a lot of post-production. Recently, Casio's "* * * artifact" is so expensive, only because of the built-in beauty filter. In photographic equipment, such a * * * camera is actually only worth a few thousand dollars, which can be fried to a sky-high price. The big reason is that ordinary consumers will not spend time studying how photography skills can make photos better, but only hope that the equipment in their hands can provide the best photos in the simplest way. This is why we can still find the automatic mode on some high-end equipment.

As for some friends who are interested in learning photography, a camera in manual mode is the most basic requirement. Up to now, more than 98% of my photos are taken in manual mode, but now most advanced digital cameras have four exposure modes of APSM. Semi-automatic and manual exposure modes give the photographer more control over the camera and make it easier to achieve the desired effect.

3. Decide on the subject to shoot.

The subject matter of shooting has a great influence on the choice of equipment. Life photos, street snapshots, landscapes, commodities, portraits, sports, ecology, artistic creation ... Different themes have different requirements for equipment. The most widely used camera for photographing objects is a single mirror reflector. In most cases, SLR can meet the needs of the subject for photographic equipment. However, the size and weight of SLR are not acceptable to everyone. In view of this, the rise of mirrorless cameras has gradually replaced the low-end SLR market in recent years. However, the mirrorless camera is still a new camera type in the market, and the excellent lenses supporting automatic exposure and focusing are still limited. In addition, there is still a big gap between operability and SLR, so SLR is still the mainstream choice for photographers who shoot a wide range of subjects.

For the camera body selection of shooting theme, more consumers just want to take photos of life, travel and snapshots. For this kind of users, I suggest choosing a light camera. Users who have slight requirements for image quality can consider high-end consumer products and m43 systems. Compared with the general SLR, the portable design makes users more interested in using the camera. The higher the camera attendance, the higher the chance of taking good photos.

4, shooting format

The format here refers to the type of camera photosensitive element. There are many kinds of cameras now, which are below 135 frames and are divided into two categories: digital and film. Digital and film are two completely different imaging media, one is photoelectric signal transmission, the other is chemical action, digital is analog signal, linear exposure is nonlinear, adjustable or not, noise is particles, you can check the contrast system ... There is a fundamental difference between them, although it is convenient ... > >
