How to distinguish the good and bad of SLR cameras?

1. When choosing a SLR camera, don't focus on the pixel problem, because the pixel does not play a big role in the SLR camera, the main consideration is the size of the image sensor, the larger the image sensor, the larger the light receiving surface, so that the best effect is very good. The image sensor with a small photosensitive area will shoot very poorly, so be sure to consider the size of the sensor. However, there are other modes that can assist in shooting what is needed for the effect.

It is best to look for cameras where the shooting mode will be more.

Second, there are only a few brands of SLR cameras, if you plan to buy a SLR camera, as long as you find your favorite brand, consider the advantages and disadvantages of this camera. This makes it possible to pick a good DSLR camera.

Third, different models are compared**, the same model is compared to the size, if these two are the same, it depends on the actual ** of the camera, but if you don't understand this thing at all, it is very difficult to compare, generally speaking, depending on the style and color you like the camera, there are still differences between the ** of several major camera manufacturers on the market, but this is a matter of personal preference, not a quality problem.

Let's briefly talk about the parameters, the general camera has pixels, optical zoom, digital zoom, photosensitive area (divided into CCD and CMOS imaging), macro The size and pixels of the LCD screen, and whether it is a touch screen, whether there is optical image stabilization or electronic anti-image.

If you like to go out and play, it should be convenient and easy to use, with enough power, and good.

If you like to photograph people, you should take good portraits.

If you like shows, you want a DSLR.

In short, it depends on what you value.

There is no good or bad camera, it depends on your personal needs, what function you need, how many pixels, what type. I choose it according to my personal preferences.

What kind of brand is on the market, and it depends on whether you want to buy digital or SLR?

As long as it's a big brand, it depends on your requirements, it doesn't matter if it's good or bad, it depends on what features you want and what price you want.

First: Look at the sign.

Second: find anti-counterfeiting.

Third: look at the pixels.

Fourth: Shoot yourself for testing.

1. It should be from the perspective of your needs, these four machines are not strictly professional-level products, among which the 7D high-speed continuous shooting function may be aimed at the strong professional point, and the other three are entry-level and intermediate-level SLR cameras, so if it is a hobby, from the perspective of demand, these four machines are very suitable.

D entry-level, the most cost-effective, compared with the entry-level, mid-to-high-end 60D and 70D and 7D, to me the biggest feeling, or its continuous shooting speed and focus ability upgrade, these two points may be the main difference with the entry-level, but generally have little impact on shooting, in most cases can basically be competent. The 70D is an upgraded version of the 60D, which has been greatly improved in pixels and focusing system, which is also an important indicator of the performance of the SLR, and has also added functions such as WiFi for convenient transmission. So in terms of performance, the improvement in the performance of the mid-range flagship is still obvious, and if the consumption is set in the mid-range model, then the 70D should be an important consideration and selection object.

Finally, I want to say that whether the cost performance is high or not, it is still from the perspective of your needs, if it is a hobby, family shooting, and starting to learn, the entry level must be the most cost-effective. If you have higher requirements for performance, more demanding on process quality, and consider the selection of more lenses and accessories in the future, and there is no absolute demand for pixel size, then it may be more appropriate to choose a mid-to-high-end SLR camera. In addition, I want to say that after excluding the best factors, the higher the positioning of the product, the stronger the natural performance, and the more conducive to the development of the photographer's technology.

The size of the camera's light-sensitive element, the DU image processing chip, the focus system, and the support for the own lens group.

Dao hold, the material, weight, feel, accessories, etc. of the machine are more important.

DSLR Lens Basics:

1.Lens Attributes: Usually indicates whether the lens is an AF mount or an EF mount, and usually includes some identification of the lens category.

2.Focal Length Parameter: Indicates the focal length range of the lens, in mm.

3.Aperture Parameter: Indicates the maximum aperture factor of the lens, and some lenses also indicate the minimum aperture factor of the lens.

4.Characteristics: Indicates the characteristic technology used in the lens, etc.

1. Sensitivity (i.e., ISO), the larger the value range, the better, but it is best to combine the sample to see the noise at high sensitivity.

Whether the special point is too much.

Genus many. 2. The size of the image sensor is generally APS-C (Nikon called DX) and full-width (Nikon called FX) as the mainstream. The APS format is half of the full frame, and the image quality is better in full frame.

3. The focus module can generally see the number of focus points. The more focus points in general, the more cross points in particular, the better.

4. Shooting mode, the fewer preset modes and the more custom parameters, the more professional (of course, the more complicated it is to get started).

You can decide to buy it according to your needs (generally shooting and playing, or have creative needs, or want to shoot under special conditions). But for a DSLR, the lens is actually more important than the body.

In addition to the image quality, the SLR also depends on the control, the better the machine, the better the control, the more convenient it is to set the parameters, the more detailed, the focus, even shooting and so on.

So, depending on what you ask, the cost performance is not very easy to say, if you shoot generally, the entry machine will do.

If you want to talk about affordability, the 650D will do.

The size of the sensor area The grade of the lens The size of the aperture The advanced nature of the circuit Brand.

focus control, etc.

The Canon 70D is a mid-grade SLR, the latest and the best. You can take a look at the introduction of the major **. Launched in September.

The area and quality of the sensor are the most important, followed by the processing chip, which is related to the distortion of light and color, and the same is true of the lens. Then there's the handling. The cost performance cannot be compared, 650D is an entry-level machine, and 60D and 70D are mid-range machines.

A DSLR is a single-lens reflective mirror view camera.

The difference between a DSLR and a normal camera: appearance; SLRs tend to be larger, and regular cameras are smaller. Function; SLR is more complicated for people who don't know, pay attention to aperture, sensitivity, shutter speed, etc.

Shot; The ** of SLR shooting can have depth, depth of field, and good color effect. You can shoot some of the effects you want. The ** shot by an ordinary camera is more flat.

Whether a DSLR is good or not depends on your use value and situation. Take Canon, for example; If you compare the price to the bad, it is: 1D, 5D, 6D, 7D, etc., but they have their own characteristics.

In the end, the SLR wants the lens. Take Canon as an example, there is a red circle in front of the lens, this lens is better, and Canon's red circle lenses are all professional-grade. Ordinary lenses are all silver-circled.

SLR cameras depend on whether the lens is good or not, and the ordinary ones are too different

The two conditions that a DSLR has are:

1.It is framed with the structure of a mirror.

2.It can change the lens.

Those that do not have the above two conditions cannot be called SLR cameras.

Judging whether a DSLR camera is good or not mainly depends on its image sensor size, body workmanship and materials, shutter speed, picture noise control, picture tolerance, color shift, etc.
