We recommend a card player that can capture the effect of depth of field

Depth of field depends on the following physical conditions:

1.the size of the image sensor; The larger the area, the shallower and noticeable the depth of field.

2.focal length; The greater the focal length, the more pronounced the depth of field.

3.the distance between the subject being photographed and the camera; The closer you get, the more pronounced the depth of field becomes.

4.Aperture (engraved on the lens, marked by the symbol f); The wider the aperture, the more pronounced the depth of field is, for example, more pronounced than f/11. Note: The smaller the f number, the larger the aperture.

If you only choose a card machine, the above conditions will be used. In general card machines, the difference between the size of the image sensor is not obvious, so it can only be decided on the lens, and pay attention to the aperture and focal length of the lens. By analogy, the larger the lens with optical zoom (7x instead of 3x, 20x is ideal), the better the desired result.

After all, the effect and quality of the SLR can be shot, even if it is from the previous generations, is much better than the latest card machine! After all, it's a penny, a penny. However, based on the limitations of the budget, you can consider the previous two generations, the same model series of SLRs.

Olympus' e400 is a good example; No, just find a second-hand one.

Card machines are basically impossible; Shallow depth of field is not a feature that merchants can add if they want to.

Panasonic LX3,Aperture,It's good,Now the entry SLR is not expensive.,Buy a cheap body.,Add a large-aperture header.,Four or five thousand can do it.。

Try to find a large aperture with a large aperture, and the lens of the card machine also has parameters.

There are several ways to do this.

1. Ultra-wide-angle lens, the widest lens of the current card machine seems to be 24mm, and the scenery has a certain visual impact.

Second, with a panoramic function of the card machine, the typical is the use of Sony back-illuminated CMOS card machine, Sony in the past two years of models with "X" card machine such as wx5, tx5 or something, Canon this year's mid-range card machine also fully uses Sony back-illuminated CMOS, in addition, Fuji, Nikon, or what's new models are also mostly with panoramic function.

Third, if the camera does not have a panoramic function, you can also pan the camera to shoot a group of ** continuously, and then use processing software such as PTGUI to synthesize panoramic photos.

Whether it is in-machine synthesis or post-synthesis, proficient operation can improve the success rate.

Take a few pictures of them in different positions, and then make a splic.

I've studied this problem, and if you don't do post-production, there's only one way, open macro mode to get close to the object, so that the background has a lot of depth of field, and so far the only way I know of it.

It seems that the lens of the card machine is very small, but the aperture can be reached, because the actual focal length of the lens is very short, only a small clear aperture can be reached, because the CCD area of the card machine is very small, so the focal length of the shorter lens can get a relatively large angle of view (that is, the focal length is equivalent to 35mm).

Even if the aperture used by the card machine is used, it will not have a good depth of field effect, because the focal length of the lens is only about 5mm at this time, and the general 3x zoom telephoto end is only more than 10mm, and the aperture is only at this time, so the depth of field at the telephoto end is still not good (except for the macro mode, the shallow depth of field effect cannot be shot).

Lenses with different focal lengths, to achieve the same aperture value, the size of the aperture of the aperture is not the same, the shorter the focal length of the lens, the smaller the aperture, the longer the focal length of the lens aperture also needs to be larger, the f value is the ratio of the focal length to the aperture diameter, so it is very difficult for the telephoto lens to make a large aperture, the general small DC can do it, but it is very difficult to do it for professional lenses above 300mm, and the general zoom lens is also the maximum aperture of the telephoto end to be smaller. It is very difficult to achieve a professional lens of 300mm or more, and the maximum aperture of the telephoto end is also a small one for general zoom lenses. It seems that the lens of the card machine is very small, but the aperture can be reached, because the actual focal length of the lens is very short, only a small clear aperture can be reached, because the CCD area of the card machine is very small, so the focal length of the shorter lens can get a relatively large angle of view (that is, the focal length is equivalent to 35mm).

It is very difficult to achieve a professional lens of 300mm or more, and the maximum aperture of the telephoto end is also a small one for general zoom lenses.

It should cover more than 80% of the cameras on the market with this feature. Sony's is the most numerous and the best to use. In addition, each detailed model is listed in descending order of time of market availability and attention, and some older models may no longer be available.

Hope it helps.

I won't get this either, so it's better for you to check it yourself on the Internet! For example, Zhongguancun** and the like.

If it weren't for taking hundreds of shots every time**, I personally think that Sony's at the same price is better, but the battery life is slightly poor, and it is difficult to match the domestic substitute battery, Canon does not say that the battery life is strong, but it is easy to match the substitute battery. The rest is just a ** problem, pay attention to the choice of optical image stabilization.

I'm using Sony W390, 14.1 million pixels, G lens, large aperture, 24mm ultra wide angle, 5x optical zoom, with optical image stabilization, large screen. **1669 yuan with gifts. W350 parameters and W390 are about the same,**1399 with gifts。

Both of these are cost-effective card machines. It is recommended that you go to Jingdong ** to choose,Free shipping,**Licensed,Invoicing,National warranty,I bought it online there, 10X telephoto Sony DSC-H55,Jingdong also sells,**1599 yuan no giveaway,It's also very good。

If you are willing to pay an extra 700, it is recommended that you buy the Panasonic LX3

The effect is very good, it will be taken off the market immediately, so hurry up if you buy it.
