Regarding the confusion of lenses, what are the factors to consider in the selection of lenses

It depends on what you do with it. If you are traveling and use it when you go out to play, it is recommended to go 18-200, one shot to go around the world, convenient, the picture quality is not as bad as **, and it is also anti-shake. If you are mainly shooting architecture or scenery, it is not recommended to use it, it is not realistic.

In fact, you can usually use 18-105, and the focal length is very practical. If you use D3100, if you don't guess wrong, you should be a beginner, learning photography, you need to shoot more, see more, compare more, find out where your interests are, and it's not too late to upgrade your equipment. Framing, light, and focus, all have to be honed, I wish you progress!

Under the current process conditions, buy a 10W 18 200 zoom lens, the image quality is not as good as a 600 yuan 50 header imaging quality, for a lens, its focus position is unique, expressed by focal length, the principle of the zoom lens is to increase the lens group behind this lens, change the focus position of the lens, and in the optics, but where the medium (glass, air) is increased, even if it is a vacuum, the light will be lost, so as long as the lens group that changes the focus position is increased,There will be a loss of light,Manifested in the image quality,That is, you see this image will be clear,But after magnification, it is still not as clear as the fixed-focus image。。。 Specific to the ball difference, color difference, and difference, it is more prominent. In the zoom lens, the greater the light magnification, the greater the light loss, the worse the image quality, the so-called light magnification is the maximum focal length divided by the minimum focal length, for example, 18 55 is 55 18 3, 55 200 , 18 200 11, so, this difference is not a little bit and a half, the difference is 108,000 miles.

It is recommended to buy a 50 header, **cheap,***, the pullover is all rubbish, and it will be very hard to learn photography with the pullover. Manifested in the market reaction, no one buys the second-hand market, no matter how low it is, the header is 600 yuan to sell a new one, and the second-hand can also be sold for three or four hundred.

Compared to 18-200 and 18-55 or 55-200, the picture quality is completely a grade, and even slightly wins. It is recommended to use it for a 18-200 when you go out for travel. If you have money, you can go up to another 50 or 35 to make up for the lack of a large aperture.

The picture quality 18-200 is poor, but it is convenient and does not need to change heads.

I think you can buy an 18-55 set first.

You don't have to buy it all at once, and if you feel that it is not enough in the future, you will add it. It is recommended to buy a better one, 55-200 is too bad.

You can consider Tamron SP 70-300mm F DI VC USD A005, 3300 yuan.

18-200's. Amateurs don't change lenses, and wide-angle telephoto has them. One done.

Forget about the lens of the dragon, the effect is not very good.

The most suitable lens is the 18-105 lens.

Why not choose 18-105 with a compromise?

A single head is recommended, and the difference is minimal.

The choice of lens, in addition to consideration, should also consider the resolution of the lens, the cost performance and the resolution of the lens.

The resolution of the lens. Every time a new lens is produced, there will be an authoritative evaluation, not only through the evaluation of the first shot, but also through a comprehensive data evaluation. In addition, it is compared with lenses from different manufacturers in the same class to basically determine which lens is at which aperture and which focal length (zoom lens) performs better.

Objective Shots: Shots taken from a non-dramatic spectator or neutral perspective. The vast majority of the shots in a film are objective shots.

It is responsible for narrating the plot, introducing the environment, portraying the characters, setting off the atmosphere and other drama tasks, as well as the artistic expression function of reflecting the style through the picture. Through objective narration and description, the audience can expand their horizons, participate in the course of events, and understand the characters.

There are two concepts of lens: 1. Hardware equipment in a simple sense, external lens of camera, optical components; Usually we also hear about prime lenses, zoom lenses, telephoto lenses, wide-angle lenses, and so on.

2. Lens screen. We call a shot or a clip between two editing points in a computer post-editing a shot; Usually we also hear, shoot me or edit a close-up, long-shot, close-up, etc.

Hope the above can help you.

The parallel optical axis of the "parallel lens" will be on the same horizontal line.

"The direction of the axis of sight of the lens is basically parallel or coincides with the direction of the axis of the person, and it is a synchronized (shifted) axis.

Happy to you!

It doesn't make much sense for you to understand these lenses, these are all lenses from film cameras back then. Today's digital cameras can be used for post-production, and the effect of these expensive lenses can be achieved.

It is recommended that you first learn the basics of photography such as aperture and focal length.

When it comes to choosing a shot, it depends on 2 factors: what subject you are going to shoot and how much money you are preparing.

If you want a universal travel head, consider focal lengths like 18-135, 18-200, etc.

If you specialize in portraits, of course, it is an 85mm portrait head.

If you want to take into account portraits and landscapes at home, choose focal lengths such as 24-70 and 17-50, and it is best to use a constant large aperture.

If you shoot macro, choose a macro lens.

If you still don't know what you need, use the set lens first, and then change to another lens when you understand it.

To put it simply, 18 135 means that this is a 135 18x zoom lens, with 18mm being its wide-angle end and 135mm being its telephoto end. And so on

f means that the maximum aperture of this lens is this value, and the maximum aperture of the DSLR sleeve is generally this value. Generally speaking, the larger the aperture, the more expensive it is. Note that the smaller the value after the "f", the larger the aperture.

What to pay attention to when choosing a lens... The topic is widespread. It depends on what you pay attention to.

For example, if you pay attention to practicality, you can buy a lens with a large zoom and go all over the world in one shot; If you pay attention to the quality of the lens, buy a lens with a small zoom factor and a large aperture (but such lenses are usually expensive). The larger the zoom factor of the lens, the greater the distortion and the more difficult it is to ensure the quality of the lens.

60d, if you are a beginner to the camera, it may be too advanced, and it is also expensive. 600d would be a little more suitable. The 600D is Canon's latest entry-level DSLR, with new practical features such as in-camera and offline triggering.

The parameters of the lens are marked with the focal length range and aperture of the lens, and these parameters are not clear in one or two sentences.

It should be that Canon has more advantages in portraits. As the saying goes, Nikon Rui Canon is charming... If you are sharp, you have to grind the skin in the later stage, so it is not as suitable as Canon.

The role of the lens is greater than that of the body, but the quality of the technology is much better than the quality of the equipment.

Let me give you an example: your eyesight is very good, and every time you are the master who only looks at the last line of the eye chart, which is equivalent to the body, and the pixels are very high! But I'll put a plastic sheet on the front of your eyes, how transparent can you see?

That's the shot. I won't choose your two configurations, if it were me, I would be 3000 yuan body, 80000 yuan lens. Because the body is an electronic product, it depreciates quickly, but the lens is different, and sometimes it can appreciate in value.

Moreover, the imaging ability of the low-end fuselage is about the same, but there is a difference between the control of noise and the durability of the fuselage, so the quality of imaging is more about the lens. To sum up, my personal understanding is that the camera body is important, the lens is more important, and the head behind the lens is the most important.

It must be the head of the 6000, the head update is relatively slow, basically not updated, the fuselage is very block, and the price is reduced, and there is no qualitative change. The lens is the one that deals with light, the essence

For example, three meters in front of you, there is a person standing, you can use 18mm to take a picture of his full-body landscape, and then you turn the lens, when the zoom is put to 35mm, you can also shoot this person three meters in front of you, take a picture of his 7 doppelgangers, turn to 50mm to shoot his half-body, 100mm to shoot his three-point body, 200mm to take a close-up of his face headshot, generally if you want to shoot a concert portrait of the actor larger, with 300mm or more, with 500mm to shoot birds and wild animals, Telescopes above 800mm, telescopes above 2000mm, almost that's what it means. 18 55 Compare yourself with what I have said above.

Set of heads, focal length of 18-55mm, that is to say, how much do you spend, buy a camera, is included in this lens**, the lens of the SLR can be replaced, in the same way, this lens can also be installed on the same brand of different body cameras, the camera and lens can be separate**.
