On wide angle lenses, which is more useful, a large aperture or VR

A wide aperture serves two purposes: it increases the shutter speed and lowers the depth of field.

VR has only one effect, reducing the safety shutter speed when shooting relatively static objects, but does not change the depth of field.

Only when a large depth of field is required, the wide aperture that VR can achieve may not be possible, and the wide aperture that VR can do in other cases can be achieved. The depth of field at the wide angle is already relatively large, and the applicability of a large aperture exceeds that of VR.

However, VR currently claims to be able to lower the shutter speed by 4 stops, and if you want to achieve the same effect with a wide aperture, you need to increase the aperture by 4 stops, which is more difficult. If VR can reach a safe shutter when it is F4, it is also necessary to achieve safe shooting, and the aperture must reach F1.

Therefore, you should make a choice according to your own needs and financial affordability.

Large aperture, because of the wide angle of the greater depth of field, VR is mainly used for telephoto.

Basically, most of the time stabilization is a money scam, and it's only useful when you need to use a shutter speed that's lower than the safe shutter speed but higher than the target movement speed. So there are only two scenarios available:

1. Telephoto lens mm lens;

2. Still life or scenery and other things that do not move.

But it's actually useless for still life or scenery. If there is no light, it will be dark, but if there is no light, what sketches and scenery do you shoot? It's also ugly to shoot.

Therefore, in addition to the large telephoto lens, anti-shake is a free money-making, and users of fuselage anti-shake are even more unlucky, most of the time it is useless, not to mention, there are more sources of failure, and other places on the fuselage that shake around are also more likely to break.

Depth of field refers to the distance in space at which images can be clearly imaged. For example, when shooting people, use a shallow depth of field, the background of the person is blurred, and the shallower the depth of field, the smaller the clear range. If you shoot portraits with a large depth of field, the background will be clear before and after.

Depth of field has a lot to do with aperture and focal length. At the same focal length, the wider the aperture, the shallower the depth of field, the more blurred the out-of-focus, and vice versa. At an aperture, the longer the focal length, the shallower the depth of field.

However, for most non-constant aperture heads, focal length changes may affect the aperture value (e.g., for lenses, the aperture can be opened up to the 18mm wide-angle end, but at the 105mm telephoto end, the aperture can only be opened up to the maximum; For such a lens, such a large aperture can be maintained at the full focal length of 24mm-70mm, so it is expensive).

The aperture is simply understood as the amount of light transmitted, which is expressed as an F+ number, and this string of aperture is getting smaller and smaller. The small aperture is generally used for landscape shots with a large depth of field, or for shots that require an extended ** time (such as shooting running water).

The wide-angle lens can shoot a wider range and is mainly used for landscape shooting. The telephoto lens can shoot people and objects farther away, and the composition can compress the space, which is suitable for shooting people and capturing distant scenery. Telephoto of 200 or 300mm or more is rarely used by ordinary enthusiasts.

Deep, as the name suggests, is the depth of the scene. Observe casually, we will find such a fact: the ** you shoot not only presents the subject you want to shoot, but also includes the scenery before and after the theme.

The meaning of depth of field refers to the depth of the spatial hierarchy that can be imaged on a ** before and after shooting the subject.

Depth of field consists of two parts. The spatial distance in front of the subject that can be clearly imaged is called the foreground depth; In the same way, the spatial distance behind the subject that can be clearly imaged is called the back depth of field, and the range of depth of field is the sum of the foreground depth and the back depth of field.

The aperture is a device used to control the amount of light that passes through the lens and enters the photosensitive surface of the body, which is usually inside the lens. To express the aperture size, we use the f-number. For the already manufactured lens, we can't change the diameter of the lens at will, but we can control the amount of light transmitted through the lens by adding a polygon or a circular hole grating with a variable area inside the lens, which is called the aperture.

A wide-angle lens is a type of wide-angle lens with a focal length shorter than a standard lens, a larger angle of view than a standard lens, a focal length longer than a fisheye lens, and a smaller angle of view than a fisheye lens.

A long focal length lens refers to a photographic lens that is longer than the focal length of a standard lens. Long focal length lenses are divided into two categories: ordinary telephoto lenses and super telephoto lenses. The focal length of a normal telephoto lens is close to that of a standard lens, while the focal length of a super-telephoto lens is much larger than that of a standard lens.

Take the 135 camera as an example, the lens focal length from 85 mm to 300 mm is an ordinary telephoto lens, and the 300 mm or more is a super telephoto lens.

Aperture is almost the most important indicator to measure the quality of the lens, large aperture means a larger aperture, which can significantly improve the amount of light transmitted, and better imaging in a low-light environment, thereby improving the resolution, in addition, the large aperture lens corrects the coma better after shrinking the aperture, and the sharpness rises more obviously, in short, the large aperture can do what the small aperture can't, and the large aperture lens gets better image quality at the small aperture.

The magic of this lens is that 14-24 is that as a zoom, in 14,21,24 three focal lengths respectively exceed the original fixed focus, breaking the law that the same level of zoom is not as good as the fixed focus, but the disadvantage is that the front group of lenses of this lens is too huge to use a filter, if you must use a filter, 17-35 gold wide angle will be better than 16-35, especially in terms of color, the aperture is one level larger and crushes people, the disadvantage of 17-35 is mainly that the imaging of the edge of the aperture is not as good as 14-24, The second is that the wide angle is shorter, because the safety shutter is the reciprocal of the focal length, and the aperture of this focal length does not require VR, and the extra set of lenses in VR will reduce the resolution.

Finally, a good tripod and filter are indispensable for shooting landscapes, don't think about holding them, even the safety shutter must also get used to the shelf, filters, leveling, low ISO small aperture, many times**, etc., excellent scenery films are essential.

24-end maximum aperture to shoot exterior portraits You can use architecture as the background I like this kind of large perspective 2470 doesn't need to be stabilized 1424 What's the hurry? Hand-held without hindrance.

Well, you're asking a question.

A wide aperture is a measure of a lens.

Ultra-wide-angle and large aperture are opposing issues in themselves, but they are mutually supportive.14-24 is ultra-wide-angle, because now the wide-angle lens is used more widely, and it is not a simple landscape, and the visual impact of still life is better when there is time, and when the scenery is in the small scene, the highlight of the subject is with a large aperture, and the large aperture is not necessarily used, and the aperture of the lens is generally better in imaging.

VR is not necessary, because at the wide-angle end, even jitter has little impact on the imaging of **, 14 and 16 are different2, but the visual impact is much worse.

Wide-angle is more about visual power, isn't it?

Says who?

Isn't 220is a large aperture for image stabilization?

Isn't the 428is also a large aperture for image stabilization?

If it is larger, it is 8512 or 5012, and the shutter is already very high when the wide circle of this focal length can be accommodated to reach such a large size, and there is no need to add the mechanism of IS to increase the weight **, but there are few opportunities for IS to be used.

How big is a big bai

It's generally around the right, Du n C, the 70-200 of the two zhi have anti-shake, and then the aperture is larger.

DAO image version F2 is 28-50mm focal length Generally, there is no need to prevent weight shake Besides, the aperture is large It can already increase the shutter speed by more than two stops Anti-shake will have a little impact on image quality Such a large aperture lens is based on image quality.

Do you mean that or yes? The zoom and fixed focus, in addition to the wide angle and ultra wide angle, have image stabilization, except for the earlier ones.

As for the need for this no update, it is decided by the manufacturer according to the market and its own technical reserves. As for it, I personally think it's very unnecessary, because the longest focal length of the lens is only 85mm, such a large aperture, there is no need to add anti-shake, and the manufacturing process of the lens is determined, large aperture lenses are generally relatively large lenses, one is heavy, and the other is that the lens is very bulky.

In short, there are many reasons, to summarize 3 points: 1. Market demand 2. Whether the sales volume of the lens after adding IS or VR is directly proportional to the upgrade cost 3.

Large-aperture lens, better sensitivity, larger incoming light, shutter and ** will also become faster, and the probability of pasting will be reduced a lot, so VR image stabilization has little effect on large-aperture short-range fixed focus lenses

Nikon 18-105mm, 16-85mm lenses!

Other Nikon 17-55mm is too expensive!

Since you have used the Tamron 17-50mm and the effect is not satisfied, then other sub-factory lenses are not recommended, and they are indeed not as sharp as the original!

Tamron 17-50 didn't feel sharp enough??? That can only be on the original 17-55, this is worth more than 7,000 yuan, and the second-hand is more than 5,000.

Try to see if sharpening in post meets your requirements.

That's the case,First of all,28mm or more sharp because the 18-55 automatic aperture has arrived,Or even smaller,This reduces the amount of light,You can achieve a certain degree of sharpness,Tamron's 17-50 image quality OK,The cost performance is also good,If you want to shoot sharp scenery,ISO 600-800 or more outdoors,Aperture value is generally around 9-11,Of course, it's best to use a custom style,To achieve a more vivid effect。

AF 20 35 "Diamond Wide Angle" used more than five thousand.

AF-S 35 DX Used in the early thousands.

AF 20 is more than two thousand second-hand.

Nikon, if you specialize in wide angle, taking into account the image quality and**, the gold circle is better than 16-35 4 VR, the f4 aperture is enough to shoot landscapes, the image quality is first-class and with 4 stops of stabilization, it is very useful when you need to reduce the aperture for a long time**, if you don't want to blur when you forget to bring a tripod, this head is better than 14-24 and 17-35, and** cheaper. The 18-35 is cheaper, but the wide-angle effect may be a little weaker on the cut-through. The 12-24 is a half-frame ultra-wide-angle, very wide, with similar results, so ignore this lens if you're playing full-frame.

The 28 is a lens for wide-angle portraits, cheap and with a large aperture, and good expressiveness. A 16-35 4 VR is recommended comprehensively.

Nikon 18-105mm, 16-85mm lenses!

Other Nikon 17-55mm is too expensive!

Tamron 17-50 is not bad! If it doesn't work, it's only fixed-focus.

AF head.

The landlord said the budget, I can recommend it to you. The brother upstairs recommended a few models to you, all of them are Nikon's, which are actually cheaper than the D5100, and there are quite a few models, like Nikon's D3100. Canon's 1100d 500d 550d These are beginner entry-level SLRs, **3800-5000.

However, if you are a novice, it is recommended to start with the sleeve, after all, the sleeve contains the focal length you need in your daily life, if the sleeve is not satisfied, you will know what kind of lens you need.

Also, for newbies, it is recommended to start with zoom. The image quality of the fixed focus is generally more than the zoom, but the fixed focus is not convenient, and the fixed focus is generally only suitable for enthusiasts or professionals who have high requirements for image quality. If you're a beginner, consider zoom first.

If you have high requirements for image quality, you can consider matching a 50 if you fix the focus, about 700, which is very cost-effective, with a large aperture, good bokeh effect, and a sharp weapon for shooting portraits.

If you want to shoot landscapes, consider a wide-angle lens, I suggest that you don't rush to buy a wide-angle lens, use the wide-angle end of the sleeve to shoot, the 18mm wide-angle end is also so wide, if you are really not satisfied, then consider changing to a wider wide-angle lens.

Look at the landlord's budget, I can give a specific recommendation.

If you shoot a macro, the last macro head, the landlord's budget is definitely not enough.

You can buy an adapter ring to reverse 50 to play macro, or buy a multiplier lens, two or three hundred mirrors, of course, the effect is definitely not as good as a special macro lens, but it's still good to play.

5-6K It is recommended to choose 600D is stronger than 550D, a little more expensive, but flip the screen, the new one, and then set the 18-55IS2 is good about 5200 (you can use fixed focus or 55-250 telephoto in the future).

Or the Nikon D5100 18-55VR is also very good, around 5200 (you can use a new fixed focus with a motor in the future, or 55-200 or 55-300 telephoto) is very good.

Compared to the 600d, the focus is a little slower but the sound is small, and everything else is basically the same.

The D5100 is a very good camera with entry-level parameters.

The absence of a motor is due to the fact that the speed of using the lens and focusing is still fast with a motor.

AFS can be used, but nothing else.

You can rest assured that the AFS lens is also direct autofocus.

If you want to use all Nikon lenses with motors, it's the D90.

It has all the characteristics of a mid-range camera, but the parameters are mediocre.

When I get started, I still have Canon Nikon

It is recommended to play nikon low-end ** low quality very well.

Affordable depends on your budget.

nikon d7000 d90 d5100 （d5000） d3100

cannon 60d 50d 600d（ 550d） 500d 1100d

That's all, there is a lot of no need to think about it, it's all from high to low (), don't think about the details, talk in detail.

Let's start with the fact that if the money is 4000, you can choose D3100

The D3100 is definitely inferior to the D5100

Regardless of the positioning time.

But if there is no motor, there is no pentaprism, there is no D3100, and it is still very cost-effective.

With your money, you'll really have enough for the D3100 and 1100D, and the 4000 will be split between the lenses.

So it is recommended to d3100 or 1100d first, how far do you want to go.

Basically, it can be said that D5100 can represent D3100, D5000, D5100

And 600d stands for 500d, 550d

At the same time, the focus motor represents the D90

For your question in short, 1,2 can be reversed.

1 I want to enter whichever house and communicate.

Nikon is out of the film at once.

Cannon post-processing.

2. Burn it later or not.

In the future, please do not burn the D5100 dual lens or 600D18-200 one lens to go all over the world.

After the small burn, please d90 set or 600d18-135 or 18-200 (depending on preference and funds).

After the big burn (5W), please 600d (Canon is absolutely high-end strong, Nikon low-end is strong).
