How much of an improvement the Canon EF 16 35mm F2 8Liii

This lens is a wide-angle lens, which is suitable for shooting landscapes.

The basic feature of a wide-angle lens is that the lens has a large angle of view and a wide field of view. The range of things that can be observed from a single viewpoint is much larger than what the human eye sees at the same viewpoint; The depth of field is long, showing a large range of sharpness; It can emphasize the perspective effect of the picture, show the foreground and express the sense of distance and proximity of the scene, which can enhance the appeal of the picture.

Therefore, wide-angle lenses are often used to shoot large areas of scenery, such as tall mountain scenes, wide buildings, large processions, and all indoor displays. The development is suitable, and the various levels of shadow tones expressed on the ** can be consistent with the light and shade of the original scene.

Shadow tone also refers to the tone of the whole picture, such as a certain ** is high (light) tone, low (dark) tone, or contrasting strong tone, or soft and flat tone, etc.

1. Differences in use: due to the aperture is one step larger, the shutter speed can be slower, the imaging is better in low light, the background blur is more oily, and the operation and use are of course more convenient.

2. The difference on **: it is twice the root number 2, F4 is twice the root number 2, and the values reflected by the aperture value are some square ratios; It can be said that the aperture is larger, and the actual lens area is much larger; With the increase in the cost of raw materials for making lenses, there will be many problems to be solved in optical design, and more optical technologies need to be used to eliminate the various optical problems caused by this "enlarged area". Therefore, don't underestimate this aperture is a notch larger, it takes a lot of manpower and material resources, so the price will be turned upside down.

It's good to say that the zoom lens is currently stopped, and there may be only one zoom lens at the moment.

Hello; The price of the camera's lens is not a little worse than a little worse, often a lot, the 16-35 you said is a wide-angle lens, but the aperture difference is one or two stops, the price is relatively large, which is determined by the technology, technology, and material in the production. Of course, the imaging situation is also very different, and the requirements for the environment when taking pictures are also very different. Therefore, the price varies greatly.

As for what you're talking about, of course it's better. All right.

If it's a full-frame body.

The usage rate is high, and it is sure that 24-70 Canon zoom mirror emperor 24 wide angle is enough for general scenery 70 end It is also very suitable for portrait shooting.

And also for 24 36 focal lengths the resolution 24-70 is slightly better.

The biggest advantage of the 16 35 is that the high-resolution, ultra-wide-angle is especially suitable for landscape photography with a lot of detail, such as a city overlook.

Of course, it is also suitable for large perspective, impactful landscapes, portraits**, which can shoot a strong sense of perspective.

Of course, it's also good to take panoramic shots in a narrow room.

For full-frame, 24, 70, 16, 35 are only needed.

If it is a truncated fuselage, 24 70 will be missing, and the wide angle will be 16 35, which is equivalent to 25 56 after conversion, and the standard will be changed, and the use will be larger.

Therefore, there are also interception cameras with 16 35 equal liters of full frame, and then 24 70 cameras.

Comparatively speaking, the lens usage rate of 24-70 will be higher.

1, Yes. 2. Yes.

3. Yes. It's not better, 16-35, it's a deformation, it will look like thick legs, and the picture quality is not good. So 24-70 is more practical. The premise is that you have to be full-frame, so that the 24 end is also wide-angle

The charm of 16 is unstoppable, the 35 portraits are good, the bokeh effect is quite good, and the connection is very natural. The inside of the focus is as sharp as a knife's edge, and the outside of the focus is as dreamy as foam.

Canon's best wide-angle zoom, good color, proper weight, beautiful appearance The ultra-wide-angle angle angle is very impressive. The large aperture is very good for dealing with low light.

The main thing is what do you want to shoot? When buying a lens, you must first determine what you want to shoot, and then buy a lens according to your needs.

16-35 scenic heads. Or you can take pictures of cultural scenes.

24-70 are mainly portraits and literary scenes.

You're right. The last one is suitable for portraits. Mainly look at how you use it. Hehe.

The aperture is large (the bokeh effect is good, and a large aperture is very necessary to shoot the starry sky), but it is heavy and expensive. The f4 aperture is small (which is usually enough), but it is light and cheap.

We need to understand the main uses of each focal length of the SLR:

8-16mm fisheye, spherical image 180° field of view, the picture is distorted.

16-18mm ultra-wide angle, large-scale shooting, exaggerated description of 180°-100° field of view, the angle illuminated is very large, very impactful.

20-24mm ultra-wide angle, panoramic architectural view, natural landscape, large crowd. 94° field of view, this focal length is good for tourist commemorative photos, and the left and right sides are slightly distorted in close-up photography, and the rigorous architectural panorama requires a large format and tilt-shift lens to correct the difference.

28mm wide-angle lens, wide scenery, crowded scenes, portraits with a sense of group. 74° field of view, suitable for general life photos, travel photos, group photos, and landscape photos.

35mm wide-angle lens, general landscape, architecture, building interior, documentary portrait. With a 62° field of view, the perspective of this focal length tends to be more live, a favorite of photojournalism, the quasi-wide-angle, which can accommodate more than the human eye can see, but it will not look like it.

Ultra-wide angles with a focal length of 28 or shorter, as well as a lot of extraneous stuff, are included.

50mm standard mirror, partial landscape, full-body portrait, any scene and subject. With a 46° field of view, the angle of view and perspective are closest to the human eye and are almost not deformed. Without the impact of a wide angle or the shock of a telephoto, it can be used in any scene and subject.

But there are more top-notch shots ever made with a 50mm lens than all other focal lengths combined.

55-65mm small macro, still life. It is suitable for shooting some items such as cup-sized objects or rice cookers, this coke.

segment is suitable for buying macro lenses.

85mm portrait mirror, ideal for portraits, still life 28° field of view, seven-parter, half-body, headshot. Slightly compressed.

100mm** macro, ideal for portraits. It is especially suitable for shooting macro subjects.

135mm portrait mirror, perfect for portraits. With an 18° field of view, this kind of lens is called a "beauty head", and those on the Internet are particularly beautiful.

mm, background blur, are shot with this focal length (generally put on an ordinary APS SLR with an 85mm lens, and a focal length of 135 can be obtained just because of the conversion factor).

200mm long shot, ideal for portraits, insect macros. 12° field of view, snapshot, close-up, doppelganger, half-body, headshot, full-body. Moderate compression.

300mm telescope, close-up Large birds, lotus, sports. 8° field of view, the vista is zoomed in, creating a hazy background.

From above, the best focal length for portraits should be 85-135mm (55-85 for APS-C format).From this, we can see that the 16-35 is not very suitable for portraits, and this focal length is more suitable for shooting landscapes and documentaries. But it's not the equipment that's important in photography.

Whether or not a portrait is suitable depends on the environment at the time, for example, shooting indoors at 35 focal lengths is definitely better than 85 focal lengths.

As a standard wide-angle landscape lens, 16-35 is rarely used to shoot portraits, and occasionally you can use 24-35 to shoot environmental portraits, but this wide-angle lens still has inherent flaws in the background blur effect and facial portrayal of people, and how to use it well is a test of the photographer's shooting skills.

The 35 end is okay, the 16 to 24 sections are not very suitable.

SuitableAccording to the restrictive frame of photography, compared with the 50 three suitable lenses, the disadvantages are obvious, and the bokeh ability is insufficient to highlight the subject.

However, if you think that the subject can only be blurred, it is a typical restrictive framework clause of photography.

But photography itself is very free, the characteristics of different lenses are advantages, and all the disadvantages can be compensated for by the ability to compose the shot, just depending on whether your skills are thick enough.

The first advantage that wide-angle portraits should take advantage of.

1. The visual impact brought by wide angles.

2. Close-up deformation (super cool long legs, this is especially very pleasing in front of the sister paper).

The biggest problem for wide-angle portraits is to learn how to highlight the subject on a solid background, and the entry-level solution is to highlight the subject by contrasting the tonal difference between the subject and the background.

Please be sarcastic and hostile to "portrait = blur", and those who believe in this clause must belong to the poor echelon in the photography party.

17-40 is a full-frame SLR lens, all Canon SLRs can be used, 15-85 is a truncated SLR lens, which can only be used on a truncation machine, because the size of the sensor of the truncation machine is smaller than that of the full-frame machine, the length and width of the sensor of the full-frame machine are times that of the cross-frame machine, so the angle of view on the lens cross-frame camera should be multiplied, which is the so-called equivalent focal length...

Therefore, the 15-85 lens can not be used in the full-frame camera, and the equivalent focal length of the angle of view on the frame cutter becomes 24-136mm, and the 17-40 is equivalent to 27-68mm on the frame cutter, but it is 17-40mm in the full frame, so it is wider than the 15-85...

Since you need a wide angle and scenery, buy 17-40 if you are a full-frame machine (6D, 5D Dx, etc.), and 15-85 if you are a cut-through machine (7D and two-digit and three-digit machines).

600d is a cross-frame machine, 15-85 is more suitable, the equivalent focal length of the angle of view is 24-136, the equivalent focal length of 17-40 is 27-68, which is easy to see at a glance, of course, if you change to a full-frame machine in the future, 15-85 can not be used.

600d or choose 15-85 is better, 17-40 in 600d wide angle loss is very large, although the difference between the two is 2mm, but the actual difference is very large.

Whether you use a full-frame body or a half-frame body, the full-frame camera recommends 16-35 with a larger wide-angle range, the half-frame machine recommends the Canon 10-22 15-85 17-40, and the wide-angle range is larger than the 10-22 lens, if you want to choose a good image quality Canon 17-40 lens, you can choose according to each person's requirements.

1424 Good! Let me tell you this, with the exception of a few prime focal points from Zeiss, the 1424 surpasses all 135 wide-angle lenses, including many prime lenses! Even Canon's vaunted 14 prime is a little inferior.

The nickname of 1424 Niu Wide Angle was not for nothing, and the TIPA Best Professional Lens Award that year was not won for nothing.

The 1424 is indeed a height that no other manufacturer can achieve in the 135 wide-angle zoom!

The image quality is definitely 35mm; Convenience is definitely 16-35, and 16-35 has a wider focal length angle. It's up to you to decide what you're shooting.
