Canon DSLR 500D 55 250 What kind of lens is it?

If you're shooting a lot (often shooting with a handheld camera), it's highly recommended to choose a lens with stabilization (with IS) and a tripod or monopod if you're shooting at a fixed point. Otherwise, it is easy to cause the picture to be unclear due to slight shaking. If funds allow, try to choose a large-aperture lens, so that the picture is sharper and brighter.

For example, Canon lenses with the word L.

In addition, you should choose an 18-55 or 18-85 lens, so that the shooting requirements can be met when the short focus is short.

The new 55-250 dog head was used to hunt birds for the first time today, and it happened to be a cloudy day. The feeling of use is that the focusing speed of the dog head is not bad when the focal length is fully pulled to 250. Since all of the people I came into contact with today were smaller, I shot with a focal length of 250, and at closer ranges (about 6-8m), the image of this head was good, quite sharp, and even with ISO400 images it was acceptable.

However, the film looks mushy after distances greater than 10m, perhaps due to the lack of shutter speed in handheld shooting, but it is enough to prove that the IS stabilization effect of this head is not as strong as advertised to reduce the shutter speed by 2-3 stops. This is the first time I feel like slapping a bird with a dog's head.

It is suitable for shooting long shots, and has a strong sense of space compression. It is suitable for scenery, people, and daily street sweeping.

Big nose, small body Mine is 550d with 18-135 I already feel incongruous Your estimate will be more terrifying.

55-250 is a more traditional telephoto lens in Canon's half-frame SLR system, a generation of products seems to have been available in 2007, and the one on your picture should be the 2013 STM version, which is the third generation. Although there are differences in appearance and optical structure, on the whole, the volume and weight of the three generations of products are about the same (the focal length and aperture are definitely exactly the same), in short, it is a very mature product series.

The 55-200 half-frame micro-single lens was launched in 2014, basically even if it is a facelift on the basis of 55-250, the main change is that the volume is greatly reduced, the weight is reduced, of course, the focal length and aperture are also slightly reduced, the changes in the optical structure are relatively large, but the functional characteristics are still basically the same, especially compared with the STM version of the 55-250, in short, there is still little difference overall.

Therefore, these four lenses are basically in a product series, and it is recommended to buy the EFM55-200 with the native mount, which is much better than the adapter scheme in terms of volume and weight.

As far as the description and ** are concerned, both lenses are considered large zooms. The imaging effect is actually about the same, and you have to experience the focal length before you buy this lens.

So if you are study-oriented, the latter is recommended. 55-250。At least the focal length is longer.

I don't know how to continue asking, satisfied.

The focal length of the two is about the same, which is more expensive and which is better.

The Canon 55-250 lens is suitable for portraits and distant stills.

Canon 55-250 lens is a special lens for cross-frame machines, the focal length is equivalent to 88-400mm, this focal length is a more suitable focal length for portraits, but unfortunately the aperture is not large enough, the usefulness of this lens is that the maximum focal length is 400, it belongs to telephoto, and it is still possible to shoot a still scene in the distance.

One of the advantages of the telephoto head is that it is really convenient to shoot some flowers and plants, and there is no need to bend over, and the telephoto brings a very good sense of bokeh and layering.

This lens is a special lens for the cross-frame machine, the focal length is equivalent to this focal length is a more suitable focal length for shooting portraits, but unfortunately the aperture is not large enough, the usefulness of this lens is that the maximum focal length is 400, it belongs to the telephoto, and it is still possible to shoot a still scene in the distance. If it is used to shoot birds and grab shots, it is more difficult.

Portrait, telephoto landscape, zoo fighting animals. In contrast**, the imaging is stunning.

It's also suitable to shoot the stage, long enough, haha.

Portrait Canon EF 50mm F STM (Small Spittoon 3rd Generation) is good.

1. The Canon EF-S 55-250mm F is captures portraits with 50mm, 80mm focal lengths, or telephoto ends, with good sharpness, but due to aperture limitations, the background blur effect is average.

2. There is no weak brigade in fixed focus. The Canon EF 50mm F STM (Small Spittoon 3rd Gen) multiplies the coefficient on the APS format body, with its optimal portrait focal length of 80mm and a large aperture, resulting in sharp subjects and oily backgrounds, plus this inexpensive ** is the most cost-effective portrait head available today.

Three generations of Canon lenses.

Portrait is one of the subjects we shoot the most, and the portrait head must contain several elements: first, the aperture must be large, so that you can control the depth of field as you like; Second, it is necessary to have a suitable focal length (85mm, 135mm, 200mm, etc.) to ensure that the angle of view and perspective of the lens can conform to the habits of the human eye, rather than exaggerated like a wide-angle lens. Basically, the lens that satisfies these two items can be called a "portrait head".

Canon 50 ; 85 Both of these works pretty well.

The head of the half-frame camera is very suitable for shooting portraits, 55-250 is generally not used too much, and even if it is zoomed in, due to its aperture limitation, it cannot shoot the bokeh effect of 50, and 50 is the most practical for portraits, and this lens is generally a must-have for people.

50 Portraits will be much more ruthless.

Because the aperture is much larger, the bokeh is good.

Of course, the portrait 50, 55-200 is better in the medium telephoto, and the theme in the small category is better.

When shooting people, 50 is stronger than 55-250

After all, the aperture is two stops larger.

Advantages: The color is restored, the close-up performance is good, the aperture size is suitable for the disadvantages: the focus in the dark is slow, the focusing sound is slightly larger, and the bayonet is about 1500 plastic.
