Canon 450D with lens, just started to learn photography, want to match a medium telephoto lens, plea

That's obviously the Canon EF-S 55-250mm F IS, which is definitely suitable for getting started, very cheap, only 1600, and the focal length is perfectly compatible with your existing lens.

These lenses are more than enough for all your normal uses.

If you have the idea of upgrading to full frame in the future, it is recommended to choose 70-200 F 4is, commonly known as love to die Xiaoxiaobai, this is a very good lens. At present, it is more than 8,000 yuan.

Good luck!

Your two lenses add up to a little more than a thousand, 50 heads are not bad, 18-55 pullover is simply no different from the card machine, the lens is bought if you want to buy it, 70-200, in one step, if you have money, you can buy the aperture, if you have no money, you have to buy the aperture, then there is no way, as for the stabilization, it also depends on whether you have money, add an anti-shake for several thousand, I suggest, don't buy a cheap low-end lens again, or don't buy it, buy a useful one if you want to buy it, or it's a waste to buy it again, it's useless to put it in the future, It's a pity to throw it away, don't give it away, and look an eyesore

It's best to go directly to Xiaoxiaobai, like me, don't listen to the nonsense of Little Japan, spend more than 3,000 yuan to add an anti-shake, I don't shake at all. If you don't have money, you can also go to a dog's head telephoto first to have a good time, hehe, if you have time, you can go out to shoot outdoors together.

The following is already good! I'm not going to talk nonsense! ~

Since you have an 18-55 head, 17-85 doesn't have to think about it. The 50 prime head is very good for shooting portraits, and it is used on 450d, which is equivalent to 80.

1.Generally speaking, if the magnification of the lens exceeds 3 times, the image quality will deteriorate. The other two heads are more than 3 times.

2.But considering the use when mainly touring, it is recommended that you choose the head of 18-200. This head is called a mirror to go all over the world. The quality is about the same as 18-135.

3.From the bokeh angle, telephoto and wide-aperture bokeh will be better.

Constant large aperture lenses can't be bought at this price, so it's recommended to get a 55-250is, the focal length can be completely connected with the sleeve, and the telephoto end can also blur the background. It's one of the few low-priced and good-quality lenses in Canon's original lenses, and the IS also achieves a 4-stop shutter level with light weight, which is more balanced with the 450D.

There is really no such price point, and the portrait is still the best at 80mm.

18-135 Home Travel: A Dog's Head Necessary for Going Out to Kill Birds.

It's still wise to buy 18-135.

Weishua 14mm EF Wide-angle Fixed Focus Manual Focus 2600 yuan.

Tokina AT-X 116 Pro DX 11-16mm wide-angle zoom autofocus 3700 yuan.

Sigma's 12-24 is cheap and wide enough, and with 550d is equivalent to 19-38. In the future, the camera can be upgraded to full-frame. 12 sections of landscapes, 24 sections of small animals, hehe.
