What is the difference between Canon's 18- 135 and 18-200?

These two lenses have a large zoom ratio, and their advantages are easy to use and reasonable price. Some of them say that it is reasonable to go around the world in a mirror. The disadvantage is that the image quality is sacrificed. If you pursue good image quality, you should buy this lens carefully.

Canon 18- 135 lens and Canon 18-200 lens are all full-focus lenses, but 18-200 lens has a full focal length, so it is not necessary to equip a telephoto lens later. The lens of Canon 18- 135 is short and complete, but the focal length of Canon 18- 135 lens is not enough to shoot birds or take distant scenery photos. But for imaging effect, Canon 18- 135 lens is better than Canon 18-200 lens. Because the large zoom lens is easy to use, the imaging effect is worse than that of the small zoom lens. So I recommend you to buy a Canon 18- 135 lens, which is enough. If the focal length is not enough, you can add a telephoto lens later.

Canon 18- 135 expounds that Canon EF-S18-135mm f/3.5-5.6IS is a high-magnification standard zoom lens with a zoom ratio as high as 7.5 times, and the focal length can cover 29-21after being converted into 35mm specifications. IS (image stabilizer) mechanism can obtain hand shake compensation effect equivalent to about 4 shutter speeds from wide-angle end to telephoto end, and can automatically identify normal shooting and follow-up shooting.

Canon 18-200 expounds that the IS optical anti-shake effect of EF-S 18-200mm f/3.5-5.6 IS lens is remarkable when shooting with a hand-held camera, which is equivalent to increasing the shutter speed by about 4 steps, and clear images can be obtained even when shooting in a dark environment or indoors. In addition, the lens can automatically judge whether it is a follow-up, thus automatically adjusting the anti-shake mode and improving the success rate of follow-up. The optical structure of the lens is 12 groups 16 lenses, including 2 UD ultra-low dispersion lenses and 2 high-precision glass-cast aspheric lenses. By optimizing the lens position and coating technology, glare and ghost phenomenon can be reduced and the optical quality of the lens can be improved. The closest focal length of the lens is 0.45 meters in the whole zoom range, which has excellent close-up function. With the circular aperture design, you can take a beautiful blur effect. EF-S 18-200mm f/3.5-5.6 IS lens is also equipped with a zoom ring locking device, which can prevent the lens from stretching automatically and avoid friction after locking, thus better protecting the lens. The lens is made of environmentally friendly lead-free glass. The aperture of the filter is 72mm.

Speaking of the difference between them, the focal length is obviously different, one is 135mm, the other is 200 mm, and the Ud lens and aspheric mirror are x 1 and x2 respectively, and the price is obviously higher than 18- 135. However, personally, such a "dog head" is not worth buying, and the price/performance ratio is not very good. You'd better choose other lenses, such as 70-200/2.8, or other lenses. 18-200 has been discontinued and I don't want to buy it. After all, the lenses are too old.

Canon 18-200 (telephoto) is 65 mm more than 18- 135 (medium telephoto). Its difference is that the scene is pulled closer than 18- 135, which is convenient for framing and composition (to minimize unnecessary clutter background). These two lenses are suitable for macro, portrait (close-up), architecture and landscape photography, but 18-200 is longer than 18- 135 in close-up and bird shooting. In post-processing, if PS is used properly, it will have good expressive force. As a photographer,' weapons' are good and bad, just look.

How do you use it? Don't be influenced by some "ideas". Practice can produce "true knowledge". The above picture "Egret Walking" was shot with Canon 18- 135 (photo by Luo Tian).

My entry level, Nikon 18- 105, feels playable.

The second generation lens of Canon 18- 135 is much better than the first generation, and the lens lock is also better than that of 18-200.

The simplest difference is the difference between the two. 135 pan/tilt has a price difference of thousands of yuan compared with 200 pan/tilt, but 135 pan/tilt is equipped with usm mute motor, so you can hardly hear the sound when zooming, while 200 pan/tilt is stm, and there is no mute motor, so it will make a rustling sound when zooming, which is also the biggest short board of 200 pan/tilt, but if the two pan/tilt are compared, it's a pity that I choose/kloc-. Usually it's okay to take photos and videos, but if you take him and want to see the beautiful woman across the street, you will have a general feeling. If only it were closer, this might be the difference between 135 and 200!

My camera is a lens of 18/ 135, which feels good and is very handy.

There is not much difference. It's all dog heads.
