Canon 55-250 or 18- 135 lens, which is better? Excuse me, photographer?

18- 135 lens is commonly used, and 55-250 generally needs to be used with 18-55 lens.

From the frequency of use, 55-250 is not as practical as 18- 135 lens. First of all, from the focal length, 55-250 lacks the most commonly used wide-angle and portrait focal length (the focal length of the 55 mm end of the lens is relatively long). As a portrait lens, I am a little reluctant to use it. There are few scenes in the medium telephoto lens, and the telephoto end is a bit too short. Birds generally use a focal length of about 400 mm, and the moon needs a little longer, which is not practical from the focal length. Common focal lengths must be equipped with 18-55 lens.

On the other hand, 18-55 and 18- 135 can be used as on-hook lenses, indicating that these two lenses are more practical in frequency than 55-250.

From the point of parameter analysis:

The focal length of 18- 135 is not as long as that of 55-250, but the maximum aperture of F4 is directly caused by using 58mm filter holder and 67mm filter holder at 55-250, and the maximum aperture of 18- 135 lens reaches F3.5

18- 135 lens adopts 12 group 16 lens, 55-250 lens only has 10 group 12 lens, and the bayonet at the back of the fuselage is18-/kloc.

On the whole, if there is no repeated focal length, it is recommended to choose 18- 135 lens. If there is already 18-55 lens, it only needs to spend less money to expand the focal length, and it is recommended to choose 55-250 lens.

This paper introduces the division and use of common coke blocks;

The division of SLR focal length generally refers to the different focal lengths of the lens, such as super wide angle, wide angle and so on, as follows:

10- 17 mm is super wide angle-shooting scenery, especially large scenes, such as grassland, desert and sea;

17-35mm wide angle-scenery and culture, especially suitable for travel shooting;

35- 135mm medium coke-humanities, portrait. The 85mm focal length of this focal length is especially considered as the best focal length for portrait shooting. The lens of 85mm F 1.8 that we often see is called the portrait head.

50 mm-this focal length is most suitable for people to look out, so it becomes the standard focal length. This is why the 50 mm lens is often called the "head".

135-200mm- telephoto, suitable for close-up of people, taking some lotus flowers, stage, etc.

135mm or more is considered as telephoto, which usually stops at 200mm, but some people like to shoot wild animals and birds with focal lengths of 300, 400 or even 600mm.

Macro lens-a macro lens specially used to shoot small things such as insects and flowers. Generally, one hundred microlenses are used, which is about 105mm.
