What color filter should I use when traveling to an ancient town?

Commonly used filters include uv filter, nd filter, gradient filter, and cpl.

The main function of UV mirror in the digital era is to protect the lens.

ND lens is used to reduce the amount of light entering, which is very useful when shooting at a slow shutter speed during the day.

Gradient mirrors are used to solve the problem of large light ratio, allowing the highlights and dark areas to be exposed correctly at the same time.

cpl can eliminate reflections from water and glass, and can also make the sky bluer.

Others include color filters, starlight mirrors, etc., which are not used as frequently as the above ones.

It is not recommended to buy and use dozens of filters. The lens is a very precise optical structure. Adding a glass or branch filter in front of it will definitely cause damage. affect imaging. High-end filters can also minimize this effect, but low-end filters have a greater impact on imaging, and some inferior products can also affect focus.

In fact, you don’t need to buy a UV lens for your kit lens. A high-end UV lens costs thousands of dollars, which is almost the same as your lens and is not worth it; buy a low-end UV lens. It also affects the imaging. Originally, the imaging of 18-135 is average, and it will be even more meaningless if it drops further. Filters with other effects should be decided based on whether you need them.

If you must buy it, buy a Kenko UV mirror worth more than 100 yuan. You don’t need it at ordinary times and put it in your camera bag. When it rains or goes to the beach, temporarily install a lens to protect it.

If you want to buy one, just buy a filter with the same caliber as your lens. The 18-135 lens has a 67mm diameter.
