Camera Lenses Explained: 7 Basics about Camera Lenses

Let’s face it – buying a digital SLR is a huge investment. The camera body, a lens or two, and a camera flash will easily add up to more than 1000$. That’s quite an expensive piece of equipment. And with time, you’ll start buying more and more lenses. For example, my Olympus camera lenses add up to much more than the initial camera body.

Because of the large cost of having good camera equipment, it is worth taking some time to protect your camera lenses. My Olympus camera lenses can easily get scratched, which would mean I would have to shell out quite a lot in order to replace it, since it’s not something that can get fixed. Fortunately, there are several ways of protecting your lenses, making them last much longer, and making them almost indestructible!

Method 1: Buy a camera hood

Each of my Olympus camera lenses has its own lens hood. This is extremely cheap, and while it doesn’t directly protect the lens, it does help. Without this lens, the impact forces that result if you drop your camera can break the lens frame and can shake up all the elements inside the lens. The hood helps reduce these impact forces. Furthermore, it also prevents unknown objects from easily striking the glass of the lens, which is a big deal!

Method 2: Buy a filter

Simply put, the best protection I have for all my Olympus camera lenses is a filter. These are placed in front of your lens, and unlike the camera hood, do directly protect the lens.

A filter can add effects to your pictures, and so can be changed depending on what effect you want. The most general purpose filter I have for my Olympus camera lenses is a UV filter, which removes UV rays. This does not affect the coloring of my images, which is important to me.

Filters come in a whole range of prices. I’d avoid buying the cheapest ones, since they may create some distortion in your pictures. However, the good quality ones are much cheaper than your lenses. Which would you rather replace if it breaks? A 50$ filter or a 500$ lens?

Method 3: Use your lens cap

This should not really be even said, but I have seen many amateur photographers breaking this fundamental rule. Use your lens cap. Every lens has its own cap, and you should use it all the time! In fact, the only time your lens should not be covered with a cap is when you are snapping pictures.
