If you're new to photography, you might be wondering what kind of lens you should buy for your camera. There are so many options out there and they can vary a lot in price and quality. How do you know which one is right for you?

In this blog post, I'll give you a lens guide for beginner photographers. I'll explain the different types of lenses, what they do, and how to choose the best one for your needs. I'll also tell what was my first lens for my Sony A7iii. Let's get started!

Compatibility with your camera’s sensor

The size of the sensor behind a lens does not affect the lens itself, but it affects how the lens (especially its focal length and aperture) influences the final image.

Among interchangeable lens cameras today there are three commonly-used sensor sizes: Four Thirds, APS-C and full-frame. When you use a full-frame camera, the focal length listed on your lens functions normally and will be accurate in the photographs you take. However, crop-sensor cameras have a magnification factor between 1.5x and 1.6x depending on the brand you use.

So, if you use a 100mm focal length lens on a full-frame camera, your images will truly reflect 100mm. If you use a 100mm focal length on a crop-sensor camera, your lens functions more like a 150mm focal length lens.

Types of lenses

There are two main types of lenses: zoom and prime. Zoom lenses let you change the focal length, which is the distance between the lens and the sensor. This means you can zoom in or out to get closer or farther from your subject. Prime lenses have a fixed focal length, which means you can't zoom in or out. You have to move yourself or your camera to change the distance from your subject. I made this article explores the differences and advantages of prime and zoom lenses.

How to choose a lens

The best lens for you depends on what kind of photography you want to do. Different types of photography require different focal lengths and apertures. Here are some common examples:

Of course, the suggestions above from each category are not rules to follow. Be creative and capture the best images possible in your circumstances.

The lens of my choice?

Budget lens?

Of course, lenses from the same manufacturer (Sony, Canon, Nikon) as your camera body will perform best, but for some brands there are alternatives. Like those from Sigma, Tamron or even Samyang. All of them have almost an equivalent lens of an already established brand, so if the budget does not allow you, you can confidently call on one of these third parties. I’m sure any of these will be a great starter lens for your photography!

Conclusion

I hope this budget lens guide for beginner photographers has helped you understand the different types of lenses and how to choose the best one for your needs. Remember, the best lens is the one that suits your style, your budget, and your camera. Don't be afraid to experiment and have fun with your photography!
