When it comes to camera lenses, there are many different types of them in each category. And each one of them has its own areas of specialty. Here, we’ll go through them very briefly before going into our buying guide.
Prime Lens
This is the classic style of lens existing from when the cameras were invented. The main property of a prime lens is its fixed focal length, meaning there’s no zooming in or out.
Their job is to focus on one type of photography, and having a fixed focal length makes it cheaper than zoom lenses. And it also produces better images. So, if your photography isn’t versatile, this is the lens you want to use.
It can take portraits, landscapes, and all sorts of shots if the focal length is right.
Zoom Lens
A zoom lens is the opposite of a prime lens. It’s all about versatility. The need for a zoom lens arose when photographers needed to do different types of photography in a single session.
With a zoom lens, you can go from landscape photography to portraits. But it does produce images with less quality compared to prime lenses. The most common in them is the 50-200mm focal length.
Telephoto Zoom Lens
If you’re not satisfied with a normal zoom lens, you can go towards the telephoto lenses. Their focal length starts around 85mm and can go up to 600mm or more. Although for most people, 600mm is more than enough.
They’re bigger in size and hard to control. If you’re someone who fancies wildlife, sports, night sky photography, then you should look at a telephoto zoom lens.
Wide-Angle Lens
These lenses are for one thing only, and it’s taking wide shots. They have the lowest focal lengths among all, which helps to focus more on the background than the object. They are perfect for landscape photography.
The focal lenses start from as low as 8mm and can go up to 35mm, but 24mm is a good limit to have. Those with focal length under 18mm are also known as fish-eye lenses or ultra-wide lenses.
What to Look for Before Buying?
When you’re on the market for a camera lens focusing on portrait photography, there should be some criteria to find the best canon lenses for portrait photography. In different scenarios, you’ll need different features to take the best photos possible. Let’s talk about them.
Focal Length
You’ll find a lot of lenses with the difference in focal length. Starting from as low as 8mm, it can go up to 600mm. But not all of them are good for portraits, especially those with small focal length.
If we were to put a certain limit on the minimum focal length, then it’d be the lenses with 50mm, and they’re also known as nifty fifty lenses. But the sweet spot starts from 85mm and up. Of course, the price also increases with focal length.
For most photographers, professionals, and amateurs, a good range would be 55-300mm.

Aperture
The aperture of a lens plays a vital part in the production of an image. It determines the amount of light entering the photo chamber. The bigger the aperture, the more light it lets in.
A narrower aperture is good for those situations where there is a lot of light. And wider apertures are good for low light photography because here you need as much amount of light as possible to enter.
Another effect of the aperture is the bokeh effect you want in portraits. Larger apertures such as f/1.4, f/1.8 are better, but f/2.8 is the minimum if you work with an 85mm lens.
A good combination of focal length and aperture size is needed to get good portraits. A good combination can be 55-300mm and f/2.8.
Image Stabilization
Make sure that your lens has some sort of image stabilization technology. If your camera has digital image stabilization, then that can compensate for the lack of image stabilization in your lens.
Types of Motor in Lens
There are three types of motors used in lenses. Most Canon lenses will have either Ultrasonic Motor (USM) or Stepping Motor (STM). Although the two have no significant effect on the image quality, you might want to prefer one over the other.
The USM is the fastest focus motor among Canon lenses, where the STM is known for its smooth and quiet focusing. So, the STM works better when taking videos.
When these two motors aren’t present, then it means that the lens is using a Direct Drive motor or conventional DC motor. It does have autofocus but not as fast as USM or as smooth as STM.
