When it comes to lenses, zoom lenses, in general, are unquestionably great, especially when talking about versatility and convenience. It is known to deliver a wide range of focal lengths in just a flick of a wrist. Still, they demand a huge amount of compromise when it comes to outright image quality. However, when dealing with complex arrangements of bigger groups of lens elements you need to adjust back and forth just to enable zoom. Sadly, this makes the purity of the optical features suffer.
For example, sharpness is usually the first one that suffers. At the same time, pin-cushion and barrel distortions usually appear at the telephoto and wide-angle lens of the zoom range. At the same time, you may also be able to expect a significant increase in the so-called chromatic aberration, as well as vignetting. The latter is usually seen when using large apertures at a wide-angle end. For this reason, it is a generally accepted fact that zoom lenses are usually prone to flare and ghosting.
All of these are not a problem with high-quality prime lenses. Vignettign and distortion are less noticeable, while sharpness can also be expected to be excellent. This means that you can easily optimize the high-resolution sensors that are fitted to the modern models of digital cameras.
Transforming Your Photography Experience
Another extra feature offered by prime lenses is that they are generally faster. This only means that they have a bigger maximum aperture, allowing for faster shutter speeds. These faster lenses are not just for preventing camera shaking, or freezing the action in most low-light conditions.
Another huge benefit that you can expect is that you can also get a tighter depth-of-field, allowing you to easily isolate the main subject in a shot and simply blurring the background. This is a well-recognized trick in portrait photography, particularly when the background is a bit cluttered and can serve as a distraction.
It may turn out to be quite challenging to use large apertures in sunny and bright conditions. However, you can easily get around with this by using a Neutral Density (ND) filter. Using variable NDs are an amazing option as you shoot video, and would like to achieve that shallow, cinematic depth-of-field which everybody has been talking about.
A very important factor that you need to consider as you purchase your Canon prime lenses is the focal length that you need to go for. Back then, a 50mm prime lens was often considered as “standard”. The reason behind this is because you can expect similar perspective when viewing a scene using your own eyes, without shrinking using a wide-angle lens, or magnifying using a telephoto lens.
With the obviously wide range of options on sizes that are currently available, choosing the best one can be quite challenging. However, by identifying first the purpose of use on your camera and the output that you would like to achieve, you will be able to choose the best one for your DSLR.
