Zoom lenses vs prime lenses: The guide

A prime lens is a type of lens whose focal length is fixed while a zoom lens is one that has a variety of lens on one lens. The zoom lens has a wide variety of focal lengths and it makes it possible to shoot both wide and longer focal lengths. However, for primes lens, the user is required to move to achieve the best focal length.

There are therefore arguments for both lenses as follows:

Arguments for prime lenses

prime lenses

  1. They are high quality hence producing clean and precise shots.
  2. They are cheaper than zoom lenses. It is due to simple constructions as it requires less moving parts.
  3. They are lighter and even smaller those zoom lenses with the same focal length because of its simple construction. It is therefore convenient to move around with.
  4. Due to a wide aperture, it produces faster shots as compared to zoom lenses. This feature allows you to shoot in conditions of low light without flash.
  5. Using these lenses train you different techniques and earn you more creativity. It is because you move around to look for the best focal length, unlike the zoom lens whereby you just zoom in and out while in the same position.

Arguments for zoom lenses

Zoom lenses

  1. They are flexible since you can change focal lengths without much movement especially in situations where you are constantly looking for random shots like sports and even wedding.
  2. While zoom lens is more expensive than a prime lens, the cost of one lens in comparison to multiple lenses should be considered.
  3. Compared to the light weight of the prime lens, the zoom lens has only one lens with multiple lenses which can be carried around while you are required to carry several lenses for a prime lens which could be achievable with just one zoom lens.


The best lens to use depends on different factors like style and type of photography, budget, and many other factors. It is therefore advisable to have both types of lenses for quality production in the photography field.

Fisheye Lens Buying Guide

If you’re anticipating purchasing a fisheye lens, there are three things you have to know before making your buy: Knowing these three things can spare you a considerable measure of cash and frustration, also time squandered. To begin with, you have to know the contrast between a fisheye lens and a standard wide point lens. Many individuals confound the two and wind up purchasing being extremely disillusioned with the outcomes.

What’s the fundamental contrast?

The Difference between a Fisheye Lens and a Wide Angle

Not at all like a wide edge lens, a fisheye isn’t redressed for bending. Given this, they have an extraordinary 180-degree point of view and a picture portrayed by “barrel twisting.” A standard wide edge lens is rectified for twisting by including restorative lens components. Accordingly, the edge of view is diminished extensively yet with a picture that is significantly less contorted.

A wide point lens will dependably have an edge of view that is not as much as that of a fisheye lens of the same central length. Do you need a fisheye lens or would you say you are extremely searching for an ultra wide edge?

Right Lens for the Right Sensor Size

Another blunder many individuals make is the point at which they purchase a fisheye that was not intended for their cameras sensor estimate. By far most of the advanced SLR proprietors shoot with the APS-C estimated sensors with a harvest factor of 1.5x – 1.6x times. For example, on the off chance that you purchased a Canon 15mm full edge askew for your Canon 7D because you needed to make some cool fisheye pictures, you would be exceptionally disillusioned with this Canon Fisheye. What you wind up with rather is a wide point lens with a compelling central length of 24mm. (15mm X 1.6 = 24mm). To accomplish the “fisheye impact,” you would require a lens with a central length of between 8 or 10mm.

Here’s a general rule: If your shooting with a full casing camera like the Canon 5d Mark II or Nikon D700 then you require a lens with a central length of between 15 or 16mm. On the off chance that your shooting with a Camera that has the APS-C measured sensor, at that point you require something in the 8 to 11mm territory.

Purchasing The Right Type of Fisheye Lens

Another factor that is now and then disregarded is the “sort” of the fisheye lens. There are two particular sorts of fisheye lenses: Diagonals and Circulars. The inclining kind of fisheye is the most widely recognized compose and the most favored. These lenses delineate the 180-degree edge of view “corner to corner” over your edges sensor, so the picture territory is filled in with pixels. It’s consequently that diagonals are regularly called “full edge fisheye lenses.”
