What is a prime lens?

Do you have a prime lens? Every DSLR owner should have a quick fix for their camera bag. The zoom lenses are perfect and can reduce weight and costs. When the situation requires it, a big lens can always be the closest companion to a photographer. The attached article will tell you what a premium lens is and how you can focus on improving your photography.

Prime lens vs zoom lens

In the past, the average photographer avoided zooms. A prime lens, called premium lenses, was faster, lighter and more affordable. More importantly, premium lenses and sharpness.

Fortunately, lens manufacturers have the ability to dramatically improve their lenses. For most photographers in the world, most photographers can cope with two or three decent zooms. Obviously, there is something else, and there are many situations where there is an unparalleled choice.


In general, it is easier and less expensive to produce a fast focal length with a single zoom, and few can match the low-light properties of a high-end lens. Primary lenses with maximum openings of f/1.8 or greater are common. In contrast, most zooms have an f/4 or something similar. In fact, even the most popular and expensive zoom lenses sometimes exceed the maximum aperture f/2.8. The light-gathering characteristics that prevail at a decent premium can create a gigantic contrast. In reality, you can increase the ISO value to increase shooting capacity with less light. However, a high ISO sensitivity can cause quality problems. At the point where the available light is low and you prefer not to break a flash, your fixed focal length can save the day.

Image quality

I already said that the zooms are consistent with the main objectives. In general, the optical requirements are to create a larger lens. Although there are really fantastic zooms on the market, many zooms are preferred over others at certain focal lengths. Photographers talk about the sensitive area – the focus area Sharpness and contrast can persist at other focal lengths. Again, this is not valid for all zoom lenses, but rather for the general rule, it is much easier to set an incredible high-end lens than to consider a really sublime zoom lens. Large lenses are therefore numerous, while excellent zooms are rare (and expensive).

Height and weight

In general, a fixed focal length is much smaller than a prime lens. The zoom requires more internal components and there must be a mechanism to get closer. In addition, zoom quickly with a specific target to collect the most light. Therefore, a fast zoom is usually bigger and heavier than a primary lens. This is important if you want to use your DSLR as a lightweight camera. The subtle primary lens also facilitates the capture of models, because the lens is much less visible than the wide angle zoom.
