What To Know About Purchasing A Lens For Your DSLR Camera

Posted on: 22 March 2021

Are you purchasing your first DSLR camera and need to purchase lenses for it? If so, it will help to know the differences between the main types of lenses out there. 

Kit Lens

A kit lens is a common term used to describe the standard lens that comes with your camera. It is small and inexpensive, and it also has a variable aperture. It helps you get the job done and get great results with your photography, but it does have its drawbacks. The nature of being a variable aperture lens is that the f-stop is going to increase as you zoom in. This means that you will lose a notable amount of light when you zoom in, making the image darker as a result. 

Fixed-Aperture Lens

As the name implies, a fixed-aperture lens is going to keep the f-stop the same as you zoom in with the lens. This type of lens is larger, heavier, and more expensive, which is due to all of the additional glass that is in the lens to make it pull in that additional light. This gives it a huge benefit over a kit lens, but it may not be the right lens choice for every situation. You'll often see this type of lens used on the sideline of sporting events, where the photographer wants to get close to the action but can't physically be there to do it. 

Prime Lens 

What makes a prime lens unique is that it does not zoom in at all. You have to physically move closer to the subject to get that shot that you want. Why would you want this type of lens? The image tends to be much sharper than what you would get when compared to a kit or fixed aperture lens, which can benefit those that are doing close photography and don't need to zoom into their subject from a distance. 

Wide-Angle Lens

There are a few different types of wide-angle lenses that you can purchase for your DSLR. A fisheye lens is going to bow the edges of the frame and add additional curvature to the image to get a wide-angle view. This type of lens tends to be cheap and affordable for most photographers. A rectal-linear lens is going to be bulky and more expensive, but it stretches out the image instead of curving it so that the photo looks normal as you would expect.
