Within critical photography circles it’s typical that the most important element of a DSLR or compact system digital camera is the lens you connect to the front of it. Because of this it is usually advisable to invest wisely. Lenses are available in different styles and sizes and many are designed for particular functions, but the first element to take notice of is how the dimensions of your digital camera’s sensor will affect its natural focal length.

In this post I will highlight and explain some factors to consider when buying a camera lens.


An important factor to consider when buying a camera lens is its maximum aperture. This varies significantly, but a general rule is that the lenses with faster maximum apertures, or apertures that stay constant during the focal range will be bigger, heavier and costly.

The primary benefit of having a lens with a quicker aperture lets say a regular f/2.7 as opposed to f/3.5-5.6 – is that they’ll allow more light in, allowing you to use quicker shutter speeds in dim lighting.

Image Stabilization

Another factor to consider when buying a camera lens is Image Stabilization which is another useful improvement that helps to lessen the image-blurring outcomes of naturally occurring handshake effects at slower shutter speeds and longer camera settings, where handshake is magnified.

Photo Stabilization tech is normally implemented both inside the lens through a group of optics toward the back of the lens that flows to ‘correct’ any detected handshake especially in Nikon and Canon cameras and  through sensor adjustment in the digital camera body in Sony, Olympus and Pentax cameras.

Another factor to consider when buying a camera lens you is what want to use it for. If you’re seeking out a lens that’s tremendous for portraiture then a 50mm or 100mm f/1.4 prime may be best and if you’re searching out for single versatile lens to take touring then an 18-200mm f/3.5-5.6 may be your perfect guest.

Wideangle Lenses

Wideangle lenses make objects appear farther away and, as a result, smaller, than they do to the naked bearing eye. They are useful when you can’t move distant enough to get every details you want in shot, like when capturing a large Architectural building, an expansive view or shooting a large group.

However in addition they produce an obvious perspective distortion in which objects close to the camera can seem excessively larger than those in farther away. This is an impact that can be utilized by the photographer in all sorts of innovative methods. They also provide the illusion of placing the viewer in the focal point of the action, which makes them famous with reporting and road photographers.




Price is another factor to consider when buying a camera lens Just like with cameras, you get better performance when you pay extra. From my point of view, you should spend about 35% to 55% of your budget on the lens.

As an example, if you purchase a Canon T4i digital camera frame for $750, then you definitely need to be comfortable spending every other $450 to $550 on a lens like the Canon 50mm 1.4 and Canon 35mm 2.0.

In case you get the Canon 6D for $1,700 then you could pick out up the Canon 50mm 1.2 at $1,600.
