What is the Sigma lens?

Sigma is a Japanese company, founded in 1961 that manufactures cameras, lenses, flashes and other accessories from the world of photography. The Sigma lens is one of the brand's specialities.

They are lenses for professional cameras that are increasingly gaining prominence for their cost-effectiveness, i.e. great quality at a more affordable price. The brand manufactures lenses for its own cameras and other brands.

There are several types of Sigma lenses, specific for each click you wanted to capture. Whether you are a photography enthusiast or a professional in the field, there is a Sigma lens for your camera and your pocket.

Which cameras can I use a Sigma lens on?

As well as lenses, Sigma has its own cameras, but it's not just for them that the brand makes its lenses. The models are still compatible with the biggest names in photography on the market. You can find various Sigma lens options for Nikon, Canon, Sony and Pentax.

You can find various Sigma lens options for Nikon, Canon, Sony and Pentax.

Each lens has its own specification, which means that you should always check, in addition to the technical characteristics, for which brand and type of camera it is produced. If you buy a Sigma lens for your Sony, it does not mean that it is compatible with all types of cameras of the brand. The opposite can also happen.

Some models can be used on both a Nikon and a Canon, so the most important thing is to always read the description well.

What to watch for in a Sigma lens?

There are two things that are determinants of your Sigma lens choice. The first is the focal length and the second is the diaphragm opening, represented by the letter "f".

Focal length can have two classifications: fixed lens and zoom lens.

.The focal length may have two classifications: fixed lens (does not allow variation) and zoom lens (allows photographing at various distances). It is measured in millimetres (mm). The longer the focal length, the more limited is the framing. And the shorter it is, the wider the area of vision. Focal length is basically what classifies a lens.

You may have heard of wide-angle or telephoto, we'll talk more about that in the next section. It determines the type of photography you can do with your camera.

The diaphragm, on the other hand, is the aperture that the lens reaches for light to enter. The diaphragm can range from f/1.4 to f/16 and indicates the maximum aperture of a Sigma lens. You can find the maximum aperture value specified on the lens.

What are the different Sigma lens types?

Sigma has seven types of lenses. They are classified as wide angle, normal, telephoto, multi-purpose, macro, fisheye and OS, which stands for Optical Stabilization. Each line has several models with different technical characteristics, which may vary in relation to compatible camera, diaphragm opening and focal length. In all, there are more than 80 lenses available on the brand's website and it would be impossible to describe them all here.

We have created the table below for you to have a general idea of the characteristics of the seven types mentioned. This way you can delve into the one that is more your style.

Number of models Focal length Diaphragm Features
Wide angle 17 From 14 to 35mm From 1.8 to 5.6 Ideal for landscape and architecture
Normal 21 From 56 to 800mm From 1.4 to 8.4 Similar to the human angle of view
Telephoto 21 From 56 to 800mm From 1.4 to 6.3 Ideal for photographing what is further away
Multipurpose 5 From 18 to 600mm From 2.8 to 6.3 Lightweight, versatile and efficient
Macro 6 From 17 to 300mm From 2.8 to 8.4 To explore the details of something

Pillars of photography: What should I know to make good photos with a Sigma lens?

If you are already a professional photographer, you most likely already know all these terms. However, if you're an amateur or photography enthusiast, some may be new and confusing to you. Shutter, diaphragm and ISO are data that completely change the outcome of your photos, so you should master each of them. These terms refer to the three pillars of photography, which are the fundamental principles:

  • Sensor sensitivity (ISO)
  • Amount of light (Aperture)
  • Time of light (Shutter speed).

Understand now a little more about each of them, only this way you will know how to make the right investment in a Sigma lens for your camera.

  • ISO: The first tip you need to note is that the lower the ISO number, the lower the sensitivity of the sensor, and this results in less graininess in the photograph. In digital cameras, the sensor plays the role of film. The ISO can range from 50 to 25,600.
  • Diaphragm: We've already talked a bit about diaphragm. This "f" indicates fraction, and it is the aperture that the lens reaches for light to enter. In other words, the more open, the more light enters the Sigma lens, and this can influence the depth of field of your photo. This is the only variable value in a lens, so it's important to take a good look at it before buying.
  • Shutter: First let's clarify that the shutter is part of the camera and not the lens. It refers to the time it takes for light to enter and capture the image. As soon as you click to take the picture, the programmed shutter opens and closes at a certain speed. The higher the shutter number, the less light will enter because the faster the opening time. They can have slow, medium and high speeds and this changes the final result of the image.

Purchase Criteria: Determining Factors for Choosing a Sigma Lens

So far you have already received enough content when it comes to the Sigma lens, but it is normal that you are still in doubt, especially if it is a new subject for you. We've brought some points that can help you decide once and for all:

Check now in detail each of the mentioned criteria.

Purpose of use

You have seen in the previous sections that there are many different types of lens. And when it comes to a Sigma, there are more than 80 models available. Therefore, starting by defining your style of photography can be a great guideline. Check the table of Sigma lens types and think about which one meets your needs.

Technical characteristics

We talked about focal length and diaphragm opening. These are the two main points you should look at in your Sigma lens. Keep an eye on whether it has a fixed distance, or whether it allows you to zoom. And remember that it's these features that really define what your camera can do, so it deserves a lot of attention.

Measurements and weight

This criterion can be fundamental for those who live with their camera everywhere, especially those who carry their equipment on the plane. It may seem silly if you only have one lens, but it is essential for those who carry several types of lenses in their suitcase. Carrying a large or too heavy lens without the slightest need can be a real nuisance when it comes to making your shots.

Camera compatibility

We've already mentioned here that Sigma produces lenses for brands like Nikon, Sony, Canon and Pentax. It would be a real disappointment to discover you've bought the wrong lens. This criterion deserves attention especially from those who buy online.

Some models are compatible with different brands, others are quite specific. To avoid unpleasant surprises, always check the description.

Available budget

How about starting by defining your available budget? This can be a good search filter. After all, there is no point in looking for cameras worth thousands of dollars if you only have R$ 700, for example. In the market you can find lenses for all pockets. Try to find a good balance between your real needs and what you can afford.
