    • Six FLD, two SLD, and different element coatings are aimed at reducing chromatic aberrations and flares as possible.

The Sigma 24-70mm f/2.8 lens is a popular lens and it is unsurprisingly one of the best lenses for the Sony a7iii. Despite this lens being a zoom lens ranging from wide-angle to telephoto, it maintains its f/2.8 maximum aperture at every zoom range. This quality makes this Sigma lens suitable for video shoots in all kinds of lighting scenarios without producing unnecessary noise. 

In addition, the constant maximum aperture allows for users to work with various depths of field at any zoom range. As for the focus, this lens uses the fast and silent stepping motor mechanism, and it also has an AF algorithm that helps with tracking subjects in cases of random movements. 

The Sigma 24-70mm f/2.8 lens uses optical elements that are designed to reduce chromatic aberrations, flaring, ghosting, and color fringing at every zoom range. The minimum focusing distance is different for each end of the zoom range, as well as the magnification factor although both are enough to achieve great close-ups.  

As for the build of this lens, it is built for both outdoor and indoor use with a dust and splash resistant design. This lens includes a zoom lock switch for keeping the zoom extension on point, a switch for changing between autofocus and manual focus, and also a customizable button that can be used for easy camera settings.

How to Choose the Best Lens for Sony a7iii

Using the Sony a7iii for video coverage means that an individual is ready for some serious videography work because of the specs the camera is packing. Therefore, it is only appropriate to use the best lenses for Sony a7iii to get the best of the camera. 

While every lens that fits the Sony E mount will theoretically work with the Sony a7iii, picking the best ones available can be a tricky task since there are so many. Furthermore, the lens options for the Sony E mount also include lenses originally designed for the Sony A-mount although this can only be achieved with the aid of an adapter.

So, what are the most important considerations for picking the right lens for the Sony a7iii? Here are some key criteria to keep in mind when making a lens acquisition for this camera. 

  • Area of Use

While a lot of lenses offer versatility, especially with creative handlers, some are better suited for some scenarios than others. A good example is using a 35mm prime lens for making wildlife videos. While this may be okay, the result will not be as satisfactory as using a zoom lens with a large zoom range. 

Specifying the area of use greatly reduces the option of lenses available to use with the Sony a7iii. Generally, prime lenses are preferred for making movies and general videos. Of these prime lenses, wide-angle and standard lenses are also preferred due to their ability to contain more details when capturing.

While the best prime lenses for Sony a7iii are preferred for making videos, this does not negate the quality of zoom lenses when making videos. Zoom lenses are especially good when large distances need to be covered without the cameraman moving too much. Zoom lenses are preferred for sports videography and wildlife. 

While there are different types of videography with their best lens fit, the acquisition of different lenses will allow individuals to engage in any kind of videography they want.

  • Durability

Lenses are made of a combination of differently shaped glasses to help get the perfect image. This means they are vulnerable, especially when handled without care. While a lot can’t be done about the use of glass in lenses, manufacturers are making the lens bodies more durable, especially with outdoor use. 

However, not every lens compatible with the Sony a7iii is truly durable or can withstand bad weather conditions. It is therefore important to look for lenses with guaranteed durability and special protections against bad weather, splashes, dust, e.t.c. 

  • Focus

Focus(1) is an integral part of the lens. However, there are different focusing criteria which are usually the difference between a great lens and an ordinary one. Lenses used for video recording need better focusing features than lenses used for stills. These include the best budget lenses for Sony a7iii. Some of the important focus features to consider are:

  1. Depth of Focus: The depth of focus refers to the amount of information in focus on a particular image. This is very important with video recording because bringing subjects out of focus and back into focus is very vital to conveying information to the viewers.  Lenses with wide apertures and good aperture ranges are generally better at achieving different focus depths. In fact, the wider the aperture, the more you can reduce your focus depth, which is actually great for isolating your subject. 
  2. Minimum Focusing Distance: This refers to the smallest distance a cameraman can get to the subject before it goes out of focus. This feature is especially important when it’s time for closeups. The MFD combined with the magnification feature of a lens can really be useful in video recording, especially when the videographer needs to enhance detail. On a side note, there are lenses made for this kind of imagery. 
  3. Focusing Mechanism: The focusing mechanism on use in a lens is what determines the speed of focus, the smoothness of the focus, and the quietness of the focus. These three criteria are very important to make a nice video. You want to make sure the mechanism is fast, silent, and smooth enough when bringing subjects in or out of focus. An added advantage for a lens is its ability to achieve focus tracking although this feature is present on the Sony a7iii.
  • Optical Elements

Due to the mechanics of a lens, including the best wide-angle lenses for Sony a7iii, every lens is subject to one optical challenge or the other. Some of the common ones include distortion, color fringing, vignetting, ghosting, flaring, and a lot of other chromatic aberrations. However, lens manufacturers are making sure to correct these natural errors by using specially designed elements in the lens’ build.

While a lot of lenses have these special elements designed to reduce optical aberrations, some others don’t. And since no one wants their perfectly taken videos coming out with color hues or distortion, it is quite important to check for the lens’ provision against aberrations.

F. A. Q

Yes. You can use a Sony A mount compatible lens with the Sony a7iii. However, this is only possible with the use of an adapter. In addition, some lens features may not be transferable through the adapter.

Standard prime lenses are the best lens choice for general videos because they are the most versatile of the different lens types.

Conclusion

Picking the best lens for Sony a7iii is important because it is the only way the true quality of this camera can be optimized. While our lens options make for easy decision making, choosing a lens for this camera by yourself is easier with our tips on choosing the best lenses.

While every lens on this list is good for making videos, the best one still remains the Sigma 24-70mm f/2.8 DG GN art, not only because of its awesome features but for the price point at which it can be gotten.
