Choosing a Budget Lens for Sony A7III Cameras

When it comes to choosing the best budget lens for Sony A7III cameras, it’s worth keeping in mind that while you can potentially get cheaper third party lenses that aren’t Sony designed or Sony branded.

Some of these lenses will require an adapter to use with your Sony A7III which will result in you losing some camera functionality like the ability to shoot with auto-focus. Even certain lenses that don’t require an adapter will be manual only and not compatible with a lot of functions. This guide won’t contain any manual only third-party lenses.

It’s also worth considering what type of lens you are looking for and the type of photographs you want to take. Are you looking for just one day-to-day lens that lives on the body of your camera nearly all the time? Or alternatively are you happy to be switching between two or three different prime lenses when shooting?

Finally, it’s worth remembering that the Sony A7III, A7II & A7RIII are premium cameras so even though some lenses listed below might not seem budget relative to other cameras, they are often significantly cheaper than the premium lenses available such as the G-Master series.

Best Budget Lens for Sony A7III

Below are some of the best budget lenses currently available for the Sony A7III and reasons why you might want to choose it as your next lens!

Vario-Tessar T* FE 24-70mm F4 ZA OSS

If you are looking for a budget lens for your Sony A7III because you want an upgrade on the standard kit lens or are after a quality budget zoom lens then it’s worth considering the Vario-Tessar T* FE 24-70mm F4 ZA OSS (also available from B&H Photo here or from Adorama here).

The Vario-Tessar T* FE 24-70 mm F4 ZA OSS offers a similar shooting range to the standard 28-70mm kit lens, producing quality images at its full range.

Weighing 426g (15.1oz) it is light enough to be used as a travel lens and is particularly suitable given you can shoot a wide spectrum of shots with the one lens and don’t need to be constantly changing lenses when on the road.

The Vario-Tessar T* FE 24-70 mm F4 ZA OSS, similarly to the standard kit lens, doesn’t offer any additional functionality on the body of the lens (such as an auto/manual focus switch). Nevertheless, if you’re after a budget zoom lens this is one of the best options available on the market.

Sonnar T* FE 35mm F2.8 ZA

If you’re looking for an everyday prime as your budget lens then the Sonnar T* FE 35mm F2.8 ZA (also available from B&H Photo here or from Adorama here) while at the higher end of budget lenses is a good option.

The Sonnar T* FE 35mm F2.8 ZA is the ideal focal length for every day shooting as this lens offers fantastic image quality in a small compact lens that is perfect for travelling. Weighing 120g (4.3oz) it is incredibly lightweight and its constant f2.8 aperture allows you to shoot in a variety of lighting conditions as well as the ability to create smooth bokeh in your shots.

The Sonnar T* FE 35mm F2.8 ZA can also work if you’re looking to upgrade your standard kit lens but prefer to shoot with prime lenses.

FE 28-70mm F3.5-5.6 OSS

If you’ve just bought the body of the Sony A7III and are on the hunt for a budget zoom lens, it’s worth considering the FE 28-70mm F3.5-5.6 OSS (also available from B&H Photo here or from Adorama here) which comes as a standard kit lens when buying the Sony A7III.

While we don’t typically include the standard kit lens in our lenses guides, the FE 28-70mm F3.5-5.6 OSS is undoubtedly one of the best options when it comes to using a budget zoom lens on your Sony A7III.

You can still capture quality images with the FE 28-70mm F3.5-5.6 OSS and as it weighs only 295g (10.5oz) it’s the perfect option for an all-in-one lens to use when travelling without breaking the bank. While you’ll likely want to upgrade at some point in the future, this is one of the best options if you simply don’t have the funds at the moment.

If you’re concerned that this lens isn’t wide enough for the wide-angle shots that you want to take, there is the option to purchase an ultra-wide converter, however, once you factor in the cost of the converter it might be worth considering the more premium FE 20mm F1.8 G lens instead.

Nevertheless, if you’re looking for a budget wide-angle lens manufactured by Sony then the FE 28mm F2 is one of the best options available.

FE 35mm F1.8

An alternative option to the FE 28 mm F2 or the Sonnar T* FE 35mm F2.8 ZA, the FE 35mm F1.8 (also available from B&H Photo here or from Adorama here) lens is a solid everyday prime lens that offers great image quality and the ability to shoot in low-light conditions.

Weighing 280g (9.9oz), it’s slightly heavier compared to some of the other primes listed in this article but does have the benefit of an auto/manual focus switch on the body of the lens.

The FE 35mm F1.8 is worth considering if you’re planning to do more night photography and also switch a lot between auto and manual focus as the switch makes this a lot easier than some of the other prime lenses listed here.

All in all, the FE 35mm F1.8 is a solid choice and one worth considering depending on your shooting preferences.
