The best lenses for Sony A7SIII

What lens to get for your Sony A7SIII?

In September 2020, the new Sony A7S III hybrid camera made a highly successful market entry. Initially intended for professionals, both photographers and videographers, who are looking for versatility and high quality, this full-format hybrid camera combines high sensitivity and speed. Heir to the A7S II, the all-new body has been completely redesigned to refine, among other things, recording quality, autofocus speed and five-axis stabilization.

With its new Exmor R CMOS sensor, full-format 35mm backlit, the Sony A7S III combines increased recording speed and superior image quality in both still and video. The 12.1 Megapixel sensor makes it possible to record the highest quality 4K 120p video. The stabilization of the sensor further increases the image quality. With its 759 collimators, it offers the precision required for fast phase detection and eye detection auto focus (Eye AF).

For improved low-light performance and noise management, the Sony A7S III is equipped with the new BionZ XR processor, which responds to these shooting situations with a range of ISO 80 to 102,400 in normal range and up to ISO 409,600 in dynamic range. Among the innovations of this magnesium body, the arrival of the articulated touch screen, on a ball-and-socket joint, greatly facilitates shooting, both in video and photo mode. It also allows quick access to menus. The camera is equipped with a new high-definition viewfinder, the most defined on the market, the OLED QUAD-XGA 9.44 Mp viewfinder, which ensures a very precise result and a more efficient use thanks to a 120p image refresh rate and full field coverage.

The Sony A7S III body weighs 699 g and its ergonomics have evolved with a new handle more adapted to a comfortable grip. Another point to emphasize: the adjustment menus can be made independently for photo and video, a subtlety that adds to the performance and fast execution.

The photo recording formats include JPEG, HEIF and 14-bit RAW, and in video the XAVC S and XAVC HS formats, in addition to compression formats for both modes. The box is equipped with an HDMI connector, a USB and USB-C microphone and headset jack, not to mention Wifi and Bluetooth. With its many advanced features, the Sony A7S III meets a real need and promises remarkable results.

Sony Zeiss Sonnar 55mm f/1.8

sony a7r iii which lens

Weight: 281 g
Filter size: 49 mm

This 55mm f/1.8 is the number one lens to buy for your Sony A7SIII. It offers a relatively versatile focal length that allows you to take both portrait and street photos, as well as landscape photos.

In terms of image quality obtained with this 55mm f/1.8, the results are impressive, especially in terms of the sharpness of the image, which is really sharp and rich in detail (it’s among the best rated on the Dxomark.com site).

Its matt black finish is very neat, and it’s tropicalized. It has a silent, fast and precise autofocus, even in low light. It’s above all one of the lightest lenses of the selection, and one of the least cumbersome.

Sony also offers two other options in the 50mm range: a much cheaper 50mm f/1.8 with performance that is far from as good, especially in terms of autofocus and colour rendering. The 55mm f/1.8 surpasses it on these points. There is also the Sony Zeiss FE 50mm f/1.4 Planar T*, with slightly better performance than the 55mm, but the difference is far from being huge to justify the price difference between these two lenses.

Although still quite expensive, this 55mm f/1.8 is an excellent choice if you are unsure about your first lens to buy for your Sony A7SIII.

Sony 24-105mm f/4 FE G OSS

which lens for sony a7riii

Weight: 663 g
Filter size: 77 mm

If you’re looking for a versatile lens for your Sony A7SIII, which you can take on a trip for example, then the Sony 24-105mm f/4 is the one for you! It’s part of Sony’s G range, so we are dealing with a lens with outstanding construction quality, which also offers superb image quality. Its focal length range of 24 to 105mm makes it very versatile, and its constant aperture of f/4 is a significant plus. It offers better optical performance than 24-70mm f/4, and is much lighter and above all much cheaper than 24-70 f/2.8

Its silent and fast autofocus is very useful for making video. In short, it’s one of the best standard zooms available for the Sony A7SIII.

Sony 16-35mm f/4 OSS

what lens for sony a7r iii

Weight: 518 g
Filter size: 72 mm

This is the very first wide-angle lens available for Sony FE hybrid cameras: overall its optical performance is excellent and if you plan to focus on landscape, architectural or interior photography, it’s a very good choice. It produces very sharp images in the center, with little vignetting and distortion. Its manufacturing quality is excellent and its development is fast.

On the same focal range, the 16-35mm f/2.8 GM is also very good and has a larger aperture, but its price is mainly intended for professionals or amateurs with a large budget.

In short, this Sony 16-35mm f/4 OSS is highly recommended if you own a Sony A7SIII and want to take a wide angle picture.

Sony 90mm f/2.8 FE MACRO G OSS

what lenses for sony a7r iii

Weight: 602 g
Filter size: 62 mm

If you like pictures of insects, flowers or any small close-up subject, the Sony 90mm f/2.8 offers outstanding image quality, with superb contrast, sharpness and bokeh even if its aperture is only f/2.8. It has all the qualities of a Sony G-Series lens: a fast and ultra-quiet autofocus, a very neat construction quality, and it’s resistant to dust and moisture. The only real disadvantage of this 90mm f/2.8 is its size and weight.

Its focal length is not only designed for close-ups on bees or locusts, it can also be used for portrait photography and will offer superb results in combination with the Sony A7SIII.

Sony 70-200mm f/4 FE G OSS

best sony a7riii compatible lenses

Weight: 840 g
Filter size: 72 mm

It’s one of the best zooms available for Sony full-format hybrids, if you take into account its price and size. It delivers very detailed images with superb contrast, its focus is fast and quiet and it’s very well built. Combined with the Sony A7SIII’s silent shutter release system, it’s the ideal tool for taking pictures from a distance while being discreet.

Compared to its big brother, the 70-200mm f/2.8, it’s half as heavy and expensive, and even if its opening is only f/4 it allows a very beautiful bokeh. It also remains compact and light enough to carry in its travel bag.

In short, this is the lens to buy with you if you are a long focal length enthusiast.

ACRONYMS AND ABBREVIATIONS TO KNOW

Because it’s not easy to find your way around, here are the abbreviations and terms you’ll often find when choosing your new lens for your Sony A7SIII:

FE: corresponds to “Full-frame E-mount”. Simply put, FE indicates that the lens is dedicated to Sony full-format cameras.

G: corresponds to ‘Gold’, Sony’s range of high quality lenses, which are rather professional and generally quite expensive.

GM: corresponds to ‘G Master’, the top of the range in terms of quality. Even better than the simple lens ‘G’.

OSS: corresponds to ‘Optical Steady Shot’, which is the image stabilization integrated directly into the lens. However, this is no longer a decisive criterion because most of the new Sony hybrid devices that come out have image stabilization integrated into their housing.

T*: indicates that the lens glass has a Carl Zeiss T-Star coating that eliminates stray light.

ZA: corresponds to ‘Zeiss Alpha’, and means that the lens was designed in collaboration with the German company Zeiss. It’s supposed to be a guarantee of quality.

Macro: designed for macro photography, i. e. the photography of small subjects (insects, coins…).
