Sony FE 20-70mm f/4 G and Sony A7 V Review — Sony A7 V and Sony FE 20-70mm f/4 G

What a Wonderful Focal Length Range!

Standard zoom lenses have never been my cup of tea. I’ve always preferred a couple of smaller and better-performing prime lenses instead. When I talk about standard zoom lenses, I think 24-70mm.

Last year I had the Panasonic Lumix S 24-60mm f/2.8 lens for a while but sold it in a lens shuffle. The Panasonic 24-60mm was by no means a slouch, but as a reviewer I often buy and sell gear merely to get to the next lens for my reviews. Most often, selling a lens doesn’t mean that it’s a dud.

Now that I’ve stepped into Sony territory, one of the lenses I was eager to try was the Sony FE 20-70mm f/4 G. With the Panasonic lens, I often shot at 60mm and wished I had a bit more reach. The Sony lens takes me to 70mm and, perhaps more interestingly, it goes to 20mm on the wide end.

For my travels, which started this blog, I always brought a Fujifilm XF 14mm f/2.8 R lens (21mm full-frame equivalent).

Let’s see if the FE 20-70mm f/4 G will alter my view on whether to use a standard zoom or primes.

Introduction

The Sony FE 20-70mm f/4 G was introduced in January of 2023 and caught the attention of many, mostly due to the wide 20mm option in a standard zoom lens.

Compared to the Sony FE 24-70mm f/2.8 GM II ($2,448.00), the extra 4mm on the wide end is significant, but keep in mind you lose one f-stop, and the 20-70mm is a G lens, not a GM. The GM designation is Sony’s top tier.

At the time this review was posted, the Sony FE 20-70mm f/4 G retailed for $1,198.00.

Handling and Build Quality

The FE 20-70mm f/4 G feels terrific on the A7V and has a good balance-to-size ratio. The zoom ring is very smooth and better than what I recall from my Panasonic 24-60mm f/2.8.

The Sony lens is also slightly lighter at 17.2 oz (488 g), compared to 1.2 lb (544 g) for the Panasonic. It’s worth noting that the Panasonic lens has a maximum aperture of f/2.8.

The FE 20-70mm protrudes about 1.5 inches when zoomed to 70mm. As much as I prefer lenses with internal zoom, this does not bother me as much as it used to, and it’s not worth complaining about compared to longer telephoto lenses, where lens protrusion can be significant.

Unlike the Panasonic lens, the Sony lens has a de-clickable aperture ring for video shooters. I do wish the aperture ring had slightly wider grooves, which would improve handling even more.

The lens has 16 elements in 13 groups, 9 aperture blades, and a 67mm filter size.

Thanks to Sony Canada (Stewart) for letting me try the lens for a few days. Sony has not provided any input or narrative for this review, which is based solely on my opinion.

In Action

I had three outings with the Sony FE 20-70mm f/4, and as usual, it would have been great to have it for a longer period to try out in more situations.

I did, however, get a good feel for the lens, which, to me, shines the most for general travel photography when you have plenty of light.

I will get back to the caption above: “What a Wonderful Focal Length Range”. The ability to go from 20-70mm is very liberating in a walk-around lens such as this. 20mm is really very different from your typical 24mm zoom and can create more drama in your wide-angle shots.

I also appreciated the manageable size and weight of this lens paired with the A75. I could carry this all day without much bother.

In other zoom lens reviews, I sometimes show photos taken from the same spot at various focal lengths. Instead, this time I thought I would show the same scene, but back up as I zoomed from 20mm to 22mm, 28mm, 35mm, 50mm, and finally 70mm to see how the perspective changes with the chosen focal length.

Image Quality

I had wonderful weather for my first batch of photos from the harbor in Steveston, and the Sony FE 20-70mm f/4 G delivered excellent results with great colors and plenty of sharpness. In this type of environment, f/4 is not a limiting factor.

For the World Cup event photos in Vancouver, the lens also excelled, giving me a good variety of shots at various focal lengths. It was only when the light dipped (dusk) that I found the lens struggled a bit to deliver photos I was truly happy with.

At this point, I switched to a faster prime lens—the Sony FE 40mm f/2.5 G—which was better suited to this time of day. An f/1.4 lens would have been even better.

Below are two photos taken at the same spot, only minutes apart. I was impressed by how well the FE 20-70mm f/4 G compared to the FE 50-150mm f/2 GM. At this screen size, they look very similar, but when you pixel-peep, the 50-150mm f/2 lens pulls ahead with better sharpness and microcontrast.

Conclusion

At $1,199.00, I find the Sony FE 20-70mm f/4 offers good value for the money, as long as you are aware of its limitations. As an event lens, when the light drops, you should consider faster f/2.8 zoom options or even faster primes.

As a travel lens, however, this would be an excellent choice, especially when paired with a fast prime lens for low-light scenarios or to isolate your subject with a shallow depth of field.

I have nothing to complain about regarding handling and overall build quality of the FE 20-70mm f/4 G.

In the Sony camp, you also have the FE 24-50mm f/2.8 G lens, which is an interesting option if you favor a faster lens but can live without a more limited focal length range. I hope to test this lens at some point.

To answer the question I posed in my opening paragraph, I am still leaning toward primes for faster f-stops and ultimate image quality but would never snicker at zoom lenses as they have their place in many cases and offer flexibility.

Much will depend on your goals and the task at hand; often, it doesn’t have to be one or the other. Primes and zoom lenses can work in perfect harmony, complementing each other.
