Testing the Sony RX10 V on a Birding Walk

A 24–600mm all-in-one camera, bird recognition, lightweight field use, and where it fits for wildlife photography

Introduction

Most of my bird photography involves a fairly substantial amount of equipment.

A full-frame camera paired with a 200–600mm lens gives me the reach, autofocus performance, shutter-speed control, and image quality I want when I am specifically going out to photograph birds. But it also means carrying a large camera and lens everywhere I go.

The Sony RX10 V takes a completely different approach.

It combines a 20.1-megapixel 1-inch stacked sensor with a fixed 24–600mm equivalent F2.4–4 ZEISS lens, BIONZ XR processing, and a dedicated AI chip for subject recognition—all in one camera.

I took the RX10 V out over a couple of days with a simple question in mind:

The First Thing I Noticed: The Size

Before image quality, autofocus, or even that 600mm reach, the biggest difference was simply carrying the camera.

It felt incredibly light compared with the equipment I normally take into the field.

There was no separate telephoto lens. No second lens in my bag. No teleconverter. I wasn't thinking about which combination I should carry.

I just picked up one camera and started walking.

That changes the experience more than I expected.

Birding often involves several hours on your feet, and sometimes photography isn't even the primary goal. You might be exploring a new trail, listening for calls, looking for a particular species, or simply documenting what you encounter.

For that type of day, having everything contained in one relatively compact camera makes a lot of sense.

24mm to 600mm in One Camera

The feature that really makes the RX10 V interesting for birding is the lens.

Sony built it around a 25x optical zoom covering a 24–600mm full-frame equivalent range, with an F2.4–4 maximum aperture.

That is an enormous range.

At 24mm, I could photograph the environment around me.

At 100mm or 200mm, I could document a larger animal or a bird within its habitat.

And then I could continue all the way to 600mm when a small bird appeared farther down the trail.

There was no lens change.

For birding, that last part is especially important.

Why 600mm Matters for Birds

Reach is one of the first things I look for in a bird photography setup.

Birds are small, unpredictable, and often need space. Getting physically closer isn't always possible, and more importantly, it isn't always something we should be trying to do.

With a 600mm equivalent field of view available immediately, I could maintain distance and still create useful photographs of the birds I encountered.

That became one of my favourite parts of using the RX10 V.

Instead of thinking about getting closer, I could stop where I was, observe the bird, and use the camera's reach.

For birders who want photographs as a record of what they see, that combination is particularly useful.

Birding Versus Bird Photography

There is a distinction here that became important during my testing.

Birding with a camera and going out specifically to create bird photographs are not always the same thing.

Sometimes the photograph is documentation.

You want a clear image of a bird you encountered. Maybe it helps confirm an identification. Maybe it's a species you've never photographed before. Maybe you simply want a visual record of a great morning outside.

Other times, the photograph itself is the entire objective.

I'm waiting for a bird to fly.

I'm looking for a very specific wing position.

I'm photographing a kingfisher exiting the water.

I'm working in difficult light and pushing shutter speeds as high as possible.

Those situations place very different demands on a camera.

For the first category, I thought the RX10 V was fantastic.

Autofocus and Bird Recognition

The RX10 V also inherits some of the technology that has become increasingly important in Sony's larger Alpha cameras.

Its Real-time Recognition AF can recognize a variety of subjects, including a dedicated Bird setting, and the camera uses a BIONZ XR processor alongside a dedicated AI processing chip.

For a birding walk, this is a major advantage.

Birds don't normally sit against perfectly clean backgrounds. They're partially hidden by branches, surrounded by leaves, hopping through grasses, or appearing for only a few seconds before disappearing again.

Being able to let the camera help recognize the subject meant I could spend more time concentrating on composition and what the bird was actually doing.

It made the RX10 V feel much closer to the experience of using a modern Alpha camera than I expected from an all-in-one camera.

The Image Quality Surprised Me

The other question I had going into the test was image quality.

The RX10 V uses a 20.1-megapixel 1.0-type Exmor RS stacked backside-illuminated CMOS sensor.

I'm accustomed to larger sensors and some extremely high-end wildlife equipment, so I wasn't expecting this camera to replace those systems.

That wasn't really the point of the test.

What surprised me was how good the photographs looked for what the camera is designed to do.

Feather detail was good, colours looked great, and when I had decent light and a cooperative bird, I came away with files I was genuinely happy with.

And that is ultimately what matters.

I wasn't looking at the photographs afterward thinking, this is good for an all-in-one camera.

Some of the images were simply good photographs.

The Advantage of Having the Camera With You

There is another advantage to a camera like this that doesn't appear on a specification sheet.

You are more likely to bring it.

A 600mm lens is only useful if you're willing to carry it.

There are plenty of days where I am specifically going out to photograph wildlife and have no problem bringing a large professional setup.

But there are also hikes, walks, scouting trips, vacations, and casual birding days where carrying that much equipment changes the experience.

The RX10 V occupies an interesting middle ground.

You still have a real camera in your hands.

You still have a viewfinder.

You still have RAW files and manual exposure controls.

You still have modern subject recognition.

And somehow you also have the equivalent of a 24–600mm lens attached to it the entire time.

That is a pretty compelling combination.

When a Bird Suddenly Appears

The huge zoom range also solved a problem that happens constantly when photographing wildlife.

You don't know where the next subject will appear.

A bird could be 50 metres away one moment and another could land almost beside you seconds later.

With a large prime lens, that can become frustrating very quickly. Even with my usual 200–600mm, there are situations where 200mm is simply too tight.

The RX10 V starts at 24mm.

That means the same camera I was using to photograph a distant bird could immediately photograph a wider environmental scene.

For walking and exploring, I loved that flexibility.

Where My Larger Wildlife Cameras Still Have the Advantage

A Different Kind of Wildlife Camera

After a couple of days with the RX10 V, I stopped thinking about it as a smaller substitute for my normal setup.

It made more sense as its own kind of camera.

If I'm heading out specifically to spend six hours trying to capture one difficult bird-in-flight photograph, I'm still going to reach for my dedicated wildlife equipment.

But if I'm going for a birding walk?

That's where the RX10 V becomes really interesting.

One camera gives me everything from 24mm to 600mm.

I can photograph the landscape, a bird in its environment, a small bird high in a tree, and something completely unexpected along the trail without changing a lens.

And I can do all of that without carrying a huge amount of equipment.

Who I Think the RX10 V Is For

I think there are several types of photographers for whom this camera makes a lot of sense.

Someone getting more serious about birding who doesn't want to immediately build an interchangeable-lens system could have an enormous amount of capability in one camera.

A traveller could carry one camera instead of multiple bodies and lenses.

A birder primarily interested in identifying and documenting species gets that incredibly useful 600mm equivalent reach while maintaining distance.

And even experienced photographers may find it interesting as a lightweight camera for scouting, hiking, travelling, or days when photography isn't the only objective.

Sony has also given it considerably more capability than simply being a long-zoom compact. Alongside its bird and animal recognition, the RX10 V can shoot up to 30 fps and record 4K at up to 120p, although 120p uses a narrower angle of view.

What Surprised Me Most

I expected the 600mm reach to be useful.

I expected the camera to be lighter than my normal equipment.

What I didn't expect was how much those two things together would change the way I approached the walk.

I wasn't carrying photography equipment and then going birding.

I was simply walking with a camera.

When something appeared, I had 600mm available.

When I wanted to show the environment, I had 24mm available.

And when nothing was happening, I wasn't carrying a giant lens around waiting for something to happen.

That simplicity may be the RX10 V's greatest strength.

Conclusion

After testing the Sony RX10 V over a couple of days, I came away thinking that this could be a really interesting camera for birders.

The 24–600mm equivalent lens is the obvious headline, but the combination is what makes it work: long reach, an all-in-one design, good image quality, modern bird recognition, and a camera that is easy to carry for an entire walk.

For my most demanding bird photography, especially fast action where I want the greatest possible control, my larger Alpha bodies and dedicated telephoto lenses still have advantages.

But that's not necessarily the comparison that matters.

The RX10 V made bird photography accessible in a different way.

I could walk farther, carry less, maintain my distance from wildlife, and still have 600mm available whenever a bird appeared.

Sometimes the best camera for a birding walk isn't the camera capable of doing absolutely everything.

It's the one you actually want to carry for the entire walk.
