When you start looking into buying a new digital camera, it's easy to feel overwhelmed by the sheer volume of features and specifications on offer. Understanding the key ones will help you find the right camera for your style of photography.

One feature that experienced photographers take seriously is autofocus performance. But what exactly is it, why does it matter, and when might you want to use manual focus instead? Let's break it down.

What is Autofocus?

In every image there's a subject — one you'll want rendered in sharp focus. Focusing a camera lens involves physically shifting lens elements until the clearest image of your subject is achieved. These adjustments depend on the distance between your subject and the camera, and even the smallest shift can make a significant difference to sharpness.

Autofocus (AF) automates this process. The camera and lens work together to make these adjustments when you half-press the shutter release button, or when you press a dedicated back-button focus control.

Autofocus vs. Manual Focus: What's the Difference?

As the name suggests, manual focus requires you to physically adjust the focus of your lens — typically by turning a focus ring on the barrel — until your subject appears sharp. While autofocus handles this automatically, manual focus puts you in complete control of what's in focus and to what degree. To go deeper on technique, settings, and when to reach for it, read our full guide to manual focus photography.

Autofocus is fast and reliable for most shooting situations. Manual focus, on the other hand, gives you creative precision — particularly useful in scenarios where the camera might struggle to determine exactly what you want sharp.

AF Systems, Points & Modes Explained

Many photographers are happy with a basic understanding of autofocus, but if you want to make more informed purchasing decisions, it helps to understand the common AF terminology:

• Contrast Detection AF — Simple and effective. The system looks for contrast at the edges of a subject and adjusts the focal point until contrast is at its sharpest.
• Phase Detection AF — Light coming off a subject is measured to determine distance, and the lens adjusts accordingly. Generally faster and more accurate than contrast detection, particularly for moving subjects. Most modern mirrorless cameras use on-sensor phase detection. If you're new to mirrorless systems, our guide to how mirrorless cameras work explains the technology in plain language.
• Focus Points — These are the points within the frame where the camera can achieve focus. Modern cameras typically offer a large number of focus points — often covering the majority of the frame — making it easier to place focus exactly where you need it. Cross-type points provide the most accurate autofocus performance.
• Single AF (AF-S / One-Shot) — The lens focuses once when you press the shutter, then locks. Best for stationary subjects.
• Continuous AF (AF-C / AI Servo) — The camera continuously adjusts focus as a subject moves. Essential for action, sports, and wildlife photography.

Why Would Anyone Use Manual Focus?

While autofocus is fast and accurate in most conditions, there are situations where manual focus is the better choice:

• Low light conditions — In dim environments, autofocus systems can hunt and struggle to lock on. Your eye will often do a better job of determining what's sharp.
• Macro photography — At very close focusing distances, depth of field becomes extremely shallow. To understand why this matters so much, it helps to read up on how depth of field works in photography. Even a tiny shift in focus can dramatically change the result, and manual focus gives you the precision to place focus exactly where you want it.
• Creative control — Sometimes you want to focus on something the camera wouldn't naturally prioritise — manual focus lets you make that call.

So, Is Manual Focus Better Than Autofocus?

For most photographers, autofocus is the better choice most of the time. Modern AF systems — particularly the phase detection systems found in current mirrorless cameras — are fast, accurate, and reliable across a wide range of conditions. If you're ready to find a camera with excellent autofocus performance, our roundup of the best digital cameras for photography in Australia is a great place to start. If you're shooting sport, wildlife, events, or everyday photography, autofocus will almost always outperform manual focus in speed and consistency.

That said, manual focus is the better option in specific scenarios: macro photography, low-light shooting, or situations where you need precise creative control over what's sharp. The honest answer is that neither is universally superior — the best photographers know when to use each. For most buyers, prioritising a camera with strong autofocus performance is the right starting point.

Manual Focus Lenses vs Autofocus Lenses

Beyond technique, there's a practical product distinction worth understanding: manual focus lenses and autofocus lenses are different pieces of hardware. Autofocus lenses contain a built-in motor that drives focus automatically when paired with a compatible camera body. Manual focus lenses have no such motor — focus is adjusted entirely by hand via the focus ring.

Many photographers deliberately choose manual focus lenses for their optical quality, compact size, or lower price point — particularly older legacy glass adapted to modern mirrorless mounts. If you're considering manual focus lenses, check compatibility with your camera system before purchasing. Our team at Novatech Direct can advise on adapters and compatible options across Canon, Sony, Nikon, and Fujifilm systems.
