A mirrorless camera gives you plenty of room to grow, whether you are learning the basics, getting more serious about photography, or shooting professionally. With interchangeable lenses, responsive autofocus and strong photo and video features, mirrorless cameras have become a popular choice for all kinds of shooters.
digiDirect stocks everything from beginner-friendly APS-C models to compact Micro Four Thirds options and professional full-frame systems. You can also browse the wider range of cameras to see which type feels right for the way you like to shoot.
How Does a Mirrorless Camera Work?
Understanding what makes a camera mirrorless can make the differences between camera systems much clearer.
Unlike a DSLR, a mirrorless camera does not use a mirror box to direct light into an optical viewfinder. Light reaches the image sensor directly, with the scene displayed on the rear screen or electronic viewfinder.
Removing the mirror mechanism can reduce body size and weight. It also allows autofocus coverage across more of the frame, a live preview of exposure settings and silent shooting on compatible models.
Choose the Right Mirrorless Sensor Format
Sensor size affects low-light performance, depth of field, body size and lens options. The best format depends on what you photograph and how much gear you want to carry.
Full Frame
Full frame cameras offer strong low-light performance and greater control over shallow depth of field. They suit enthusiasts and professionals working across portraits, events, landscapes, sport and video.
APS-C
APS-C cameras balance image quality, portability and price. They are a practical choice for beginners, travel photographers, enthusiasts and creators who want an interchangeable-lens system without the size of many full-frame setups.
Micro Four Thirds
Micro Four Thirds cameras use a smaller sensor that can support compact bodies and lenses. They suit travel, wildlife, and video shooters who place a high value on portability.
Features to Compare Before You Buy
Mirrorless cameras vary widely in features and performance. Focus on what will affect the way you actually shoot.
- Autofocus: Look at autofocus coverage and subject detection for people, animals, vehicles or other subjects you regularly photograph.
- Image stabilisation: In-body stabilisation can reduce camera shake with compatible lenses.
- Burst rate: Faster continuous shooting can help with sport, wildlife and action.
- Viewfinder: Higher-resolution electronic viewfinders can provide a clearer view when composing shots.
- Video: Compare resolution, frame rates and recording limits if you shoot video.
- Card slots: Dual slots can provide extra storage or an in-camera backup on supported models.
Mirrorless or DSLR: Which One Suits You?
Both systems can produce excellent results. The better choice depends on your existing gear, budget and shooting preferences.
Mirrorless cameras tend to offer smaller bodies, broad autofocus coverage and strong hybrid photo and video features. DSLR cameras can offer longer battery life, an optical viewfinder and good value, particularly if you already own compatible DSLR lenses.
A DSLR can still make sense for photographers with an established lens collection or those who prefer traditional handling. Mirrorless is often the better fit when starting a new system or prioritising video and newer autofocus features.
Build Your Mirrorless Camera Kit
Choosing a camera body is only the start. Your lens mount determines which lenses fit natively, so check compatibility before buying.
Different manufacturers use different mounts for their mirrorless lenses. Lens adapters can make some older lenses compatible, although autofocus and other functions may vary.
Useful additions include fast memory cards, spare batteries, a camera bag and a tripod suited to your shooting style.
FAQs
Is a mirrorless camera better than a DSLR?
Mirrorless cameras often provide newer autofocus, video and electronic viewfinder features in smaller bodies. DSLRs can offer longer battery life and good value. The better choice depends on your photography and existing lenses.
Do I need full frame or is APS-C enough?
APS-C is more than capable for many photographers and can keep your kit smaller and more affordable. Full frame can provide stronger low-light performance and greater control over depth of field. Choose based on your needs rather than sensor size alone.
Can I use my existing DSLR lenses on a mirrorless body?
Often, but you may need a compatible lens adapter. Compatibility depends on the lens, camera mount and adapter. Some functions may also work differently from a native lens.
Why is mirrorless battery life shorter?
Mirrorless cameras rely on an electronic viewfinder or rear screen for composing images. These displays continuously use power while the camera is operating. Carrying a spare battery can help during longer shoots.
What memory card speed do I need for a mirrorless camera?
It depends on your camera and shooting settings. High-resolution bursts and high-bitrate video usually need faster sustained write speeds than everyday photography. Check your camera manufacturer's recommended card type and speed.
