Buying a digital camera in 2026 usually means choosing a mirrorless system, since DSLRs have mostly been phased out by the major brands. This guide walks through sensor sizes, the difference between mirrorless and older camera types, and which models in our range suit different budgets and uses, so you can buy with confidence rather than guessing at spec sheets.

Mirrorless vs DSLR vs Compact: Which Type Suits You

Mirrorless cameras have replaced the DSLR as the default choice for anyone stepping up from a smartphone. Without a mirror and optical viewfinder, mirrorless bodies are smaller, focus faster in most conditions, and give a live preview of exposure and colour before you shoot. Canon, Sony, and Nikon have all shifted their new lens development to mirrorless mounts, so a mirrorless body bought today has a long runway of future lenses and accessories.

Compact point-and-shoot cameras still have a place for people who want something pocketable with a proper sensor, better than a phone in low light or with zoom reach, without the bulk of interchangeable lenses. A DSLR is really only worth considering secondhand now, since new DSLR development has largely stopped across the industry.

Sensor Size and Why It Matters

Sensor size is the single biggest factor in image quality, low-light performance, and price. The two sizes you will see across our mirrorless range are APS-C (crop sensor) and full-frame.

APS-C (Crop Sensor) Mirrorless

APS-C sensors are smaller than full-frame, which keeps bodies and lenses lighter and more affordable while still offering a big step up from a phone or compact. The crop factor also gives extra reach for wildlife and sports, since a 150mm lens behaves more like 240mm on an APS-C body.

The Canon EOS R7 with RF-S 18-150mm lens pairs a 32.5MP APS-C sensor with up to 30fps continuous shooting, aimed squarely at sports, birding, and action work where reach and speed matter more than ultimate low-light performance.

Full-Frame Mirrorless

Full-frame sensors are roughly 2.5 times larger in surface area than APS-C, which translates into cleaner high-ISO files, shallower depth of field, and generally better dynamic range. They cost more, and so do full-frame lenses, but they are the standard choice for professional and serious enthusiast work.

The Canon EOS R8 is Canon's lightest full-frame body, built around a 24.2MP sensor with 4K 60p video, and is a common recommendation for someone upgrading from APS-C or a phone who wants full-frame image quality without a heavy kit.

At the top of the Canon range, the Canon EOS R5 Mark II uses a 45MP back-illuminated stacked sensor and supports up to 8K RAW video, aimed at working photographers and videographers who need resolution and speed in one body.

On the Sony side, the Sony Alpha A7 V brings a full-frame Exmor RS CMOS sensor and AI-enhanced autofocus modes to Sony's long-running A7 line, and is worth cross-shopping against the Canon options if you are not already invested in a lens system.

Canon or Sony: Does the Brand Matter?

Once you already own a lens or two, staying within that lens mount usually matters more than brand loyalty. If you are starting from scratch, Canon's RF mount and Sony's E mount both have mature lens lineups in NZ, and the deciding factor often comes down to ergonomics, menu layout, and which brand's colour science you prefer straight out of camera. For a closer look at Canon's camera range specifically, including how the EOS R body naming works, see our Canon NZ brand guide.

Other Buying Criteria Beyond Sensor Size

Sensor size and resolution are only part of the picture. A handful of other specs are worth checking on any camera's product page before you buy.

Autofocus: Many recent mirrorless bodies include AI-assisted subject detection for eyes, faces, and sometimes animals or vehicles, which matters if you shoot people, pets, or fast action. Autofocus behaviour varies by model and firmware version, so check the specific autofocus modes listed on each product page rather than assuming every body in a range performs the same way.

Image stabilisation: Many mirrorless bodies include in-body image stabilisation (IBIS), which helps with handheld shooting in low light and smooths out handheld video. Not every model includes it, and the amount of stabilisation varies by body, so check the spec sheet if this matters for your shooting style.

Video resolution and frame rates: If you shoot video as well as stills, check the maximum resolution (4K or 8K) and frame rate a body supports, along with whether its highest frame rates require a cropped sensor area. Higher frame rates at full resolution are generally reserved for higher-end bodies.

Lens availability: A camera body is only as good as the lenses available for its mount. Canon's RF mount and Sony's E mount both have broad native lens ranges in NZ across zooms, primes, and macro options, though availability for any specific lens is worth checking before buying a body with a particular kit in mind.

Battery life: Mirrorless bodies generally get fewer shots per charge than DSLRs did, since the electronic viewfinder and rear screen draw power constantly. Rated shots-per-charge figures vary significantly by model, so if you shoot all day without access to charging, check the manufacturer's CIPA rating for the specific body and budget for a spare battery regardless.

Comparing the Range

Who Should Buy Which Camera

If you are moving up from a phone and want the biggest jump in image quality without spending a fortune, the Canon EOS R8 is the easiest recommendation in this range. If your subjects move fast, whether that is sport, kids, or birds in the garden, the extra reach and frame rate of the Canon EOS R7 kit will matter more than sensor size. Anyone shooting client work, weddings, or serious video should look at the Canon EOS R5 Mark II or the Sony Alpha A7 V, both of which are built for professional workloads rather than casual use.

Compact Cameras: A Note on Current Stock

For anyone after a true pocket compact rather than an interchangeable-lens system, our Canon PowerShot G7 X Mark III is between stock at the moment. Check back on the Digital Cameras collection or get in touch and we can let you know when it is back in.

Budgeting for Accessories

A camera body is rarely the full cost. Budget for at least one extra battery, a fast SD card rated for 4K video if you plan to shoot footage, and a tripod if you shoot landscapes, video, or long exposures. Our Storage & Memory collection covers memory cards suited to mirrorless bodies, and the Audio, Photo & Video collection covers tripods and other camera accessories.

Frequently Asked Questions

What's the difference between a mirrorless camera and a DSLR?

A mirrorless camera has no internal mirror or optical viewfinder, using an electronic viewfinder or the rear screen instead. This makes the body smaller and generally allows faster, more accurate autofocus, which is why every major manufacturer has moved new lens development to mirrorless mounts.

Do I need a full-frame camera, or is APS-C enough?

APS-C is enough for most hobbyists and even many professionals, and it costs less for both bodies and lenses. Full-frame is worth the extra cost if you regularly shoot in low light, want the shallowest possible depth of field, or need the dynamic range for heavy editing.

Which Canon mirrorless camera is best for beginners in NZ?

The Canon EOS R8 is a common beginner-to-enthusiast recommendation because it puts a full-frame sensor in a lightweight, relatively affordable body. If your budget is tighter or you shoot a lot of fast action, the APS-C Canon EOS R7 kit is worth comparing.

Can I use my old Canon EF lenses on a Canon EOS R camera?

Many EF and EF-S lenses work on Canon's RF-mount EOS R bodies with an EF-EOS R mount adapter, though specific compatibility and autofocus behaviour can vary by lens, so check compatibility on Canon's own lens compatibility page before assuming a lens will work exactly as it did on your old body.

How much should I budget for a mirrorless camera kit in NZ?

Body-only mirrorless prices in this range start from around $2,600 to $2,700 for an entry-level full-frame or APS-C kit body, rising to $7,000 or more for professional bodies like the Canon EOS R5 Mark II. Add roughly $150 to $400 more for a spare battery, memory card, and a basic tripod.

The Bottom Line

For most people upgrading from a phone or an old compact, the Canon EOS R8 offers the best balance of full-frame image quality and price. Sports and wildlife shooters should look at the APS-C Canon EOS R7 kit for the extra reach and speed, while working photographers and videographers will get more out of the Canon EOS R5 Mark II or Sony Alpha A7 V.
