How to choose the right digital camera
There is always a new camera on the market, and the “best” model changes every few months. Rather than chasing the newest release, start with what you will shoot, then work out the camera type, the system and the budget that suit you.
1. Decide what you will shoot
Think about your most common subjects. Travel and everyday snapshots suit a compact camera. Portraits, events and landscapes usually need a larger sensor and a choice of lenses, which points to a mirrorless or DSLR system. Video creators should check autofocus, microphone input and stabilisation. Our compact cameras post covers the simpler end, and the flip-screen cameras post covers vlogging-friendly models.
2. Choose the camera type
Compact cameras are small and simple. Mirrorless cameras are smaller than DSLRs with a similar sensor, and they offer a live preview and electronic viewfinder. DSLRs use an optical viewfinder and have a long track record of lenses. Browse our Mirrorless Cameras Guide and DSLR Cameras Guide to compare the models we cover.
3. Think about the lens system
The camera body is only part of the cost. Lenses often cost more than the body and last longer, so choose a mount that has the lenses you are likely to need. Check the range of lenses available for the mount before you buy a body. Our Canon EOS Compared guide shows how the Canon range fits together.
4. Check sensor size and image quality
Larger sensors generally give better low-light performance and more control over depth of field. Full-frame sensors are the largest common option, APS-C sensors are smaller and cheaper, and compact cameras have much smaller sensors. Megapixel count matters less than sensor size and the quality of the lens.
5. Test the autofocus and handling
Autofocus speed and reliability matter most for moving subjects such as children, pets and sport. Handle the camera in a shop if you can. Check that the grip fits your hand, the buttons are where you expect, and the screen or viewfinder suits how you shoot.
6. Plan for batteries and storage
Battery life varies widely, and heavy use of the screen, video or Wi-Fi drains it quickly. Budget for a spare battery, and check the battery and memory card types before you buy. Our batteries guide and memory card guide cover the options in more detail.
7. Set a realistic budget
Include the lens, battery, memory card, bag and any filters in your total cost, not just the body. Compare prices from several sellers, and check whether the price includes a warranty.
8. Consider a used or refurbished camera
Refurbished and pre-owned cameras can offer good value if they come from a reliable seller with a clear returns policy. Check the condition, the shutter count if it is available, and whether the warranty still applies. Our Canon refurbished cameras guide sets out the checks in more detail.
9. Read reviews and try before you buy
Reviews show how a camera performs in real use, while specifications only tell part of the story. Read two or three reviews from different sources, and look at sample images. If you can, handle the camera and take a few test shots before you commit.
Common mistakes to avoid
Buying the newest model without checking the lens range, paying for features you will not use, and ignoring the cost of accessories are the most common mistakes. Another is choosing a camera based on megapixels alone. A larger sensor with a good lens usually gives better pictures than a higher megapixel count on a small sensor.
Many buyers also forget the weight. A body and lens you will not carry is a camera you will not use, so think about how you will carry it on trips and everyday outings.
Quick checklist
Decide your main subjects, choose the camera type, check the lens range, pick a sensor size that matches your needs, test the autofocus and handling, budget for accessories, and buy from a seller with a clear warranty and returns policy.
