How to choose your first camera

What is your phone missing?

Today's phones rival many cameras for landscapes and everyday photos taken in good light, and their processing makes dark scenes surprisingly bright. So before choosing a camera, write down what your phone cannot do. Running children or sports keep coming out blurred; distant birds or a stage look tiny; you want natural background blur; you want the feel of turning real dials and pressing a real shutter. The more specific your reasons, the clearer your criteria become.

What sensor size changes

The sensor is the plate that receives light and turns it into an image. With technology of the same generation, a larger sensor gathers more light per pixel, giving less noise in the dark, a wider range from bright to dark in one shot, and easier background blur. In exchange, a bigger sensor means a bigger, heavier body and lenses. The size of 35mm film, about 36 by 24 mm, is commonly called full frame, and smaller sensors are described by how much smaller they are than that. Phone sensors are far smaller than any of these.

• Large sensors: better in low light and for blur, but bigger and heavier
• Mid-size sensors: a balance of quality and size, common for beginners
• Small sensors: light, and long zoom lenses are easier to build

Equivalent focal length and crop

With a smaller sensor, the same lens effectively uses only the center of the image, so it looks narrower and more zoomed in. This ratio is called the crop factor, and for sensors a little smaller than full frame it is roughly 1.5 to 1.6. That means a lens with the same number shows a different field of view on different bodies, and product descriptions often list a full-frame equivalent as well. Compare those equivalent figures to avoid confusion. Small sensors have an edge for telephoto, while going wide needs shorter lenses.

Interchangeable lenses or a fixed lens

Interchangeable-lens cameras let you swap between wide, telephoto and bright prime lenses to suit the scene, which gives a lot of freedom. But every extra lens adds cost and weight, and dust can get in while you change lenses. Fixed-lens cameras are designed around their lens from the start, so they are smaller, lighter and easier to look after. Some cover a huge zoom range in one body, while compact ones concentrate on a single field of view. If you already know what you mainly shoot, a fixed lens can actually be more convenient.

Viewfinder and controls

A viewfinder is the window you put your eye to. In strong midday sun the rear screen is hard to see, but the viewfinder stays clear, and holding the camera against your face also reduces shake. A rear screen that tilts or swivels makes low angles and overhead shots easier. Dedicated dials for shutter speed and aperture let you change settings without digging through menus. These differences are felt far more when you hold the camera than when you read a spec sheet.

Weight and size decide in the end

Even a great camera is useless if it is too heavy and stays at home. One of the most common beginner stories is buying big gear for image quality and gradually going back to carrying only a phone. Judge the weight with the lens attached, and check whether it fits in the bag you carry every day. If you mostly plan to use it on trips and walks, lean toward small and light; if you shoot a lot near home or at events, lean toward image quality and handling.

The budget is more than the body

If you budget only for the camera itself, you will soon run short, because other things come with it. Prices change often, so think in terms of items rather than figures. Used or previous-generation models are often plenty for a beginner, but always check the shutter count, spots on the sensor, fungus or haze inside the lens, and whether a warranty is included.

• Lenses: you will soon want one more besides the kit lens
• Memory cards: video and burst shooting need fast write speeds
• Spare batteries: they often drain faster than a phone
• A bag, a strap and lens cleaning tools
• Storage space to transfer and keep your photos

Checklist before you choose

Answering the questions below narrows the options a lot. Fitting your actual use matters far more than any single spec number. If you can, hold and shoot with the camera in a store or rent one before deciding.

• What exactly can't your phone do?
• What will you mainly shoot: people, landscapes, motion, distant subjects or video?
• Are you willing to swap lenses?
• Is the weight with the lens something you would carry every day?
• Have you budgeted for costs beyond the body?
