The best DSLR cameras don’t just produce the best pictures of any type of camera, they also open up the door to more creative photography, with all controls for focus, aperture, shutter speed, ISO and white balance at your fingertips. They give you the choice of trusting the camera’s automatic settings or taking full manual control when you need it.
Whether you’re looking for a top-of-the-range model or an entry-level DSLR, there are plenty of other options available, such as a compact system camera (CSC). Similar to DSLRs, they offer the ability to change lenses, more flexibility when capturing a shot and in some cases, are cheaper alternatives to a DSLR.
However, while the best models have intuitive controls, great handling and produce the pictures of your dreams, the worst suffer from poor design, cheap build quality or bad battery life. We test dozens of DSLRs every year, so take a look at our DSLR Best Buys, to discover the models that Which? recommends.
Buying the best camera for you
Before you head to the shops to purchase a new camera, take a look at our interactive choosing tool below. This tool will help you decide between a compact system camera or a digital SLR camera, with advantages and disadvantages of both types.
What makes a good DSLR camera?
Thanks to our rigorous lab testing, we’re uniquely placed to offer you our essential DSLR camera buying tips, as well as assessing the key pros and cons of owning a DSLR camera.
- Superior image resolution means professional photos - the larger body of a DSLR means it can house a bigger image sensor than both compact and bridge cameras. The best DSLRs have sensors featuring 24Mp or more, meaning they can capture a huge amount of photographic detail.
- ISO range - the ISO value of a DSLR or CSC camera determines how sensitive the sensor is to light. A higher ISO range of 1600 and upwards is particularly useful when taking night photography, or shooting in low-light conditions, as it will allow you to capture more light.
- Interchangeable lenses make for more creative shots - most budget-level DSLR and CSC cameras come with a starter 'kit lens'. Frequently, this will be an 18-55mm lens as this is the normal focal length for DSLR cameras. By buying different camera lenses, such as a wide-angle or fisheye lens, you’ll achieve different effects in your shots.
- Image stabilisation negates any blur - if you’ve got a shaky grip on your camera, image stabilisation in a DSLR will counteract photo blur. Because image stabilisation is often built into the lens, it’s a lot more effective when compared with compact digital cameras.
- Weatherproofing comes as standard - the majority of DSLRs are weatherproofed, making them resistant to conditions such as rain and snow, as well as protecting the internal parts from dust and moisture.
How much should I spend on a DSLR?
DSLRs cost anywhere from around £300 for the most basic, entry-level model to £1,600 or more for high-end cameras. Our Best Buy DSLRs range from £350 to an eye-watering £2,000, although that buys you the kind of camera that the professional photographers aspire to.
What type of interchangeable lens camera should I buy?
If you want a little more finesse from your photos, then it’s worth investing in a DSLR or compact system camera (CSC). With a big sensors and the ability to switch between lenses, these models can capture a lot more detail than a standard digital camera.
- Compact System Camera (CSC): This type of camera is ideal for anyone wanting to jump up a level from a simple point-and-shoot camera, but without getting struck down in settings and menus. They offer similar photo and video quality, but they are smaller and easier to use.
Pros: Almost as slim as a compact camera, generally less expensive than DSLRs, plus more scene modes and automatic settings.
Cons: Some models lack a viewfinder, fewer quick-access dials and buttons.
Buy if: Interchangeable lenses are a must, but DSLRs are too bulky.
- Digital Single-Lens Reflex Camera (DSLR): Used by professionals and amateur photography enthusiasts alike, a DSLR camera is the best option if you want high-level control over your photos. You can use different lenses to create different effects, for example, pick a wide-angle one for landscapes or a macro lens for extreme close-up shots.
Pros: Optical viewfinder, adjust shutter/aperture/ISO and white balance levels, better image quality than a compact or bridge camera.
Cons: Bulky size, flagship models have a high price tag, changing lenses can sometimes be a hassle.
Buy if: Only the best photo and video quality will do.
DSLR Vs Compact system cameras (CSC) - key differences
Slimline vs chunky design - DSLRs contain a mirror and a prism (similar to how a periscope works) to view a more accurate image that the charge-coupled device (CCD) will capture, but a CSC doesn't use a mirror (this is why sometimes they're referred to as a 'mirrorless' camera). Some photography purists argue the mirror in DSLRs makes for more detailed photos, but our expert test lab doesn’t agree. Both types of camera have received numerous Best Buy awards. Since CSCs don’t use a mirror to take photos, they’re a lot slimmer and more portable than DSLRs.
Bigger sensor, better photos - Generally speaking, cameras with a big sensor take better photos. This is because they can capture more scenery and greater detail in low light. If picture quality is paramount to you, then you will want to shop for a DSLR with an APS-C or an even larger Full-Frame-sized sensor. CSCs predominantly rely on APS-C sensors or a smaller Micro Four Thirds sensor, however, there are full-frame models available now as well.
CSCs are cheaper, DSLRs more premium - Although features such as wi-fi, tilting displays and 4K video recording are just being introduced to DSLRs, they’ve been available for some time now CSCs. These cameras start at £200 and tend to offer more features for less money, whereas DSLRs are available from £300 and concentrate on offering a more premium experience.
Electronic viewfinder means increased accuracy - If a CSC does have a viewfinder, typically it will be electronic (EVF) instead of optical (OVF). An EVF is essentially a tiny LCD screen. You use it just like an OVF, and what you see is what you get with an EVF: they show exactly what the lens sees, provide 100% coverage, and there’s no guesswork how an image will turn out before you’ve taken a photo. One noticeable downside is that it can mean a lag between the scene in front of you and that shown in your viewfinder. As well as not suffering from this lag, optical viewfinders in a DSLR show around 96-97% of the entire photo you’ll capture - instead of the 100% preview you’ll get with a CSC.
