Compare The Best Nikon Digital CamerasApril 2019

There are four main camera types that you will need to decide between when choosing a new camera. Each have their own advantages and disadvantages and which one is right for you will depend on what type of photos you plan to take and what you aim to get out of your photography. Many people use a mobile phone as their camera these days, which is fine for day to day snaps but for quality photographs it's hard to beat a dedicated camera.

Compact Cameras

Compact cameras pack an incredibly large amount of technology into a tiny design that will easily fit inside your pocket. Compact cameras produce better quality images than mobile phones mainly because they have much bigger lenses which allow more light and more detail to be received by the camera's sensor. They also feature zoom lenses which let you get close to the action without any loss in image quality that comes with the digital zooms found on phones.

Lightweight and compact

Great for everyday use and holiday snaps

Better image quality than a smart phone because of bigger lens

Easy to use

Get close to the action with an optical zoom

Full exposure control often available

Cheap

Image quality generally lower than other camera types.

You can not change lenses

Compact cameras are ideal for everyday use, family holidays and trips where you don't want to be dragging a bulky and heavy camera around with you.

Bridge Cameras

Bridge cameras are designed to bring many of the features found on a DSLR camera, into an easy to use design. The often feature very powerful optical zooms that extend from very wide angle (which is great for architecture) to over 40x times zoom (which is ideal for wildlife and sport photography). They often feature an image stabiliser which will allow you to take photos with a long zoom without using a tripod.

Improved image quality

Bigger lens allows in lots of light for more detailed photos

Powerful optical zooms available

Many of the features found on a DSLR

Easy to use

Often has an image stabiliser

You can not change lenses

More bulky than a compact camera

Bridge cameras are great for those looking for something a bit more powerful than a compact camera, but don't want the complexity of a DSLR.

System Cameras

System cameras are similar to bridge cameras in that they offer many of the features found on a DSLR, but in a smaller and easier to use form. They differ from system cameras in that you can change the lens on a system camera, which gives you far greater creative control. Many different lens types are available from ultra zoom lenses that get really close to the action, to macro lenses which allow you to photograph small objects really close up.

Great image quality

Change lenses to suit your subject

Full frame sensors available providing very detailed photos

Lens adapters give you access to the huge range of Canon and Nikon lenses

Cheaper than a DSLR

Stylish

Can be expensive

Image quality is not as high as a DSLR

System cameras are ideal if you want the power of a DSLR with interchangeable lenses in compact size and at a cheaper price.

DSLR Cameras

Digital SLR cameras give you outstanding image quality through very high quality components, large image sensors and a great range of lenses. You have full creative control by being able to adjust every aspect of the camera's exposure settings. Optical viewfinders let you see exactly what the camera sees and make it much easier to frame the shot in bright sun light conditions.

Outstanding image quality

Full creative control of all exposure settings

Very wide range of lenses available

Optical viewfinder lets you see exactly what the camera is taking

Record RAW images for the highest possible image quality

Fast autofocus captures subjects that are moving quickly

Expensive

Bulky and heavy

May have no built in flash

Digital SLRs are a great choice for serious photographers who love taking photos and want the best possible image quality.

Image Sensors Explained

Megapixels & Sensor Size

Megapixels are a quick and easy way of measuring the level of detail that you can expect from a camera. One megapixel means 1,000,000 pixels and refers to the number of individual pixels that the camera's sensor can capture.

Whilst megapixels are a quick guide to the camera's performance, equally important is the physical size of the camera sensor. Larger sensors are able to capture more light which produces images with less noise and better dynamic range. Because they capture more light they can also take superior photos in low light conditions without flash.

Bigger sensors require physically bigger cameras and also bigger lenses to gather enough light to cover the sensor. For this reason the biggest sensors tend to found on the biggest cameras such as the DSLRs. This is also the reason why mobile phone manufacturers use very small sensor sizes.

The physical size of the sensor is described in many different ways including fractions and letters. Unfortunately it is not easy to relate these sizes to one another, but the chart to the left provides a guide and shows how each sensor size relates to the size of traditional 35mm film.

Full frame sensors are sensors that are physically the same size as traditional 35mm film. Full frame sensors are desirable because they capture very detailed images, but also because they are directly compatible with the huge range of lenses designed for 35mm film. There are plenty of DSLR cameras with sensors which are smaller than full frame. These cameras can still be used with 35mm lenses, but the smaller sensor size means that a conversion factor will apply to the lens. For example if a camera with non-full frame sensor has a conversion factor of 1.5 then a 200mm lens will behave like a 300mm lens, which is great if you want to be closer to the action, but not so good if you need a wide angle shot.

Optical vs Digital Zoom

Many cameras have incredible zoom capabilities which let you get really close to the action. However when checking a camera's zoom capability it's important to check whether it has an optical zoom, a digital zoom or a combination of both.

Digital zooms let you zoom in by effectively cropping the photo. They do produce a zoom effect, but the quality of the image will be reduced because it has been cropped. Most mobile phones use a digital zoom.

Optical zooms work by physically moving the lenses that capture the image. The zoomed in photo is still captured using the full extent of the camera's sensor so there is no loss in image quality as you soom in.

Camera Screens

Almost every digital camera has a built in screen which lets you frame the shot you are taking, review and edit photos that you have taken, and also adjust the camera settings. Some cameras have fold out screens which make it easy to take self portraits and allow you to take photos when the camera is not at eye level such as in a crowd.

Touchscreen camera displays offer very intuitive control systems similar to those found on a mobile phone. Touch allows you to choose which part of the picture you want to be in focus or to be exposed correctly simply by touching it.

Viewfinders

As digital screens have become more advanced many camera manufacturers have dispensed with the traditional camera viewfinder. However there are many advantages to a traditional viewfinder. Firstly it is much easier to see what you are photographing in bright sunlight conditions through a viewfinder. Holding the camera to your face also steadies the camera giving you sharper photos. Finally a viewfinder uses much less power than a screen so you can switch the screen off when taking photos to make your battery last longer.

Traditional cameras have optical viewfinders. This means that the image viewed through the viewfinder is exactly the same as the image that camera will photograph. Optical viewfinders reflect light entering the camera's lens off a mirror and into the viewfinder. When the photo is taken the mirror quickly flicks out of the way to let the sensor receive the image. All top end DSLRs have optical viewfinders. Some cameras have digital viewfinders which are basically a second very small screen viewed through the viewfinder. Digital viewfinders have the advantage of allowing you to preview how the fin
