Sensor size is important when choosing a digital camera, and the two main options you’ll come across are full frame sensors and APS-C sensors.There are key differences between the two and each has its own advantages, so which one you choose depends on your photography needs and budget.

AI and machine learning are making digital cameras smarter and easier to use, with more precise autofocus, eye and subject tracking/ recognition, as well as more advanced editing software that can adjust colour and contrast and better organise images.

Conversely, it’s interesting to see some more traditional photography methods making a comeback on modern digital cameras, such as manual focus, hybrid viewfinders (optical and electronic), dial-based controls, and cool retro designs.

Full frame

APS-C

A full frame sensor is the same size as a full frame of old school 35mm film, giving photographers and videographers better image clarity, depth and detail, as well as more of the image to work with when composing a shot and cropping when editing.

APS-C stands for Advanced

Full frame provides a shallower depth of field for portrait photography, drawing attention to a subject’s face and expression, and a wider field of view when shooting landscapes. Bokeh is better with a full frame camera, because a shallower depth of field creates a smoother background blur, making the subject more distinct in the foreground. Cameras with full frame sensors tend to be larger and more expensive than those with APS-C sensors. Professional photographers favour the full frame format for its higher image resolution, compatibility with specialised lenses, wider field of view, and greater ISO for low light performance.

Crop factor is a term you’re likely to come across when considering a camera with an APS-C sensor. Simply put, because the APS-C frame is smaller than a full frame sensor, a smaller part of the scene is captured, and the image resembles a shot that has been zoomed in. Cropping makes subjects appear larger and closer, which is useful when shooting from a distance, and it also eliminates the need to manually crop images when editing. What is crop factor?
