DSLRs vs MIRRORLESS

DUAL PIXEL PERFORMANCE

Like a dual carriageway for autofocus, Canon brings a speed boost

here’s a fundamental difference in the

way that DSLR and mirrorless digital

cameras autofocus. The reflex mirror

of an DSLR directs the image produced by the

lens to a dedicated phase-detection AF module,

as well as up into the viewfinder. This can work

out whether the lens’s focus distance is too

long or too short, and make the adjustments.

For mirrorless cameras, or when using an

DSLR in ‘live view’ or movie capture mode,

contrast-detection autofocus is the traditional

alternative. This adjusts the lens’s focus until

the greatest amount of contrast is registered

at a defined point or area in the scene.

All of Canon’s DSLR and mirrorless cameras

in this test group feature revolutionary Dual

Pixel AF. Each ‘pixel’ on the image sensor is

divided into a pair of photodiodes, enabling

phase-detection autofocus with excellent speed

and accuracy.

As usual, the Dual Pixel AF

system enables phase-detection

autofocus points across most of the

frame, in this case 5,565 of them.
