Look Ma, no mirrors!

My new (mirrorless) weapons of choice.

From my first wedding photography gig as a second shooter in 2015 till end 2021 (a good six years), I was always using my trusty Canon 5D Mark III DSLRs. For the uninitiated, DSLRs are basically digital cameras with a mirror box in it and the mirror flaps up as you activate the shutter for the sensor to digitally ‘capture’ the image.

More recently, mirrorless cameras have been all the rage — they do not have any mirror box and the image is ‘captured’ by the sensor when the shutter is activated. Without the mirror box, the form factor of these cameras are smaller (and lighter) but this also means you need to switch on the camera to view the scene through an electronic viewfinder (EVF). DSLRs do not have an EVF and you can view the scene directly as the image is ‘shown’ to the user through a prism.

Sony was initially leading the charge in the mirrorless camera battle and pushing out countless models, until Canon and Nikon finally released more capable mirrorless cameras in recent years. After six years and countless events/wedding assignments, I decided to take the plunge and switch to mirrorless cameras, and these are my early thoughts and learnings.

1. Faster and more accurate autofocus system
