However, DSLRs are increasingly challenged by mirrorless cameras, which are lighter and more compact. For instance, the Canon EOS 6D Mark II weighs about 3.44 lbs, highlighting the bulkiness of DSLR systems compared to their mirrorless counterparts [14].

Mirrorless Camera Advantages

Mirrorless cameras have gained popularity by solving some of the size and speed issues associated with DSLRs. Here’s a breakdown of how they compare:

"The RF mount has been designed with an eye to the future, such as improving communication speed between camera and lens and adding extra contacts to support more functions. For example, with the RF mount, one of the benefits of high-speed communication between the lens and the camera is that when you have optical problems like diffraction and aberration, we can do in-camera correction of those in real-time. This instant processing means you're getting better image quality straight out of the mirrorless cameras."
– Mike Burnhill, Canon Europe Senior Product Specialist [14]

Improved Workflow for Photographers

These hardware advancements have made workflows more efficient. Wildlife photographer Dani Connor highlights one of the key benefits:

"If I need to react quickly when photographing wildlife, or maybe the light is constantly changing, with a mirrorless camera I can quickly adjust my ISO or my shutter speed and I can see what my photo will look like, without having to take my eye from the viewfinder." [14]

Here’s a quick look at some popular mirrorless camera models and their prices:

• Sony Alpha 9 III: $5,999.00

• Nikon Z9: $5,496.00
