The podcast compares the two popular types of cameras, DSLR and mirrorless cameras, and highlights the key differences between them. It explains that a DSLR camera uses a mirror to reflect light from the lens into an optical viewfinder, while a mirrorless camera uses a digital sensor to capture light and sends a live preview of the image to an electronic viewfinder or rear LCD screen. 

The podcast points out the pros and cons of each type of camera, such as DSLR cameras being better for fast-moving subjects and low-light situations, while mirrorless cameras are more compact and lightweight, and great for video recording. 

It also mentions that while both types of cameras are capable of producing great images, the decision ultimately comes down to personal needs and preferences. The podcast  concludes by noting that mirrorless cameras are considered to be the future of photography, and many professionals are switching to mirrorless cameras.
