The W80 was manufactured 11 years earlier than the A7R IV and that is quite a big gap as far as technology is concerned. Both cameras offer different body type with the Pentax W80 being a Compact camera and the Sony A7R IV being a SLR-style mirrorless camera.

Before diving in to a in-depth comparison, below is a quick highlight of how the W80 grades vs the A7R IV when considering portability, imaging, features and an overall rating.

Here is a sample of the gallery pictures for Pentax Optio W80 and Sony Alpha A7R IV. The entire galleries are available at Pentax W80 Gallery and Sony A7R IV Gallery.

Typically, its difficult to visualise the gap between sensor sizing purely by reviewing a spec sheet. The photograph underneath should give you a stronger sense of the sensor sizing in the W80 and A7R IV.

Clearly, both of those cameras offer different resolutions and different sensor sizing. The W80 featuring a tinier sensor will make shooting bokeh harder and the Sony A7R IV will deliver greater detail due to its extra 49MP. Greater resolution will help you crop pics a little more aggressively. The older W80 is going to be disadvantaged in sensor innovation.
