The age-old question of whether great images are made by the photographer or the camera is a boring one. However, a more interesting topic is the gap between high-end cameras and entry-level cameras and whether most people can tell the difference.
The answer to whether gear matters is generally, "yes a bit, but it depends what you're shooting." Some shots, particularly beauty with front-to-back focus and proper lighting like in this video, have negligible gains from increasing the quality and price of the gear used. That's not to say there's no difference, I — like many of the people who will watch this — could instantly tell which camera took which image, but the difference is patently not large. This is exacerbated by viewing the images on YouTube or social media which goes through compression.
What is interesting about comparisons like this, to me at least, is how narrow the gap is getting between expensive and cheap cameras. The higher-end is experiencing diminishing returns, whilst the lower end is replicating high-spec features at a lower cost. What cannot be replicated, however, at least currently, is the versatility of the best gear. For example, the Sony ZV-1 (the cheap camera in this video) isn't going to perform as well as the Sony a7R IV (the expensive camera in this video) in a great many situations (think low light or any scenario that requires a different lens!) Nevertheless, it does show how good the ZV-1 is for the right purposes.
