noticeable overall? I wanted to print a couple images 2 feet x 2.5 feet. When i take photos i feel i do a pretty good job because i always use a tripod making sure it's steady, take concern for lighting, and take many pictures at different angles and distances away from an object or view to ensure a good photo. I don't know much camera vocab so here is a link to a comparison
