Porro prism binoculars provide a 3d effect that many individuals find superior. They also tend to produce better apparent centerfield sharpness I believe simply because of the simplicity of the porro prism design.Having said that many folks argue that roof prisms are inherently more durable and also point out their increased level of waterproofness. Optically I think many of the inexpensive roofs are catching up to the inexpensive porros but aren't quite there yet. The argument that you need to spend 3x the cost of the porro to get an equivalent image quality roof prism binocular may or may not still be true. I think they jury is out on that one.For what it is worth any of the binoculars being discussed so far are sure to please a majority of the individuals out there.</blockquote>
