Just a comment about the the Pentax WP readers review, the second entry starts with ” I purchased the non waterproof version… (S5i)”
There is very little in common between the two models, the WP is a made by Sanyo using the Minolta folded optics design, the S5i is assembled by Pentax with Casio and Sony parts and a Pentax lens.This is a common misconception that because two products are sold under the same brand are the same or similar.
