I like the DianaF+ a great deal and am pleased with the results I get from taking photos with it. In fact, I prefer the DianaF+ over my Holga. The DianaF+ is particularly effective when using the flash. It creates an interesting and artistic vignette that is very cool. I particularly like the "retro" design.
My 4 star rating is based on two things: 1) In my opinion, it's pricey for a plastic camera. And 2) I can't get the lens to remove for pinhole shooting. It just won't come off.
