Olympus Pen E-P1 Review at TrustedReviews – Cliff Smith concludes:
The Olympus E-P1 is an interesting and innovative camera, and as a first model in what will probably be a series it has some very nice features. Build quality and finish are of an exceptionally high standard, and image quality and performance are safely superior to the vast majority of compact cameras. However the enormous cost compared to a good DSLR, and the lack of either a viewfinder or built-in flash will put many people off.
Cliff gave the E-P1 an overall rating score of 7/10.
