Given its price, and the fact that it comes with an accessory flash, this Pentax is a strong competitor. In Pop Photo Lab tests, resolution proved comparable, but Pentax took the lead in noise and AF speed in moderate and bright light (except at EV 12, where they essentially tied). The Olympus E-620 rallied back in low-light AF, where it didn't slow as much as the Pentax, and in color accuracy, where it edged into our Excellent rating with an average Delta E of 7.9, compared with the Pentax's 8.3 (an Extremely High rating). If you've never been in live-view mode with a DSLR that has a swiveling, tilting LCD, you won't know how convenient it can be. For us, it's enough to bring this match-up to a tie.
