"It's all about the lenses"4.0 starson by klausmobile
Pros: * Access to Zuiko lenses.Olympus builds consistently good lenses at affordable prices. Equivalents for APS format are expensive and equivalents for full-frame are prohibitively expensive.
* Decent JPEG conversion engine for those hooked on JPEGs.
Cons: * 4/3 sensor will always lag behind competition in low-light noise department.
* "Olympus colours" look great but ruin natural skin tones.
* Too small for dudes with large hands.
Summary: A digital camera is, in essense, two things: a lens and a sensor. Think of both; it's a tradeoff.
Whether you're going to use the kit lens or replace it with something better, Olympus wins in the lens department over any competition. Olympus camera body is a ticket to the affordable line of excellent Zuiko lenses for the 4/3 mount. Sure, both Canon and Nikon sell equivalent quality glass for their APS platforms, but they are pricey. Prohibitively pricey when it comes to full-frame platforms (or non-existent at all).
There is, however, a caveat: E-620 is a very small camera. Mating it to a heavy lens, even the Zuiko 12-60 zoom, makes an uncomfortable, unbalanced front-heavy system. Always try before you buy it, with the right lenses, I cannot emphasize it more.The "button complexity" mentioned in CNET review is not an issue at all if the size is right for your hands AND if you can live with the narrow, dim, tunnel-like viewfinder.
Olympus sensor, on the other hand, loses to competition (that said, E-620 sensor is superior to earlier 4/3 sensors as on E-410 and E-3, which is yours truly's workhorse). Everything that has been said about superiority of APS-sized sensor over Oly's smaller 4/3 sensor is true. Yes, they lose in pixel-level resolution and in low-light shooting (noise at higher ISO). But in daytime (low ISO) conditions the difference is insignificant.
Another caveat must be said of the famed "Olympus Colours". Olympus produces consistently good landscapes and architecture shots, but the same JPEG engine that excels in landscapes causes unnatural skin tones (even under the finest natural lighting). Switching to RAW processing causes more confusion: few RAW converters are good in resolving proper skin tones from Olympus. Yours truly, for instance, uses Lightroom for most pictures but Silkypix for portraits.
