Olympus E-620 Digital Camera Review$699.99
Turning off noise reduction entirely to maximize image sharpness produced easily visible image noise by the time we reached ISO 400, and the problem accelerates rapidly from that point. The low noise reduction setting offers a major improvement at high ISO levels, but not enough to solve the problem. And while the two highest settings maintain sub-2% image noise across the board, the loss of image sharpness is readily apparent.
The E-620 noise curves are all tightly clustered for red, green, blue, yellow and luma (gray) noise, with no single component color spiking (which can be highly visible). More on how we test noise.
Available ISO values range from 100 to 3200. The ISO step value can be changed from the default 1 EV to 1/3 EV if you prefer finer increments.
In Auto ISO mode, both the default value to be used and the maximum allowable ISO can be set, from 200 to 3200 in 1/3 EV increments. ISO bracketing, a relatively unusual feature, is also available, providing a three-shot sequence with 0.3, 0.7 or 1 EV increments.
