Noise

The A37's noise profile for JPEGs looks as you'd expect for a camera in this class: ISO 100 and 200 look good, you start to see artifacts at ISO 400, and the images are usable, depending upon content, up through ISO 3200.

JPEG, ISO 100

Not a stellar shot, but it accurately represents the general quality of the A37's low ISO sensitivity photos.

ISO 800, JPEG

You can see the noise and JPEG processing artifacts here, but they're not too obtrusive.

ISO 1600, JPEG

You can see the noise mottling in the sky and the detail degradation on the clock, but this would be quite usable scaled down a little. Also, a lot of shots of the clock face taken with other cameras/lenses display serious fringing on the high-contrast edges; here it's not a problem. I'm not sure if it's doing correction in-camera, though.

Color

The white balance here is a little cool because of the overcast weather, but the A37 generally produces accurate and pleasing color in its default Creative Style.

Bokeh, 18-135mm lens

Not beautiful, but the out-of-focus highlights of the 18-135mm look typical for a consumer lens.
