Anti Motion Blur. Similar to Hand-held Twilight, this mode is also designed for use indoors or in low lighting, but it’s more effective at reducing blurring that might be caused by a subject’s motion or by a shaky camera. That’s because the camera sets an even higher ISO level to be able to use an even faster shutter speed so you should not need to

But your polarizer, infrared, and neutral-density filters can all be shared among your lenses through the use of inexpensive step-up and step-down rings. The former allow using larger filters on lenses that have smaller diameter filter threads

with a color; as discussed below, that can be red, white, or yellow. The colored area shows you at a glance what will be very sharp if you take the photo at that moment.

A green dot surrounded by two brackets (curved lines) appears to indicate that the camera is not having a problem achieving and maintaining focus. The brackets disappear when focus is achieved, leaving only the green dot. If the camera should fail to acquire focus, the green dot disappears and the brackets remain. Continuous AF is a useful mode for

Superior Auto. If you opt for Superior Auto instead, this mode provides an extra benefit. In scenes that include extremely bright areas as well as shadow areas, the camera can activate its Auto HDR (high dynamic range) feature to provide more shadow detail. I’ll discuss this feature in Chapter 6. In very dark locations, it can activate the Anti Mot

Sony also recommends turning the e-curtain Off when you are using a lens made by another manufacturer, as exposure may be uneven or incorrect.

ISO Auto also allows you to choose a minimum and maximum ISO speed to be used. If you want to avoid noise, you could set the Minimum ISO to 100 and the Maximum to 800, and still gain the benefits of using ISO Auto. If you wouldn’t mind seeing a little noise, you could set the Maximum somewhat higher.

(The photographic “gray cards” you buy at a camera store have an 18-percent gray tone; your camera is calibrated to interpret a somewhat darker 12-percent gray.

The problems pop up because the e-curtain is, in effect, too fast. It reduces the shutter lag to the point that the iris may not have sufficient time to close completely before the exposure begins. So, the f/stop used at the beginning of the exposure can be different from the one used for the rest of the exposure (after the iris closes down to the
