Zoom
The zoom control can be used to frame subjects
in the monitor or viewfinder. Select W to zoom
out, increasing the area visible in the frame.
Select T to zoom in up to 3.5× so that the subject
fills a larger area of the frame. The amount of
zoom is displayed in the monitor.
Holding the control to T at 3.5× zoom will trigger digital zoom, allowing the
subject to be magnified up to 4× more, for a total magnification of 14×.
A Digital Zoom
If possible, digital zoom will create a picture by cropping the area visible in the moni-
tor to the current image size (B 66), increasing magnification without affecting qual-
ity. If the crop would be smaller than the current image size, additional pixels are
added through a process known as interpolation, creating a slightly “grainy” image.
The amount of zoom available before interpolation is used depends on the option
currently selected for image size, as shown in the following table.
2 is displayed when interpolation is in effect. Using digital zoom at sizes of 3,648×
2,736 (j), 3,648×2,432 (h), or 3,584×2,016 (9) always triggers interpolation.
