[Question] What is the Auto resize zoom?

This function allows you to crop and record a shot image. Conventional digital zoom enlarges a portion of an image to a set magnification. Whereas, auto resize zoom saves the cropped portion of the image, the image quality is not decreased by enlargement. The image recording size changes depending on the auto resize zoom magnification.

Auto resize zoom is available only when [Picture Quality/Size] is set to 4:3F, 4:3N (3648 × 2736) only.

Example: 4:3 (3648 x 2736) image (original)

Auto resize zoom

Auto resize zoom crops an image with , to 4:3F, 4:3F, 4:3F, or 4:3F (same magnification) without enlargement.

Cropped image examples :

As shown above, you can save the cropped image. Regardless of the magnification ratio, the image quality of the cropped image is as same as the original one. (However, when you increase the magnification ratio, the image size will become smaller.)

Zoom Magnification	Focal Length	Image Size
Approx. 1.0x	300mm	4:3F, 4:3N
Approx. 1.4x	420mm	4:3F
Approx. 1.8x	530mm	4:3F
Approx. 2.9x	850mm	4:3F
Approx. 5.7x	1710mm	4:3F

* Values of the focal length are equivalent to those on 35 mm film cameras.

Digital Zoom

The digital zoom enlarges a cropped image with interpolation. The higher digital zooming, the larger magnification with the smaller area. The image size (pixel dimensions) is the same as the original one, and it looks as if it were the extension of digital zoom, however, it is grainy and has a lot of noise.
