Manual Control Options
There are quite a few manual control options if one can find them. The aperture and shutter speed can be changed via the Set button and the LCD display information. The manual focus can be changed with the four-way dial and the sliding bar. In the EX button’s menus, the ISO, white balance, exposure compensation and metering can be manually adjusted.
Auto Focus
The Casio Exilim Z750 has a contrast auto focus system that offers the following options: spot, multi, free, macro, infinite, and focus lock. These can be changed by pressing the EX button and selecting the desired auto focus option. The normal auto focus system on the Z750 can focus as close as 40 cm. In macro mode, the lens can focus from 10-50 cm. The auto focus works fairly quickly and is activated when the shutter release button is pressed halfway. When the Continuous Zoom function is enabled, users don’t need to press halfway; the zoom constantly focuses. This option is virtually silent, which is rare for compact digital cameras. This is a broad range of focal options for an automatic point-and-shoot and provides significant flexibility for its styling and price.
Manual Focus
Manual focus is available on the Exilim Z750. Like most compact digital cameras, the manual focus is operated with a sliding bar on the LCD screen rather than a focus ring. While the sliding bar-method of focusing isn’t the truest form of manual focus, it is helpful to have when there is a small subject that is difficult to automatically pinpoint.
Exposure
The following exposure modes are available on the main mode dial: Snapshot (automatic), Best Shot, Movie, Voice Recorder, Manual, Movie Best Shot, Short Movie, and Past Movie. Exposure compensation is available with still pictures from +/- 2 EV in 1/3 steps.
White Balance
The white balance options can be found in several places, including the EX menu and the Quality menu. Users can scroll though icons and text and select one of the following options: Auto, Daylight, Cloudy, Shade, Fluorescent 1, Fluorescent 2, Tungsten, and Manual. Again, this is a healthy range of options for a point-and-shoot and should provide significant opportunity for color precision.
ISO
The Casio Exilim EX-Z750 automatically sets the ISO from 50-400 unless the user manually adjusts it. The following ISO selections are available: 50, 100, 200, and 400. This is a standard range for a compact digital camera but the ISO 50 setting is certainly welcomed beyond an ISO80 or 100 bottom end of the range.
Shutter Speed
The Casio Exilim EX-Z750 has a CCD electronic shutter and mechanical shutter with a speed range from 1/8-1/2000th of a second in the normal shooting mode. In the Night scene mode, the speed slows up to 60 seconds and in Fireworks mode, it slows to a fixed 2 second duration. The shutter speed appears on the information that overlays the image being viewed on the LCD screen. It can be changed by pressing the Set button.
The 3x optical zoom lens has apertures ranging from f/2.8-f/5.1. This information also appears on the LCD screen with the shutter speeds to help monitor exposure.
