CAMERA SENSITIVITY – ISO

Five settings can be selected for camera sensitivity: Auto, 100, 200, 400, and 800; the numerical values are based on an ISO equivalent. ISO is the standard used to indicate film sensitivity: the higher the number, the more sensitive the film. See setting the function dial section on page 48 to change the ISO setting.

The auto setting automatically adjusts the camera sensitivity to the light condi- tions between ISO 100 and 200. When any other setting than auto is used,

“ISO” will appear on the data panel, and “ISO” and the set value will be displayed on the monitors.

Photographers can select a specific sensitivity setting. Like grain in silver-halide film that increases with speed, noise increases with sensitivity in digital imaging; an ISO setting of 100 will have the least noise and 800 will have the most noise. A change in ISO also affects the flash range; the higher the ISO, the greater the range.

As the ISO value doubles, the camera sensitivity doubles; changing the ISO between 100 and 200, 200 and 400, or 400 and 800 changes the camera sensitivity by one stop or 1 Ev (p. 79). A change between 100 and 800 changes the camera sensitivity by a factor of 8 or three stops. High ISO set- tings (400, 800) will allow the photographer to hand hold the camera in low-light conditions without the need of a flash.

Camera Notes

When making bulb exposures (p. 57), noise can be more pronounced because of the unusually long exposure times, especially at 400 and 800 ISO. Longer bulb exposures at lower ISO set- tings will be less affected by noise than the equivalent exposure at a high ISO. For example, a fifteen second exposure at ISO 200 will have less noise than a four second exposure at ISO 800. With long exposures at high ISO settings, noise from interference may be noticeable.

7Hi specifications

The Konica Minolta 7Hi is a notable entry in the world of digital cameras, targeting both enthusiasts and professionals seeking high-quality imaging and advanced features. Released as a part of the DiMAGE series, the 7Hi gained acclaim for its enhanced performance, crisp image quality, and versatile capabilities.

At the heart of the 7Hi lies a 7-megapixel CCD sensor, which delivers exceptional detail and vibrant colors. This resolution positions it well for high-quality prints and cropping options, appealing to users who value image fidelity. The camera supports a wide ISO range from 100 to 800, enabling it to perform effectively in various lighting conditions. The advanced image processing engine helps to achieve low noise levels, ensuring clear images even at higher ISO settings.

One of the standout features of the Konica Minolta 7Hi is its 28-200mm equivalent zoom lens. This high-quality lens provides a flexible focal range, allowing photographers to capture wide landscapes and intimate portraits without needing to switch lenses. The lens also includes advanced glass elements that reduce chromatic aberrations and improve sharpness, enhancing the overall image quality.

The camera’s build quality is robust, with a comfortable grip and a user-friendly interface. The large, high-resolution LCD screen allows for easy composition and menu navigation, while the electronic viewfinder provides an accurate representation of the final image. Additionally, the 7Hi offers a variety of shooting modes, including manual, aperture-priority, and shutter-priority, giving users the creative control they desire.

Another notable aspect of the 7Hi is its image stabilization technology, which significantly minimizes blur caused by camera shake. This feature is particularly beneficial for handheld shooting at slower shutter speeds, making it easier to capture sharp images in challenging conditions.

The Konica Minolta 7Hi also supports various image formats, including RAW, which is essential for photographers who require maximum flexibility in post-processing. The camera’s ability to shoot in both JPEG and RAW formats provides users with the option to choose the best fit for their workflow.

With its combination of advanced features, exceptional image quality, and user-friendly design, the Konica Minolta 7Hi stands out as a compelling choice for digital photography enthusiasts looking for a reliable and versatile camera. Its marriage of traditional photographic principles with modern digital technology ensures that it meets the demands of both casual shooters and serious professionals alike.
