Focus Lock Shooting

Usually, the auto focus function focuses the camera on the subject that appears in the autofocus field on the LCD monitor or in the viewfinder. If the subject is located outside the autofocus field, it may appear blurred in the resultant shot. Use the focus lock to ensure accurate focusing on the subject.

See • “Checking the Position of the Subject” (p.45).

■When to Use the Focus Lock

If the subject is not positioned inside the autofocus field, a blurred image will result as the background, not the subject, is in focus.

If an object other than the subject occupies a major portion of the autofocus field, the camera will focus on the object, producing a blurred image of the people.

The Ricoh RDC-7, launched in the late 1990s, represents a significant step in the evolution of digital cameras, showcasing a blend of innovative features and user-friendly design. As part of Ricoh's line of digital cameras, the RDC-7 was well-regarded for its compact design and advanced capabilities for its time, appealing to both amateur and professional photographers.

One of the standout features of the Ricoh RDC-7 is its impressive 3.34-megapixel CCD sensor, which allowed for high-quality image capture. This resolution was significant for the era, enabling photographers to capture detailed images suitable for printing and sharing. The camera's focal length of 7.6 mm to 22.8 mm (equivalent to 38 mm to 114 mm in 35mm terms) provided flexibility for various shooting scenarios, whether it was wide-angle landscapes or closer portrait shots. Additionally, the RDC-7 incorporated a 3x optical zoom lens, enhancing its versatility and making it suitable for a wide range of photographic applications.

The design of the Ricoh RDC-7 featured an ergonomic grip and a user-friendly interface, which included a 2.5-inch LCD screen that permitted users to compose and review their shots easily.

The camera also included a robust menu system that enabled users to access and modify various shooting parameters, catering to both novice users and experienced photographers.

In terms of technology, the Ricoh RDC-7 utilized CompactFlash cards for storage, which was a widely adopted format at the time. This allowed for substantial storage capacity and quick data transfer. The camera also offered several shooting modes, including automatic, manual, and various scene-specific presets, giving users the ability to tailor their shooting experience based on environmental conditions.

Another key characteristic of the RDC-7 was its ability to record video clips in addition to still images. This added a multimedia capability that was becoming increasingly popular among digital cameras of that era. While the video recording functionality did not offer the high-definition standards of contemporary devices, it represented a forward-thinking approach to digital photography and content creation.

In summary, the Ricoh RDC-7 combined essential features, advanced technologies, and thoughtful design that made it a notable camera in the evolution of digital photography.
