One inch sensor

Generally, the one-inch sensor is commonly utilised in bridge cameras, comparable in size to entry-level DSLR/Mirrorless cameras. These cameras possess a fixed telephoto lens and are compact, resembling traditional point-and-shoot cameras. The advantage of employing this sensor lies in its relatively large size when compared to the sensors found in most mobile phones available in the market. Consequently, it has the potential to capture more light, resulting in significantly improved image quality, particularly for those proficient in utilising its comprehensive range of features and manual settings. These cameras are typically feature-packed and user-friendly, offering convenient auto and semi-auto shooting modes. However, they usually come at a higher price than average entry-level mirrorless cameras bundled with a basic kit lens.

The one-inch sensor is well-suited for individuals seeking to capture higher-quality images than what can be achieved with most mobile phones. It offers the choice of a discreet, pocket-sized version or a bridge camera, which provides a versatile zoom range without the need for lens changes. It is important to note that the one-inch sensor has a crop factor ranging from 2.7 to 3. Unless explicitly stated by the manufacturer as "35mm or Full Frame equivalent," as is the case with many Sony cameras, it is necessary to multiply the focal range by 2.7 to 3. For instance, an 8mm focal length would become 21.6mm or 24mm.

Sony RX100 - The initial release from Sony, known as the "Pocket Rocket," features a 20-megapixel sensor with a fast aperture available across the 24-70mm zoom range (equivalent to 35mm). It offers satisfactory focus speed, incorporates face detection technology, and supports 1080p video recording. One drawback, however, is the absence of a viewfinder, which can make outdoor usage challenging under bright sunlight. While the 20-megapixel sensor may not be as technologically advanced as subsequent RX models, it still surpasses the image quality produced by the majority of mobile phones.

Sony RX10 II – This outstanding bridge camera is a versatile option that excels in various areas. The term "bridge" in its name refers to its ability to bridge the gap between traditional DSLR and compact cameras. With a 20-megapixel sensor, it offers an impressive zoom range of 24-200mm (equivalent to 35mm) and maintains a bright aperture throughout the entire zoom range. It incorporates features such as face detection, slow-motion capabilities up to 960fps, decent focus speed, and the ability to record videos in 4K resolution. Additionally, it includes an external microphone input for enhanced audio quality and a built-in ND filter, enabling users to achieve smooth waterfall or still water effects through long exposure photography. Moreover, this camera is weather-sealed, providing resistance against dust, sand, and rain, ensuring its durability in challenging conditions.

Nikon J5 – Presenting a compact and aesthetically appealing retro-style camera, Nikon's final CX mount offering (Nikon's term for the one-inch sensor system) seemed promising on paper. Boasting a new 20-megapixel sensor, fast hybrid focus utilizing both contrast and phase detection, face detection, subject tracking, rapid shooting capabilities of up to 60 frames per second, 4K video recording, as well as WiFi and NFC connectivity, it even supported an interchangeable lens system. Regrettably, its real-world performance fell short of expectations. On one hand, it faced stiff competition from Sony's RX100 III and IV, which featured the same sensor size but were smaller in overall body size and offered brighter aperture fixed zoom lenses. On the other hand, it found itself in direct competition with Sony's A5100, an interchangeable lens camera with a similar body size but a larger APS-C sensor, available at a comparable retail price. While this Nikon camera delivered outstanding still photos, its 4K video recording capability was limited to a mere 15 frames per second, rendering it essentially impractical. Consequently, it found itself in a predicament without a clear market position. Moreover, due to the lack of extensive lens options and its failure to gain popularity, Nikon ultimately decided to discontinue the system.

Sony RX100 V – At first glance, the RX100 V may seem comparable to its predecessors in the RX100 series. However, it sets itself apart with the addition of phase detection, significantly enhancing its autofocus speed and subject tracking capabilities. It retains the 24-70mm (35mm equivalent) fixed zoom lens, which maintains a bright aperture throughout the zoom range, as well as the ability to record 4K videos. The inclusion of a pop-up electronic viewfinder, akin to versions III and IV, proves beneficial when shooting outdoors under bright lighting conditions. Notably, in comparison to certain older models, the RX100 V lacks built-in ND filters.

Sony RX100 VII – Sony presents the ultimate pocketable zoom camera, featuring an updated 20-megapixel sensor and a versatile 24-200mm zoom range (equivalent to 35mm). While the aperture may not be as bright at the longer end (200mm), it still delivers commendable image quality that surpasses the capabilities of digital zoom on mobile devices in 2022. Notably, this camera incorporates an impressive eye and face tracking system, utilizing the same advanced algorithm found in Sony's professional camera range. With rapid focusing capabilities, 4K video recording, and slow-motion functionality of up to 960fps, it caters to a wide range of creative needs. The improved operation of the electronic viewfinder ensures a seamless user experience. However, it is worth mentioning that this model lacks built-in ND filters found in some of its older counterparts. Additionally, its premium quality and features come at a price, with a retail price comparable to mid-range mirrorless cameras at the time of its release.
