Canon EOS 70D

The Canon EOS 70D is a digital single-lens reflex camera from Canon. The EOS 70D was announced on 2 July 2013, to replace the EOS 60D, and was first available in late 2013. The camera is available bundled with either the EF-S 18–55mm IS STM, EF-S 18–135mm IS STM lens or as a body only.

The Canon EOS 70D is the launch platform for Canon's Dual Pixel CMOS Autofocus, which provides great improvement in focusing speed while in Live View, both for stills and video. At large apertures such as f/1.8, the 70D's Dual Pixel CMOS Autofocus provides a significant improvement in focus accuracy and consistency over conventional autofocus.

Online shopping

Online shopping (sometimes known as e-tail from "electronic retail" or e-shopping) is a form of electronic commerce which allows consumers to directly buy goods or services from a seller over the Internet using a web browser. Alternative names are: e-web-store, e-shop, e-store, Internet shop, web-shop, web-store, online store, online storefront and virtual store. Mobile commerce (or m-commerce) describes purchasing from an online retailer's mobile optimized online site or app.

An online shop evokes the physical analogy of buying products or services at a bricks-and-mortar retailer or shopping center; the process is called business-to-consumer (B2C) online shopping. In the case where a business buys from another business, the process is called business-to-business (B2B) online shopping. The largest of these online retailing corporations are Alibaba, Amazon.com, and eBay.

History

English entrepreneur Michael Aldrich invented online shopping in 1979. His system connected a modified domestic TV to a real-time transaction processing computer via a domestic telephone line. He believed that videotex, the modified domestic TV technology with a simple menu-driven human–computer interface, was a 'new, universally applicable, participative communication medium — the first since the invention of the telephone.' This enabled 'closed' corporate information systems to be opened to 'outside' correspondents not just for transaction processing but also for e-messaging and information retrieval and dissemination, later known as e-business. His definition of the new mass communications medium as 'participative' [interactive, many-to-many] was fundamentally different from the traditional definitions of mass communication and mass media and a precursor to the social networking on the Internet 25 years later.
