Description : Coimbatore is the second Largest Industrial City in Tamilnadu, India. After the introduction of Cell Phones and Development of Mobile Technology, every one used to have a Phone or Mobile. To help to communicate among themselves, this CELFON5G Directory Services are introduced. Every Firm or Person owning a Mobile Phone or Fixed Phone is listed in this CELFON Directories. The Listing gives all 5 communication addresses like 1. Fixed Phone Number 2. Mobile Phone Number 3. FAX 4. Email Address 5. Web Site etc in addition to Postal Address. CELFON Directories are available is 5 Generations (5G) of Media, namely 1.Print Edition 2. Digital Edition for viewing in Mobile Phones 3. Searchable Mobile Apps 4. Web 5. CD etc. Considering the Lakhs of Users in Coimbatore, a single volume of Directory is difficult to handle. So the users are published in 10 Volumes, namely on * SIDCO * Town Hall * Gandhipuram * R S Puram * Thudialur * Ganapathy * Saibaba Colony * Singanallur * Peelamedu * Vadavalli etc. All these Volumes are Printed and Published as per a Time Plan, at regular intervels around the year. Digital Editions are available for each Print Edition. This Digital Edition is containing all volumes as and when published The first among the Series is on COIMBATORE SIDCO Industrial Area. Then followed by COIMBATORE TOWN HALL and COIMBATORE GANDHIPURAM. This Volume contain all the above, as on January 2018. At the time of creation, this Digital Edition is a replica of Print Edition. Later on Contents of this Digital Edition are updated every month with new users. This COIMBATORE CELFON Directory is a single Volume, containing all the Directories Published individualy for above areas. Seperate volumes are also available in Play Books. Updated every Wednesday of the week, containing informations received upto the previous early saturday. Recently updated on 4-4-2018

Description : From the front it resembles an oversized Nikon FM, the mechanically operated, interchangeable lens, 35mm SLR that was produced between 1977 and 1982. In addition to the styling and external controls, the Df's other reference to Nikon's history is the retractable meter coupling tab, which allows the use of pre-1977 non-AI lenses. Much of what lies is beneath the Df's decidedly retro skin, however, will be quite familiar to current users of modern digital SLRs. While the "e;D"e; in the name stands for "e;digital"e;, the "e;f"e; stands for "e;fusion"e;, referring to the marriage of old and new. Despite its pretensions of being a fully manual camera, the Df also features front and rear electronic control dials in addition to the physical dials on the top-plate. The Df is built around the 16MP full frame sensor from the company's flagship D4, and uses the processor and AF system from the cheaper D610 model. The optical viewfinder is very large; the magnification is 0.70x and the coverage 100%. When a DX lens is attached to the Df, the viewfinder shows frame-lines indicating the DX image area.Most notably, and unusual for a modern DSLR, although the camera is based on a video-capable sensor, the Df cannot shoot video. This, according to the developers, is because the Nikon Df is intended to be a serious camera for people who want to produce "e;pure"e; photography.UK author Jon Sparks provides practical tips on how to get the best from this versatile camera, in this comprehensive step-by-step guide that includes a pullout quick reference card.
