To quote technologically, camera is the save button for the mind’s eye. A camera is an optical device which captures a photo of an image and stores it directly into it or allows a facility to be transferred to other devices. The term camera is derived from a Latin word ‘cameraobscura’ which means the dark room which projects images. There are different companies offering different types of cameras for the customers. There are three domineering companies in the business are Canon, Nikon, Fujifilm. Canon is a company of Japanese origin; they have a wide range of cameras varying from Polaroid, digital and DSLR. Canons rule the digital camera market with Nikon following it up. Digital cameras are a trend because you can view the image immediately after clicking and based on the choice they can be deleted and a new one can be taken without wasting the film role as in old Polaroid. There are two different types of digital cameras of which one being normal digital cameras and other is digital single lens reflex camera. The ruling DSLR cameras from Canon are the Canon EOS 7D Mark II Digital SLR Camera.
Canon EOS 7D Mark II Digital SLR Camera is a type of DSLR cameras which stands for electro optical systems. It was introduced in 1987 with an autofocus single lens reflex camera. The term EOS was inspired from the Titan goddess of dawn in Greek mythology. Canon has a tie up with Kodak which manufactures the EOS body. It uses the reflex technology which is the primary difference between DSLRs and other digital cameras. In this reflex models initially light travels through a lens to a mirror and deviates to send images using an image sensor present or the view finder.
Design and Working of DSLR
A mobile mirror is deviated to exactly an angle of 45° to focus the light from lens to a focusing screen through a condenser lens and a penta mirror to an image sensor. Focusing is given an option of choosing either automatic or manual depending upon the situation and photographer’s choice. The automatic focus makes use of phase detection mechanism instead of found maximization. This type of auto focus is very fast and accurate more than the old primary techniques. There a huge selection of lens with different focal lengths which can be alternated depending upon the need. Usually all DSLR cameras comes with an available focal length of 80mm. other specific focal lengths can be purchased at extra cost.
The advantage of using the Canon EOS 7D Mark II Digital SLR Camera is that they have an accurate precision of eye by tracking the eyeball movements. They are fitted with eye controlled focusing which autofocus a desired object in a scene based on where the photographer focuses in the view finder. They have a quick controlled dial which provides a touch screen facility to device parameters at the back of the camera. In addition to this, they have a multi point autofocus which makes this the bench mark for all other DSLR cameras. Read more…
