So far, we know the term or abbreviation SLR cameras from a single lens reflex. Why is “single” and why use “reflex”? The system comes complete SLR camera system lenses previously used double (double), the camera system of double-lens system (see picture).
Double-lens system for targeting dividing lens (lens up) and the lens through which to send pictures to the film (lens down). Single lens system complete with wearing only one lens, aka lens and lens to shoot pictures into a single shipper. So, to divide this work is necessary to mirror reflex lid quickly.
Mirror reflex SLR camera tilted at 45 degrees to send the image to the viewfinder with reflecting upward (see figure diagram). And, this mirror reflex movement will lift up when the shutter massaged so that the image sent to the recording field is located behind the mirror. Field can record movies on conventional cameras, digital sensors to digital cameras.
In this digital age, the reflex mirror images can be eliminated because the target can be generated by the sensor field at once. So, when the reflex mirror is removed, the camera with this system no longer be eligible to carry the nickname SLR because it did not have the reflex mechanism again.
Digital world is changing all the paradigms of photography. In the early ’90s when the digital era began, the digital camera is only used to replace film with digital sensors. The Company is the first Olympus SLR camera designed purely digital from the beginning in the early 2000s.
“Life view”
Since the early 2000′s, digital cameras are divided into three classes, namely DSLR (digital SLR), Prosumer (like SLR but the lenses can not dilepastukarkan), and a pocket camera. The fundamental difference between DSLR and her siblings are targeting the problem. Prosumer cameras and compact cameras can shoot through the LCD screen because the sensor can directly send the image to targeting. Things like this can not be done in the camera because the sensor DLSR just received a picture after lifting the reflex mirror.
In April 2006, Olympus issued E-330 camera can make life view alias can shoot from the LCD screen. This system was initially derided as a user of SLR cameras so “stupid”, as if a pocket camera for shooting from the LCD screen.
However, in use, the system life view was very profitable because photographers can shoot with more freedom, including the camera at a very low position, or very high. By looking into the LCD, the eyes of photographers no longer need to stick to the viewfinder should use ordinary SLR camera.
Slowly but surely, other DSLR cameras began to apply this view life system.
One of the most important thing is that later surfaced when he was able to view life, what good is a mirror reflex? What if the mirror was removed?
We remember in the days of film, set the lens diaphragm. Then, when the camera into the electronic era, bracelets diaphragm because the diaphragm shall be removed electronically from the camera body. By removing the bracelet diaphragm in the lens, lens prices so much cheaper then.
If the reflex mirror is removed, the price of the camera must also decline because of a complicated mechanism is removed.
Disappearance mirror reflex also brought other consequences. Flang distance or distance from the lens holder to the sensor surface can be reduced. Empty space left by the mirror reflex lens position can be replaced with a new system.
“Micro four thirds”
So, in August 2008, the two companies, which Olympus and Panasonic, announced a new camera system that they call them micro four thirds system (MFT). The system is updating their old system called the four thirds system (FT), by eliminating the reflex mirror, and then make a new lens system adapted to the loss of space due to the reflex mirror.
MFT system allows a lens system is much more concise. Note the diagram on this page. If the distance flang FT system is 38.67 mm, MFT system flang distance is 20 mm. It is conceivable that later MFT lenses much smaller than its predecessor.
See the comparison MFT 200 mm lens f / 4 with a 300 mm lens f / 4 system at 135 on the image of this page. Because of the small sensor size, MFT 200 mm lens is equivalent to 400 mm lens on a normal 135 system.
SLD
MFT system camera with lenses no longer reflexively, the SLR is not appropriate nickname for this species. Appropriate nickname for him is the SLD aka digital single lens.
SLD deserves the nickname because it is not possible to use other systems the same way, namely by removing the mirror reflexes. So, rather than just the FT system that will remove the lens. It’s not impossible Nikon, Canon, Sony, and Pentax also will create a new system without a reflex mirror.
Panasonic launches its SLD camera first, Lumix G1, in October 2008. Two months later Panasonic adds video functionality to the camera with a GH-1.
On June 16, 2009, turn to the official Olympus camera out of his SLD named EP-1.
Compass who tried both cameras felt great practicality in both. Lightweight and compact, but produces images with quality in accordance with his time. Both G-1 and EP-1 could be held in the palm of an adult’s hand (see picture). Lens system they are also lightweight and tiny.
Trouble shooting via the LCD is still complained of many professional photographers. Viewing digital images by viewing the real image is very much different and this may require conditioning, as well as those now used to meet in cyberspace through Facebook. Even so, Olympus provides a solution for this, namely by adding an optical viewer in EP-1 (optional), as shown in the picture in this page.
In the future, the camera seems to be shifting SLD total Prosumer camera. Olympus and Panasonic seemed to have stopped production of their Prosumer.
Want to know what “more terrible?” By adding an adapter, the camera SLD in the future could use the lens of any brand. Once again, anything!
