Many people want to buy SLR may not know why it is called that name. SLR stands for “single lens reflex camera”, Hong Kong and Taiwan are accustomed to using simple and the “SLR” to refer to; English and translated into “Single Lens Reflex Camera”, referred to as “SLR. Phrase in the” reflective “refers to The reflector inside the SONY NP-BN1 battery camera components, precisely because of such re-framing camera lens directly reflects the light with reflectors, and ultimately through the viewfinder is the photographer saw the naked eye, so no aberration SLR has the advantages of shooting, while shooting must also open the lens cover before shooting can be. But the moment you press the shutter, to allow rear access to film or light sensor, located within the reflector body must have a process of rising and then falling, resulting in weak shutter stagnation, and will block the sight of the viewfinder and have a greater voice, and the resulting moment of shooting shooting blind and larger noise at work.
SLR reflector optical structure is undoubtedly one of the keys (the other important component is the pentaprism or penta-mirror), it is also the achievements of the advantages of NIKON EN-EL14 Battery SLR decided disadvantage. In addition to the shutter lag, instant blind spots and work noise, and indispensable to install the reflector tilt, and at the top of the fuselage or five mirror pentaprism SLR camera body also allows the volume in general more cumbersome; to the electronic and digital era, built-in flash, image sensor and LCD screen and other new parts added, making the SLR body thickness increased. Coupled with the length of the lens aperture and a corresponding large, so the pursuit of light users, not how they structure SLR Heart; but in others it seems some friends, may not be huge in size disadvantage, but not the conveniently small.
To illustrate the advantages of SLR, will inevitably have to mention the SLR system in many ways, “opposite” side-shaft structure. This is precisely the two civilian 135 design schools of the two SONY NP-FW50 battery cameras, the fundamental difference is that framing differences. Frame SLR, the lens, reflector, pentaprism (penta-mirror) and the center of the viewfinder are in the same axis, so is the coaxial viewfinder. The ordinary rangefinder camera viewfinder and the lens does not have direct optical association (no need to open the lens cover can also be shooting) and not on the same axis and therefore have a “next to the axis” of the name. “SLR” and “next to the axis”, has a great deal of diversity in the technical advantages, resulting in some of the finished machine on the strength of clear performance indicators.
Structure, next to the axis of the camera with a compact SLR camera compared to work less vibration and noise, etc., in theory, within a specific focal lengths can also have better imaging capability. At the same time, the inspiron 6400 adapter SLR viewfinder frame greater than visual range – most of the viewfinder rangefinder format can be seen shooting outside a small part of the screen, but often only see the SLR viewfinder and even less than the film within the film format format images, compared to the natural Rangefinder cameras allow the photographer more is expected of the opportunity to grasp the moment of capture. The downside is that, next to the axis of the lens frame as the viewfinder and not in the same axis, the same height, so the viewfinder field of vision there is a certain vision and the actual shooting aberration, not as direct as the SLR system to achieve “WYSIWYG” (but part of the high-end rangefinder camera with automatic parallax correction function). Clearly, in the framing, the two have their own advantages. Fast forward in technology today, the birth and development of NIKON EN-EL14 battery electronic viewfinder, gave birth to a fundamental change has already begun – in the field of civilian products, next to the axis optical viewfinder is declining, while the SLR optical viewfinder still relatively strong vitality.
Recalling the film era, came later, shape and work noise were more SLR, but instead in the market competition to win more and more attention of high-end users – both professional journalists or photographers, SLR cameras was that they indispensable choice. Traced the structure in the macro and telephoto lens reflex viewfinder rangefinder camera has a capacity can not match the inherent advantages, making it easier to obtain comprehensive Safe focal lengths and distance shooting range, and thus make many subjects become more abundant. But next to the axis of the camera and not because of the growing popularity of SLR die out, but in the short perspective on its own terms and standards of imaging quality advantages of perspective and their own structural characteristics of light and softly, making photography documentary photography and the human weapon. In fact, the film was a smash hit-style shoot rangefinder-style is an important part of the dell inspiron 6000 adapter product; therefore in terms of market share, next to the axis of the camera at the time may have a larger user base.
