Digital Single Lens Reflex vs. Digital Single Lens Translucent


This is a review of today’s new technology of photography. In this picture (right) you can see a camera with Carl Zeiss optics. This kind of camera is not just like a conventional camera that is commonly used in capturing special moments, here’s the review of DIGITAL SINGLE LENS REFLEX (DSLR) comparing with Sony’s DIGITAL SINGLE LENS TRANSLUCENT (DSLT). In our everyday lives, amateur and professional cameras are being used to capture special moments like Christmas Day, New Year’s Day or just an ordinary occasion. Digital compact cameras are great for taking fun snaps with friends and showing them off to anyone who is interested. If the image does not come out well, simply delete it and take it again. If you are happy with the results in the LCD, you have your image. Some features of digital compact cameras are not sufficient to get the right focus or your desired focus due to its focusing ability. For example, you wanted a close up shot or a macro shot of a ring with a diamond on top. Probably, the photographer will set his camera on macro mode and the camera automatically sent a signal going to its processor, outro the processor, the lens drive motor will performed to get the acceptable focus to the subject of photography. Sometimes compact cameras fails to adequately give the right focus for the subject of photography- some part of the subject losses its focus and the other part is extremely focus. As the result of image, the viewer of image fails to reach his satisfaction.

Engineers of camera set a research to point end the problems in getting the right focus, contrast, brightness and colour. DSLR was born! What is a DSLR? The acronym DSLR stands for ‘Digital single lens reflect”. When you use a DSLR, the picture is composed and taken through the camera’s single lens. ‘Reflex’ refers to the mirror which is used to reflect the image up into the viewfinder until the moment the shutter is released. The mirror flips up at the back of the image then passes to the sensor at the back of the camera. Hence, the image is processed correctly. If you noticed, DLSRs are more bulky compared with a compact camera because DSLRs have a bigger lens and it have bigger sensors which give better picture quality more advanced photographic controls. Despite their size, most DSLRs are not too heavy, thanks to the use of poly-carbonate. What is poly-carbonate? A DSLR is made of poly-carbonate housing that has a lighter body weight compare with a camera made of plastic housing which gains more weight and can be cause of uncomfortable feeling for extended time of use. Plastic housing have less pressure strength, if you accidentally drop your DSLR to the floor and it might break the external parts of your camera and can be cause of miss alignment on  its movable mechanism like, rotating dial, lens drive motor or even went to permanent disability of your camera. Poly-carbonate is composed of two materials which give more pressure strength that couldn’t affect the weight. Now these days poly-carbonate are commonly used in many types of electronics gadgets.


Let’s talk about the lens ability of DSLRs. Not like a compact camera it has a fix lens assembly. DSLRs cameras enable you to change lenses to achieve a variety of effects. The camera’s standard lens will give an angle of view roughly similar to that perceive with the naked eye, a wide-angle lens enables you to get more into the frames, while a telephoto magnifies distant objects. Lens properties of DSLRs, there are other properties to take into account, apart from their focal length, including the maximum aperture. The larger the maximum aperture, the more light the lens can gather. This is useful in poor light or whenever you want shallow depth-of field in your photographs. Zoom lenses, in modern cameras, zoom lenses have largely taken over lenses with fixed focal lengths (‘prime’ lenses). The versatility of zoom means that you do not have to carry around a number of different prime lenses, or keep changing lenses for different subjects. However, zoom lenses do have a couple of intrinsic disadvantages. One is that their maximum apertures are lower than those of prime lenses. Whereas a 50mm prime lens might have a maximum aperture of f/1.8, a ‘typical standard zoom’ might have a maximum aperture of f/4 at this focal length.


As the innovation of cameras continuous, Sony launched their first camera using a translucent mirror. The SONY α 99 SLT-A99. This camera of Sony slams DSLR from their techonolgy in picture innovation, as we reviewed earlier about DSLR these four letters abriviates the word Digital Single Lens Reflex which used a transparent mirror to get a correct focus of still image. But the other problem is, if you want to get the focus of the moving image, the problems is the camera that is currently in used is struggling to get a the desired focus, with a sleeker form factor than regular DSLRs, TMT is blazingly fast. It’s easy to take any shot that is hard to capture with conventional DSLR perfect focus. Unlike regular DSLRs, the αSLT camera offers fast, accurate and continuos focus on moving subjects to easy create professional-looking movies. The benefits of Sony’s Translucent Mirror, this allows tracking of subjects on the move without delay and greater clarity. With it’s 24.3 megapixel resolution you never get lost with any detail of your subject also with it’s 35mm full-frame Exmor™ CMOS Imaging Processor gives more accurate balanced. Sony has their advanced Integrated BIONZ™ Image Processing Engine tha allows to process and correct the subject taken by a photoghrapher. If you want to get a frame shot in a second Sony α is equipped with 10 frames shoot. In a place with a poor light enviroment cameras is struggled to capture more light, with Sony DSLT, poor light place is not a problem anymore with the ISO of ISO 100 to 25600 (expandable to 102,400) your picure is still rich in details. This part tackles the housing of this camera, this DSLT camera is made of Robust Magnesium Allow Body more lighter than poly-carbonate and applies more pressure strenght for protection of your camera’s internal components. This brand won multiple awards for its excelent contribution on picture innovation. On 2011 on the TIPA awards Sony won the, “Best Imaging Innovation” followed with the TIME MAGAZINE AWARD, Sony was awarded in 50 Best Inventions Year Award- “A.K.A. the camera that never blinks..” with an ingenious translucent mirors that stays put. That means you can shoot up to 10 perfectly focused photos a second and record HD video that never goes blurry.
