Whether in the digital camera into the consumer market at the beginning or today, there are many players still have such confusion and doubt: "Digital camera is very easy to miss the best shot opportunity", in fact, this issue has been there, this is usually due to "delay" caused by, and this is one major drawback of digital cameras, "delay" refers to pressing the shutter to the actual shooting time. Compared with traditional cameras, most consumer digital cameras than the longer delay. Hard to find opportunities to press the shutter after the shooting to the effect was the next moment. Time is life for the shooting of photography, this problem is especially serious.

Figure 1 Figure 3 is a pointer around in the metronome during exercise, in that position the pointer right through the middle of shooting to press the shutter. Since making a big error, and therefore shot three times, and are synthesized together, the picture looks blurred because the synthesis of reason.

Were used in digital cameras Casio "QV-R4", Nikon "COOLPIX4500" and Casio "QV-4000" three models. Although this is just one example, but a clear style to tell people a short delay before shooting time to capture.

The most common delay is the "release time." AF digital camera shutter according to the first half of the position to be able to focus. Release time aligned generally refers to the case in focus from the moment the shutter to the time between pictures.

Another somewhat lax to say is "shutter lag." Shutter lag is not half-press the shutter, but when you press the shutter once to be able to capture the time, that means in most cases, including auto focus play a role in the release time lag of time. This time, shutter lag including autofocus time.

In fact, when shooting, it should be noted that from the open source to the actual shooting time, and press the shutter from pressing the shutter to the next available time. In addition to the shutter delay shutter outside the interval, plus a memory card to transfer data to the time.
By saving the data transmission time to say to capture the photo opportunity, and that is burst mode. Burst mode data into a digital camera by the internal high-speed memory (cache), rather than transferring data to the memory card can be taken in rapid succession, multiple photos.

Although generally a longer delay of digital cameras, but how to shoot the camera to capture time, the manufacturers have started to take countermeasures.

At present, many new digital cameras from top to bottom in the delay of the effort to solve the problem, Casio's "QV-R4" release time of 0.01 seconds, faster than the high-level SLR cameras. Ricoh is also the latest G4 shutter lag of 0.1 seconds, Sony's "DSC-F77" selling point is the start time of 0.9 seconds. Panasonic "LUMIX · DMC-FZ1" shutter delay is only 0.1 seconds, Fuji launched the new "FinePix F410" cycle with a very innovative multi-shot, according to the shutter in a row, it will record 0.3 second intervals images, the moment the shutter open as to retain the last four photos. Sanyo's "DSC-MZ3" The shooting also used in a similar way, the shortest interval of 0.06 second can record the image the instant you press the shutter.

From the shooting point of view, delay is inevitable, but if you are looking for a solution of non-secret, then do not look at the LCD screen when shooting can be said that the key to success. Because the LCD screen itself, there appears to lag. Through the viewfinder, or used a tripod fixed camera, while pressing the shutter while observing the scene, over and over to take the time to capture.


0.01 second shutter release time of the Casio "QV-R4". To capture the moment in the can press the shutter.


If the forecast does not move quickly pressed the shutter, you will miss the shooting time.


Casio's "QV-400" photographed and COOLPIX4500 similar results.


By Casio "QV-R4" photo shoot. In order to have shot the ball into the characters and the need to see the display, so there will be delay in the timing of pressing the shutter. However, "QV-R4" The delay is only 0.01 seconds, so it is a smooth shooting.




This is also the use of "QV-R4" photographed the results. As the light brightness is insufficient, so shooting forced the shutter speed increases.
