Some kownleage about Canon Digital Camera delay

What is a digital camera delay?
Delay time, digital camera, including focus, shutter delay and storage time, time is the focus CANON NB-9L battery camera with auto focus, auto focus time. Whether this time delay is a traditional film camera or a digital camera there, so the camera can not be regarded as unique.
Shutter delay is measured from pressing the shutter release button to start the period between exposure, in fact, is pressing the shutter to be able to actually take the time. Traditional cameras due to mechanical movement takes time, but also the shutter delay, usually about 0.05 seconds, said the traditional Canon Digital Camera Battery shutter lag can be ignored, to the digital camera has become a common problem here, is relatively traditional camera, digital camera not only has the time required for mechanical movement, more of the light signals into electrical signals (simulates signal), the electrical signal converted to the data. Although the photoelectric conversion time is very short, but the data processing speed camera used by the CANON LP-E10 battery CPU speed. If you use the LCD viewfinder, the delay will be greater, because the image through the lens, CCD and software processing is reflected in the LCD viewfinder screen then also take some time. Therefore, the impact of digital camera shutter lag is a major factor in delay.
Storage time is to take a picture, the Camcorder batteries memory card to transfer data to the time, which is a phenomenon unique to digital cameras. However, some high-end digital cameras currently used cache mode basically solved the problem, but the general consumer digital camera, or storage time delay of one aspect of a universal laptop ac adapter.
To avoid delay of Canon Digital Camera Battery, we need to clear the meaning of what is the delay, I refer to the digital camera delay is a broad concept, is present in the digital camera all the time during delays, including the focus time, the shutter delay and storage time.
Since the composition of a digital camera delay we have a basic understanding of the cause, then we can prescribe the right medicine, and specifically how to avoid delay of digital cameras we can according to their preferences and choose a different method of characteristics.
1.When choosing a digital camera as far as possible we should pay attention to select the shutter delay and storage time of the smaller camera. Of course, the CANON LP-E10 battery is the official publication of the delay data obtained in a particular test environment, but can be used as comparative data are available for reference.
2.Try not to use when shooting LCD viewfinder, because the Digital Camera Battery LCD screen display, is the result of the processed image data will normally take longer than the optical viewfinder time. Of course, this method used for screen viewing habits may be some people who are not accustomed to, but in capturing sports scenes, we occasionally change his habits.
3.For shot AF mode, we can advance to lock focus, or simply to cancel the auto-focus, thus reducing the time required for AF.
4.Delays are familiar with the camera on the motion state of the subject matter has been estimated that the length of delay of the Camcorder batteries, press the shutter to capture sufficiently in advance to take the time. This method is commonly used in the actual shooting, but need some experience, beginners can practice a lot.
5.Reduced under the conditions allowed the photo size, lower quality and higher compression ratio, which is to improve frame rate and reduce the delay a good approach shot, which is more suitable for Web browsing shooting low pixel dynamic photos.
Can also use the continuous shooting of CANON NB-9L battery digital-phase, taken in rapid succession, multiple photos, will be recorded continuously moving objects, and finally selected from the numerous photos of a photographed moments. However, the choice of continuous shooting mode, we have some time to pay the cost, because the camera will have to spend more time on the temporary storage of data in the cache memory card write for us again to press the shutter time is even longer wait, that is, the phenomenon of shooting delay it even more apparent.
6.To some extent, these methods can ease the "shutter lag" caused by regret.
When choosing a digital camera, we have positioned according to their needs, in addition to the shutter delay and storage time and other relevant parameters should pay attention, it should be noted that from the open source to the actual time required for filming, also known as the universal external laptop battery starting time 〔〕 other indicators. Most commercial grade specifications of the camera's manual or on the table, several indicators are not detailed in this publication is to avoid intentional or inadvertent mistakes, we do not comment. Anyway, in actual use, a serious impact on several indicators that the response speed of the camera, especially in the continuous capture of sports scenes, this effect was more significant.
Shot End
With the improvement of production technology of digital cameras and continue to lower production costs, more than 500 million pixel digital camera has been very popularity. High-end professional-grade canon digital camera was close to the operating function is a traditional camera, such as with a variety of exposure compensation, flash control and zoom control, has been basically able to meet the specific needs of photography. Select a digital camera so now more and more people photography, but digital cameras compared to conventional cameras, there is still some lack of total, of which digital camera is a typical time lag problem.
