Camera in these few years have developed rapidly [link widoczny dla zalogowanych], the performance parameters are to be constantly refreshed. From the year of 500 million pixels mainstream has soared to 10 million instant over zoom, sensitivity and so on are also rising. Here we look at what are the main parameters of change.
 Pixels
 Relatively intuitive, scalable and easy to upgrade the pixel will still be upward trend. From 10 million to 12 million pixel home products will gradually become mainstream [link widoczny dla zalogowanych], started the pixel products from 7 million to 8 million to move closer. However, domestic consumers of these small digital megapixel race really has not been so concerned about the, it touches on fire today more and more digital SLR cameras into the new positions various manufacturers.
 Card machine compared to a digital SLR is more professional [link widoczny dla zalogowanych], many photographs need to zoom out, has good reason to significantly upgrade pixel configuration. Today, many high-end digital SLR concentrated in the 10 million-pixel level, and may be about 16 million products gradually replaced, and those who challenge the top professional digital SLR will be more than 20 million pixels.
 Lens focal lengths
 Today's consumers have a better understanding of optical zoom and digital zoom, the difference between the usage of digital zoom is very low, many people buy cameras basically do not care about this parameter, the more focus on optical zoom on. Now portable telephoto cameras generally have 7 to 10 times optical zoom, should also have some room to rise, while in the high-end telephoto machine, up to 18 optical zoom, due to the longer focal lengths when the actual shooting jitter The more severe, reducing the practical value of telephoto. What major manufacturers may slow down the pace of progress, if not more powerful anti-shake function, before the R & D, advises consumers not to buy or zoom too much product.
 But in fact by looking at zoom lenses can not fully understand the practical perspective, if a camera's lens is used 28 ~ 200mm focal lengths, while the other branch was used 38 ~ 380mm, optical zoom when watching They are nominal 10x optical zoom, only when in actual use will be found a good wide-angle shots and another good at telephoto. Therefore, in addition to interest in buying time zoom, the camera should pay more attention to what the actual focal lengths, and then shoot for their own preferences, choose products more suited to their style.
 Sensitivity
 Now a common portable digital cameras have ISO1600 or ISO3200 light sensitivity is not nothing special to do. Higher sensitivity has occurred in some products, but in the digital SLR has already been exceeded. Each year, the image processing engine upgrade should be will be, especially in high-sensitivity has experience handling the brand, increase the engine speed in addition to improve the camera beyond the most obvious is the more effective control of noise. The highest consumer digital cameras also have the actual increase in sensitivity, ISO400 or even higher sensitivity would greatly enhance the practicality.
 Storage media
 Recent years, the fastest growing storage medium can be said to SD card, and overnight from SD to SDHC, suddenly become infinitely large storage capacity, 32GB of SDHC, 16GB memory stick, 48GB of CF cards have debut These high-capacity memory card prices are very expensive, relatively far from the ordinary consumer. Consumer interest is also mostly in the low-end speed, such as the product between 1G to 4G, its price is quite close to the people. Previously sent to a memory card compared to the equivalent of 100 yuan to 200 yuan less different, with the price of lowering the memory card, and now a second-tier brand of 1G memory card often only tens of dollars, consumers can inquire about the price of memory card to avoid unnecessary losses.
