Who is the best partner 350D? .Brand CF card limit testing.

Canon 300D <P> must have a lot of users will have the following experience: Although the 300D's 2.5fps continuous shooting speed is acceptable, but the maximum number of sheets only four shooting, greatly limiting the use of continuous shooting. .This is because the 300D to read data from the CCD and stored into the cache, not to digital processing and JPEG compression, and only write to the memory card when it is carried out within the JPEG compression. .So even if the 300D shot using the JPEG, and RAW can only get the same number of sheets maximum burst, coupled with the internal signal processing is relatively slow, so the bottleneck even with high-speed CF card can not be relieved. .</ P> <P align=center> <center> </ center> </ P> <P> but Canon's new EOS 350D is different, due to the use of DiGIC II processor, the internal processing speed has been particularly .enhancement. .350D CCD data while reading can be digital processing and image compression for the JPEG format, stored in the cache is a good JPEG files have been compressed, so in RAW format can store only 5 of the cache, but can .JPEG format stores 14 photos. .And in order to improve the speed of the memory card using high-speed storage cards, will be able to continuously remove the photos in the cache, make room in preparation for the next shot. .</ P> <P align=center> </ P> <P> Therefore, the use of high-speed CF cards as possible, we can increase the maximum continuous shooting EOS 350D books, but also in the unit time of the shooting will increase the number of sheets .. .In order to explore the EOS 350D the following limit shooting performance, several of our commercial mainstream memory cards were tested. .</ P> <P> test project </ P> <OL> use the LARGE FINE format the number of non-stop shooting RAW + JPEG shooting 5, the camera records the action within seconds 30 seconds LARGE FINE format .number of shots </ OL> <P> the shooting if the composition has changed, then the corresponding photo file size will have changed, it will affect the test results. .So we EOS 350D test fixed on a tripod, using the same composition, and the lens focus mode switch from automatic to manual focus mode to remove the autofocus delay. .</ P> The test photographs <P> addition, even if all fixed, but the shooting still slightly different, so the test results are still only a relative value. .The shots used for the doll in front of white background from the screen is relatively simple. .Basically not taken the test in a long photo size 2.34MB, the 350D is relatively small. .If you shoot the picture is relatively complex and ISO sensitivity is increased, then the file size will definitely increase and reduce the number of sheets of continuous shooting. .</ P> <P>.
