Let's make a simple view of the EOS 20D menu structure. In fact, the gap between this machine's menu structure and other Canon DSLR product is not large. The following is some menu screens that appear after the MENU button. It can be found that as a mid-end DSLR product, the items that can be set in the menu are more professional. Users can set multiple projects surrounded by white balance, color space, flash mode.
This machine has a variety of options for the picture quality, and the local machine also fully supports the RAW plus JPEG output function at various resolutions. This feature not only has a lot of convenience to the post-processing of professional users, but also accelerate the process of selecting photos and quickly outputs applications.
This machine can customize the function of the button, the user can re-perform meticulous settings on the button function on the body according to their needs, to achieve the purpose of the most in line with your own habits. This feature is currently only available in DSLR products (other brands have more or less similar features), but the consumption level DC has no such design.
The following is a part of the SETUP menu of this unit, and the basic function is more familiar. We can see the 20D software version of the hand in the hand is 1.0.2. This machine also has a "cleaning sensor" function that lifts the reflective plate and exposes the CCD. I don't know when I can see the ultrasound CCD cleaning function used on the Olympus E system is applied to DSLRs in other brands. The following is the menu display of this unit, there is basically no special content.
Let's take a look at the effect of the Canon EOS 20D camera with the newly supported 17-85mm lens. First, look at the 20D performance under different ISO: For DSLR products, ISO100 and 200's picture quality is basically no suspense. For EOS 20D cameras, this machine has little difference in the number of pictures under these two ISO sensitivity, whether pureness and particle feel can reach a relatively perfect level. If the consumption level DC can also reach a very good picture of the ISO 100 or even 200, the picture effect in ISO400 and 800 is the key to the image quality difference between the consumer level DC and DSLR. Under the ISO400, although a slight red-green hierarchy has already appeared, such particles and 讯 实 相 影响 影响 画 影响 画 画 面, 面, 面, 面, 面, 面, 面,.,.....,.,................. As long as appropriate post-treatment, such as Resize and denoising, we can still get quite pure, picture quality almost 20D digital photos with ISO200 equivalent. The picture cloak under the ISO800 is more obvious, and the particle feeling of the screen has begun to be significantly strengthened, for example, this problem can be clearly seen in a large-area solid color portion of the picture. However, considering the web of the picture, after resize, the 20D picture under ISO 800 is still "available". This machine can reach ISO1600 (by opening the body menu function, the camera can be forced to the ISO3200). However, in this sensitivity, we feel that the particles and color noise in the picture are very obvious. If it is not special case, such picture quality has been difficult to have much practical use value. According to the professional evaluation results of DPREVIEW, the overall level of the EOS20D's ISO noise is lower than the previous EOS 10D. However, we don't know how many people can distinguish between these two cameras on this issue. The following is the two outdoor ISO1600 photos we have additionally taken, and such quality seems to be only applied after the network. Some of us we use 17-85 mm lens shooting in ISO400, and other settings are basically automatic and high-resolution external precision compression ratio. We have to admit that the quality of this latest 17-85mm focal length lens is basically satisfactory, but it can be clearly seen in the edge of the screen.
