No change in the percentage, but detailed maintenance is the order of the day from the EOS 40D to the 50D. The tried and tested chassis made of magnesium alloy has not changed as much as the dimensions or the weight. The camera is superbly hand-held and can hardly be improved from an ergonomic point of view. However Canon could not decide to seal the housing comprehensively against dust and splash water. Corresponding measures have been taken only for the memory card and battery pack, which is already known from the 40D.
Proven operating concept and many exposure programs
Also, the optical viewfinder with an effective magnification of 0.56x is not good for a surprise. Pleasingly, however, the EOS 50D remains one of the few SLR models where you can change the viewfinder discs as needed. The Ef-D standard diffuser can be replaced with the Ef-D grid and Ef-S for manual focussing, all at a price of 25 euros. An innovation is to be noted at the connection panel, which is hidden on the left side of the housing under two rubber battens: In addition to USB, Hi-Speed, and Video-out connectors, there is now an HDMI output to transfer high-definition digital images to a TV or beamer.
Recording data on the LC display and TFT monitor
The big "thumbwheel" at the back of the operating concept remains the focus of the control concept - very handy when navigating the menus and changing the picture when you are in the playback mode. In addition, there is a small joystick (4-way switch), which facilitates navigation in the menus. For example, With the joystick between the horizontally arranged, nine menu extensions back and forth. You can select between the vertically arranged entries with the joystick or thumbwheel. In the submenu of an entry you can either press the joystick or the Set button on the dial. Each sub-menu can be viewed without scrolling, the fonts are comfortable.
Monitor and live view significantly improved
Individuality promises the last tab in the menu ("My Menu"): There you can store up to six menu items, which you then have in the fast direct access - practically, because the search times in the menus thereby significantly reduce. Compiling "My Menu" works with the Register function. In addition to this, you can assign a menu page to the function button, which is often required. The mode dial for exposure programs offers full, program, time and aperture auto-selection, supplemented by a manual mode, six scene programs and A-DEP as a special program for Maximum sharpening depth. Via C1 and C2 the user can retrieve previously saved camera profiles, while CA stands for a fully automatic system. In the corresponding setting menu, a slider for the exposure correction and a second slider for the exposure correction can be found. - Move to the left means "blurred background" (= large aperture), to the right means "sharp background". This automatic version is intended to appeal to user groups who are not satisfied with the full automatic but do not want to go too deep into photographic technology. A low trigger delay including AF time has always belonged to the strengths of the Canon SLRs, and also the EOS 50D must With 0,28 / 0,26 s at 3000/30 Lux not hidden. The Nikon D90 as the main competitor is at least slow with little light with 0.60 s much slower. In the home, however, there are still faster cameras, including the predecessor EOS 40D with an excellent 0.14 / 0.21 s. The camera has won at the picture sequence time, which is now 6.1 images per second, at least on the paper The EOS 40D is slower at 5.8 B / s. The on-delay is pleasantly low on both models with 0.3 s.
Improved noise and dynamics
On the top of the camera is the LC-Display typical for the model series for the display of recording data. The display has four buttons to access the following parameters: ISO setting and exposure compensation, AF mode and drive (single / series, self-timer), white balance and exposure metering method. In addition to the 35-sector matrix measurement, the EOS 50D allows the variants to be center-weighted-integral, selective (approximately 9% of the finder field) and spot (3.8% of the finder field) Has added: A push on the joystick opens a display panel on the monitor in which camera settings are not only visible but can be changed directly. To do this, you can use the joystick to navigate to the relevant field to operate with one of the two command dials ("Quick Control Screen"). In addition, different camera settings are shown as an overview, even after pressing the Info button, but can not be modified there. A custom button has been donated to Canon (Standard, Portrait, Landscape, Neutral, Natural, Monochrome and Custom 1-3). These can also be changed in parameters such as sharpness, contrast, color saturation and hue, and software filters and toning effects can be activated in monochrome mode.
The size of the monitor has not changed with 3 inches (7.6 cm) diagonal, but the resolution. This is now 307,000 RGB pixels, three times as much as before. The viewing angle is horizontal and vertical at 160 degrees so that the subjectively perceived color reproduction changes only slightly at unfavorable viewing angles. The brightness of the monitor can be adjusted in seven steps, while a gray scale, which is shown next to the sample picture, makes setting up easier. The quality of the new monitor not only benefits the image display, but also the live view display - especially in the enlarged live Image manually. For this purpose, a magnifying glass magnifier of 5 or 10 times can be connected. For automatic focus, the camera offers three options: Quick, Live, and Live with Face Detection. When set to Quick mode, the camera uses the phase AF already known from the EOS 40D with nine cross-sensors, including mirror-beat and dark pause. The Contrast AF (LiveMode) works without this disturbance, but much slower, and the corresponding measuring field can be moved freely in the image field using the joystick.
With the LiveView with face detection, the AF field jumps to a face in the image field to focus at this point. At the same time, the exposure is optimized. In the live image show can be a histogram and two different line raster. If the exposure simulation is also activated, you can see how the image becomes brighter or darker when using exposure compensation or manual aperture adjustment. By pressing the dimmer button, you can control the depth of sharpness in the Live View mode on the monitor, without darkening the image as it does with the sharpening depth control in the optical viewfinder.
The CMOS of the EOS 50D records pictures with a nominal resolution of 15 megapixels, in Photoshop an image file of 40.23 x 26.82 cm at 300 dpi opens. In addition to six JPEG quality levels, the camera offers three RAW versions, including sRAW1 mode with 3267_x_2178 pixels and the new sRAW2 mode with 2376_x_1584 pixels. In addition, RAW and JPEG can be combined in all variants. The corresponding menu page is very clear because the RAW types are listed in one line and the JPEG levels are listed in a second line.
The current DiGIC-4 processor with a depth of 14 bits is responsible for image processing. It supports the UDMA mode of modern memory cards, which allows a faster data exchange between the card and the image processor. In addition, it has sufficient power reserves to automatically correct the vignetting of the lens. The measured resolution is a maximum of 1327 LP / BH at ISO 100 and 1191 LP / BH at ISO 1600, which is expected to be significantly higher than that of the EOS 40D with 10 megapixel sensor and DIGIC-3 processor Values of the EOS 40D (maximum 1106 LP / BH). The 12-megapixel camera Sony Alpha 700 is nearly equal to ISO 800 in this discipline - or would it be at least if the Kurtosism measurement did not exist. With a texture loss of a maximum of 1.2 to ISO 1600, the new Canon cuts significantly better than the Sony model with a maximum of 1.8, but is not as good as the Nikon D90 (through 0.1). In comparison to the EOS 40D The new one is less clear, which is clear at ISO 800 and is even more pronounced at ISO 1600 (VN 1.5 vs. VN 2,7)
The EOS 50D has also increased in the dynamic range, which is now consistently 9,5 stops up to ISO 800 and falls at ISO 1600 only on 9 screens. The EOS 40D can keep up to ISO 400, but with ISO 800 and 1600 but a diaphragm in arrears. Switching the EOS 50D to the "tonal priority" option increases the dynamic by half the aperture. The noise remains practically unchanged, but the loss of texture increases to 2.5. The new Canon reaches 55 points for the picture quality at ISO 100 (53 / 52.5 / 49.5 points at ISO 400/800/1600) ). The result can be seen, even if the Nikon D90 with 58.5 / 58 / 56.5 / 56 points in the class up to 2000 euros remains the leader.
