Many friends might be in the location of the 7 D doubts, believe that since there is a digit type, why
not the picture? At this point we might as well look like this: 7 D is a size and 50 D camera, but the
similar properties to higher than 50 D; 7 D and 5 D Mark II, the same rating Canon want this two
cameras in the service of a high-end users pairing.
5 D Mark II in the format of the characteristics of high quality imaging for those wide Angle lens, and
special use to the needs of commercial photographer. EOS 7 D with high speed and even pat, new
focus module, excellent reliability, exquisite fuselage and more abundant lens selection in the pursuit
of these properties, in high-end customers. And, in addition to photographic Panasonic DMW-BCF10E
Charger components smaller,
the 7 D in all aspects of more than 5 D configuration completely Mark II. The arrival of the 7 D, let
EOS product faction of the rich showing unprecedented situation.

Fuselage design
7 D the fuselage of a smooth continuous above the surface modeling, the size of the fuselage and
50 D, shell is using similar with electromagnetic shielding function and magnesium alloy, in addition, 7
D and used the 1 D series camera the same coating process. The 7 D at the bottom of the hole is
placed around a tripod by rubber, installed in yuntai the stability of the higher.
Vision rate and magnification 100% of the viewfinder
7 D viewfinder vision rate reached 100%, this means that through the viewfinder observed scope
and actual photography to the scope of the are basically the same. In addition, the 7 D viewfinder
magnification is 1 times, this shows through the viewfinder with the naked eye can be directly
observed basic same image size.
7 D point screen in addition to display 19 of the automatic focus, still can according to the needs of
the photographer shows grid lines, center-weighted average metering or spot metering round,
three dimensional electronic level and other projects.

New af system
7 D has 19 automatic for the 19 automatic focus, focus on all adopted four-arm sensors (four-arm
sensor is refers to perpendicular line and the horizontal line for testing sensors are arranged, such
arrangement four-arm benefits can be adjusted for is body shape and texture and coke influence of
failure to the minimum degree). And because the 19 to focus all use corresponding F5.6 beams of
light sensors, therefore, can not be different lens diameter different effects, let all EF lens of
autofocus performance are able to make full play.
In addition, focusing on the central system, which has three horizontal line detection sensor is two
columns crisscross is arranged, through the double checking reduce error detection. Take off in a
big focus (grammaticalization) state, the crisscross is arranged in two columns focusing sensors will
common action to improve the detection be taken the speed of the body. Not only that, the use of
high frequency, in addition to the central government to the focus will be F5.6 beams of light
sensors is corresponding to the arrangement outside, still in its inclined direction with the
corresponding F2.8 on beams of light sensor, thus constituted four-arm central eight to double the
af sensors, can be more precise focus. This is because F2.8 beam F5.6 beam than the area is large,
testing of the baseline length also use longer and be able to detect subtle and the ability of focal
error.
7 D used to detect illuminant colour of the 63 area, af sensors double metering system can be
combined with the testing data of the metering sensors for different light source and caused the
focal error compensation.
5 to focus choice model
7 D 5 kinds of automatic mode choice to focus. Manually choose mode in addition to include "single
point autofocus" outside, still have focus range than single point autofocus focusing more small
range af "and" designated when the subject from automatic for selected body focus on, the
selected to focus the up and down or so to focus will be automatically auxiliary focus "automatic
focus on expanding" af area such as choice model.
In addition, "regional autofocus" to focus the 19 a divided into five area, can choose from among
them to focus area, the focus will be using the selected af area to be taken to focus all body for
testing. So in the priority of the composition of while, can be adjusted accurately capture body. In
addition, "19 point autofocus" can also use the central eight to double cross, all 19 points four-arm
af sensors to be taken body was catch.
The more strong AI SERVO
Able to track objects in motion of the SERVO AI (artificial intelligence) SERVO af function in the 7 D
have made a dramatic increase. Not only for and be taken of the distance between the body, still
can choose "19 points in af" or "regional automatic focus on the image," inside (af area, the use of
regional automatic focus to choose area) and direction of the parallel mobile unobtrusive body, and
can track to be taken for volume catch.
In addition, the 7 D can also set the AI SERVO activated when the automatic to focus, so as to
reduce the probability of deviation and focal position. In "19 point autofocus" mode, when the
subject of body movement from the automatic choice not to focus, other automatic starting to
focus will be on the track. At the same time, the current to be taken body tracking of autofocus
points in the viewfinder display inside.
The more careful "af area choice"
With automatic focus system, 7 D, all kinds of functional focus system configuration program also
become more meticulous. 7 D can in horizontal or vertical hold the camera set respectively
automatic focus mode choice and use regional automatic focus on (area) position. Use this function
words, even if ChiJi change direction, also need not reset af area, can change in ChiJi direction to be
taken immediately after the body to shoot.
In the longitudinal ChiJi, 7 D can use different according to user habit (the handle on or next)
setting respectively. In addition, through custom control buttons respectively, the four kinds of af
related function (choose af area selection mode, artificial intelligence servo tracking sensitivity,
artificial intelligence servo 1/2 image is preferred, artificial intelligence servo af tracking mode) to
register. After registration, but also through the button operation (of the depth of field preview
button or lens autofocus stop button) when shooting in a key finding these Settings quickly good
features, 7 D have such can according to demand when they need to change the Settings
temporary automatic focus features. Not only such, EOS 7 D is also carrying "automatic focus,"
fine-tuning "cannot carry out automatic focus the lens drive" when many af related custom
function more exquisite, can reflect the photographer's intentions.
3 d electronic leveling
Electronic level can detect camera level and the before and after tilt, 7 D is Canon SLR cameras in
the first launch three dimensional electronic leveling of the camera. 7 D camera in the direction of
the perpendicular to the axis with the two were used in the detection of tilt and tilt the camera level
before and after the acceleration sensor. Can with minimum 1 ° to the direction for the unit, the tilt
testing.
Level of two kinds of the display mode in using the optical viewfinder, shooting, able to use
automatic to focus on the horizontal direction + 6 °, plus or minus 4 ° direction before and after the
tilt of the camera to display (horizontal shooting). Also can use LCD monitors displayed on the back
(in the film, the real-time display of short films and ready to shoot state). At this time will show
graphical level, capable of 360 °, horizontal direction + 10 ° before and after the tilt testing. And the
general electronic leveling function is different, it also can be the direction to before and after the tilt
of the camera for inspection.
District 63 metering sensors double
The 7 D district 63 sensors can double metering except with the previous sensor of the evaluation
of the same metering metering, metering, local center-weighted average metering or spot metering
(the central point), central focusing average metering, but also in the wavelength detection RGB
color of the wavelength and B R color measurement function, and according to the data from the
red can improve it produced under exposed. In addition, 19 automatic focus corresponding to a
corresponding metering, so can reference the regional focus click brightness distribution and other
ways to receive the out-of-focus quantity and then calculated the exposure value. Even in
brightness difference of the big scene, can also get more small deviation stable data. Because
exposure compensation to expand the scope of plus or minus 5 EV, so in all kinds of automatic
exposure mode more handy.
Intelligent comprehensive flash system
7 D built-in flash has built-in flash signals launch function, can be through the wireless signal control
external flash flash. Built-in flash of light emitted by radio signal pulse can be, and have the function
of the wireless affiliate 580 EX II, 580 EX, 430 EX II, 430 EX, 420 EX and original signal transmission
Canon flash, in order to achieve one or more of the flash only flash from the machine flash. In
addition to control external flash and built-in flash, still can set the amount of light both than, can
choose only external flash flash or both flash. Affiliate external flash as long as have wireless
subordinate function, even if there is DuoZhong model mixed use flash can control.
In addition, hot on the boots if installed directly compatible with built-in flash signals launch function
to turn off the light flash 580 EX II, 430 EX II, etc, also can achieve if E-TTL II to be automatic flash.
Can use flexible af auxiliary light, image size to be automatic zoom control function (270 EX except),
flash exposure lock function, color temperature, high speed information transmission function

The trial 7 D I choose in 798, when the shooting took used is the set of head 18-135 mm. The trial
when I brought a and 7 D class of similar nikon D300, mainly to see both in the difference on the
imaging. After filming contrast images of the 7 D I feel a lot better than the D300, 7 D photos style
than the D300 options imaging adjust well done. The options
Born for creator-Canon EOS 7 D
7 D increased a lot of new features, and some small change. A critical position although changed,
but nothing is convenient place. The 7 D the new format conversion key RAW in a lot of moment
are very useful. In the trial, I found that I 7 D focusing speed and accuracy are improving a lot, and
it's even pat speed is high. In addition, the original Canon camera aperture in the change to the big
wheel and dial switch gears, 7 D will have a special switch.
Here also mentioned a very interesting, is the function of the 7 D in the two button will appear next:
INFO after a confirmation composition of function. Level If the current level, so the composition is
you can see two lines into green, this is very helpful in composition is sufficient to see that Canon 7
D in the design of the very delicate, the photographer need thought of.
7 D in the shot of the time for people feel very comfortable, and soon the focus speed and good
imaging let this shooting very smooth. At the same time machine 18-135 mm lens when use very
convenient also, this only lens cover from the wide Angle to the telephoto focal length, though not
red circle lenses, but very practical, wedding dress and photo shoot when enough used.

Now I shop is 1 Ds Mark II and 50 D with, I've always wanted to add a camera. 5 D Mark II are
good, also accord with the location of the studio, but I think it and 1 Ds Mark II distance, and no in
5 D, 5 D Mark finding II and 50 D between left a large section of the "price", but also is so blank,
from 7 D release I am interested in it.
7 D after I get it and 50 D compared the, from appearance, don't look carefully, 7 D and 50 D
make no difference. As a professional photographer, I'm concerned about is not the type of
industrial design, but the functions of the camera is raised, whether the camera, if you can give
practical work of photographer bring convenience.
7 D and 50 D in operation on basic same, just 7 D the power switch moved to model the rotary
table below. In imaging, I think 7 D imaging style and 50 D like and keep the Canon consistent
downy style. Be worth what carry is, 7 D in high under the mode noise from the control level is
quite good, this time I use ISO800 took a few shots of the guest, the effect is good, have high
practical mode can greatly improve the success rate of use of field light shooting.

7 D automatic white balance to the color reduction very correctly, in the light of mixed shoot also
won't partial color. 7 D to the airframe of a very practical "RAW + JPEG" button, the buttons on
the left side of the in the viewfinder. When shooting if feel to the one house, press this button to get
RAW + JPEG photos, and click on it and take JPEG. Even if forget, the top of liquid crystal screen
quality column will also hint at present in RAW shooting flashing pictures.
The 7 D center-weighted average metering or spot metering very accurate, it points to the
viewfinder measurement is to focus on the position of the square of the measured points. That is,
where to focus is measured in which, the exteriors shot and in the light of the mixed and disorderly
environment shooting are quite useful.
The trying out for I did not find model but direct the marriage gauze of guest take, my this on the
guest is very young, don't want to take the traditional photography, like some things. Personality
So the outdoor scenes I recommend guest in the 798 art district and lukewarm yu river to shoot.
A photographer friend told me about, when the shutter speed at 1/60 SEC when filming will basically
with virtual, in order to avoid this phenomenon, he is now even with the method of shoot three
zhang, three inside must have a clear. This makes sense in filming, before I went to plan to use the
method of dynamic photo shoot some, conveniently also try 7 D has even take the performance.
In 798 the filming this picture was taken from the boy behind girls come running and jumping up
attitude, then even holes come in handy. I put the focus way is adjusted to the AI (artificial
intelligence SERVO SERVO automatic focus), in the backlight with 1/500 seconds under the shutter
speed (the faster shutter speed, even pat quickly). For the camera, characters run the reaction of
the SERVO AI to very fast to ensure that definition, clap a few photo, virtual, of course, but jumped
up a few pieces of almost all very clear, very fine, action decomposition that took even really fast,
the precision of the camera focus is very high.
Lukewarm yu river in take this picture of the test is not only the camera's even take ability, and I
think the 7 D a spotlight away from the machine-flash. The 7 D from machine flash can only remote
Canon original flash light, also can be more remote control only original flash Canon.
Shooting the picture it was late afternoon, take the light use is the Canon 580 EX flash light, with
characters I on positive lighting. The intensity of the light in the dark parts to control the sky have
layers. In the 7 D flash control menu, select the outer flash control, play flash on top as frequency
band launch, very convenient. Brightness with aperture and strength can control mode, the
technology Panasonic Lumix DMC-FZ20
Charger is, just before now is loaded in the fuselage of a camera. I think if the function to popular
and widely used by everyone, then those who fight with heavy shoot the lamp of the photography
assistant who will from heavy manual labor liberate, one or two Canon external flash camera with
respect to Ok, photographer also need not can consider whether to forget to take or the
occurrence of the flip-flop flip-flop in half the time take this embarrassing situation don't have
electricity.
Tip:
7 D at the key new changes
(1) the power switch is designed in the machine left top. (2) the switch machine back in a machine designed to lock the keys back dial the dish. (3) the new "in the upper left corner back machine RAW/JPEG" button, its function is in JPEG or
any RAW format, each as a the key, can will this time images captured the save for both formats. (4) the "Q" button for EOS 7 D speed control buttons, press the button in the information display
screen will activate options, then can be set. (5) the dial machine beside his plate "M-new Fn" custom function keys, can be in the menu function
definition, in some operating setting process, according to the prompt of the interface can also use
