Most entry-SLR! Canon EOS 550D + sample analysis highlights real shot

2010 on February 9, Canon officially announced in New York, its next-generation entry-level SLR EOS 550D (aka Rebel T2i), the new 550D will use the same 18 million pixel 7D APS-C size CMOS image sensors and DIGIC 4 image processor, 1.04 million pixel 3-inch 3:2 LCD screen, a new 63 point iFCL metering system, ISO 100-6400 (expandable up 12,800), support 3.7fps continuous shooting, and +/-5 EV in support of full HD 1080p 30/25/24 fps video capture and shooting SD video crop function 7 times zoom function, the current official body Canon EOS 550D is priced at 799.99 U.S. dollars, with EF-S 18-55mm f/3.5-5.6 IS Lens cover machine sells for 899.99 U.S. dollars, is expected to be formally listed in the early March. Earlier this year we gave you about the release of four low-end Canon camera + white second-generation lens, Canon seems to really surprise people again and again.

I believe a lot of friends on the device features is long overdue, let us take you step by step to decrypt the EOS 550D's new features bright spot, also hopes to purchase the New Year for you to give some consideration.

multi-angle look

in the EOS 500D is still a hit Hot time, Canon has come up with a surprise upgrade - EOS 550D, Canon, third paragraph and this has become a life cycle of one year of entry-level digital SLR, as previous EOS 450D, EOS 500D is the case. If, EOS 450D to the real-time viewing, EOS 500D is bringing Full HD video capture, then the EOS 550D surprise in more, it enhances the ability to shoot high-definition video, the same time increased to 18 million pixels , while the team competition, opponents of the pixels still hovering between 1200-1400 million then.

EOS 550D set new standards

EOS 550D is indeed worthy of attention, from the following list of some of its full specifications let us look forward to:

1800 megapixel CMOS sensor
ISO 100-6400 (extendable ISO 12800)

new LP-E8 lithium battery, can take 400 pictures

EOS 550D Aspect Analysis

EOS 550D biggest improvement is to use the EOS 7D on the new 19 million pixel CMOS sensor, with up to 18 million effective pixels, which is the current APS-C format camera pixel A sensor has the highest.

This sensor uses a whole The new photoelectric conversion components, while changing the pixels in front of the lens shape, making interference a smaller, higher efficiency, and this also made to further enhance the EOS 550D's sensitivity to ISO 12800.

while sensors also retained 14bit digital-analog conversion capabilities of AD, it will directly and up to 14bit in the RAW file, making post-processing will have even better results. However, this piece of sensor's performance in the EOS 7D not really the best, hope the new EOS 550D firmware can change this situation, which further reduces noise under high flu. (EOS 7D high feeling very good performance, but the ISO 400 noise began to began to have significant, but relatively high, such as ISO 3200, the noise it does not have many more than ISO 400.)

Because opening of the new sensor and image engine, the sensitivity on, EOS 550D has broader support range in normal mode can support between ISO 100-6400 sensitivity (EOS 500D is ISO 100-3200), and the expansion mode in providing the highest you can achieve ISO 12800.

higher ISO lower noise function remain, their access to high ISO noise reduction and better performance under, although it may takes longer computation time, but after all can get better images, so high ISO mode, or turn this feature it the next. In the EOS 550D at the same time provide a standard, low and enhanced regulation of three modes.

powerful metering and video capture capabilities

EOS 550D's metering system is worth mentioning, this is a new model from the EOS 7D, the introduction of the color sensor metering focus mode (iFCL), which metering pattern somewhat similar to Nikon's RGB metering, short can be brightness, white balance, color what have been captured inside. The 63 district metering obviously enough, not much more a sense (in fact has little significance).

EOS 550D offers three basic metering modes including spot metering, metering, and biased towards the central region the average metering mode, but the introduction of the iFCL mode, the meter's performance will be multiplied

Since the Nikon D90 first to come up with 720P video section of film shooting after the (no mirror digital SLR is not taken into account), digital SLR can also shoot video became the new, then the Canon EOS 5D MarkII the first to come up with a 1080P video movie shooting ability! This is true of digital photography into a new era; last year's EOS 500D features that had been introduced, so that 5,000 yuan level digital SLR also have such a powerful feature.

EOS 550D in the video shooting in the ability to further enhance, in addition to support with the H.264 format as the original 20fps frame rate, it also provides a 24P and 25p and 30fps shooting mode, which is a very good set, because the shooting 24P recording with film The frame rate is the same, so get more good sense of the kind of movie. The 30fps and 25fps PAL and NTSC formats, respectively corresponding to the TV frame rate, the benefits of natural rest is history.

In addition, EOS 550D in Purchase mono microphone, an external stereo microphone. Cutting the time taken for the 640x480 resolution video can be equivalent to 7 times digital zoom effect.

effect excellent 3:2 screen,

EOS 500D screen

EOS 550D with the EOS 500D the same as using a 3-inch panel, but the change of the screen is great because you will find the EOS 550D equipped with a screen aspect ratio of 3:2, while the 500D was 4:3, 3:2 screen clearly better performance photo shoot effect (because the camera frame is 3:2), the province again left dark.

In addition, EOS 550D's screen also coated with anti-reflective coating, even in bright outdoor situations, EOS 500D also good viewing experience, definitely not see clearly happening. At the same time in the resolution of the products have up to 104 pixels of resolution, it also means better product display.

real machine point of view, display excellent

other details and the EOS 500D the contrast between

Although the real-time viewfinder on the EOS 450D has emerged, but the functionality is still relatively limited, the EOS 550D, the Canon introduced a face-priority real-time viewing mode, when shooting their automatic performance based on the screen to focus on the face of the , this time more convenient for portrait photography.

as the market correction is a interesting new features, it can automatically adjust depending on the lens when the sensor pixel receiving optical signals of the yaw angle, so that the best, as the venue fall sensor, Canon built a lot of lens parameters, the design is definitely human .

Actually, you can see from the comparison, EOS 550D is indeed compared with EOS 500D has greatly improved, in addition to the outside as we have said before, as much as plus or minus 5 EV adjustment is definitely a bright spot, had been accused of adjustable EV Canon too low, this issue is finally resolved, of course, you can also find a small defect EOS 550D.

Although the continuous shooting speed increase to 3.7fps, but since greatly increased the size of a single photo, the EOS 550D's Continuous number of sheets but lower than the EOS 500D, which is understandable.
