Canon Digital Rebel T1i Review

canon rebel t1i reviewLike all current Canon EOS DSLRs, the Rebel T1i generally turn on instantly and is all set to shoot by the point you’ve moved your finder from the on/off exchange signal of the shutter release. Other operations are fast too, without doubt helped with the new Digic IV processor utilised in the Rebel T1i.

The canon rebel t1i review Digital SLR specifications list continuous shooting at approximately 3.4 fps for up to 170 large/fine JPEG images or up to nine RAW images a single burst when utilizing a class 6 or higher SD or SDHC memory card.

In actual tests having a class 6 SDHC card, your camera set to ISO 100, manual focus and manual exposure which includes a shutter speed of 1/500s, I measured a consistent shooting rate of 3.37 fps when capturing Large/Fine JPEGs. In RAW mode I measured 3.36 fps for 10 frames. Then a buffer filled as well as frame rate dropped to 0.63 fps. When shooting RAW+Large/Fine JPEGs the continuous shooting rate was 3.2 fps for 3 frames, then dropped to 2.3 fps for one more two frames and finally to around 0.6 fps as soon as the 6th frame in the event the buffer filled.

As with the EOS 50D, the use of high ISO noise reduction results in a reduction in the volume of images that can be residing in the buffer, presumably because the fact that image processing power required for noise reduction holds back writing from the buffer towards the memory card and the buffer memory fills up faster.
Controls

The control layout from the Rebel T1i can be quite much like previous models. The T1i person is virtually identical to the XSi body in addition to a few holes (with the microphone and speaker).
A common obvious change is the colour of the key control dial proceeded to go from black to silver. The chief control dial has a new setting “CA”, which means a “creative auto” mode. That is somewhat like the full auto mode, but permits you to save some custom settings. It will save you flash mode, picture style, image brightness, single shot or continuous mode, image recoding quality and bias exposure toward smaller or larger apertures. Once saved, these settings will be remembered anytime you end up picking the “CA” mode. In the event you don’t change the settings from default, they will be exactly like the conventional “full auto” exposure mode.

The 13 shooting modes available are: A-DEP (auto depth of field), Manual, Aperture Priority, Shutter Priority, Program AE, CA (creative auto), Full Auto, Portrait, Landscape, Close-up, Sports, Night Portrait, Flash off and Movie.

Control buttons and dials around the rear from the camera are almost comparable to those on the XSi (450D). The buttons and switches have been in the same place but a few have different functions. The direct print button now also can the movie “record” button. Because of this the White Balance button needed to be reassigned and yes it’s now the top button of the 4-way controller. There's no longer a metering mode button, metering pattern now being selected via the menu system or you can get on the same options by pressing the “set” button part way through the 4-way controller and selecting the metering option with the screen display.

Like additional Digital Rebels, the T1i don't even have the trunk “Quick Control Dial” used on more pricey EOS models and yes it doesn't need a high mounted LCD to display camera settings. A corner LCD is utilized to show off all camera settings.
Image Resolution

The pixel count of the Rebel T1i is 15.1MP, much like the EOS 50D as well as the two cameras show similar resolution. It’s slightly above the resolution you have with the EOS 40D, Rebel XSi and Rebel XTi, but it really’s never a “day and night” difference. Until you earning large prints, the real difference in resolution will not be noticeable.

I checked out images on the EOS 40D and Rebel T1i (because we were looking at essentially the most similar cameras I needed offered by time on this review). Going through the 40D (10.1MP) to your T1i (15.1MP) should theoretically give you linear resolution capability increase approximately 22%. In practice, the visible difference is a lot less than can certainly it wouldn’t be worth upgrading from an XSi or XTi just by the slight development of sensor resolution.

One thing to assure of when you compare resolution between cameras is always that the images from both go although same couple of sharpening and noise reduction parameters. As an example, as I received it, the Rebel T1i was set on the “neutral” picture style. This applies no sharpening to JPEGs. The “standard” picture style applies a sharpness setting of 3. The “neutral” picture style really is for many who expect you'll do their particular image tweaking with a computer. The JPEGs from the T1i looked somewhat soft using the default setting. That isn't a camera “fault”. Most digital images can usually benefit from sharpening, whether in-camera or during post-processing. Some cameras apply a good deal, some apply slightly by default. It’s nearly an individual to decide what looks wise to them.

Shooting in RAW and after that applying precisely the same sharpness and noise reduction in canon's supplied Digital Photo Professional (DPP) conversion software is the most reliable means of comparing images.

I checked out the resolution of EOS 40D and canon rebel t1i review images alongside each other using several lenses at a number of different apertures and processed the photographs using DPP with similar parameters. The Rebel T1i images showed better detail in each case, though the difference was pretty small. If you can't were making very large prints or severely cropping the images, the visible difference wouldn’t be noticeable to most viewers.
