The camera world is all about comparisons. If you look at user forums, you will see that each camera is compared to every other camera that has similar features.
And of course, the Canon - Nikon debate is at the top of many of these arguments.. er.. comparisons.
Most recently, there is a discussion about the merits of the new Canon Rebel T2i (aka 550D) versus almost any other model including some of its own siblings. However, with this writing, we will take a peek at some similarities and/or differences to compare the Canon Rebel T2i vs the Nikon D90, since the Nikon also boasts having video capabilities, as does the Canon model.
At the top of everyone's list is the sensor size. In this case we compare a brand new (for the Rebel line) Canon 18 megapixel sensor with a Nikon 12.9 megapixel sensor.
When we discuss pixels we generally think that more is better. However, this is not always the case. When you get to a certain level in the pixel count, you need to take into consideration the quality of the pixels rather than the quantity. Canon has added an additional 3 megapixels to the same size sensor found in the T1i, and they have done a good job of re-engineering the pixels so that they are of better quality. This has improved the image quality as well as the possible image size. But how many people actually print a photo that is 17 x 11.5? This is the size you could print at a resolution of 300 ppi (pixels per inch).
In comparison, the Nikon has a sensor size of 12.9 megapixels. Add to this a sensor that is actually physically larger than the Canon sensor, and you have the possibility of an image that prints with better quality.
This is very highly technical in nature, but suffice it to say the the Nikon D90 will produce images that are quite large and are considered by some to be of better quality than those produced by the Canon T2i. Now, that information is based on some very discerning technical evaluations. To the casual viewer, there may be no difference at all between the two.
Next, let's consider the movie mode, since this is the biggest marketing point for the new Canon. Right up front, there are no critics that will not admit the movie mode is superior on the Canon Rebel T2i compared to the Nikon D90. You can capture video at a whopping 1920 x 1080 which views beautifully on your HDTV. Add to that the new stereo sound input and the ability to attach an external mic and you have some pretty impressive video. The Nikon will capture 1080 x 720 at 24 frames per second. Not quite as impressive, but still good quality. Now, the only drawback to the larger format is the memory required in the camera and on your computer once you download. So, is it really necessary to go for that large format video? Your choice.
Another feature that you may want to consider in your choice is something called Live View. Both cameras have this feature, but the Canon has added something not available in the Nikon. Actually two things. First, you can turn on a grid that divides your screen into thirds. This is a handy feature for composing your photos using the Rule of Thirds to get a more pleasing photo layout. Additionally, with the Canon, you can zoom in Live View to 5x or 10x size to check the focus of your shot. You can only imagine how much this can help eliminate out of focus shots.
There are other features to look at, and I suggest that you do before making your choice.
A major consideration is whether you already own a previous model of either brand. If so, you will definitely save money by simply upgrading to a newer model so you can continue to use your lenses.
However, if you are buying your first Digital SLR camera, you can't go wrong with either model. Image quality leans toward the Nikon, but the Canon (as with all the former Rebel models) is recognized as having superior image quality as well..... Read more
Most Helpful Customer Reviews of Canon Rebel T2i
PERFECT!, March 11, 2010
his review is from: Canon EOS Rebel T2i 18 MP CMOS APS-C Digital SLR Camera with 3.0-Inch LCD and EF-S 18-55mm f/3.5-5.6 IS Lens (Electronics) Whether you're new to the world of DSLRs, or are a seasoned photographer who wants to try your luck at video, the Canon Rebel T2i is perfect. I've had nothing but great experiences with it so far, and highly recommend to everyone.
Other than the T2i, I own (and primarily shoot with) the Rebel XS (1000D), and also have extensive experience with the Canon 50D. While my XS still serves me very well, I wanted to get an SLR with video capabilities since the release of the T1i. After finally saving up enough for the T1i, I really lucked out that Canon announced the T2i, which has even better features! I am lucky enough to finally have it, and want to share my experiences, and how they compare to my expectations
==================
OVERALL IMPRESSIONS
The camera is very small and light. It is not weather-sealed or as durable as some of the more expensive SLRs, but it doesn't "feel cheap" in my opinion. It features a 3-inch LCD (compared to the Rebel XS's 2.5 inch screen), which also has a very high resolution. It looks lovely! Auto-focus is fast, and I've been very pleased with the quality of the pictures and videos I've taken so far.
==================
PROS
IMAGE QUALITY: I feared that cramming so many megapixels onto this sensor, there would be a lot of image 'noise' (the megapixel myth). This thankfully hasn't been an issue, and I've been very pleased with the pictures taken with this camera! Aside from White Balance issues (see below, Cons), image quality is pretty good!
VIDEO: Some people have disparagingly said that Video on DSLRs is just a gimmick. I disagree. Based on sample clips I'd seen on YouTube, I was excited about getting an HDSLR, and while videos are sometimes shaky if you don't have very steady hands, a tripod eliminates those concerns. Audio quality on the T1i was criticized by many, but the T2i has a microphone input jack, which allows you to connect a mic. I don't yet own one so can't comment on that feature, but will update this review if and when I save enough to try this feature out. Additionally, this offers improved recording options, including higher fps (frames per second) than the T1i, which technically offered "true HD" recording of 1080, but only at a choppy 20 fps.
LOW-LIGHT PERFORMANCE: I am much more impressed than I expected. My Rebel XS could go up to ISO 1600, but would perform pretty poorly there. This not only can go up to a significantly higher ISO level, but performs much better. Less image noise means you have to waste less time editing your pics, and many more keepers!
SDXC SUPPORT: Only own SDHC cards up until now, but it's great to know that this supports the next generation of flash storage, which means you'll in the future be able to hold many more pictures than currently available.
CONS
NOT A FULL-FRAME SLR: This is not a full-frame SLR like the Canon 5D Mark II, and the APS-C sized sensor results in a crop factor (1.6x), and doesn't necessarily provide the same image quality as the larger, full-frame sensor does. Still, at less than half the cost of the Mark II, I think this is a trade-off that's well worth it for most users.
Crop factor means that this camera, like other Canon DSLRs that have the APS-C size image sensor, will not be true to the lens's designation. A 50mm lens will produce an image more in line with 50mm x 1.6, or 80mm on a full-frame. This not only makes a difference for those who want to do landscape photography (which usually benefits from wide-angle views), but for those with unsteady hands. The general logic is that to ensure a steady shot, you need to shoot at the reciprocal of your focal length. So for a 50mm focal length, you should be shooting at a speed faster than 1/50 second for a steady shot. Keeping the crop factor in mind, you really should be shooting at a speed faster than 1/80 a second.
