The obvious difference between the image sensors SLR D90 and Canon Rebel T1i is 15.1megapixels and 12.3MP respectively. With these data and the application may think a little ', many people lead to the conclusion that the transaction Rebel T1i probably better.

Unfortunately, data on exceeding customer radar, which is simply not correct. There are better image sensors (Canon 40D SLR), which are used in planningStage.

I'm sure you've learned in some of my other discussions, such as megapixels are not necessarily the most spectacular shots. The image sensor must be designed to cope with more megapixels.

The sensor of APS-C of Rebel SLR T1i that is used is actually a little 'smaller than the DX-type image sensor with Nikon D90 DX. Of course there are different approaches more pixels than a smaller sensor to achieve. With smaller pixels, timpani and closer than ever.What were talking about is in effect, a different measure of density of pixels. This is not a specific one can find many branded products for the packaging Canon Rebel T1i. Density of Canon Rebel T1i is 4.5 million pixels per square inch, but the D90 is 3.3 megapixels per square inch.

Crowded pixel is a nuisance, but there's more. How can you go in search of additional lenses, more megapixels means is provided which generally fall more money for betterPrice lenses. The goal is a work of high-megapixel digital SLR is designed for a higher resolution, and almost always charge.

Strangely, the objective, which is usually expressed's (EF-S 18-55mm f/3.5-5.6) from the manufacturer with the Canon Rebel T1i, not one that is good in the management of large appliances format megapixel resolution is appropriate. I know it is a bit 'more money, but the Canon 18-200mm AF-S would be a better target for T1i.

IfIt is not enough, you might be interested to know that the high pixel density may affect the performance of ISO, diffraction and dynamic. I do not know how to do it for you, but I'm beginning to believe that it is always less megapixel Nikon D90 12.3MP more money, better treatment for my bank account.

An old measure of image sensors RAW data is provided by DxOMark. DX-O-Mark has the Canon EOS 50D, which has experienced the image sensor is identical to that T1i and employssupports my hypothesis above, that the Nikon D90 produces better image quality. The Canon 50D test should test very close to the Canon Rebel DxOMark T1i once it is presented.
