The EOS Rebel T1i Has a Few Flaws

Not that it matters how much you can expect, but the D90 SLR has a tiny (12.3MP) image sensor is slightly smaller than the expensive EOS Rebel T1i (15.1MP). When these data were all you knew, then it seems obvious that the reasonably Rebel T1i, the unsurpassed SLR for the money today.

With only focus on the technical specification, the figures do not, you need to understand the big picture (pun intended) here. Bigger is sometimes better.

I'm sure you've read in a fewmy previous letter, that many megapixels do not immediately making great pictures. The image sensor is able to cope with more megapixels.

The APS-C sensor in the SLR T1i busy, actually is a bit smaller than the DX sensor of the type used by the Nikon D90. Of course, there are a few possibilities of extra pixels in a smaller box to push. With tinier pixels, and pressed closer to working together. This contributes to a less well-known specification labeled pixel density. In the case ofT1i SLR is about 50% worse than the D90. Of 4.5 for the Rebel SLR T1i, and 3.3 for the Nikon D90 DX.

Having extra pixels on an image sensor can cause several problems. How do you go in search of additional lenses, you will quickly learn that more megapixels means more expensive lenses fall. The better developed the lens with high resolution, the ability to come with an extra megapixel job, not the cheap lenses.

Hat box, the Canon EF-S 18-55mm hasf/3.5-5.6 IS with the EOS Rebel T1i, and it would not promise my favorite lens for a digital camera, 15.1 megapixels. In this writers humble opinion, a better lens for the Rebel SLR T1i should have been slightly more expensive 18-200mm Canon EF-S.

But that's not how far we are not ready to explain the difficulties with excessive pixel density. Pixel density can adversely affect the dynamic range, ISO, and diffraction. I do not know how about you, but I thinkthat getting a bunch fewer megapixels from the Nikon D90 12.3MP for more a few more bucks, may be a better choice for my dollar.

An camera industry accepted test used to evaluate RAW sensor data is the Dx O Mark test. DxOMark testing is not currently available, but the EOS Rebel T1i uses the Canon EOS 50D sensor. The testing has shown, that the D90 SLR image sensor is superior to the EOS 50D sensor. There's every reason to believe that forthcoming Rebel T1i test results will be very similar to the Canon 50D data.

2008 DSLR Review - The Hits and Misses of the Year

2008 was an interesting year for DSLR photographers and, in general, even if you ignore the ultra-high-end announcements from Leica, and Red Hassleblad The three main players in the DSLR space (with Nikon and Canon are about 40 % market share and Sony with around 10%) all started milestone cameras. Below we present in detail their hits and misses. Nikon After their pioneering publications in 2007 with the Nikon D3 and D300, they set the bar high for the year 2008, but ingenerally not disappoint with four new committees: Nikon D60 Although not revolutionary, the Nikon D60 replaces the D40x in Nikon's consumer lineup, into a smaller, better package to one of the smallest and lightest DSLR's ever made. Nikon D700 Coming almost a complete surprise, the Nikon D700 was launched in mid-summer, with the 12-megapixel full-frame sensor from the flagship D3, but with a body like the D300. At $ 3000, showed the cameraNikon's commitment to FX, and the camera is now the choice

The Digital Rebel T1i Faces the Competition

Not that it makes a difference as much as you can imagine, but the D90 Digital SLR has a tiny (12.3MP) image sensor as an affordable T1i Rebel (15.1MP). With these data and applying a little common sense would not lead to a technical person to believe that the Digital Rebel is by far the smarter buy T1i. As with many other things in this world and digital SLR cameras, things are not always as obvious as they should be. The image sensor from Canon is currently used,is not optimal sensor. Not, however, are starting to think everything you read digital SLR package. The APS-C sensor in the Rebel SLR T1i be used, will be rigorously tested to treat 15.1 MP in the best case. To achieve a higher megapixel rate, selected Canon are closer to the pixels, and smaller pixels than the Nikon D90 using 12.3MP used. It is the most widespread, fit more pixels to be on a smaller area. A more accurate indicator of imageQuality as a mega-pixel is pixel density. In this case, is the Nikon D90 12.3MP l

Is the Rebel T1i the Smarter Choice?

If your someone who is interested in technical data as you see it, the Canon Rebel SLR T1i has a 15.1MP image sensor, and the more expensive Nikon D90 has a 12.3mega-pixel image sensor. If these specifications have you needed, then it would be reasonably obvious that the T1i Rebel SLR is the best digital camera for the money today. The fact that only in the light of the numbers, you do not understand the big picture here. Bigger is often notbetter. Megapixels is often a large part of the sales of digital cameras, Fuji, Nikon and other manufacturers know that only too well. As for the Rebel SLR T1i, the merchandising department seems to be the design team have invented. The APS-C size image sensor T1i SLR employed, is a tiny hair used as the DX image sensor of the Nikon D90. Obviously, there are a couple of approaches to squeeze extra pixels in a smaller sensor. With tinier pixels, cotton, and they are closer togetherwork. A more accurate indicator of the photo quality than megapix
