The Canon EOS Rebel XTi / 400D scores a 33/100 in our evaluation, which was announced on August 24, 2006. This DSLR camera measures 127 x 94 x 65mm and weighs 556g (1.23lbs). Launched at a price of $520, its specifications may seem outdated compared to modern cameras.

For anyone confused by Canon camera names, fear not! The Canon EOS Rebel Tti is the American product name. It is called the 40D in Europe, and the Kiss Digital X in Japan. Throughout this article, we’ll mainly refer to it by the American name (Tti).

Despite being released in 2006, the Rebel XTi still offers decent performance for its price. However, today’s market provides more advanced options for both amateurs and professionals. This camera serves as a reminder of how far DSLR technology has progressed over the years.

Canon EOS Rebel XTi Overview and Optics

The optics of the Canon EOS Rebel XTi receive a score of 41 out of 100. This camera features a 10.1-megapixel CMOS sensor, a Digic II processor, and a shooting speed of 3 frames per second. Its DXOMARK sensor score is 62, and it has an APS-C sensor size. The Canon EF-S lens mount allows for a wide range of lens options, but this model does not include image stabilization. The aspect ratio is 3:2.

When compared to current market offerings, the Rebel XTi’s optics may not be as competitive. The 10.1-megapixel sensor and 3 fps shooting speed are below current standards, and the lack of image stabilization could be a drawback for some photographers. However, the camera still has value for those looking for an affordable option with the flexibility of the Canon EF-S lens mount.

The Canon EOS Rebel XTi’s optics may not be the most advanced, but they offer reliable performance and compatibility with a variety of lenses. This camera remains a viable choice for budget-conscious photographers seeking a simple and functional DSLR.

Canon EOS Rebel XTi Storage and Battery

The Canon EOS Rebel XTi receives a storage and battery score of 21/100. This camera has a single memory card slot, which accepts Compact Flash (Type I or II) cards. In comparison to modern cameras that offer multiple memory card slots and support for SD cards, the storage capacity for the Rebel XTi may seem limited.

Regarding battery life, the Rebel XTi / 400D offers 370 shots per charge, using the NB-2LH battery. This battery life falls short compared to more recent cameras that provide longer-lasting batteries and USB charging capabilities. The lack of USB charging in the Rebel XTi / 400D may also be considered a disadvantage for users who value convenience and portability.

Taking into account the storage and battery specifications, the Canon EOS Rebel XTi / 400D falls behind in today’s competitive camera market. The limited storage options and shorter battery life may deter potential buyers seeking more advanced features and capabilities.
