Canon EOS 70D vs Nikon D7100: 15 things you really need to know

Canon EOS 70D vs Nikon D7100: 15 things you really need to know

Canon EOS 70D vs Nikon D7100 Comparison: 02 SENSOR

Canon EOS 70D vs Nikon D7100 Comparison: 02 SENSOR

The Canon EOS 70D has new 20.2-megapixel CMOS sensor measuring 22.5 x 15.0mm with a built-in/fixed low pass filter. The Nikon D7100 has a very slightly larger 24.1-megapixel sensor measuring 23.5 x 15.6mm with no low-pass filter.

Removing the filter means increased sharpness with fine details, though at the risk of moire effects with some subjects and patterns – though this does not seem to be a problem for the D7100 in practice.

It remains to be seen how well the Canon EOS 70D’s sensor performs in tests, but test results from the Nikon D7100 and the difference in specifications suggest that the Nikon should in theory yield slightly sharper images.

The slight difference in the sensor size also explains why the Canon has a 1.6x focal factor while the Nikon’s is 1.5x.

Canon EOS 70D vs Nikon D7100 Comparison: 03 EXPOSURE

The Canon EOS 70D has dual-layer 63-zone IFCL (Intelligent Focus, Colour & Luminance) exposure sensor. The dual-layer design makes it colour-sensitive, and is designed to eliminate random exposure errors caused by subject colours and light sources.

The Nikon D7100 metering system, meanwhile, uses a 2016-pixel RGB sensor. It’s not yet clear whether either one has an advantage in a Canon EOS 70D vs Nikon D7100 comparison, and the limitations of in-camera metering sensors in general and the different metering techniques of individual photographers mean that comparisons aren’t always meaningful.

Both cameras offer multi-pattern, centre-weighted and spot metering modes, but the Canon EOS 70D adds ‘Partial’ metering (a kind of ‘big’ spot mode).

    We intend to review both products head-to-head… but the Canon 70D isn’t released yet. As we stated in the article, we will be able to elaborate more on some points once we’ve had the camera in for testing.
