There isn’t really any direct competition with the Canon EOS 7D. Nikon’s top-end APS-C-format DSLR, the D300s, has a considerably lower resolution of 12.3 million effective pixels. It also has a street price of around £1,250, almost £450 less than the current street price of the EOS 7D.
Meanwhile, the 14.6-million-pixel Pentax K-7 retails for around £1,000. Although the Nikon D300s and Pentax K-7 are both impressive for their pixel count, neither can quite match the detail resolution of the EOS 7D.
It also trumps both of their maximum sensitivity expansion settings of ISO 6400. Without a head-to-head shoot-out it is difficult to say whether the Canon or the Nikon AF system is faster, but both beat the Pentax K-7. However, on paper at least, the Nikon 300s would appear to offer the slightly better deal with a detection range of -1-19EV instead of -0.5-18EV and a total of 51 AF points rather than 19.
The EOS 7D does, however, have more cross-type AF points than the D300s, as all 19 are biaxial rather than just 15 in the Nikon camera. Either model would meet the needs of the sports enthusiast, but some may be put off by the comparatively high cost of the EOS 7D.
