Canon EOS 700D/REBEL T5i/Kiss X7i review: New ‘EOS for Beginners’ flagship DSLR offers no improvement in sensor scoresBy Paul Carroll - Thursday May 02 2013 Sensor Review
EOS 700D vs. EOS 650D: No significant improvement over its predecessor
We can say the 700D has the same image quality as its predecessor. Portrait and Landscape scores are identical, and there’s a minor drop off for Sports, which just gives the EOS 650D the edge overall, scoring 62 points compared to 61. There’s no difference between the two models in real world terms therefore, and our measurement shows they effectively have same sensor.
This lack of improvement in Canon sensor scores is highlighted when looking back at the evolution of DxOMark sensor scores for Canon, Nikon and Sony entry-level DSLRs. Whilst a clear upward trend is evident for most new models from Nikon & Sony, Canon shows no significant improvement from the Canon 300D launched back in 2003 to this latest model.
Canon EOS 700D vs. Sony SLT Alpha 58 vs. Nikon D5200: Canon sensor scores off the pace of its main competitors
Pitted head to head against some of the latest entry-level competition therefore, the EOS 700D is somewhat off the pace. With a DxOMark score of 74 the $598 Sony Alpha 58 offers nearly a +1 Stop improvement in overall image quality, while the $879 Nikon D5200 is +1.6 Stops better overall with 84 points, a whopping 23 points more than the EOS 700D.
The starkest difference between the EOS 700D and D5200 is the Landscape Score, where at base ISO the Nikon model offers a +2.6 Stops improvement for Dynamic Range. Results for the D5200 do drop off more steeply compared to the 700D however, so by ISO 800 the Nikon’s advantage is down to +1.5 Stops, but the D5200 does offer better dynamic range at all ISO sensitivities. The same trend doesn’t occur with the Portrait scores however, where the Nikon D5200 offers around +1.5 Stops better Color Depth consistently through the ISO range compared to the EOS 700D.
The Sony Alpha 58 sits roughly in the middle and for Dynamic Range offers a +1.3 Stop advantage over the EOS 700D at base ISO, but from ISO 800 onwards they’re effectively the same. For Color Depth the Sony DSLR starts ahead of the Canon with 23.3 bits vs. 21.7 bits, an improvement of +1.6 Stops, but the gap narrows as sensitivity is increased and by ISO 3200 the Canon and Sony have the same Color Sensitivity.
For Low-Light ISO the EOS 700D and Alpha 58 are similar, scoring 681 ISO against 753 ISO respectively, but the D5200 takes the spoils again, offering +1 Stop better Low-Light performance with a score of 1284 ISO. Looking at the progression of ISO performance for entry-level DSLR releases, Nikon’s development over 10 years has seen a +0.5 Stop improvement in Low-Light and Sony have also made strides forward despite the switch to SLT technology, but Canon APS-C sensors haven’t developed to the same extent.
