Canon EOS 750D Review – Image Quality: Detail and Noise
The 760D produces an identical level of detail to the 750D and at its base sensitivity setting the 24-million-pixel sensor resolves 3200l/ph. Users can expect the resolution to drop gradually as the sensitivity is increased, but a close inspection of our resolution chart revealed 3000l/ph are resolved up to ISO 800. The sensor preserves 2800/lph up to ISO 3200, but from this point onwards detail deteriorates more rapidly as the sensitivity is increased to about 2600l/ph at ISO 6400, reducing to 2400l/ph at ISO 12,800. The 760D’s sensor struggles to resolve more than 2200l/ph at ISO 25,600.
Noise
Clean, noise-free images are produced between ISO 100-400 and it’s only when you move up to ISO 800 that the first traces of luminance noise become apparent. Noise at ISO 800 is by no means offensive and the noise reduction that’s automatically applied by the camera to its JPEG files doesn’t have an obvious impact on the level of detail that’s captured until you reach ISO 3200. Beyond ISO 3200 there’s an increasing level of noise introduced into JPEG and Raw files. ISO 6400 is useable provided some noise reduction is applied in post and images aren’t printed too large. Pushing up to ISO 12,800 and 25,600 introduces chroma noise, which is most noticeable in the images shot at the 760D’s ISO ceiling.
