Camera test 37

With ISO speeds available now into the millions, the EOS 80D’s top native ISO of 16,000 is decidedly modest and if youwant a DSLRwith a cutting-edge top ISO Canon has other models in its range for you. The EOS 80D’s 16,000 top speed can be boosted slightly further to ISO 25,600 but that is only two thirds of an f/stop more. So super high ISO shooting is not on this camera’s agenda. That said, what’s available is very usable. This set of images taken using a tripod-mounted camera and the 18-135mm f/3.5-5.6 zoom was taken during twilight with the Kenro Travel Tripod 2 tested elsewhere in this issue. The base ISO 100 exposure was 5secs at f/8. All noise reduction was switched off for this test and the Raw files were processed in Lightroom with default settings so they can be easily improved further. Performance: ISO

Images are clean up to ISO 400 and that speed is fine for critical work although there is evidence of colour noise that some work in software should resolve. Noise levels then climb and even by ISO 800 it is evident in areas of mid-tone and shadows. The impact of fine detail looks minimal though despite the higher noise. Personally ISO 2000 is about the limit for me. It is quite coarse at this point but has a filmic feel. Beyond that images look coarse and the blotches of red and green colour noise are off-putting. In summary, the EOS 80D has a respectable ISO performance particularly at the lower settings up to 800 but this no more than you’d expect from a recently introduced DSLR. Once you start to ascend the speed scale, though, its showing is less impressive compared with the best around today.

The EOS 80D has four high ISO noise reduction settings: low, standard, strong andmulti-shot. In the latter setting, four pictures are taken in rapid succession and the resulting JPEGs are processed, so this process takes a few seconds. The setting is greyed out if any Raw save option is selected. Test shots were taken at ISO 1600, 3200, 6400 and 12,800 in each of the four high ISO NR settings. The images shown here are straight-of- the-camera JPEGs. The high level of colour noise of the no NR and lowNR shots show that if you are going to shoot JPEGs at this ISO normal or strong NR is advised even though the last named does have an impact on ultimate resolution. It is no surprise that the multi-shot (ms) NR gives the most impressive pictures with a good impact on noise levels without impacting greatly on detail rendition.
