Canon EOS 100D review – Noise, resolution and sensitivity
Image: These images show 72ppi (100% on a computer screen) sections of images of a resolution chart, captured using the Sigma 105mm f/2.8 Macro lens lens set to f/8 . We show the section of the resolution chart where the camera starts to fail to reproduce the lines separately. The higher the number visible in these images, the better the camera’s detail resolution is at the specified sensitivity setting.
With a variation on the 18-million-pixel sensor that has been used in a number of Canon EOS cameras, there was nothing too surprising about the images produced by the EOS 100D.
Generally, the sensor captures a good amount of detail, though as we’ve noted numerous times with Canon cameras, there can be quite a big difference between the detail that can be resolved in raw files and that which is present in JPEGs produced in-camera. A slight tweak to the local contrast and sharpening settings really brings out the finer details in images, which can otherwise be lost in JPEGs.
At the lowest sensitivity settings, the Canon EOS 100D is able to resolve up to around 28 on our chart. If you are shooting raw images there is a slight improvement, but it can’t resolve much higher. However, the lines are more defined, especially after a slight sharpening.
A hint of colour noise can be observed in the shadow areas in JPEG images taken at ISO 800, though this doesn’t really become a concern until about ISO 3200. I have said it before, but I find it odd that camera manufacturers don’t do more to remove colour noise altogether from in-camera JPEG images, given how easy it is to reduce it in raw files using post-processing software.
It is also at ISO 3200 that luminance noise starts to become noticeable, and it appears that luminance noise reduction also becomes stronger here, as there is a drop in detail resolution. I’d suggest that ISO 3200 is about as high as anyone would really want to shoot.
I took some shots in very low light at ISO 6400 and ISO 12,800 and there is a lot of luminance noise reduction applied to JPEG files. Colour noise is also visible in some areas in the form of slightly purple and green-looking blotches.
Overall, image quality is perfect for the fair-weather photographer. For those that like to shoot in low light, the Canon EOS 100D does seem to struggle at higher sensitivities, and time will have to be spent editing the raw files to get the best from the camera.
Image: Although the Canon EOS 100D resolves a fair amount of detail, raw images must be captured to really get the most from the camera
Image: Heavy noise reduction is applied to JPEGs. The difference is clear in this ISO 6400 image, with heavy smudging, a lack of detail and coloured green and purple bruising still visible. None of which is evident in the raw image
