To evaluate the multi-frame noise reduction capabilities of the Canon EOS M, I shot this scene first of all in Aperture Priority, then again in Multi-frame NR mode at each sensitivity.

The EOS M was fitted with the EF-M 18-55mm f3.5-5.6 IS STM kit zoom set to its maximum wide angle, 18mm (29mm equivalent).

 


The image above was taken with the Canon EOS M.The camera was placed on a tripod and the stabilisation was disabled, but otherwise the default settings were used.

Canon introduced the new Multi Shot Noise Reduction feature on the Rebel T4i / EOS 650D and it's good news that they've chosen also to include it on the EOS M. It takes a fast sequence of four shots and combines them to produce a single low-noise image. The crucial thing with Multi Shot Noise Reduction is that, unlike Handheld NightScene, the EOS M's other low-light stacking mode, Multi shot noise reduction allows you to manually set the ISO sensitivity.

The crops below show Multi shot noise reduction at each ISO setting compared with the single-shot equivalent. As you might expect, you don't really begin to see any advantage from Multi Shot Noise Reduction until 800 ISO. At the lower sensitivity settings I'd definitely recommend you avoid it as it further softens detail in the EOS M's already soft JPEGs and there's really nothing to be gained from a composite at lower ISO sensitivities where the single shot quality is excellent. From 800 ISO upwards, though, there's a clear quality benefit, probably in the region of one to two stops, to be gained from using Multi shot noise reduction.

Now head over to my Canon EOS M sample images to see some more real-life shots in a variety of conditions.
