To evaluate the multi-frame noise reduction capabilities of the Canon EOS T4i / 650D, I shot this scene first of all in Aperture Priority, then again in Multi-frame NR mode at each sensitivity.

The Rebel T4i / EOS 650D was fitted with the EF-S 18-135 f3.5-5.6 IS STM kit lens.


The above shot was taken with the Canon Rebel T4i / EOS 650D with the EF-S 18-135 f3.5-5.6 IS STM kit lens. The camera was placed on a tripod. The default camera settings were used other than Auto Lighting Optimzer was disabled. Peripheral illumination correction was enabled, long exposure noise reduction was turned off and High ISO speed NR was set to Standard.

Canon has introduced a new feature on the Rebel T4i / EOS 650D called Multi shot noise reduction. This 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 T4i / 650D'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 400 ISO, though the lower ISO crops certainly don't look any worse than their single shot conterparts. From 400 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 Rebel T4i / EOS 650D sample images to see some more real-life shots in a variety of conditions.
