Canon EOS 90D Review

Canon EOS 90D Image Quality

All of the sample images in this review were taken using the 32 megapixel Fine JPEG setting, which gives an average image size of around 8Mb.

The new high-resolution sensor of the Canon EOS 90D is great news for those who want to get the most detail possible from their shots. If you’re somebody who likes to shoot macro images, for example, you’ll be able to reproduce more detail than was available before from a Canon APS-C DSLR.

That said, having so many pixels without inbuilt image stabilisation in the body can mean you need to be a little bit careful with how you keep your images as sharp as possible. To that end, keeping shutter speeds as quick as possible, while a tripod for close-up work is a good idea.

JPEGs directly from the Canon 90D are very pleasing, with excellent vibrant colours which are just the right side of realistic. On the whole, automatic white balance does a good job of keeping colours in check in a variety of lighting conditions, while the all-purpose (evaluative) metering works well to produce balanced exposures.

As Canon’s metering system weights exposure towards the active AF point, you might find in certain high-contrast situations, you need to switch to spot metering for best results, but for most everyday situations it’s a great performer.

When it comes to high ISO performance in low light situations, if you can keep the ISO setting to ISO 6400 and below you’ll find you have the best quality images. ISO 12800 is usable at smaller sizes, but a loss of detail and image noise is apparent at A4.

Noise

ISO sensitivity can be set between ISO 100 and ISO 25600 in full-stop increments, and a boosted setting of ISO 51200 is also available. Here are some 100% crops which show the noise levels for each ISO setting, with JPEG on the left and the RAW equivalent on the right.

Flash

The flash settings on the Canon EOS 90D are Auto, Manual Flash On/Off, and Red-Eye Reduction. These shots of a white coloured wall were taken at a distance of 1m.

Flash On - Wide Angle

And here are a couple of portrait shots. As you can see, neither the Flash On setting nor the Red-Eye Reduction option caused any amount of red-eye.

Long Exposures

The Canon EOS 90D's maximum shutter speed is 30 seconds and there's a Bulb mode for even longer exposures, which is excellent news if you're seriously interested in night photography. The shot below was taken using a shutter speed of 30 seconds at ISO 100.
