If you are a photographer who captures any high speed action (wildlife or sports) and are a die-hard Canon fan, you were probably stuck with choosing between the flagship APSC EOS 7Dmkii and the flagship full-frame EOS 1Dxii/iii. Both of these cameras are equiped with superior autofocusing systems as well as fast buffers and are able to capture at least 10fps. The thing is, the former is full of old technology (released 2014) and poor low light performance, the latter, costs a bomb and probably not suited for the hobbyist or struggling student. It was a really, really long wait, but finally, the EOS 90D fills in that gap.

My primary DSLRs are the 7Dmkii and 80D, both of them have their pros and cons, which is why I use them separately for wildlife and macro photography respectively. This time round, Canon merged the best features (mostly) of the two into one sleek DSLR body.

Detailed technical specifications of the camera are beyond the scope of this article (there are tons of review sites who will do that for you), but instead I will show you some sample images and share some thoughts about the camera from a user’s perspective.

The 90D is a semi-professional camera and as the successor of the popular 80D, you can expect improvements. Coming in 30g lighter and just a tad thinner than the 80D, you probably won’t feel a significant difference but what’s new this time is the aluminum alloy and polycarbonate resin with glass fiber used to craft the camera body. Basically the same touch and feel as the new R bodies.

Skipping past a few minor tweaks (button rearrangement and mode dial), the biggest improvement comes from the inclusion of the joystick. Generally found in the more professional bodies like the 7Dii and the 5Dmkiv, the 8-direction joystick control makes handling such as quick selection of autofocus points much easier. A definite plus for wildlife shooters. Unfortunately the joystick and multi-controller are not customisable and serve the exact same functions.

The 90D is the highest resolution APS-C DSLR to date boasting 32.5MP and supported by the DIGIC 8 image processor. As a comparison, its predecessor (the 80D) has a 24MP sensor powered by the DIGIC 6 image processor. If cropping your images are essential (as majority of wildlife and macro shooters require), this camera gives you enough pixel density to maintain sharp, detailed images post-crop.

That being said, with 32.5 million pixels crammed into a cropped-sensor, you can expect a certain amount of noise in your images at certain ISO settings as compared with sensors with larger pixels.

The 90D has the same 45 cross-type autofocus (AF) points as the 80D, albeit the hopes of many for more AF points to cover a larger area in the optical view finder (OVF). However, Canon included its famed Dual Pixel CMOS AF system which allows over 5000 selectable AF points which provides almost full coverage across the sensor during live view shooting. Thus giving more compositional freedom.

Face detection also works when using the OVF, a feature that is hardly seen in DSLR cameras, no animal eye AF here of course.

Another exciting feature is the ability to shoot 10 frames per second (fps) despite the 32.5MP and the single DIGIC 8 processor. This places the 90D at the same level of the 7D mkii and faster than the 80D which shoots only 7fps. More fps would mean more chances to capture every bit of action you are seeing. However, the camera’s buffer capacity simply cannot keep up with the higher resolution images and speed at 10fps, so you can expect to take lesser images in a continuous burst as compared to both the 80D and 7Dmkii.

*Note that shooting with the Live View can grant you 11fps using AI focus (great for static subjects) but only 7fps when using AI servo.

What about the autofocus performance under low light? I tested the AF performance of the 90D during my usual macro shoots and the camera had no issue with focus breathing and acquired the subject quickly (single point spot AF + AI servo was used). This is despite the slow AF of the old 100mm L macro lens.

Needless to say, the optical view finders on DSLRs produce zero lag and what you see is what you get. So I switched up the camera to live view and noticed minimal lag and accurate metering on the screen. Having an articulating screen is a must have for macro work when the need to shoot at unconventional angles arises. Some older cameras like the 7Dii have rather dimmed screens when shooting in live view which is horrible especially when you can’t even see if your subject is in focus or not.

Lets talk image quality. The CR3 RAW files that the 90D produces is the best I’ve seen in the entire APSC line up (the sensor is similar to the one found in the new EOS M6 mk ii). The dynamic range of the 90D has definitely seen a large improvement over its predecessor. I found myself being able to extract more detail in the blown out highlights and underexposed shadows on some images, making them usable again. When I took the shot above, I never had the intention of exposing the web surrounding the stabilimenta (that intricate decorative web the spider was on) and it was originally underexposed and dark. Regardless, I managed to extract all that detail with minimal colour noise and banding.

If you shoot JPEGs, you can expect really pleasing colours as the camera does the compressions, sharpening and slight colour adjustments for you. However, some fine detail may be lost due to the noise reduction rendered on the JPEG, not an issue if you don’t do large prints.

Another example of how simple it is to extract detail out of subjects that are darker. Image was stacked to obtain a larger depth-of-field.

Similar to the EOS RP, the 90D comes with the new focus-bracketing feature to help you focus stack. The experience using this feature is identical to the RP and my thoughts about this feature still remains. I would not recommend using it as it is too much of a hassle to set up a tripod and your subject has to be completely compliant. Doing this in the field would result in tons of lost images. Handheld stacking would be more effective and efficient. Moreover, the feature will only work with lenses that have autofocus.

Battery life is just as what you would expect from a Canon DSLR. You pretty much can shoot all day on a single charge. In terms of power management given all the new technology, the 90D can actually sustain more shots on a single charge compared to both the 80D and the 7Dmkii.

There really isn’t much to dislike about the camera considering the 90D is in fact a large upgrade from the 80D. From amateurs to semi-professionals who are looking for a versatile, powerful all-rounder body that can utilise both EF and EF-S lenses, this is the camera for you. I have not even touched on all the other pro-grade features and the video capabilities that the camera provides. At its price point, it brings much value to the table.

In conclusion, the 90D is a camera for enthusiasts who are still not ready to embrace the mirrorless revolution and one that can get the job in almost any situation. I’m impressed with everything the camera can acheive but it would have been more of a hit if it was released 2-3 years ago. The EOS 7Dii still reigns as the flagship in the APSC lineup but with the new technology and features the 90D provides, I would definitely choose the 90D.
