The EOS 90D is an update of the 80D, and the best and last of Canon's XXD line. Operation and appearance are nearly identical to the 80D, but with significant internal updates: 32.5MP Dual Pixel CMOS, vastly improved LiveView AF, Bluetooth, and full frame 4K video recording.

Construction

The 90D features a polycarbonate body shell, matte black paint, magnesium alloy undercarriage and seals on switches and ports. Like the 80D, the 90D sports a deep finger groove and rubber leatherette, making for a secure grip. In hand the 90D reveals heft and feels sturdy—no body flex or grip squeaks while shooting with heavier lenses like an EF 300 4L USM or EF 70-200 4L IS USM.

Touchscreen

The 90D uses the same articulating 3.0" 1,040,000 dot touchscreen LCD as the 80D. It's vivid and touch sensitivity is excellent and adjustable. Most button functions are duplicated on the touchscreen (albeit, I'd love a few more buttons). Plus, focus-pulls are a snap with the touch screen. While 80D image reviews appear almost instantly, 90D review is slow in comparison, taking nearly two seconds—the toll for having a 32.5 MP CMOS.

Optical Viewfinder

Canon designed the 90D and mirrorless EOS M6 MK II to share components and, thus, have many identical features and specs. You could shun the 90D optical viewfinder (OVF) and simply use LiveView features, and performance would be on par with its mirrorless sibling. Nevertheless, one of the main reasons I choose the 90D over the M6 MKII was for the OVF. I prefer the natural realism of an OVF. However, OVF beats EVF with higher dynamic range, real time viewing and great battery life. Current EVF designs are still prone to blocked up shadows and are dim in Hawaii's tropical sun. With that said, I own an EOS M6 and Olympus Pen—both with EVF—so I grin 'n bear it if I have to!

The 90D's glass pentaprism based viewfinder is a pleasure to use indoors and outdoors: bright, vivid and smoothly textured. The 100% coverage and .95x magnification are the same as the 80D but a marked improvement over Rebel (Kiss) viewfinders.

When the battery is removed, the viewfinder displays a dim and blurry image. The LCD overlay must be powered for full viewfinder brightness. Canon doesn't describe the Intelligent Viewfinder as a hybrid optical-LCD viewfinder but it is: speed and natural dynamic range of an optical viewfinder combined with the data display of an EVF.

Transmissive LCD Display

The transmissive LCD display—transparent LCD over the focusing screen—displays icons, AF and metering patterns, aspect ratios (3:2, 4:3, 16:9 and 1:1), grid and plain matte screens and an electronic level. When an aspect ratio other than 3:2 is selected, black borders are superimposed in the viewfinder. Crop lines are merely a compositional guide since the RAW file is full frame and may be cropped differently or not at all during post production.

The outermost lines of the grid overlay correspond to the 4:3 aspect ratio, so you could leave the grid superimposed if the thick black lines are distracting.

Controls

Buttons and wheels are similar to those on the 80D: sturdy and well placed. However, the shutter button was given a minor upgrade: feels more beefy and has a slightly longer throw than the 80D button. The shutter sound is subdued for a DSLR—muted but fast "klack"—and quieter than the 80D and 6D MK II. Silent drive mode fades sound to pianissimo, ideal for stage and ceremonies. If you desire completely silent operation, electronic shutter in LiveView is available.

The 90D boasts a significant control upgrade: a second multi-controller. It's within easy reach of the thumb and may be used while looking through the viewfinder. I programmed mine to move AF points. My 7D and 5D MKII had a joystick style multi-controller in the same spot, but the 90D 8-way multi-controller—shaped like a textured pad—is more responsive and easier to use. Oddly, the two multi-controllers mirror one another's operation. I wish they could be programmed for separate functions.

Exposure Modes

Like prior XXD series DSLRs, exposure modes are set with a knurled dial on the top deck: Creative Zone with manual and semi-auto modes—Program (P), Aperture Priority (Av), Shutter Priority (Tv) and Manual (M—and Basic Zone with assorted Full Auto modes. Creative Filters mode is new on the dial and offers silly options such as soft focus and grainy black and white. Two Custom (C) modes are included to save your favorite drive, exposure and image quality settings.

Metering patterns—Evaluative, center weighted, partial and spot—have a dedicated button on the top deck or may be set via the Quick Control screen.

Metering Icons | Evaluative, Spot, Partial and Center Weighted icons are used in the menus and Q-Screen to symbolize metering options.

FEC and White Balance

The 90D lacks dedicated flash exposure compensation (FEC) and white balance (WB) buttons. These functions are on the Q-screen but dropping camera from eye to use the screen may cost you a shot. I can live without a WB button, but I ride FEC when using flash and prefer use by feel controls. Button functions can be customized so I assigned FEC to the SET button, allowing FEC input while turning the rear dial and looking through the viewfinder. Well sort of. Unlike the 80D, the FEC scale on the 90D does not appear in the viewfinder, but on the rear LCD!

Tab Menu

The Tab Menu is the interface for changing camera features such as AF, video, button and dial customization, etc. To access the Tab Menu, press the MENU button on the back of the camera. Once activated on the LCD, you'll find six icon tabs grouped by category. Each icon category is color coded (red, blue, etc.) and has one to six numbered menus. Numbered menus may have up to seven sub-menus. Menus may be navigated by touchscreen or via wheels and buttons.

Unlike the prior 70D/80D, many settings for video and stills are separate and not available outside of the mode. For example, wireless remote release is enabled in stills mode, it is not enabled in video mode and vice versa.

My Menu

The sheer number of items in the Tab Menu can be overwhelming, especially in the field when you need to quickly change something. Canon helps us simplify by allowing user selected menus to be grouped under the Star tab for quick access. These custom menus—called MY MENU in Canon speak—will vary according to your taste and shooting style. I have three numbered menus of favorite settings but you can have more, less or choose not to use My MENU.

Auto Focus

The 45-point cross-type phase-detect AF system boasts a couple tweaks but is basically the same as the 80D. The main upgrade is it can now focus with certain F8 lenses using 27 points. Thus, a F5.6 telephoto with 1.4X Extender can now use auto focus. Also new is the ability to use iTR AF face priority detection while shooting through the optical viewfinder.

iTR stands for Intelligent Tracking and Recognition. Face detection technology is somewhat rare on DSLRs but common on mirrorless cameras. The 220,000 pixel auto exposure (AE) RGB sensor guides tracking of faces with the optical viewfinder in 45-point and zone modes. I found iTR AF locked onto faces lickety-split and rarely missed. It's a great mode for social events, especially if you've enjoyed a few too many cold ones during the shoot. Selfie shooters will now have razor sharp eyeballs to sprinkle all over social media.

EOS iTR AF face priority detection can be disabled in the menus if desired.

Focus Modes

The 90D has all the AF modes of the 80D—single-point AF, zone AF, large zone AF and 45-point automatic selection AF—plus single-point AF with reduced size, i.e., spot focus. Spot focus is my favorite AF mode for macro as it allows a precise lock on a tiny point of contrast. For general shooting, I mainly use zone AF and move it around as needed with the multi-controller.

LiveView AF

LiveView AF has similar modes as the viewfinder and then some. The big deal is the 5481 point AF in LiveView with 88% horizontal and nearly 100% vertical sensor coverage. Do I ever need to focus on the edge of the frame? Nope, but it's there when you need it. And you can use the shutter button or poke the screen with your finger like an iPhone!

Eye AF—standard on EOS R series and recent M series mirrorless cameras—is a new 90D AF mode where the camera detects a human face and subsequently locks focus on an eye. It works great at close range even in subdued interior lighting.

LiveView has a few more tricks up its sleeve. For example, tap the subject on the touchscreen, half-press the shutter button and the camera tracks the subject across the screen using AI Servo.

As much as I like LiveView, I mainly use it on a tripod in single point mode for macro and studio shots. Holding a DSLR at arm's length in the tropical sun isn't practical or steady.

AF Microadjustment

Like the 70D and 80D, the 90D allows AF Microadjustment (AFMA): individual lenses may be calibrated for optimal sharpness. Zoom lenses may have two calibrations: one for the wide end of the range and another for the long side. For example, my EF-s 18-135 3.5-5.6 IS USM needed +7 at 18mm and +5 at 135mm to be critically sharp. My EF 70-300 4.0-5.6 IS USM is perfect at AFMA default (0). Settings are stored in camera memory and used each time the lens focuses with the 45-point array. Using the Dot Tune method, it took me about 15 minutes to calibrate each lens.

Dual Pixel AF (on-chip contrast focus) doesn't need calibration. Thus, images taken with Dual Pixel AF are an excellent base of comparison while calibrating lenses for the 45-point array.

AutoISO

The AutoISO feature sets ISO according to changing lighting conditions, maintaining a reasonable shutter speed for hand held photography. The 90D sports the latest and greatest AutoISO iteration: works in manual (M) mode and is programmable. In M mode, set desired shutter speed/F-stop and ISO scales up and down with changing light, maintaining proper exposure. Thus, M mode becomes a semi-automatic mode. Exposure compensation (EC) works in M mode with AutoISO and may be set on the Q-Screen.

At default, AutoISO is set to favor shutter speeds near the one/focal length ratio. The default is too slow for me but AutoISO can be programmed to control minimum shutter speed: in the ISO speed settings menu adjust default shutter speed to faster or slower than the default. I programmed my 90D's AutoISO 1-stop over default.

As good as AutoISO is, there are situations where manual setting of ISO yields a better result. I set ISO manually when using flash, shooting in studio lighting or using a tripod for long exposures.

Flash

The popup deploys at the touch of a button or, in Intelligent Auto Mode, auto erects. It may also serve as master/trigger for wireless slave capable Canon Speedlites. Popup flash range is limited but works fine for close snapshots or fill-in. Flash images were well-exposed using the popup and 430EX MKII.

The main gotcha with AutoISO is flash: defaults to ISO 400 no matter what mode used or light level. When using fill flash in bright light, the background blows out due to the combination of low maximum sync speed (1/250 sec.) and high ISO. My solution is to manually set ISO 100, resulting in a stop or so of exposure leeway. In low light I prefer slow sync to blend ambient light with fill, and ISO 400 is often too slow, resulting in blurring. I dial in ISO 800 or 1600 for a sharp background and fill flash makes the subject pop.

Image Quality

No scientific measurements but my observation is 90D image quality is slightly improved over the 24MP CMOS in the 80D. RAW images converted in DPP reveal pleasing detail, color rendition and noise control. However, in most shooting situations, these improvements are not something I'd notice beyond the increased resolution. And, yes, I crop more often now. Image improvement is most noticeable in low light where I can see a small reduction in noise compared to the 80D, especially at high ISO.

Video

The 90D is principally a still image camera. However, video is a well implemented feature, ideal for video bloggers and performance artists. Indeed, I only use the video features for my music performances and instructional videos. Canon Log and time code are not included, so if you're planning to take your video productions beyond YouTube and Facebook clips, the 90D isn't the camera for you.

ALL-I and IPB?

The 80D allows a choice between ALL-I and IPB, and a choice between MOV and MP4 output. The 90D only records IPB and MP4. Nevertheless, HD video with IPB compression is a little less noisy in low light and slightly more detailed than the 80D. Not an earth shattering difference but welcome. Thus, the ALL-I omission is irritating but not a deal-killer.

The 4K (24 or 30P) option is full frame width! You have the option of using cropped 4K, if you need extra reach. My old Mac Mini (7i 4-core CPU and 16 GB RAM) struggled with 4K video editing—overheating within minutes—and so I stuck with 1080P initially. After I upgraded to an iMac Pro (3.2 GHz 8-Core Intel Xeon W and 32GB RAM), I noticed little or no change in Final Cut Pro processing time compared to 1080P. Plus, downsizing 4K to 1080P looks really good—sharper than regular 1080P. Here's a sample of one of my 4K v-blog videos shot at the 30P frame rate. Camera settings were all manual: exposure, WB (4500K), ISO (640) and audio.

One thing about 4K video is it eats batteries faster than 1080P. I can shoot an entire concert on one battery at 1080P. With 4K, I need an extra battery or two.

Video Exposure Modes

There are three video exposure modes: Full Auto, Program and Manual. If you set Av, Tv, or B, the camera reverts to Program mode. Program mode sets aperture and shutter speed and but allows user input of AF mode, white balance, ISO and exposure compensation. Manual lets you choose the aperture and shutter speed. However, Manual mode also works with Auto ISO, achieving a quasi-auto exposure mode by changing ISO. Exposure compensation also works in Manual mode with Auto ISO enabled.

For YouTube work I use manual exposure and dial in ISO and white balance. Once adjusted for studio lighting, there are no worries about WB balance or exposure changing due to a backdrop or clothing change. It stays put.

Movie Servo

Dual Pixel movie servo AF is noticeably improved over the 80D: more accurate tracking, faster and less prone to hunting in low light. You can focus on your subject by using the shutter button, AF-on button or touching the screen with your finger. Even more impressive, you can drag your finger across the LCD and it smoothly pulls focus from near and far objects! And, of course, Movie Servo AF, like LiveView, includes Face Detect + Tracking and Eye Detect AF options.

With all that said, I prefer to keep it simple and use area focus with movie servo for my YouTube videos. Of course, I'm just sitting on a chair playing guitar or 'ukulele.

White Balance

Auto white balance (WB) nails color temperature most of the time, even in mixed lighting. Like most EOS cameras I've owned, the 90D leans towards the warm side. The one situation Auto WB fails are scenes filled with lots of pinks and reds, resulting in a 1000 degree jump to the warm side. However, I avoid "surprise" WB by setting it manually for studio video and photo sessions. Unlike the Rebel series, the 90D uses a scale marked in kelvin (K) for ease of setting.

Clean HDMI Output

The 90D is the first XXD series camera with clean HDMI output for recording to an external video recorder. When this option is selected, recording to the camera memory card is disabled.

Audio

Built-in audio is essentially the same as the 80D: manual or automatic levels, omnidirectional stereo mics and a stereo mini jack for monitoring. Audio is okay for casual clips but the mics and preamps are too noisy for serious music productions. I use built-in audio as a guide track for outboard audio, preferring Tascam recorders and external mics for music videos.

However, if you use the onboard preamps, use manual audio levels for best results. Auto levels surge gain up and down, increasing hiss greatly during quiet passages. Set your external mic to the highest output gain—+10 or 20 dB—thus allowing lower levels on the camera and, subsequently, less preamp noise.

Connectivity

The 90D builds on the Wi-Fi connectivity features of the 80D by adding Bluetooth. With Wi-Fi enabled and the Canon Camera Connect app, you can diddle settings, fire shutter, zoom the Power Zoom Adapter PZ-E1, upload images and use LiveView on an iPhone/iPad, Droid or computer. It works well on both my iPhone and iPad (didn't try an iMac). Video may be monitored through Wi-Fi. Bluetooth is used to connect with accessories such as the Canon Wireless Remote Control BR-E1 and to "help" Wi-Fi connectivity.

Connecting with Wi-Fi to an iOS device is fiddly the first time but easy once setup, especially coupled with Bluetooth as an helper. With that said, I rarely use Wi-Fi. Why? When I get home, I upload to my iMac with a Lexar Pro USB 3 card reader: blazes compared to Wi-Fi and allows multiple cards uploads.

As a solo YouTube artist, I self-shoot most of my videos. Thus, use of the RC-6 Wireless Remote Controller or Canon Wireless Remote Control BR-E1 to start and stop video recording is a huge plus. Plus, these devices are small and easy to use compared to holding a guitar and iPhone.

Battery Life

The 90D uses the same battery type as the 70D, 80D, 5D MKII, 6D, R, etc., the LP-E6 series. The difference is the 90D shipped with a slightly stronger variant, the LP-E6N, but is compatible with the LP-E6 variants and new LP-E6NH. Shooting RAW with the kit lens, I easily get 1400+ images and still have a partial charge left, so 90D battery life is excellent. Of course, this is with Wi-Fi disabled, no live view and only minor chimping. As for video, I can shoot through an entire student recital on a single charge, over an hour of HD video clips, and still have juice to spare. Take a space battery or two if shooting 4K.

Arca Compatible Plates

Promedia, Kirk and RRS currently make dedicated Arca compatible plates for the 90D. Sunwayfoto makes an L-bracket. Sadly, the RRS 70D and 80D body plates I already have don't fit the 90D. Luckily, an old Promedia 60D body plate I tossed in a drawer a decade ago fits perfectly. It uses a pin to prevent twist (the tiny hole to lock the battery grip). It's less expensive and bulky than the newer Promedia, Kirk and RRS designs and I'm happy using the Promedia for tripod duty.

Musings

The 90D is a highly competent design, quick on the draw and a significant upgrade over the 80D in terms of LiveView and video AF, still and video resolution, and noise control. For all intents and purposes, it a merging of Canon DSLR and mirrorless designs. Through the optical viewfinder it's a highly capable XXD series DSLR. In LiveView and video modes it's essentially an EOS M6 MKII. Amazingly, it's the first EOS DSLR in this price range without crippled 4K video—i.e., full use of Dual Pixel AF and no cropping. Even the mirrorless EOS RP lacks Dual Pixel AF in 4K mode and suffers a 1.72X crop in 4K. For a generalist shooter like me, the 90D strikes a nice balance of performance and cost. Without doubt this is the best XXD camera design ever and, sadly, the last of its kind. The thoughtful design and improvements add up to an enjoyable experience and excellent images.

The 90D is a great choice for video bloggers and YouTubers due to the eye and face priority movie servo and reversible LCD screen. However, if LiveView and video are your main mode of usage, you probably should consider an EOS R7, R10 or EOS R6 MK II instead of the 90D.

Better Late Than Never

I bought the 90D late in 2019 and normally write a review after about three months of shooting. Unfortunately, the COVID-19 lock-down hit and my travel plans and photo shoots were put on hold for much of 2020. Converting my college music courses to online format ate most of my spare time, albeit I got use the video features of this camera extensively. So this review is a year late...
