Canon EOS M3 Review

Canon EOS M3 Review

The Canon EOS M3 is a compact and versatile mirrorless camera that delivers impressive image quality and advanced features. With its sleek design and powerful performance, it’s the perfect companion for capturing stunning photos and recording high-quality videos. Experience the perfect balance of portability and functionality with the Canon EOS M3.

In addition to single-lens reflex cameras (SLRs) and point-and-shoots, Canon has been selling mirrorless cameras since 2012, which is a fact that many people are unaware of. The entry-level EOS M10 and the step-up EOS M3, which will be discussed in this article, are being marketed more aggressively in the United States as part of Canon’s EOS M system, which offers two different models to select from.

Canon EOS M3 (Black Body Only) - International Version

Last update was on: May 29, 2023 5:27 am

The EOS M3 is like a Rebel T6s that has been compressed into a body smaller body and is more similar to the company’s PowerShot products.

It has a touchscreen LCD, Wi-Fi with NFC, and the same Hybrid CMOS AF III 24.2MP CMOS sensor found in the T6s. Additionally, it has a Digic 6 CPU. In contrast to EOS DSLRs in general and the Rebel in particular, EOS M bodies utilize the EF-M lens mount; however, EF lenses may be used with the help of an extra adapter.

It might be challenging to determine a place for the EOS M3 within the current landscape of mirrorless cameras. The Fujifilm X-A2, the Olympus E-M10 II, and the Sony a6000 may be considered its most direct competitors regarding price and features. Nikon 1 cameras have been omitted from the list since we think the series is no longer being produced.

The Fujifilm, much like the EOS M3, does not have an electronic viewfinder (EVF) integrated and instead featured an LCD that can be rotated upwards by 180 degrees. The Olympus E-M10 II and the Sony a6000 feature electronic viewfinders, but neither has a “selfie” LCD.

The EOS-M system

Canon only offers six different EF-M lenses, even though the system being around for more than four years. They consist of two prime lenses and four zoom lenses (11-22 F4-5.6, 15-45 F3.5-6.3, 18-55 F3.5-5.6, and 55-200 F4.5-63). (22mm F2 and 28mm F3.5 macro). Tamron and Samyang/Rokinon are only two examples of third-party manufacturers that produce lenses (which are the manual focus).

You may utilize an extra adapter, which costs around $80, to gain access to the whole array of Canon EF and EF-S lenses. This will allow you to choose the lens that best suits your needs. It turns out that there are adapters for virtually any lens mount imaginable, from Leica to Olympus OM. Some examples of these adapters are shown below.

Body & Controls

The Canon EOS M3 is a small mirrorless camera with a body that is ever-so-slightly rounded and a grip that is pleasantly curved. However, it is not pocketable. On the other hand, tOn the other hand, the magnesium alloy exterior and stainless steel chassis contributes to the camera’s reassuringly robust sense of build quality.

Although the dials and controls on the back are made of plastic and have a cheap feel, the mode, and exposure compensation dials are made of metal and blend in with the body.

The front grip and the rear thumb rest are superb, enabling one-handed photography (at least when using smaller lenses). Additionally, the central and exposure compensation dial is within reach without moving your hand.

However, to alter the exposure settings, you will need to switch the position of your hand to access the rear control dial. Because of this, you cannot make adjustments quickly. Another thing that annoys me about the camera is that the buttons for video and playback are flush with the camera’s body, so you can’t even tell when you push them.

Tilting LCD

The LCD of the M3 may be tilted, just like most mirrorless cameras on the market today, including the M3. For better selfies, it can also be flipped up to 180 degrees from its normal position, which tilts downward by around 45 degrees. The screen is 3 inches and is packed with 1.04 million dots. We observed that the visibility outside was far higher than usual.

The touchscreen interface of the Canon is both snappy and intuitive, even though it does not introduce any groundbreaking new features.

Tapping the screen allows you to focus or take a shot, just as you might think. You can navigate through the menus, swipe through the photographs, pinch-to-zoom, or double-tap to get a closer look at anything.

Optional EVF

Even though the M3 does not come with an integrated electronic viewfinder, Canon provides an optional accessory that can be attached to the camera’s hot shoe. The electronic viewfinder, or the EVF-DC1, features a conventional LCD with 2.36 million dots and can be tilted upward by around 90 degrees.

An eye sensor makes the transition between the LCD and the electronic viewfinder (EVF) automatically; nevertheless, there is a very slight delay. Take into consideration that the cost of this EVF will be around $200.


The Canon EOS M3 features seven programmable buttons and a menu that may be altered. The shutter release, both dials, the ‘down’ direction on the four-way controller, and the M-Fn, Movie, and AE lock (*) buttons are the controls whose functions may be changed. Other rules that can have their roles reassigned include the four-way controller.

A good number of settings are accessible for the other buttons, in contrast to the shutter release button, the dials, and the AE Lock button, which have fewer options.

In the primary Menu, there is a section labeled “My Menu” that is tinted green and in which you may save up to six of the menu items you use most frequently. After that, you will have the option of making the My Menu the default location that is accessed whenever the menu button is hit.

Auto ISO

The EOS M3 only has the most basic Auto ISO system available. You can set the highest possible ISO, and that’s all. You have no say in the shutter speed at which the camera adjusts the ISO; you can only put your faith in the camera’s judgment.

The one advantage of shooting in manual mode is that you can employ exposure compensation in conjunction with auto ISO. This allows the camera to automatically change the ISO setting while maintaining the aperture and shutter speed you selected.


We anticipated that the performance of the EOS M3 and the Rebel T6s would be comparable, given that both cameras employ the Hybrid CMOS AF III technology. This system consists of 49 phase-detect sites covering 80% of the horizontal frame and 70% of the vertical structure, respectively.

This is not the same as Canon’s Dual Pixel technology, found on their more expensive cameras, such as the EOS 7D II and 80D. First, before we tell you how well the camera worked, let’s take a quick look at the several available AF modes.

You can choose between One-Shot and Servo AF in the section labeled “AF operation.” These modes are analogous to Single AF and Continuous AF, respectively; from this point forward, we will refer to them as AF-S and AF-C, respectively. Face Detect + Tracking and 1-point AF are the two ‘AF techniques related to the AF area. Look Detect + Tracking is the default setting.

You may boost the speed at which the camera can focus by instructing it to continue even after removing your finger from the control button. This function, which Canon refers to as “Continuous AF” (not to be confused with the continuous “Servo AF” mode), reduces the amount of time that a battery can hold its charge.

The first test that we run demonstrates the capabilities of the camera when set to AF-C + 1-point mode. This would be analogous to maintaining your subject’s position under the center point of the frame as they move closer to the camera in real life.

As you can see up top, the subject was maybe in the spotlight one-third of the time. Unfortunately, the performance is far less spectacular due to the significant slowdown in the burst rate, which drops to barely 1.5 frames per second. We would ordinarily display 15 frames from a run, but the camera could only shoot nine photos due to technical difficulties.

Shooting in a Constant Stream

In single AF mode, our tests produced results near the 4.4 fps burst rate that Canon claims the M3 can achieve. As a result, you can take photographs in JPEG format at a rate of 4.3 frames per second.

In Raw mode, the camera only shoots a pitiful five pictures at 3.9 frames per second, and then there is a delay of four seconds before you can access the Menu. If you shoot in Raw and JPEG simultaneously with the M3, it will only be able to produce four photos at a rate of 4.1 frames per second. Additionally, there will be a wait of four seconds while the buffer is emptied.

When you switch to AF-C mode, your burst rate will drop significantly to around 1.5 frames per second (depending on your subject). When traveling at those speeds, the ‘lockup’ delay is only a few seconds.

Battery Capacity

The EOS M3’s short battery life is one of the most significant problems we’ve seen with the camera. The battery life of the M3 is the poorest of any camera in its class, according to the CIPA rating of 250 shots per charge. This rating places the M3 in a tie for the worst place with the Nikon 1 J5.

You won’t be affected by this if you only want to take a few shots when you’re at a get-together. But, on the other hand, it is strongly advised that you carry an extra battery with you if you are going out for the day, want to take a lot of videos, or plan to use Wi-Fi.

Image Quality

The most recent version of our test scenario emulates photography in both daytime and low-light conditions. You may switch between the two by pressing the ‘lighting’ buttons at the very top of the widget. The camera is left in its default Auto setting for the low-light testing, but the daytime scene’s white balance is manually adjusted so that the resulting grays are neutral.

Raw files require human editing to rectify errors. We provide three distinct viewing sizes, which are referred to as “Full,” “Print,” and “Comp.” The latter two viewing sizes allow “normalized” comparisons since they use matching viewing sizes. The ‘Comp’ option selects the camera with the highest possible resolution shared by the other cameras being evaluated.


The JPEGs have great detail generated accurately, and the color rendering appears exceptionally well-balanced. There is a slight warmth, but there is no trace of magenta. Even while it can’t quite catch and render fine details as well as the Sony a6000 can, it still looks pretty excellent compared to most of its competitors.

The noise reduction applied at higher ISO settings is slightly prone to smoothing away delicate information. It isn’t aiming to maintain edges as much as some of its rivals, which increases the possibility that the entire image may appear a bit softer than it is. Nevertheless, the performance as a whole is quite solid overall.


Looking at the Raw data reveals that a significant amount of information is being recorded despite the camera’s relatively low ISO (if you overlook the rather high levels of chromatic aberration produced by the 22mm lens). To extract the most data possible from the sensor, there is no anti-aliasing filter since a distinct color moiré evident in high-contrast details.

Even when re-scaled to a more typical viewing size, the high ISO performance is not spectacular and lags a bit behind its competitors.

Video Quality

The EOS M3 can record video in Full HD at 30p, 25p, and 24p. However, to record the footage at 60p, you must reduce the resolution to 1280 x 720. Your options for exposure are either automatic or completely manual; there is no between-ground. When using manual mode, you may adjust the brightness by turning the exposure compensation slider when auto ISO is engaged. Rack focusing may be accomplished with relative ease with the touchscreen and Servo AF.

Focus peaking, an adjustable audio volume, and a wind filter/attenuator are features available on this camera. In addition, there is a 3.5mm mic jack for recording audio separately from the camera. You will not, however, locate zebra patterns for checking exposure or a headphone jack for monitoring the audio volume. Neither of these features is there.

The quality of the video is satisfactory, although there is space for advancement. The hues, much as the stills, are pretty stunning. However, because there is not an AA filter present, everything seems a little grainy, and there are instances where moiré patterns can be seen. You’ll see in the demonstration video that the automated wind filter doesn’t do an excellent job, which is quite normal for cameras that have microphones already built into them.

This is a pretty wet example video, and we’ve included a little bit of baseball just for good measure (no pun intended).

In a world full of excellent mirrorless cameras, the EOS M3 just isn’t up to par with its competitors who are considered the best in their class. However, canon deserves praise for excellently designing the body and user interface and providing a comprehensive range of features in their products.

It’s a nice touch that the LCD can be tilted, and the fact that you can also have an electronic viewfinder is a definite plus. The variety of mount adapters will surely please those collecting vintage lenses. The image quality is satisfactory while not being mind-blowing; nevertheless, the lack of clarity in JPEGs causes them to appear to have a PowerShot-like appearance.
