Canon R3 vs Canon R5 – Head-to-Head Comparability

The EOS R5 has proved to be a really profitable digicam for Canon since its launch in early 2020, main the way in which in full-frame digicam gross sales in Japan and serving to to maintain Canon worthwhile throughout a really making an attempt yr.

With the current hotly-anticipated launch of the Sony Alpha 1 and the current announcement of the Nikon Z9, nonetheless, Canon have lacked a equally specced flagship mannequin – till now, that’s.

So how does the brand new EOS R3 differ from the R5, and which of those 35mm full-frame sensor mirrorless cameras is the correct one for you?

We’re bringing you this in-depth Canon R3 vs Canon R5 head-to-head comparability that can assist you select between them.


The megapixel depend of the Canon R3’s sensor remains to be unknown, whereas the Canon R5 has a forty five megapixel sensor. We would be stunned although if the R3 had fewer megapixels than the R5 and likewise its predominant rival, the Sony A1, which has a 50 megapixel sensor.

What offers the EOS R3 a probably a lot greater benefit is the kind of sensor that every digicam has. The R5 has an ordinary CMOS sensor, whereas the R3 is the very first EOS digicam to make use of a Stacked, Again-Facet Illuminated (BSI) CMOS sensor (identical to the Sony Alpha 1), which probably interprets into higher low-light efficiency at like-for-like ISO speeds.

Canon are additionally at pains to level out they the brand new sensor within the R3 has been developed by Canon, and never by the market chief in sensors, Sony.


The Canon R3 makes use of precisely the identical Digic X picture processor because the R5, R6 and EOS-1D X Mark III cameras, which mixed with the brand new stacked BSI sensor permits the R3 to shoot at even sooner speeds for each stills and video.

ISO Pace

The native sensitivity vary of the Canon R5 is ISO 160 to ISO 51,200, which might be expanded to ISO 50 to ISO 102,400.

The ISO vary of the Canon R3 has not but been disclosed.


The Canon R5 employs the Twin Pixel CMOS AF system with a whopping 5,940 particular person section detection factors that cowl the body as much as 100% vertically and horizontally utilizing the Auto AF space choice.

The brand new Canon R3 has a “subsequent technology” model of Twin Pixel CMOS AF which tracks and focuses on the eyes, heads and our bodies of fast paced topics higher than some other EOS digicam.

Much more intriguingly, Canon have acknowledged that “it can add a brand new topic (but to be disclosed) to the digicam’s AF monitoring.”

We take this to imply that the R3’s Face/Eye detection mode may have the power to recognise and observe both people, animals, and for the primary time, particularly birds and deal with both their our bodies, faces or eyes.

Eye Management Perform

Maybe much more excitingly, the Canon R3 will assist you to choose and transfer the AF level with the look of your eye utilizing the digital viewfinder!

The EOS R5, and certainly no different digicam in historical past, permits you to deal with a topic just by taking a look at it by way of the viewfinder – besides for 3 of Canon’s movie SLR cameras, that’s.

The EOS 3, 5 and 50 all had an eye-controlled autofocus system the place you can calibrate the digicam to your eye after which choose a selected AF level just by taking a look at it. The EOS 5 and 50 solely had 3 AF factors, so it labored fairly reliably, whereas the EOS 3 had 45 AF factors which made the system extra hit or miss.

Now the brand new Canon EOS R3 is trying to drag off the identical trick just a few many years later, however presumably in a extra refined, extra correct means that is appropriate for probably the most demanding skilled customers, billing it as “an AF management system prepared for the twenty first Century”.

Burst Capturing

The R3 ushers in a “a brand new period of excessive velocity efficiency for professionals”, a minimum of in accordance with Canon anyway.

The Canon R5 can seize photographs at as much as 20fps with the digital shutter or 12fps with the mechanical shutter for 170 JPEG frames, 83 RAW or 130 Compressed C-RAW recordsdata.

If you’d like even sooner burst taking pictures, although, the Canon R3 takes issues to a different stage by with the ability to shoot at 30fps with the digital shutter with full AF/AE monitoring and minimal picture distortion.

Climate Resistance

The Canon R3 presents the identical stage of sturdiness and mud and moisture resistant weather-proofing because the flagship EOS-1D X Mark III DSLR digicam, which shares the identical strong, weather-sealed development of its predecessor.

The EOS R5 additionally has wonderful weather-sealing that’s much like the Canon EOS 6D Mark II’s safety, so not on the identical stage because the EOS-1D X Mark III and by affiliation the brand new EOS R3.

Built-in Grip

The Canon R3 has the identical built-in grip with duplicated vertical controls that EOS-1D sequence customers have loved for a few years.

While professional shooters will largely be delighted, some folks could discover the additional bulk and the dearth of flexibility extra off-putting.

Becoming the non-compulsory BG-R10 battery grip to the R5 achieves a lot the identical factor as having an built-in grip, extending battery life and offering vertical controls while sustaining the identical stage of resistance to mud and moisture, however with the choice of eradicating it if required.


The Canon R5 has a fairly unbelievable stabilisation system, It options 5-axis in-body picture stabilisation (IBIS) which supplies as much as 8-stops of IS when utilizing the digicam with sure appropriate lenses.

The precise particulars of the brand new Canon R3’s IBIS system have not been revealed but.


The Canon R5 has a really spectacular 5.76M-dot OLED digital viewfinder with 0.76x magnification and a quick 120fps refresh fee.

Aside from the eye-control AF characteristic, we do not know the rest concerning the R3’s viewfinder but – perhaps/hopefully it can use the identical superlative 9.44M-dot OLED Quad-XGA unit because the Sony Alpha 1?

LCD Display

The Canon EOS R5 has a well-known 3.2-inch LCD panel with 2.1 million dots of decision, unchanged since its debut on the EOS R digicam.

It is a absolutely articulating display that may be flipped out to the facet, rotated to the entrance, and folded in opposition to the again of the digicam to assist defend it.

We would count on the display on the Canon R3 to be of higher-resolution, but it surely in all probability will not flip out to the facet and even tilt, identical to the fastened display on the EOS-1D X III.


The Canon R3’s video specs have but to be revealed, however we might be very stunned if it did not a minimum of match the R5.

The R5 has a headline-grabbing 8K video mode, which together with the Sony A1 makes it one of many solely two digital interchangeable lens cameras to supply this characteristic at current.

The Canon EOS R5 presents 8K inside video recording as much as 30p (non-cropped) in 4:2:2 10-bit Canon Log (H.265) or 4:2:2 10-bit HDR PQ (H.265), along with 4K video at as much as 120p.

When taking pictures 8K/30p and 4K/60p, the EOS R5 can file for as much as 20 minutes earlier than it overheats – we might hope that the bigger physique and the unfavorable suggestions that Canon have acquired concerning the R5 would imply that the brand new R3 does not endure from over-heating.

Reminiscence Playing cards

As you’ll count on from an expert digicam, each the EOS R5 and the 1D X III have twin reminiscence card slots, however whereas the R5 has one slot for high-speed UHS-II kind SD playing cards and the opposite for ultrafast CFexpress playing cards, the 1D X has two CFexpress slots.

So we might in all probability count on the R3 to comply with the lead of the 1D X and have two reminiscence card slots that each help CFexpress reminiscence playing cards, moderately than the combined media strategy of the R5.

Battery Life

The Canon R5 makes use of the LP-E6NH battery which presents a lifespan of 470 photographs when utilizing the digital viewfinder and 490 photographs when utilizing the LCD monitor.

The EOS-1D X III differs by utilizing the LP-E19 battery which is CIPA rated to 2850 photographs with the optical viewfinder and 610 photographs with Stay View.

We’re unsure but which battery the brand new Canon R3 will use – will it preserve backwards compatibility with the R5 or inherit the LP-E19 battery from the 1D X sequence?

Cell File Switch App

Canon are additionally introducing a brand new Cell File Switch smartphone app to switch photographs and velocity up workflow while on the transfer utilizing cell community providers moderately than wired LAN gear. It’ll initially solely be accessible in June for Apple gadgets, with Android help to comply with at a later date.


Within the UK the Canon EOS R5 is priced at £4,199 physique solely and within the US it prices $3,899.

The EOS-1D X Mark III retails for £6,4999 / $6,499, which maybe not fully coincidentally can be the identical value of the Sony Alpha 1.

With its predominant mirrorless rival and related flagship DSLR sibling each costing £$6.5K, we might count on to see the brand new EOS R3 be a part of them on the similar value level, so it can signify a giant bounce up from the extra “reasonably priced” R5 mannequin.


We do not know the total particulars concerning the new EOS R3 but, however what we do know clearly positions it a rung above the R5 in Canon’s full-frame mirrorless digicam lineup.

With sooner 30fps burst taking pictures, a stacked BSI sensor, extra superior AF system with an modern eye-control perform, professional-level construct high quality and weather-resistance and an built-in battery grip, that is clearly the mirrorless equal of Canon’s most superior DSLR, the EOS-1D X Mark III.

So what do you suppose? Based mostly on what we all know up to now, would you select the brand new Canon R3 or the Canon R5, and why? Depart a remark under!
