The long awaited Canon R1 and R5 MkII cameras were announced on July 17.  As a bird, nature, scenic and architecture photographer the 24MP R1 is of no interest personally.  The 45MP R5 MkII, on the other hand, delivers many new capabilities and performance upgrades that fill a gap in the feature list of the otherwise ground breaking original R5, the industry's first unicorn camera at 45MP and 20fps.  Below we list the more obvious features that will benefit us directly for the things we like to photograph.

There is much more, especially for Canon's prime markets, sports shooters, photojournalists and videographers, but since we don't do sports, events or video those are not listed.  Having said that, there were a few items that didn't make the cut, and those may pinch a bit at times.  Only field experience will determine just how much of an impact the latter will have.

Noteworthy features

  • Retained highly useable R5 body design

    • Shape, LCD, botton and dial design, menus

  • 45MP stacked BSI sensor

  • Blackout free viewfinder during burst

  • 30 frames per second max burst rate with electronic shutter

    • Adjustable

    • Increased from 20 fps on R5

    • Full 14-bit files vs 12-bit R5

  • Pre-capture of 0.5 seconds on shutter push

    • Once buffer is full the camera locks up until the buffer is written to card

    • Sony high end cameras continue to shoot, albeit at a slower rate

  • No zebras for overexposed areas

    • Available for movie recording; why not stills?

    • Almost universal on Sonys, even compacts

A Brief Comparison

When Canon stopped making two pro 1D series bodies, 1D for high frame rate and 1Ds for high(er) megapixels, we opted to move to the 30 MP 5D Mk IV DSLR for genres where resolution was more important than action.  When the R5 was introduced in 2020 its announced capabilities convinced us to immediately sell off our 1Dx IIs and 5D Mk IVs even before first shipment.   And the R5 has not disappointed, providing AF across the full frame, access to unicorn-like high megapixels and high frame rate at the same time -- and, at long last three dials with which to control the entire exposure triangle.

However, it wasn't perfect.  The R5's ~16ms electronic shutter readout time exhibited significant rolling shutter with accompanying viewfinder blackout.  This meant that 20fps was not available for many sports and action types.  For instance, baseball bats became bananas, not a good look.  Also, there were a number of nagging electronic shutter deficiencies, two of which stood out: 12-bit RAW files and lack of flash support.  Together, all these shortfalls added up to a less than perfect camera for certain uses -- albeit on balance the pluses far outweighed the negatives for my uses, even relative to Canon's pro 1D DSLR series offerings.  At an opening price of $4299USD (compared to $3899 for the R5) it should be better.  Still, it's a difficult ask with Nikon's 45MP Z8 currently selling for $3499.

Needless to say, the R5 Mk II follows the R5's tradition of excellence while adding plenty of additional value.

As the summary table of key metrics suggests, and leaving aside ruggedization aspects, the R5  Mk II can compete as both an action camera and a general purpose camera -- especially for our personal use cases, birds (with limited action) and nature, scenics, architecture and portraits.  In adddition to the above upgrades, a few small R5 annoyances have been fixed:

  • Drop in burst frame rate as battery level declines

  • Inability to turn off single point AF selection option

  • Non-adjustable 20fps burst rate in electronic shutter

How useful is it?

Every feature in the first list will be of direct benefit.  Each represents an improvement over the original R5, which nonetheless was by far the best camera I've ever used, in features, performance and ease of use -- including also almost every generation of 1D and 1Ds series DSLRs.  As such, the R5 Mk II will become my standard camera for action, birds and other wildlife used in combination with "big white" long telephoto primes.  The original R5 is no less capable than it was before and will thus remain in use for architecture and travel, primarily used with our stable of standard f2.8 and f4 zooms, ranging in focal length from 10mm to 200mm, and also with our tilt-shift lenses.

But, how limiting are the shortfalls?  Price is a disappointment but perhaps inevitable.  Canon may be trying to recoup its seemingly belated stacked BSI sensor R&D investment.  The 6.3ms sensor readout time is the slowest of any full frame stacked sensor currently on the market -- despite the fact that it is the newest.  Yet, since I don't do professional sports (tennis) anymore it is likely not a problem for my one action genre, bird action sequences, including flight and feediing activities.  Nevertheless, it is a discouraging commentary on Canon's struggle to catch up.

In practical terms, the hard buffer limit likely will have a bigger impact than readout speed, particularly with heron and egret fishing scenarios.  Finally, the lack of zebras for stills is simply inexcusable at this late date, particularly when the very same camera offers zebras for video recording.  Since these are almost certainly not hardware limitations one can hope that they will be addressed in future firmware upgrades.

All in all, as excellent as the camera is, it seems a bit compromised in a few important areas, especially given Nikon's Z8 capabilities and price point.  The unflattering suspicion lingers that if Sony hadn't come along Canon would still be pushing out 500nm FSI sensors with off-chip ADCs -- and 1% improvement upgrade cycles would be marketed as revolutionary technological triumphs.  So, yes Virginia, the infamous Canon cripple hammer lives on, albeit swung with a bit less force these days.

First use update after the break below.

Update 21 August 2024

The beast, AKA R5 Mk II, arrived yesterday afternoon.  By this morning buttons, dials and My Menu settings were first cut configured for wildlife, birds, sports, aviation and other action use cases.  The first field test, with tripod-mounted 600mm f4, hoping for birds to land at a birdbath as a test of pre-continuous shooting, took place thereafter on a sunny afternoon.  Sadly, no birds appeared.  However, the session was not without value as far as feedback is concerned.  More so, in fact, than I expected.  Below follows first impressions vs the noteworthy features introduced above.  Note that heat ventilation vents has been added to the original list -- and therein lies a tale, although not necessarily a good one.

Noteworthy features Assessment so far

Retained highly useable R5 body design

Ergonomically the 2020 R5 is by far the best body I've used.  Comfortable to hold and operate, with three dials to control the exposure triangle and sufficient programmable buttons to cover major actions.  The R5 Mk II changes a few things, and most do not detract.  There are a few, however.   First, the updated camera carries forward the smallish rear buttons -- they are too small and too similar for easy separation by touch.  Second, the full frame tracking selection has been moved from the list of AF areas to a separate selection.  With the R5, we programmed the AF-ON to toggle between single point and full frame eye tracking,  instant switching for action with a single button push.  That is no longer possible, and the loss creates a problem since all alternatives require multiple button pushes.

45MP stacked BSI sensor

Provides faster readout, which should reduce rolling shutter distortion.  Remains to be tested.

Blackout free viewfinder during burst

As there were no cooperative backyard birds, tthis remains to be evaluated.  However, activating this feature does turn display simulation and OVF simulation off.

Adjustable electronic shutter burst rate with maximum of 30 frames per second. 

A 50% increase over the R5's fixed 20 fps in electronic shutter.  And, the ability to adjust downward is a welcome improvement.  On the other hand, the number of duplicates and non-keepers can multiply drastically if one isn't careful

14-bit files vs R5's 12-bits

Theoretically, should result in increased dynamic range, possibly offset by the adverse impact of stacked sensor characteristics.

Pre-capture of 0.5 seconds

Major new capability for capturing unexpected action. The down side is battery drain and possible overheating.

Flash now available with electronic shutter

Enabled by the stacked sensor's faster readout, this is a significant upgrade to R5, which could not use flash with electronic shutter.  Not surprisingly, pre-continuous flash shooting is not available.

Additional subjects recognized with claimed stickier autofocus

Brief testing seems to confirm that the AF is indeed stickier, although much more experience will be required to determine just how much more effective this upgrade really is.

Evaluative metering is AF point-linked

This seemingly innoculous upgrade is in reality a significant boon to getting properly exposed images.  Theoretically, it should produce more accurate exposures in tricky lighting.  And, in early use it does exactly that.

Depth of field simulation

This works well, and I've left it on by default.  But, it does come with restrictions.  Turning on OVF simulation (makes use of the OLED viewfinder's increased dynamic range) turns display simulation off, and turning on Blackout free display turns both off.

Eye control (if it works)

Glasses, cateract surgery and dry eye problems make this problematic. However, it may be accurate enough to pass off a specific subject to the eye detect and tracking algorithms.  More experience needed to determine limits.

Body ventilation vents to exhaust excess heat

This isn't a panacea.  The first outing ended in an overheating shutdown, something that never happened in four years of R5 shooting.  There were perhaps three factors contributing to the problem.  First, we equipped the R5 Mk II with a battery grip, which obscures the bottom plate heat exchange input vent.  Second, the camera was exposed for a couple of hours to direct afternoon summer sun.  And third, although no birds appeared, a considerable time was spent in pre-continuous shooting mode, during which time the sensor worked overtime to keep its 15 frame half-second pre-burst refreshed.

Despite not finding a suitable subject during the two hour test, a couple of overvations merit mention.  First, the approach to setting the camera up has been to arrange as many settings as possible as toggles, supporting starting in one mode and switching quickly to another with a single button push.  For instance, there are only two viewfinder display options -- standard view with a few exposure parameters at the bottom and a second with full information plus level and histogram.  A quick toggle allows for checking exposure (zebras would be much better) and then returning to a less cluttered view.  Likewise, two nearly identical custom shooting modes, differing only by the on/off status of pre-continuous shooting, allows for switching to pre-capture only as needed.   That much seems to be working well.

On the other hand, the overheating after two hours of mostly standing around is troubling.  Since my most intensive use is in the summer, chasing birds at refuges, this will bear close scruitny in the future.  One must add that it's doubly troubling to realize that the design of the vertical battery grip accessory blocks the very ventilation ports designed to prevent this problem.  What gives with that, Canon?

Finally, now that the camera is available and testers can examine performance metrics such as noise level and dynamic range it appears that there is a (very) small penalty, in those two in particular, vs the original R5.  The implication of this is that for those not concerned with action and low readout speeds, there may be little incentive to upgrade.  We tend to concur with this supposition, and in fact we are keeping our R5s for general purpose genres such as events, architecture and scenics.   Meanwhile, the R5 Mk II appears to be simply better for action oriented genres where rolling shutter would otherwise be a problem.  As always, horses for courses.
