| Australasian Gannet Juv. EOS R5 with RF 100-500mm L |
Canon introduced the EF mount and the EOS line of interchangeable lens cameras and lenses in 1987. The EF electronic mount represented a complete break from the previous FD mechanical mount. Canon had a clean sheet on which they could design a completely new line of camera bodies and lenses with no legacy features which needed to be carried over.
In the film era this project proceeded in a fairly
straightforward fashion at least from the consumer perspective.
But then came the digital era and the product
catalogue started to get more complex.
We got EF-S crop sensor bodies and EF-S lenses to
match. But EF-S lenses could not be mounted on full frame bodies.
After a while along came mirrorless camera
technology. Canon’s first entry into
this realm was the EF-M system with a
different lens mount and a set of EF-M lenses exclusive to EF-M bodies.
A bit later Canon entered the full frame mirrorless
market with another new lens mount and
catalogue of bodies and lenses using the RF system.
Not content with that, in 2022 they released yet another line of crop sensor
bodies and lenses this time called RF-S. RF and RF-S lenses will fit on and
work on any RF mount camera thus far but RF-S lenses will not cover the full
frame sensor.
So now, in July 2022 Canon presents the prospective
buyer with a confusing model muddle
involving both bodies and lenses.
We have EF full frame bodies and EF lenses, crop
sensor EF-S bodies and lenses, EF-M bodies and lenses, RF full frame bodies and
lenses and RF-S crop sensor bodies and lenses.
But wait, it gets worse. Not only do prospective Canon
buyers have to select between different systems but even within the same system
there is a lack of coherence making the experience of selecting and using the
equipment un-necessarily complex and confusing.
We can consider the ergonomics and user experience of
a single model as a stand-alone and that is a useful exercise.
But my reading of user forums would suggest that
plenty of photographers own and use two or more camera bodies and several
lenses. For these people, of whom I am
one, it is really essential that one Canon camera have substantially the same
controls and user experience as another one on the same tier in the
price/capability hierarchy.
This is because we learn to operate a camera using
muscle memory, just like driving a car. Imagine the chaos if we had a car with
the accelerator and brake pedals transposed.
Camera makers do something similar with concurrent models leading to un-necessary
confusion.
Consider cameras and lenses which use the RF mount
which was introduced in 2018. This was
an opportunity to re-set the product catalogue with bodies and lenses having
substantially the same controls and user interface design.
But that has not happened. Right from the first RF
mount model, the EOS R, we saw designers messing about with the controls for no
stated or apparent reason. The EOS R featured a control module never seen
before or requested by anybody in the form of the multifunction bar. Most users were unable to find a use for this
thing and disabled it. But why was it there in the first place ?
The next model in the RF catalogue was the EOS RP.
This has a different form, different controls doing different things and a
different battery.
Then came the EOS R5 and R6 which are very similar but
both those models have a control layout which is sufficiently different from
the R or RP that switching from R5 or R6 to R or RP is confusing.
I have an R5 and an RP and find that whenever I switch
from one to the other I feel as though I have to learn what to do all over
again.
Then along comes the crop sensor R7 with a completely
new type of control module never seen before and never requested by anybody, in
the form of the concentric Multi-controller/rear control dial unit the clever
design of which ensures that the thumb will bear against and often move the
control dial when working the multicontroller. In the meantime the place where
the rear dial sits on other R series bodies is essentially vacant being host to
just an on/still/video switch which could easily have been located beneath and
protruding out from the rear dial as in the R10. What on earth were they thinking ?
Many keen bird/sports/surfing/wildlife photographers
will have an R5 or R6 and will want to add the R7 for more effective reach with
distant subjects. They will not be well pleased to find they have to re-learn
how to use the device when switching from one body to the other.
Neither will they be happy to find that sometimes when
moving the AF box they also inadvertently change exposure compensation or
aperture or shutter speed depending on what function was allocated to the rear
control dial.
It’s a mess which could and should have been avoided
simply by making each of these camera bodies the same size and shape with the same set of controls in the same locations
and functioning the same way.
The R7 has a box volume (w x h x d) of 1093 cubic
centimeters (cc)which is not significantly smaller than the R5/R6 which has a
box volume of 1190cc. So I see no benefit to the user arising from the
different shape and controls of the R7 compared to the R5/6.
But if the R5/5/7 each had the same exterior body and
controls that would provide a very substantial benefit to users.
What about the new EOS R10 ?
Box volume of the crop sensor R10 is 898cc which is
greater than that of the full frame RP which is 791cc. Not only is the RP
smaller than the R10 but it is wider which provides greater clearance between
the lens barrel and the fingers of the right hand. In early reviews of the R10
several users complained that their fingers pressed uncomfortably against the
barrel of some of the larger RF lenses which were used in the test.
I include the RP and the R10 in my proposed level 3
group (see below) of models which would appeal to amateur/enthusiast/upper
entry level users. On this basis Canon would make a lot of users happy by
giving all models at this level the same body shape, size and control layout
and making this as close as possible to bodies in level 2.
What about lenses ?
Unfortunately the same kind of muddle has developed
and is getting worse.
Some lenses have an AF/MF switch, others do not. Some
bodies have an AF/MF switch, others do not. Which prevails ? …..The switch on the lens does if there is one.
If you have a lens with no AF/MF switch on a body with no AF/MF switch you have
to enter a menu to select AF or MF. What
a mess.
My appeal as a consumer to Canon is….please make up
your corporate mind….either fit an AF/MF switch to every lens or none or every
body or none. Be consistent across the whole catalogue of bodies and lenses
with such a basic and essential function.
Likewise, some lenses have a stabiliser On/Off switch,
some do not have the switch although they do have a stabiliser. Some bodies have a stabiliser, some do
not Again my plea to Canon is please be
consistent across the model range. Locate a stabiliser On/Off control module of
the same type in the same place no matter what RF mount body or lens is in use.
I guess Canon is unlikely to do this across the whole
model range because of unit cost and marketing considerations, but here is a
suggestion which I think has merit and which could be implemented:
This comes from a user perspective. I understand that
Canon product development execs most likely consider themselves to be fully
engaged the enterprise of meeting user expectations but I think they could
improve their implementation of the project, on which by the way, the fortunes
of the entire corporation rest.
My suggestion has camera bodies allocated to one of 5 levels
in the price/capability hierarchy.
All bodies on all levels would have the same major
controls. These would include handle, shutter button, front dial, Fn button,
rear top dial, multicontroller (joystick), AF On button, lower rear dial.
All bodies at the same level would have exactly the
same body size and shape and external control layout. They would use the same
battery and the same accessory battery grip in the case of level 2 models.
The body structure might be different, for instance,
metal/polycarbonate and the ruggedness might be different, as might be the
sensor, EVF, monitor and processor.
This stratification system could work out as follows:
Level 1 Integral vertical grip units
These are the professional, high performance models.
In the RF mount catalogue this includes the R3 and as-yet-not-manifest R1.
These cameras come with “the works” as far as
controls. A pro photographer switching from an R3 to an R1 will want to find
the body and controls identical to ensure continuity of the user experience.
Level 2 Expert/prosumer units without
integral grip but able to fit an accessory battery grip. Models
in this group have IBIS and a high performance capability.
At the moment in this group we have the R5, R6 and R7.
As discussed above I would like Canon to give all
models at this user level the exact same size, shape and control layout. From
my perspective as a consumer and frequent user this would be highly desirable.
Why Did Canon give the R7 a different shape and
control layout from the R5/6 ?
Of course I don’t know but Canon has a long history
of dividing their product lines into thin
market segments so I guess that would be a factor. One problem with this is that the overall
market is now so small that subdivisions which worked well for Canon ten years
ago might be just a source of un-necessary and counter-productive diversification
today.
Level 3 Units with smaller form factor. Cameras in this group will appeal to enthusiast/
amateur/ aspirational yet budget conscious buyers wanting to step up
from their smart phone and experience
the challenge of camera photography.
These cameras do not have IBIS, they use a smaller
battery and do not offer an accessory battery grip.
Models in this group presently include the RP and R10.
The R sits awkwardly somewhere between levels 2 and 3. If I were in charge of
product development at Canon I would not be planning any direct replacement for
the R.
RP size/shape models with controls more like those on
the R10 would work very well at this level. In my preferred user world there
would be no difference between full frame and crop sensor models with respect
to exterior size, shape and control layout.
The size of a camera body is determined mainly by the
lens mount, flange back distance, handle, EVF, monitor, IBIS if fitted,
controls and battery. The size of the sensor has very little to do with it.
Level 4 Entry level models with lowest
level of spec and performance, some without EVF. This the lowest entry level for mirrorless
interchangeable lens cameras. Models at this level offer a small form, light
weight and a limited set of controls.
There are no RF mount models at this level yet but an
RF version of something similar to the EOS M50 and M200 could be possible.
I personally think cameras without a built in EVF are
an abomination to be avoided like the plague. But some people like them and
users coming from the smartphone world could well feel more comfortable with a
camera lacking an EVF. Until they want to accurately frame up photos in bright
sunlight of course.
With or without a built in EVF I would like to see all
models at this level have the same basic body size, handle and controls.
Level 5 Compacts and bridge cameras (fixed
lens models).
There appears to have been little or no R&D work
on fixed lens models over the last few years. However Canon still offers
several compacts each of which has a different shape, size, control layout and
operation. If Canon ever does resume development of fixed lens models I hope
that consolidation of design features and the user experience is part of the
project.

“But EF full frame lenses would not fit onto EF-S bodies.”
ReplyDeleteIsn’t it the other way around, i.e. EF-S lenses not fitting EF bodies?
HI Sami, Well spotted, thanks, now corrected.
