Why does Canon just have to make EOS R3 and R1 so big, and compromise portability?

[Zalkonian]

EOS R3 and R1 are only camera among the few Canon cameras that use latest stacked BSI type CMOS (I asume it's BSI since it's latest, am I right?) with low resolution for good low light performance what got me interested in considering it as an alternative Sony A7sIII. But sadly there always seem to be design problems and in the case of EOS R3 it is it's huge size.

I want to take a camera for bikepacking trips and mountain hiking so size and weight are important factors. There are camera clips to attachs camera's to backpacks such as Peak Design V3 but big Canon camera will just stick out a lot unlike say R6.

Why is it so big, due to battery capacity or some other important components that improve photo/video quality? I owned a Sony A7sI and it was amazingly compact for a full frame sensor camera. I had actually modified it to full spectrum for infrared and UV photography so I seen that there is very little space wasted inside the magnesium alloy/plastic chassis.

Some people do need larger battery capacity but it can be expanded by separate battery grip attachment to keep the camera as compact as possible and more travel friendly. New battery technology such as silicon nanowire batteries can help reduce battery size and weight.

Why do professional camera manufacturers just have to compromise quality and not design cameras as good as possible using for example front lit sensors despite charging many thousands of euros for them?? It would be easier to find the best fitting camera if they just learned from previous designs and used the latest technology.

I just got an email from Canon, informing me that my CF-R20EP Cooling Fan for my R5MKII shipped today.  I can't wait to get it and put it on so that my R5MKII with the RF200-800mm f6.3-9 IS USM lens will be better balanced and will be easier to handle.  😉  (I like a camera of weight!) I just can't figure out why some people find the littlest things to gripe about?!  Oh, the camera body is to big or to heavy?!  Go figure, they're the same ones that will complain about anything and everything cause they have nothing to do.  These types are not into photography.  They most likely have never been serious about photography cause if they were they would be out shooting pictures instead of comparing one brand over the other because of size!  Go shoot something instead of wasting time discussing the micro-weight differences between one brand over the next.  OOhh the canon is to big for me to carry.  Suck it up and stop snibling, Baaaawahahahahha  😆 🤣 😂

Reference CF-R20EP

That seems like a interesting add on, my older JVC GY-250U had an internal fan which worked well, but even with a fan it couldn't keep up with the full day sun in SFL, sitting on a tri-pod in full sun the camera would get so warm it was uncomfortable to touch and at a certain temp would self protect and shut down.

My solution was simple cover the camcorder with a white towel, it didn't block the cooling vent and greatly lowered the camera's temperature.

I do find it amazing SLR's can get so warm nowadays but like camcorders they are often parked on tri-pods in the sun.

Hi WCETECH,

I figured that I could use the CF-R20EP Cooling Fan for when the weather gets hot or when I travel to hot places.  As it is the R5 Mark II doesn't need it for photography as it has cooling vents that keep it pretty cool and has not heated up.  However, it is a good feature to have when shooting video. I figure that if I was going to get a Grip it might as well be one that will serve me more than just a battery grip..   lol

From what I can tell is the R5 Mark II use's a heat exchanger which is smart, it allows the major electronic components to be cooled without exposing them to outside air, moisture and contaminants, that way the electronics will stay cool without being filthed up.

That of course requires a larger body and a bit more weight, but in my opinion that beats a lighter un-cooled consumer level camera such as the Sony.

Now that wouldn't nor should it matter to the average snap-shooter who wish's to use a camera body versus a cell-phone, however to a professional who needs to "bring home the bacon" to get paid the additional weight of the R5 Mark II is a improvement over the old, not a problem.

What needs to be remembered is those of us in professional photography/videography are already used to working with large bodied DSLR's and heavier cam-corders.

The newer equipment while not as light as consumer equipment is still way lighter to us.

You should be looking at APS-C cameras from Fujifilm, like the X-H2S.
