The RF 35 f/1.4L VCM aperture ring will work for photo work on Canon’s next generation cameras

In the end, it's a second electronic control ring. We don't know how the control ring communicates with the camera. We don't know how it communicates with the video or stills side of things. We don't know how the hardware and communications are handled between the two modes in the cameras.

Adding a second electronic control ring may not have been on table when the current line of cameras were developed. Video and stills have been two separate teams in software development in the past, I imagine Canon has worked hard to bring those two teams closer together along with more aligned engineering (See the R5 C and Wifi communication that is built into the camera, but only really works for stills). Again, we don't know.... they don't tell us.

Unless someone can break down the engineering on how all that works inside of the camera, I don't think it's prudent to suggest it's simply Canon's inability to write good software.

The AF magic of the EOS R3 and other cameras are certainly fine examples of Canon's software development ability.

The EOS R line is evolving to meet new demands in the market, and sometimes you're not going to see things you may want to do down the road.

There are only two lenses in the RF line-up that have the aperture ring. It could also simply come down to "What's the point?", let's focus our resources and manpower on the next generation of cameras and not spend those resources on a what would likely be a benefit to a very small segment of customers. You still have the control ring that can be set to aperture.

How many people use the the existing control ring? For what control? It took me a while to utilize it, but I don't use it for aperture, I still prefer doing it the same way I have always done it.

Seriously? It does not work in photo mode? I was not aware of this limitation. Canon introduces this new RF mount, protects it with patents, and a working aperture rings becomes a software feature for future cameras only? Time to look somewhere else, I guess...
The clickable Control ring allows the aperture to be set. Nothing has changed/lost.

It's the anti-Canon shills making a fuss about the aperture ring in stills mode...

Seriously? The mere existence of this lens prevents you from setting the aperture the way you used to?

I wonder how Canon handles the situation where you're in Tv mode and you decide to twist the aperture dial on the lens. Will it change the aperture to match the dial, will it silently ignore it or will it pop up annoying warnings about you holding it wrong?

only Canon lens with focus shift problems is the 100 mm macro.
No, it's not:

No, it's not:
I've been using this lens many many times.
At various apertures. If there is an issue, it should be at apertures not commonly used for macros, like F/4 - F/5,6.
Anyway, I didn't notice one single issue, neither with macros, nor with more distant settings.
If you still hesitate, give this fantastic lens a try, I bet you'll end up buying it.
Meanwhile, my perfect leica R 100 F/2,8 sleeps unused in a cupboard. This says it all...

As someone mentioned in another thread: The last Canon lenses with an aperture ring were FD lenses. I’m curious: how have you managed so long without an aperture ring on EF and RF lenses?

It's a great feature on Sony's lenses -- but those lenses have a switch to allow click or non-click or to disable the ring entirely. If Canon's ring won't have strong clicks you can feel, I don't see the value for stills shooters.

I hope Canon keeps focussing DSLR style, always open , no matter what aperture you\'ve set, and stopping down only when you take the shot. Please not the Sony-way , focussing with the set aperture.
Sony bodies have a setting called "Aperture Drive in AF" that allows you to select:
"Focus Priority" to keep the aperture open for faster focus and then close it for the shot.
"Silent Priority" which keeps the aperture set to whatever you have it set to during AF (I guess what you were referring too).
"Standard" which is a mix between the two when you are in low light and the camera needs the aperture open for more accurate focusing.

So yes, DSLR Style Focusing if you would like it that way. That is what I have mine set for. To be honest I can't really say I have ever heard a peep from the lens's aperture opening and closing so I am not really sure if Silent is in there for maybe third party lenses that might be loud.

I really hope they don't use those specific terms to define aperture because they are incredibly unintuitive. But it probably explains my loathing for Sony if they do.

Now that the RF system has been around since late 2018, hopefully the next generation of RF bodies will be the end of "You need this particular RF body to use this particular feature with this lens" Some people like to use or only have the budget to buy quality lenses rather then upgrading camera bodies every generation.

Yes I do understand it could be due to a hardware limitation but hopefully these limitations will be worked out for the next gen and everything will be compatible for all future lens features (Except for VR or other unique lenses which require high MP etc)

This whole control ring bugs me. I'd frankly prefer to have every lens $20 cheaper and 20g lighter and a few mm smaller and simply not have it. The camera's totally covered in controls already, including 3 rotary controls which is enough for shutter/ISO/aperture, or any two of those plus exposure comp.

But since we have this control ring, I have it set for aperture.

So now for just one of my lenses, I'll have TWO aperture rings, when I actually would prefer: 0.

I don't mind having one on the grounds that other shooters may well need one. But no-one needs two.

And we totally need a no-click setting. I imagine an electromechanical way to have clicks or not might be a little complicated and expensive to engineer, but doing it once then just putting it in every lens shouldn't be expensive per unit.

Only the R6 and up have 3 dials, the R8 o
has 2 and some of the APS-C bodies only have one.
