Canon RF 200-500mm f/4L IS USM confirmed, likely in Q4 [CR3]

[Loswr]

I had a confusion about that, and a while ago emailed Rudy Winston my concern and he replied that:

1st mode is built to stabilize horizontal motion when panning.

2nd mode is to stabilize vertical motion when panning.

3rd mode is for a higher level of stabilization, but on one direction only vertical, same as mode 2.

You might be right about the literature but to my experience with what "Rudy stated" in his reply to my questions the system has been working on me in 100%

If you’re saying that for you Mode 1 IS corrects only horizontal motion and Mode 2 and 3 correct only vertical motion, then either your lens is defective or you’re not conducting proper tests.

Also, note that ‘panning’ doesn’t mean just following a moving subject, it also means using a slow shutter relative to the motion. For example, when I’m moving the lens to track a bird flying across the frame and using a motion-stopping shutter speed (typically 1/2500 s), Mode 1 or 3 is best for that because that’s not panning. An example of panning would be using a 1/30 or 1/15 s shutter speed while tracking a kid riding a bike. The idea is to move the camera at an angular speed matching the subject, so the subject is sharp while the background has motion blur. That’s where you need Mode 2 IS.

But the point is that in any panning situation your body move up and down too. Nobody has absolute straight constant movement while moving along the x axis.

Sorry, but this is beginning to seem pointless. Of course that’s the point of Mode 2 – stabilizing the axis perpendicular to the one along which you’re intentionally moving the camera. But Mode 2 isn’t limited to pitch (‘vertical’) stabilization, it detects the direction of purposeful motion and stabilizes the orthogonal axis. So if you pan a model rocket taking off, or a bicycle rider with the camera in portrait orientation, both of which are ‘vertical’ to the camera, Mode 2 IS will stabilize the yaw (‘horizontal’) axis only.

The bottom line is that your statements about the way Canon IS modes work are wrong. I’m sure Rudy Winston knows better, and you’re misinterpreting his statements. As I said, if you believe that the IS mode selection determines the specific axis of stabilization, you’re just flat out wrong. IS mode selection determines the number of axes stabilized – pitch and yaw for Modes 1 and 3, pitch or yaw for Mode 2.

 

[Dhido]

I do agree with you, this is pointless.
I'm extremely satisfied with the results I'm getting with what I've gotten from Mr. Winston.
Tks for the interaction.

IS systems on cameras and lenses may actually hurt your panning technique

The new Panning Assist is basically a cheat code anyway.

In a way yes, you may say that.

Here is an even longer video featuring Rudy Winston:

So, take that!

 

[Loswr]

Sorry, how is a video from Rudy Winston on autofocus relevant here? We were discussing IS. Can you provide a time stamp for when he discusses IS Modes? Could it be that you’re confusing IS Modes with AF Cases?

Perhaps it isn't revelant to you but to me it is simply because it shows his vast knowledge and his technicality, therefore when he shares his "personal" experiences people like me put it to the test to confirm it.

My question was how is it relevant to IS modes? You replied to a post on IS modes with a video on AF.

Q: What is the square root of four?
A: Tangerine

Regardless, I see no point in further replies to you. Happy shooting.

"I doubt that’s what Rudy Winston stated," it is contrary to everything Canon says about IS.

Here is what they say:

Here's why Rudy Winston popped up in the thread, I'm beginning to believe there're limitations when debating certain topics.

If only I could understand what you're saying...

Unless you read the entire thread it'd be nearly impossible for you to understand.

I've read the entire thread. And I still do not understand your answer...Sorry.

@Dhido

Does Rudy talk about IS in the video you posted ?
If so, please let us know the timestamp, so we don't have to watch the whole video.
Thanks !

I'm getting the notion that there's an absence of reading comprehension.
I'm sorry but I cannot teach that.

Comprehension requires there to be meaning in the first place...

Not finding the meaning of what is read is a direct consequence of not having the ability to understand what is read, thus constituting an integral part of comprehension. Got it!
