Greetings,
Has anyone here left product [+]Feedback for Canon? This would at least give the development team an opportunity to evaluate the behavior and determine if any functional changes were needed.
Product Feedback can be left by navigating to the Canon USA website, select feedback, then product.
I guess you may not have read what we wrote carefully, or you may have too much respect for the Canon brand so cannot see something. Please see the attached youtube link first:

What you mentioned is exactly how Panasonic, another mirrorless camera brand, supports manual lens ibis. Every time when the lumix camera turns on and no contact connection is detected (a contactless lens is inserted/no lens is connected), the camera will ask whether to use the current saved focal length or manually enter another focal length. The eos rf cameras has no prompts when they turn on.
Now we take a look on canon's side. In fact, Canon camera does save focal length after it is setted. Each shutdown-start process will not change the focal length saved here. As far as I know it works as designed on other rf cameras like the eos r6. It worked great with the same manual lens attached after the power off-on process. But if the user owns multiple manual lenses, the user must be responsible for changing the focal length setting themself after changing lense. But on the R7, the problem is that although the focal lenth setting value in the menu seems does not change due to the shutdown-starting process, its ibis actually fails. Severe shaking is easily observed when use digital zooming in to 10x. There are only two ways to correct this problem: 1. Enter the menu to turn off ibis, then enter the shooting interface and press the shutter halfway to lock the ibis system, then return to the menu to turn on ibis, and then it will work normally. 2. Enter the menu and re-enter the focal length, even if it is a closed focal length. Now every time I use a 25mm lens, I will change the 25mm in the settings to 26mm or 26mm to 25mm when I turn on the camera. 1mm is close enough to help ibis work correctly. I think this way is faster than the first way. I use 25mm 0.95 cf and when ibis is working normally, I can hold the photo clear and sharp for 3 seconds shutter speed, but when ibis fails, shutter speed must be kept above 1/60s. Here is a video that clearly shows the difference: https://youtube.com/shorts/reG5hbUlTmc?si=DBRxLbtSC1Lpv5GY
Let's sum it up: Canon never designed the system like you said to force the user to change the focal length setting every time the phone is turned on to avoid ibis failure - I quite appreciate Panasonic's design, if you use the same lense you only need half press the shutter to confim the saved focal length; Canon never design the r7's ibis system like now - From what I've observed, it doesn't appear on older rf cameras like the r6, but on newer cameras like the r7 or may even the r3. In other words: 1. Canon actually provides the crudest ibis manual lens support among all brands; 2. This crude design even does not work properly on the r7. The reason Panasonic provides better ibis manual lens support is simply because their autofocus is terrible and a lot of people will use cine lenses and give up on autofocus entirely, assuming without this support those video shooters(it's a big part of lumix users) would quickly abandon Panasonic and go; and Nikon has many old lenses with F mount, which drive aperture and focus entirely through body levers and motors. Nikon does not dare to take the risk of making old customers who use them unable to use them any more. I appreciate canon has excellent dual pixel af auto focusing, and seems they hope(or force) that all RF camera users will only use canon ef/ rf lenses, so they only provide a "exist" level implementation. Well, I understand such business logic. But what I can't understand is that such a simple system can go wrong! You said that if the user forgets to change the focal length and the ibis fails then it will be regarded as a mistake for you? Then what would you consider when I see that the focal length setting is completely correct in my r7 but the live view shakes violently then I think it is the poor performance of the Canon ibis system itself? If I hadn't seen some previous user reports, I would have simply assumed this was a performance issue! I would say this is a shameful deception!
