Several months ago, Canon announced via email that they were offering PRECISION FOCUS ALIGNMENT for the R7. For DLSRs, this was an adjustment that could be done by the owners. However, R7 (possibly other Rs) have to send the body along with lenses to Canon for service.

Im just curious, has anyone actually sent their cameras/lenses in for this service? If so, please share your thoughts… cost, etc.
 
I have not sent mine in, but have thought about it. I did go through far enough to get the pricing. $89 for the R7 and $289 for the RF 100-500. Yikes!

I guess if I was convinced 1 or both were off it would be worth it.

The problem is - if you correct the body with one lens, will it be accurate with a different lens? Abd if you correct c the lens, will it be accurate in a different body? No desire to go down that rabbit hole!

I don’t think it works like that. Each setting for body/lens is independent of other body/lens settings. No overlap that affects other lenses. However, pics53090 made a good point. The cost may increase with each different lens you send in?

That would be an excellent question for Canon. I suspect any corrections are electronic, not mechanical, and would be tied to the serial numbers of the devices involved. Just as lens corrections can be built in for specific products (e.g, the RF16 and RF 24-240), my assumption is that they can do a custom correction for an individual item within the product line (assuming the camera and lens are modern units that can communicate serial numbers -- your old adapted FD lens probably won't work).
 
That's strange...I thought focus calibration was a thing of the past when mirrorless was introduced. I have not had one single lens with AF issues since I migrated to ML and that includes some old Sigmas from 2009 - which were hit-and-miss on DSLRs.

My R7 has no issues either (although I have heard stories that some encounter issues in some situations)

Interesting.

Well then why quote separate prices? What’s the point of calibrating a body, without a lens?

Canon actually recommends sending in your lenses with the body, although they do let you choose an option where they just adjust the body or Lens to a "standard" that Canon has. I will say I was surprised at the price to do this on the RF 100-500.

I think that an issue is more likely on a Lens instead of a body, at least when talking about mirrorless bodies. As lenses get used it is likely they would need a bit of tuning, especially a zoom lens.

Yes that interesting indeed. One main reason I switched to ML was to avoid MFA which I have always hated. Since ML does not suffer the variation of a mirror assembly and focuses on the sensor why is there a need for this? I always used LV with my DSLR’s as a start point to see how it compared to mirror assembly AF.

I too have not had any issues with either my old EF lenses which I sold or my new RF lenses. There may be an issue with a body or a lens but if both are within spec and are not having any other issues why would they need to go in together? I can see the need for that with a DSLR.

If someone suspects there is a problem and the gear is on warranty just send that piece in and get it checked out for free.

I used FoCal for many years for my DSLR’s. You can’t MFA an ML but FoCal can analyze performance. It’s what they state anyway. I wonder if someone has concerns that would be a cheaper option. You’d also have some ammo if you have to send your gear to Canon.

Yes electrical adjustments may be like MFA on DLSR. Specific to the lens that is attached. I’ve sent in DSLR only and Canon made electrical adjustments to it and it came back much better. I just asked to put the body in spec. MFA didn’t completely resolve the issue. It bounced back and forth between + and - too much. With DSLR’s there is very sight bounce even when perfectly calibrated. It’s the nature of a mirror assembly

Since 2005 I have only sent one lens in to Canon. An EF 70-200 2.8 II. If needed about +15 at 200mm. Canon found an mis-calibrated board. It worked at +15 but I didn’t order a lens that baldly out so I felt it was their responsibility to fix it under warranty. Especially with how much I paid for it.

I would think you wouldn’t even notice that on an ML but that was pretty extreme and not the norm for a Canon lens. Or maybe you would. I don’t know enough about that part.
 
Why specifically the R7, why not with other R cameras?
Mentioned that in the 1st post.

Interesting that few if any have sent their system in for calibration.

Actually, it is for all cameras, not just for RF. I think the OP just mentioned R7 because that is what he has. If you follow the link he included, you can see all the information. I even went as far as putting in my camera and my Lens just to get what the price would be, which I posted earlier in the thread.
