I've never used Precision Camera. Between Authorized Camera Repair and Canon repair, I've had no need to go elsewhere.
One of the things I like about the guys at Authorized is they are honest. They've actually told me to send some lenses I've brought in for repair to Canon because Canon would more than likely do the repair faster and for less money. For example, when my EF 28-300L needed repairing, the guys at Authorized told me, sure they could definitely repair it, but Canon will do it much faster and for less. They were right. Canon repaired it for $100 less than Authorized estimated the repair would cost and Canon had my lens back to me in just a few days.

Yes Authorized is one of the best.

FYI, Precision Camera is the main USA factory-authorized repair center for many of the major brands of cameras, did you know that. A lot of Canon warranty repairs are sent there, did you know that? Many Nikon and Sony warranty repairs also are sent to Precision, as well as many other brands.

Cheers and best to you.

I tried to send an EF 50 1.2 lens to Canon and was told it was out of date for repair. That's when I looked at Royal.

The only time a lens should be out of date for repairs is when the needed parts are no longer available. Some repair facilities buy used lenses just for their parts inventory. Canon does not do that. Several years ago my EF 85 f/1.2 was in need of repair. I checked with Canon and they told me parts for that lens, because of its age, may not be available but they wouldn't know until it was disassembled. That's when I found Authorized Camera Repair. I got lucky because they had a parts lens and the part I needed.
When my 28-300L died, Authorized Camera Repair told me that since the lens is still in production, Canon would have the parts and would probably do the repair quicker and cheaper. Authorized Camera Repair quoted me $750 for the repair and said they would have to order parts. I took their advice and sent the lens by overnight mail to Canon's repair facility in Virginia. They received the lens on a Wednesday and called me with a cost quote the next day, Thursday. I paid them over the phone and had my rebuilt 28-300L back in my hands the following Monday. Cost was $650.

You did not tell us the model II, III and what is wrong with it? It may only need maintainance which you can do yourself. Is the front/rear element lose and you are seeing AF issues on DSLRs? I am going to assume it is a II because III are fairly new, probably less chance of an issue and the original version is old and less people own those.

Here is how to resolve that problem.

If you have a problem with AF not engaging, there is a video for that. So I am just saying there are some things you can do that you don't have to send it in and if it is out of warranty and you are handy, you can save yourself some money.

Having seen one of those repair videos mentioned, I would say that anyone who can use a screwdriver will be able to repair the lens or the camera.

The video was about 45 minutes and I would be willing to do the repair myself if it was my camera. Perhaps you should have a look at the video.

Heather is right, the approach is not difficult. By dotting the parts for alignment on reassembly and keeping the screws for a part held on a small magnet to keep size4part straight takes the chilling-trill out of reassembly. Using a second camera to photograph the stages of disassembly is a great aid. Once you take the adventure, the confidence in your DIY repair is reinforced. Buy a "junk, Parts Only" lens and you have little to lose and lots to learn.

Do professional repair people have some special powers like magicians? No, the learn by doing.

Apparently you have never taken a complex auto focus zoom lens apart, then tried to put it back together and have it actually work. For one, you need a lot more than just a screw driver.

My Canon 70-200 2.8 II had the exact problem in the video. I did not notice it when it was on the R5 but when I put it on a dslr it had an AF issue.

I followed the video and it was easy. (there was also a Canon 400 2.8 as well where you had to go into the lens deeper )So yes I have taken a lens apart and put it back together and it worked. And it only required a screw driver. There are some other videos online that show other AF repairs that you replace shorted wires and other such things where you have to take the lens down to the second level. I would do those types of repairs before I sent it into a service shop in an far after warrantee situation.
