Finally sending in my Mark III for the Mirror Fix

I have been one of the folks that has been very happy with my Mark III and never had any AF problems shooting mostly sports with it. I also owned II and IIN bodies and my Mark III outperforms them in every way, especially AF. I've never done the mirror fix and not even updated the firmware. I am almost a year old and so my warranty is about to expire. I decided I would go ahead and send it in for the fix to a) get an extra year warranty, and b) hopefully help my resale value if I ever sell it.

For those that have done this fix, is there any risk that Canon will mess my camera up in doing this? I am hoping that by waiting so long that they have this down to a science. I'll be keeping my fingers crossed when I send it away.

What are your options - have your local camera shop do the repair - I don't think so - why worry over something you have no control over.

Yes!

Not the same thing... but I had a 24-70 that they put a nick in the body... I got it replaced with a new one though!

mess up, no, screw up your lens calibration, yes. they will return your camera in the best possible condition, even if it means having it shipped halfway around the country to repair anything else they find. no risks i've found

While I follow your reasoning in sending it in, I follow the "ain't broke, don't fix it" motto. If it has been performing fine for a year and you know how well it should be since you have owned the II and IIN, why send it? You already state it is better at focusing than the II or IIN. So.... why be without the body? Just my thought.

Because it extends the warranty for a year and nobody would buy a used MkIII that wasnt blue-dot OR had the sub-mirror repair done.

There you go... that's exactly the two reasons. Regardless of all my posts proclaiming my Mark III has been fine, no one would buy it used at a fair price without the fix. And the warranty extension is worth it alone. And, since I've not cleaned the sensor in a year of steady use with many lens changes (got to love that automatic sensor cleaner... works like a charm), it could use a good cleaning.

My options would be not having it done.

I would probably not be that bothered if it came back with a nick, as long as it works properly. I use my gear and it gets bumped around a bit in the process. The last thing I sent into them was a 24-70 that was ironically broken in half from a fall.... snapped it right off at the mount. It came back and then the zoom ring completely failed about 3 months later. But that was probably latent damage to the mechanism during the tumble.
