p.1 #11 · Mark II Shutter, Canon Irvine | |
I don't think it's even necessarily a MTBF. Canon's literature has always said "shutter tested to 200,000 actuations" (starting with 150,000 for the 1D, when the prevailing "pro" standard before then had been 100k, and now 300k for current versions). It implies that they test the shutter for that many actuations and look for problems, but not that they test a large number of them until each dies, then calculate a MTBF.
As for the warranty, it's based on time and whatever they judge to be "normal use". It's good that we've seen instances of Canon replacing shutters that fail somewhat after the warranty period but with rather low actuations. However, the warranty clearly does not explicitly guarantee the shutter after the time has expired.
Glad they took care of yours!
