There is a rumour (I am English hence the spelling) that I will stick with Canon.
do not EVER
e for spelling something correctly
meanwhile, i've had my bad dealings with canon service, took my 3-month old 7D back to get fixed for dead pixels, and despite clear instructions saying where they were, i had to send it back a total of 3
times before they were gone. I could even tell they'd taken photos to test (the 2nd time) because the numbering was wrong. yet they still sent it back for me to return to them a 3rd time.
(then when i got it back after the 3rd, no dead pixels, AF on every lens didn't work. thankfully a 'restore to factory settings' fixed that)
then i rewarded them for that a few months later by buying a 70-300L. and my 7D rewarded me again by killing more of its pixels.
sometimes i think i'm gonna bail to another company, but i doubt they'd have any better luck...
