Hi, true 4 pgs = 80 posting may not be distinct case count of err 99.
Also very true, I worry coz I have no idea what it is about and I about to invest 3K into it. Hence I am here looking for indications from all the experts here.
Not condamning any brands, I really like the 550D after playing with it vs the Sony and reading reviews, everything points 550D.
I just worried about buying another stupid product like my XPS laptop with NVidia 8400 GS that burns and need to change Mobo....
Trying to survey as much as possible, feedbacks from the public... and see if anyone out there has had bitter experiences with Canon :-)
Cheers

Precisely. Cant expect much due to the big ass glass. 1D series will help to boost the focusing a little.
85L and 70-200 price gap is kinda far away
Where did you bought yours from? Shashinki? if yes, send back to them to claim. I bought 4 sets of 4x Powerex 2700 from Shashinki and face the same problem. A year later they told me there's
one batch facing manufacture defect. I sent back and they replaced  4 brand new sets of Imedion for me. up for Shashinki's service!

I'm not sure. Just had the same symptoms with giaogiao. Contacted the seller and he offered an exchange. 

Works on all EOS models with IR?
