Hi there A few months ago I purchased a used 7D and noticed that when I use an ISO above 400 I start to get severe hot pixeling.
I have since contacted Canon but they have told me that it would cost at least $250 for me to get the pixels remapped.
I am wondering if this would be worth while or if I would expect to encounter this problem again soon after or if it would help at all.

I am new to DSLR videography and I am hoping to find someone who has had a similar issue to what I have.

Thank you for your time

Cheers
Adam
