Hot Pixels - how do these numbers look?
There doesn't appear to be much information about acceptable levels for the inevitable hot pixels at longer exposures.
My 2 month old 60D is at the following levels (taken with lens cap on and after performing the manual sensor cleaning method):
ISO100 @ 10secs - 0 hot
ISO100 @ 20secs - 1 hot
ISO100 @ 30secs - 3 hot
ISO 800 @ 32secs - 5 hot
ISO 800 @ 16secs - 5 hot
ISO 400 @ 120secs - 8 hot
At this stage it is not a problem for me, as although I take star trail & other longish exposures, the RAW converter maps the offending pixels out. However it may become more troublesome in time, and would like to deal with it early in my 60D ownership (warrantee issues etc).
I'm also hoping this post will provide some context for Canon DSLR owners on other owners hot pixel rates.
