Since I showed that the 7D AF could indeed lock onto subjects in conditions much worse than what was posted originally to rag on the 7D AF, it is a natural inclination to immediately attack the IQ, which is pretty easy for a post-sunset, ISO 6400 slightly underexposed shot. At those ISOs, you better make sure you have nailed exposure properly.

I don't know anyone who would even use ISO 6400 on the 7D. The pros I shoot with in the field wouldn't even go over ISO 800 when the 7D first came out. They quickly jettisoned that camera for a 1D series body or 5D II's.
As for 7D AF, there have been an unusual number of complaints (many here on this forum).
I just posted a link to RAW crops. One looks blurry, the other looks sharp. Care to guess which one the 7D is?
