Well...I got my 6D...and the Wi-Fi was DOA. The rest of the camera worked well. I did a shoot with it this weekend before I sent it in for repair. I have to say, the High-ISO performance is phenomenal. ISO 1600 looks like 100 on my 7D.
So far so good with mine. The first chance I had to play around with it was indoors at night at home. High-ISO performance is amazing! Being an early adopter of the 6D, its more than possible there will be issues. I can accept that with a new camera. I live 20 minutes from their repair facility.
BTW- I believe that a person like me is a likely target market for this type of camera. This is my first full frame. In fact, I skipped crop sensor DSLRs all together after owning a bullet proof AE-1 Program and having access to a couple of T-90's from the film days. when film died a sudden and violent death, money went into point and shoot digital cameras and camcorders with the kids.
So I am going from an S100 to this. I would outgrow a T4i in a month, The 60D and 7D crops are going to be who knows what next year, and the 5Dmkiii is too much camera for me.
Good entry level full frame DSLR. If I grow out of this, maybe the 5D mark 4 or something.
+1. or a 1DX2 since you like skipping series models.
