from a fashion show i shot recently --- both with the 85mm 1.8...one on cam flash, one off camera with shoot through umbrella
I like your lighting and what what you do with the 85 1.8. Are those hot pixels, though, to the top right of the models' heads?
They do look like hot pixels, two clusters of them.
I had to return two 5DIII bodies with hot pixels at low ISO. It was very disappointing, but I finally got a perfect body the third time.
The experience has left me concerned about Canon quality control.
I do believe you are right...crap!!!!
Return the body is you can. Or send it to Canon for repair.
You can also do the manual dust cleaning. This remaps the stuck pixels to nearby pixels. I did this with the first body I bought, but it soon developed another couple of red pixels, so I returned it (was less than 30 days old).
