5dm2 Portraits

I took a few shots of my parents and of Mike this past week. They aren't all great, in fact some are borderline bad b/c of all the noise but I want to share them anyway.


Mike took this one (and any other ones with me in them)
ISO 50 f/3.2 ss 1/125 5dm2 50mm1.8


ISO 1250 f/4.5 ss 1/100 5dm2 24-70L


ISO 25600 f/2.8 ss 1/100 5dm2 24-70L


Yes I know Mom's eyes are shut, and the noise is bad
ISO 25600 f/2.8 ss 1/100 5dm2 24-70L


Our tour guide ISO 4000 f/2.8 ss 1/100 5dm2 24-70l


ISO 4000 f/2.8 ss 1/100 5dm2 24-70L (I am a bit of a ham)


ISO 12800 f/2.8 ss 1/100 5dm2 24-70L


ISO 12800 f/2.8 ss 1/100 5dm2 24-70L


ISO 5000 f/2.8 ss 1/100 5dm2 24-70L

Does anyone else see the clear difference in quality I see from the shot with the 50mm 1.8 to the 24-70L?
