iso 4000 on dp2m, judge for yourself

I love how everyone is saying that past iso400 or maybe 800 the dp2m turns to crap. Heres a quick snap (nothing scientific) at iso 4000 is pretty cruddy lighting basement lighting.

I used spp noise reduction, full chroma and banding, and the lowest for luminance. I then used topaz denoiser with photoshop. I would say its a fairly useable image.

-on a side note I'm bringing the dp2m on a shoot tomorrow with my studio lights. Im excited to see the outcome
