Here are some test shots I posted (D600) from ISO 1600 all the way up to 25600. The last sample is noisy (25600) but, look how well it cleans up in post using LR4's luminance slider.
No loss in detail. https://photography-on-the.net …p=15081225&postcount=8369
Hard to argue with those shots. I do not have a preference in ergonomics of one over the other. I've owned a D90 and a 60D. Looks like I'm heading back to the dark side.
