I see alot of debate with LR not being able to handle 5D3 raws well..and ACR seems to be the same.
However, for some reason i can't install DPP on my macbook..just doesn't run and i don't have LR4..i only have Aperture…i wonder if Aperture also suffers the same "softness" as LR and ACR?
Did you try downloading the latest version of dpp for Mac from the Canon site? (version 26 I beleive)
