Some cameras produce images that convert well to B&W. Others are only ok. The files from the Canon G1X are ok and don't come close to those from the Fuji cameras. The Fujis (X-E1 and the X100S) produce files that are a dream to convert in Nik SFXII.
The image above was processed in my normal workflow and it looks slightly oversharpened to me so I'm going to have to modify my workflow slightly for these images. Most camera files require a certain workflow because each manufacturer process them differently, even in raw format.
Another tip if you are using or planning on purchasing the Canon G1X, underexpose slightly. It does tend to overexpose and the whites will blow out for you unless you compensate. I think every Canon camera I've had tends to do this and it has become a matter of fact that I enter a negative EC on all Canon cameras that I use.
