I have never understood why some people prefer "fixed" B&W images from the camera, when so much B&W adjustment range and tweaking possibilities are available when shooting in RAW color. All possible color filter effects can be done in post with conversion software and plugins like Silver Efex. Pure B&W sensor does have certain advantages, but for me they are minimal compared to the convenience and limitless post processing possibilities offered by a RAW color file.
Absolutely; why would you throw away half of your possibilities? Without making parallel exposures of any scene it's a nonsense for anyone to state that a given system from an excellent camera maker is superior to another from the same source using the same optics, when all that the person really has going for him is opinion based on flexible memory and hope that can colour itself, chameleon-like, to suit the conclusion desired?
In the end, it's taking the train back to carrying two sets of film and/or bodies, just to cover your ass if you suddenly see something that screams for colour. If it screams for b/white, you can make it happen regardless. One-way options of that sort are hardly brilliant options unless you are absolutely colour blind or simply never use colour out of fetish-driven personality.
But hey, it's not my money!
P.S. All that said, if anyone wanted to give me any current Leica M-type as a gift, I'd very grateful!
