you exactly pointed out the problem I am having
most of the HC lenses are harsh and inconsistent
for instance my 210mm performs much better when I try to shoot a tight head and shoulder shot, but must worse and harsh when shooting a waist up shot
I am not as experience as most of you here with decades of shooting, so I dont know what the problem is, I would guess it performs better in a limited focus distance
whereas the CF100 and CF180 which I find a lot more consistencies, and smoothness
I believe it isnt difficult to make sharp lenses, I keep bringing out Sigma and Tamron, but again they make very sharp lenses that hold up to or excel the original lens makers, but are they consistent, smooth, and reliable
what I am disappointed with is that the Fujiblad is so much more expensive than say Mamiya AF lenses, but we still see the inconsistencies within their design (like my 210mm example)
however as one of you have said, the lens might not be the very best out there but with proper technique, it should do the job well enough
I might have thrown in my decision too early with the 150mm and the 35mm (but I couldnt get sharp image with them on the 50MP back, tried stopping down to f8, f12, still dont see sharp image, what could I have done wrong?)

Fair enough, then I stand corrected. If the HC 150 is indeed sharper than the old 'C' lens, then it must be pretty sharp, because mine is killer. But then, I have tried the CF 180 which everyone raves about, and I wasn't that impressed. I think a lot of its apparent "sharpness" is really a kind of edgy micro-contrast, and I prefer the 150 because it is more pictorial, to my taste anyhow. The 'C' 150mm Sonnar is a wonderfully smooth and creamy lens - but that doesn't mean that it is soft. And I do disagree about CA - it does matter in B/W, just as in colour, because CA smears and broadens the edges of twigs and boat rigging against the sky, even in monochrome.
