Just purchased a 150 lens (crome), to compliment my Hasselblad (500c) with a normal (80) lens. I am reading that this particular lens is great, others claim it's on the soft side. My 80 is as sharp a lens as I have seen, can I expect the same from the 150, or should I return it? Looking for comments on the 150 as far as sharpness...(posted 8724 days ago)
