From what's reported so far, the big advantage of Zeiss 55 will be corner sharpness wide open. For those who need that, well price could be no object.
It's mentioned that mere mortal lenses can be similarly sharp in the center wide open and when stopped down. Early users are also reporting the Zeiss is perhaps too sharp for portraits, calling it "Portrait for perfect skin" lens, so for non-model adults I shoot, I would be stuck with less post-processing time with my L primes.
Yeah, that's another reason I don't get this lens. What's the target audience?
Corner sharpness in a portrait lens just isn't that important, typically. If anything, it is undesirable; many of the lenses that I've seen folks rate as being the best for portraits are some of the softest at the corners, because corner softness puts emphasis on the subject, who is typically at the center.
And for landscapes, 55mm is typically too narrow by a factor of two-ish, so I can't imagine that they intended those folks to buy it, either.
And no AF means that you won't realistically want to use it as your walking-around lens (not to mention that 55mm is a bit tight for that—IMO the sweet spot is somewhere in the 30-40mm range).
*shrugs* I guess they think somebody is looking for this lens. I just wish I understood who.
There are endless threads on this forum about the slow AF of the 85 1.2L II. This Zeiss lens have 248 deg rotation angle of focusing ring and I assume it carries (at least) as much glass. For you who understand this better than me, wouldn´t that end up being a very slow AF?
Probably, yes. They presumably built it the way they did so that it would be easier to manually focus accurately. Precise manual focus and autofocus speed are basically at odds with one another.
