New Sony/Zeiss FE 16-35mm f4 OSS - thxbb12 - 09-30-2014
Quote:I think we can expect softer edges on this than on the Canon; with a complex wide zoom I doubt there's any real advantage to the shorter registration distance. And the Canon has a larger diameter, and is a little bigger. Allowing for equal optical expertise, and equal quality contraction and design, that ought to make the Canon a little better in the corners.
The interesting question is the extent to which Zony ought to try to make their lenses small. It's nice to have a small body, and of course there can be a few small prime lenses. But when you are going to have something as necessarily large as a full frame constant aperture zoom, maybe you would be better off having it a little bigger and better.
But I can see how opinions may vary..
In terms of FF mirrorless, what I would like to see is a system offering the following:
- Fast lenses with uncompromising IQ. Think f/1.4 for primes and f/2.8 for zooms. These would be large, heavy and expensive.
- Slowish lenses with great IQ, but as compact as possible. Typically f/2 to f/2.4 for primes and f/4 to f/5 for zooms. There would be pancake primes.
I really believe there would be a market for such offerings, but for some reasons no manufacturers seems to be wanting to release 2 ranges of lenses fulfilling 2 very different needs. Why is that?

TECHNICALLY, Sony could design lenses that simply keep a distance that doesn't compromise quality.
Olympus always suggested to use a telecentric design to overcome the sensor issues but honestly I am not a lens designer thus I am clueless about the problems of such an approach in full format lenses.
The other aspect is, of course, about expectations. Is it viable for a lens to have soft edges at that price point ? We are not talking about pocket money here.
However, let's see some hard data first anyway.

Where have you seen image samples showing soft edges, Klaus? Do you have a copy yet?
Samples I have seen so far look very promising and, considering the lacklustre FE 24-70, that is a relief.
I'm not sure why you are so positive about the Canon equivalent, as I have seen samples of that lens showing less than stellar edges. However, I don't think we can expect prime level performance from either the Canon or Sony versions - that is simply the reality in the field of UWA zooms.

Maybe you confused OOF edges with not sharp edges?

** edit: I also saw some wide open uncorrected samples, and they were pretty good.
