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?
