I don’t know if we should get tired of all of these cheap but small aperture lens or happy to have so many affordable, small options. I lean towards the latter.
We don’t have a price or release date for this lens yet, but it is full-frame, it would be reasonable to expect it to be available for the Sony E, Nikon Z, and L mounts. We should also expect reasonable performance in the center and questionable edges. F6.3 requires so much light that this lens is really limited. Think of it as an expensive lens cap, maybe. But we will be happy to be surprised.
For a little bit more money, you could buy a vintage 24mm F2.8 lens, but it obviously would not be as small. And for more money yet you could a third-party autofocus 24mm F2.8 lens.
