This has been a hard lens to pin down, likely because it's still a long way off, with the expected announcement in August/September 2018 ahead of Photokina.
We reported last month that the lens was going to be a 50mm equivalent for APS-C and that it was going to be fast.
We rate this information in two parts.
The [CR3] Part:
The lens will have a focal length of 32mm and won't have IS.
The [CR2] Part:
The speed of the lens I haven't been able to nail down with 100% certainty as of yet, it'll either be f/1.4 or f/1.8 based on the conflicting information I have received.
Once I confirm 100% the speed of the lens, I'll obviously let you know.
