We originally set out designing our prime lenses with a very high resolution target, extremely well corrected and a T1.8 target. Because we weren't sure if the final production units would make the aperture target, we advertised T1.9 to give ourselves some elbow-room.
I'm happy to announce that every single lens hit the original goal... the 25mm, 35mm, 50mm and 85mm are all true T1.8.
This may be a small thing, but I hope it points to our effort to be conservative in our announcements.
I am very proud of the lens team and what they have accomplished.
Jim
