From Jim in Delaware:
I have been using the for a month now and absolutely love them! Colors pop and details are clear.
I am also a big fan of the focus wheel, which is well positioned and large. The sensitivity of the focus wheel took a few days to get used to, but once I did, I have really enjoyed the quickness of finding the proper focus.
The one improvement I would suggest to Zeiss would be to provide lens caps that hold onto the body more firmly. The supplied objective covers pop out with the slightest movements.
