Well it sounds like they have at least 4 sold. Any late information of delivery. I hope it is this spring so we can get some good use out of them this summer.
Zeiss has two excellent lenses for underwater use coming in the next few months, the 50mm macro and the 12mm F/2.8. The Zeiss 24mm is the best of the NEX lenses I have used to date and I am sure these new lenses will be even better for U/W use. Cost is going to be the big issue, I would not expect to see these lenses sell for less than $1200.00 if not more. Not to be using a proper port for both would be a waist of an excellent lens.
