Unfortunately, no set date. The MKIII will be released in stages –Mark..How is the progress going on the Mk.111..Do we have a release date yet?
Also can you tell us what the difference will be over the MK.11.?
1. Injection Molded Plastic case that allows both future upgrades as well as backwards compatibility.
2. Focal correction or “astigmatism correction” element
3. CA correction where the new prisms will be made from two different types of glass that have been bonded together.
All of this takes time and money, and so a slow process when developing and funding a project like this yourself...
