Very glad you started this discussion, as I know a lens like this has been on your wish list for some time. Like you, I envision this being the astrophotography lens I've always wanted. Planning a trip to Easter Island toward the end of this year during the new moon and am thinking about the possibilities. May have to buy or rent this. Would love to hear your thoughts on specs and any real-world testing results you've seen.
Hiya proudgeek. Nice bright view finder will help focusing too. Can't wait. We have companies who give a decent return period so I'll do that instead of hiring.
