Hello all, I just got my 180-600mm yesterday and will spend the weekend testing it and giving it a once over. I've shot maybe 4-5 photos out of my front yard so far. I'm starting this to provide my thoughts on the lens as I test it this weekend. On Sunday, I'm going to Cape Canaveral to use it for the SpaceX Starlink 6-12 launch. I'll post some shots for you to review. Below is the only one of interest in that it shows how crisp this lens is, even a 600mm. I saw on a YouTube that the narrator was concern the pre production model was a little off at 600mm. I think you will find with this production model...its just fine.
