Of course now I’ve ordered mine it can’t come soon enough. I looked at all other possible options for non-native lenses and none made sense. I even looked at other compact but somewhat lenses with another body like the Nikon PF lenses and the Fuji 200 f2 but those didn’t really make much sense either. The good thing about getting the Sony lens is there a ton of options for how to use it with the teleconverters and different bodies (A9 for the best possible AF, A7RIII for cropping if subject is really far away or even A6500 if necessary).
Yes I’m also interested in that too. I ordered mine on January 12. The reason, apart from the huge cost, that I took a long time to decide on the purchase, was figuring out how to travel with it in terms of both flying and hiking along with my other gear. Is that a consideration for you?
