One more missing your images and wishing a faster than ever seen recovery.

Thank you! I'll try, honestly! No more choice, BTW!   LZ

This lens, contrary to 28-300, at 400mm, being wide open, still outresolving even 46MP Z7's sensor. The pic and crop.  LZ2019-04-07_7-1 by 2019-04-07_7-1-2 by longzoom, on Flickr]longzoom[/url], on Flickr

Next one at 400mm, 5.6, crop. In my experience, such the resolution is possible on mirrorless body Z7 only, today,  if hand held, of course.  On tripod, with MUP, it could be reachable, for D850,  but needs further research.  THX!  LZ
