I have been trying the Sony A7Rii camera with the Sony 50mm F1.8 and Tamron 28-200mm lenses.  It has taken some effort to learn the Sony menu system, but I think I have everything working the way I prefer.  One thing of interest to me is using the 42MP raw files in LR with my new computer.  So far, I have had no problems with them.  Another thing of interest is the ability to do severe crop zooming with the above gear so that I can minimize the number of needed lenses. 

Below are some examples of severe crop-zooming and resizing.  The original image first, followed by a crop from it.  The first set is from the Tamron lens at 200mm focal length.  The second set is from the 50mm prime lens with the picture made through the window.
