I like your collection the most and believe it makes the most sense-- probably because most similar to mine
WATE-16-18-21-- This is just outstanding especially with the Voigt close adapter (amazing what you can do)
Leica 28mm 2.8 Elmarit R
Sony/Zeiss 35mm 1.4
Sony/Zeiss 55mm 1.8
Voigtlander 75mm 2.4 and I have the 1.8 version as well but prefer the former (so small)
Leica 90mm Elmarit M
ApoTelyt 135
I also have the Sony 24-70 for walk around shooting.
I am considering the Batis 25mm and even selling the Leica 28mm and getting the Sony 28mm f2. The Leica 28mm R is just such a beautiful lens but again if traveling rarely makes it into the bag. Images are just so gorgeous. At some point would like to compare with the Sony 28mm. One of my major interests in the Batis 25mm is the ability for close up focus-- but with the WATE and close up adapter--- perhaps redundant.. Of course f2 and AF is so nice.. geez.. keep going back and forth on how to deal with this 25-28mm range.
I also am not using the Leica 90mm that often For travel I have the 75mm and 135 so figure that range is fairly well covered without the 90mm. If a good 200mm option becomes available perhaps 90mm would become more important and replace the need for the 135mm?
I tried a 70-200mm and thought the 200mm side of things was really quite good but the lens is much too big and heavy-- otherwise would go back to my Nikon system.
