Alternative Phottix 0.85x and 1.25x viewfinders magnifiers for Leica M rangefinders

 

After I just came across this new USB 3 card reader from Phottix, I realized that they also sell 0.85x and 1.25x viewfinder magnifiers for Leica M rangefinders for $69 each (for comparison, the original Leica 1.25x costs $299):

Leica carries also a 1.4x viewfinder magnifier.
