The problem with the edges is a result incompatibility between the Leica design and A7R sensor ..not a function of a problem with the Leica lens . Try the same lens on a M240 and I am sure you would be pleased as almost every Leica user has been . The new Sony/Zeiss 55/1.8 was designed for the A7R sensor and should not have the smeared edge issue of some of the Leica and Zeiss M mount lenses .I've used the 50 Summilux ASPH on my A7r and have been sorely disappointed with the edges at wide apertures---with a $4000 lens!
I am seriously contemplating selling the Leica gear. It used to be "you couldn't go wrong owning Leica M lenses." The A7r has shown me that Leica has done some fine engineering with the digital M's covering the ray angle issue but they are losing the size and weight issue that has been their advantage.
