Ronnie, you'll see towards the end of the photonet post that I also included central resolution samples of the 50/2 Summicron and pre-asph. 50/1.4 Summilux, both of which closely matched the asph. Summilux, with the Summicron having a very very slight edge. All lenses tested gave perfect RF focus at infinity so I doubt the RF cam was off on the Planar. The slight softness with the Planar was repeatable with a second roll when I retested and bracketed focus to determine optimal resolution. The only explanation I could come up with involves the position of the lens' optical cell with regards to the position of the RF cam. I believe Puts inferred the back focus issue was not insignificant but did not say by how much. Interestingly, the Planar had better resolution than any of the Leica lenses at 0.7 meters.
