Lumix s1r hi res mode - sharpest lens?

[Bernard Wolf]

I have the Panasonic s1r and have played with the hi res mode and can see it's potential to produce incredibly detailed images. I have the Sigma 14-24 Art zoom and the Panasonic 24-105 that came with it.
I wonder if anybody here has experience with sharper primes and using them with the hi-res mode and can recommend the best L-mount glass to extract all that great resolution?

My guess would be that a Sigma telephoto prime or a Leica APO-Cron would be the sharpest lens choice. The LUMIX S Pro zooms are significantly sharper than the 24-105. Personally I don’t use the pixel shift modes so I haven’t given it much thought.
