Over Exposed
If it's any help, whilst I know you can only glean so much from a JPG view on a screen, these are shots I took that I think typify the differences between the lenses I mentioned.
It's worth noting that I often like to isolate my subjects by shooting at wide apertures (often fully open) so a lenses OOF characteristics are quite important to me.
Leica 35/1.4 Summilux ASPH shot on M8
Zeiss Biogon 28/2.8 shot on M8 (slightly cropped)
(uncropped but not wide open)
Zeiss Planar 50/2 (cropped) Hexar RF
(uncropped) Hexar RF
(uncropped) M8
And finally a couple of test shots I did a 35/1.2 Nokton and a 35/.15 Canon (with identical/minimal processing) both on M8 shot wide open. I found the difference quite surprising.

Canon 35/15
