I have to alter development times depending on the era of lens I'm using. I can't say if this is due to the DR lens being lower contrast and higher resolution compared to the later Summicrons although this has been suggested by others. I question exactly what contrast means compared to a sharpnes. I find little difference in sharpness between the DR Summicron and the 1980's Summicron 50's, just different tonal renditions.
