Thanks to the Depth of Field Calculator on the WEB, I present.

 

M9, focused at 10 Feet...Wide Open..circle of confusion 0.03mm

                          Near   Far      Total DOF     

50mm Noctilux  9.65     10.4     0.72 Feet

50 Summilux     9.52     10.5     1.02        

75 Summilux     9.78     10.2     0.45

75 Summicron   9.69     10.3     0.63

90 Summicron   9.79     10.2     0.44

 

Bob is correct.. the 75 Summicron has a narrower DOF than a Noctilux.

 

At 5 Feet...

50 Noctilux         4.91    5.09     0.18 Feet     

50 Summilux      4.88    5.13     0.25

75 Summilux      4.95    5.06     0.11

75 Summicron    4.92    5.08     0.15

90 Summicron    4.95    5.05     0.11

90 Elmarit (2.8)   4.93    5.08     0.15

 

To make this more inch related.. 0.1 feet = 1.2 inches

 

Basically, focus carefully, my friends...
