Panasonic Leica D Summilux 25mm f1.4 ASPH

January 22, 2009

Hmm this lens is impressive..sharp at even f1.4 now tired will do a mini review later..

With this lens i could shoot nite scene at iso200 !!!!

Not convince i have a good copy of Panasonic Leica D Summilux 25mm f1.4 ASPH i purposely do a focus chart test to see if i have front or back focus. At f1.4 the DOF is just too thin and slight movement will change the focus point to another 2mm :)

I print out the test chart. Mount the Olympus E3 + Panasonic Leica D Summilux 25mm f1.4 ASPH on a manfrotto 190xprob tripod at 45 degree facing the focus point on the chart. Distance is 38cm which is the shortest focussing distance and i change the autofocus sensitivity to SMALL. Under normal mode the twin hair cross sensor will be acitivated and i dont want both of them to activate i just need one accurate one. Focus point on E3 is set to 1 point mid. ISO100 F stop F1.4.

I hereby certify this copy of lens is a good lens with no focussing issue...i just have to be careful with E3 twin cross hair AF sensor if i want pin point accuracy at f1.4
