Mamiya 645 and Phase One Lens Test

I decided to do some testing of my medium format lenses /Phase One Mount/ for my own use. But I think it is much better to share it with broader audience.

Test was done with following conditions:

Camera: Phase One DF

Digital Back: Leaf Aptus 75

Tripod: Manfrotto 055XPROB with Manfrotto 222 head

Self Timer: 3 sec

Distance: 1 meter /only 55-110 was shot at 1.5 meters/

Settings: ISO50, Manual Mode

Speed: 1/50 for f4 lenses, 1/100 for f2.8 lenses and 1/200 for f2.0 lenses

Focus Mode: Autofocus lenses were tested only with autofocus /S mode/. Manual focus lenses were focused with focus confirmation on camera.

Test Target: Distance to from camera was 1.0 meters and target have 3 lines with font sizes:1,2,3

All lenses were tested with 2 shoots, and from following lenses I have 2 copies each:

– Schneider Kreuznach 80mm LS f/2.8 ;  Mamiya 80mm AF f2.8 ; Mamiya 150mm AF f3.5

All copies have given same result.

List of all lenses:

AF-D:  Schneider Kreuznach 80mm AF LS f/2.8, Macro 120/4.0 MF D
AF lenses /not D/ were: 150/3.5 AF (2 copies tested), 80/2.8 AF (2 copies tested), 55/2.8 AF, 45/2.8 AF, 35/3.5 AF, 55-110/4.5 AF
MF: 24/4.0, 30/3.5, 80/1.9, 80/4.0, 110/2.0, 110/2.8, 140/1.8, 150/3.5
Haven’t test yet: 150/2.8 – too big minimum distance and 105-210/4.5AF as it didn’t work with my current body

And here comes the test results.
