DF/ Aptus II 7 and M645 manual lenses problem ( color cast above 1/125e)

When using a vintage m645 lens on my DF / Aptus II 7 combo i have a strong magenta color cast with all speed above 1/125s ... it use to work properly before !

I've manage to borrow a grip in order to update the DF, i've install the last leaf capture in order to update the DM33... problem remains the same !

Lenses used :
M645 80 / 1.9
M645 80 Macro
M645 50 PC

i've open a support case : 131324

Does it happens to anyone here ?

I have the 80/1.9 and 50 PC and neither of these has exhibited this behavior with my DF & Aptus 65/P40+/P25+ or IQ backs that I've used with them.

Could it be a timing issue with the DF & non-AF glass and synching with the back? It would be interesting to try the back with any other cameras.

last news !

i was able to borrow an aptus II 8 and a DF to make a cross test...

the problem comes from my DM33 / aptus II 7, not from the DF !

David as you may have already been advised through the support case, returning to Firmware version 1.25 on the DF body will resolve this issue for you
