Dear DHW-Jhartje ,
I recently bought a Rolleiflex 1.4 AF longar & planned to use on my AFD 180mm F2.8 & PQ 300mm F4 .
But I found Lens comm. error displayed in my Hy6mod2 handle lcd screen with adnormal exposure , also, when coupled with PQ 300mm , sometimes , the shutter remain closed after exposured ( the exposure are adnormal for 80% ) , sometime the images files are darken & sometimes are overexposure .
I suspected that the firmware may be not updated for the 1.4 AF longar .
Should I sent back to Germany for updating firmware or any newer products(1.4X longar)
