Sigma DP Merrill not syncing
Hello there !
I recently bought the three DP Merrill cameras (DP1M, DP2M and DP3M) for second hand.
As you developped a Sigma TTL firmware (thanks for that btw !), I decided to buy the Cactus V6II transmitter with a RF60X to obtain both manual and TTL flash solution along with those wonderfull little Foveon cameras.
The V6II transmitter works fine as it receives all the cameras info when I shoot, the RF60X flash works fine as it gets triggered by the transmitter each and every time I shoot... but the flash doesn't appears in my pictures most of the time.
Here is an exemple :
I want to shoot indoor at night with few lights on
Sigma DPM at ISO 100, F2.8, 1/180 : picture is black without a flash.
I put my V6II transmitter on TTL, transmitter and flash on same channel and same ID, batteries are fully charged...
- 1st shot : flash triggers, black frame
- 2nd shot : flash triggers, black frame
- 3rd shot : flash triggers, black frame
- 4th shot : flash triggers and appears in the frame
- 5th shot : flash triggers and appears in the frame
- 6th shot : flash triggers, black frame
... and it continues like this : the flash does appears rarely and randomly without me changing a single setup on camera or on transmitter
I tried short or long range radio, changing radio channel... doesn't change anything
Sigma's firmwares are up to date, V6II and RF60X where updated a month ago, V6II does have the sigma firmware for TTL.
Sigma DP Merrils does have leaf shutter, so it shouldn't have sync issue (syncing with flash up to 1/2000 at f5.6 or 1/600 at f2.8)
It feels like the flash fires a moment before the shutter opens... Or after ? Radio delay maybe ?...
I don't understand why the flash doesn't appears on pictures, and why sometimes they magically appears !
Thanks in advance ! I hope someone can help me considering those sigmas are not so common
