Title: Contax 645 Flash Sync Problem w/P30
Post by: benedmonson on May 06, 2007, 11:27:14 pm
I have been having a problem every once in a while firing my strobes from my Contax 645 w/P30 back. I always shoot with pocket wizards, when the problem occours I can generally switch to my stand by cable and the will fire again. After a while I can switch back to my pocket wizards and they will work fine. Today during a long shoot both the wizards and my cable failed. I did several test and the cable was fine, but the camera wouldn't fire the strobes. I disconnected everything from the camera a even put in fresh batteries in the back and the camera and it still wouldn't work. After shooting a set with natural light I then tried the pocket wizards again, and this time they worked perfectly the rest of the day. If I had another body I could test it, I'm thinking the problem is with my Contax body. Has anybody ever had this problem. I have no time to send it to service as I'm shooting everyday. I will be ordering another body, but in the meantime any comments????

Cheers,

Ben,

Are you using the Wizard directly on the hot shoe of your Contax w/ no cables? Have you tried to cable the Wizard to your DB and bypass the hot shoe?

Thank you,

I also shoot with a Contax 645, P30 and Pocketwizards.   I've never had any problems.

I shoot everyday with this combo too and have only had this problem a handful of times. Just can't figure out what is making it happen. Was hoping somebody else had experience with it. Chris I'll try the P30 flash sync next time. I always use the pocket wizard mounted on the hot shoe.

I know it sounds obvious, but clean all the contacts well with alcohol. I actually use the Quantum freewire system (they had a better Contax cable) and works fine.
