Hi !
While waiting for my tech-cam to arrive, I have been playing with a Hassi 503 CX and a set of CF lenses (50mm FLE, 80mm CF, 150mm CF and lastly aquired of the bay, a 250mm CF). A pretty cheap camera & lens kit. I am using an IQ160 behind the Hassi, connected to the lens with a short sync cable (the other side of the cable being connected to one of the IQ's sync ports).
The system is really a joy to use. Nice focus feeling on the lenses, really nice and loud "clonk" sound when the shutter is pressed, nice viewfinder, and even winding the crank manually is fun. The lenses are pretty good, closed at f/11 or so, so it's a really nice (cheap) system before the Rodenstock lenses arrive.
I have only had one problem with the system and it's a syncing between lens-shutter and IQ-back.
When I started using the system, I connected the cable to one of the IQ sync ports, and it didn't work (back complained about no sync signal received). So for the heck of it, I tried the back's other sync port, and voila that worked. So I assumed one port on the back was defective, and I was going to bring the back to Phase for tests (there is still warranty left on the back).
Now I kept working like that for a while, using the 50, 80 and 150 mm lenses.
A few days ago, I received a "new" 250mm lens and wanted to use it. But it refused to sync. Tried to wiggle the connector on the lens side. Nothing. Then (again) for the heck of it, changed the sync cable to the other IQ-sync port (the one I thought was defective). And voila, on that port, the 250mm lens works ! Tried the other lenses on that port again. Nope, still no joy.
So it seems one IQ sync port works on the 250mm and not the other lenses. The other port works on the 50,80 and 150mm but not on the 250mm.
Strange, isn't it ? I need some sync Voodoo here !
I will take to back to phase for inspection before the warranty expires, but in the meanwhile, any ideas why this behavior happens ? Any other tests I could carry out to try to diagnose what's going on ?
Latest firmware on the IQ.
Thanks for the ideas. Perhaps I should just carry a rubber chicken for sync-port luck ?
