This might be old news, but new to me. I purchased third hand gear, and started to investigate the YS-90DX strobes working with my Nikon D100 camera. I see that the small syn cable that goes from the camera shoe to the bulkhead is only a single pin circuit. This leads me to manual operation only, and would explain why a good percentacge of my photo's are overexposed, with the strobe settings at TTL. First thing I do next will be to operate my strobes in manual.
Now, I want to find and replace that single pin cable with a multi core cable so that I can make full use of the TTL stobes. I spent all day digging in cyber space with no luck. I found TTL convertors for D200 with issues as posted here on this forum.... yuk.....
Can I do what I think is possible, or forget it and stay manual. And if its possible, where can I find the info and cost. Comments please.
