My "new" Heliar had an unreliable PC port, and I had it fixed. When I picked it up from my local camera store, I was informed that using a cable to trigger the flash causes much more wear on the PC port than using the PC port to trigger a wireless trigger. Apparently voltages required to trigger via cable are higher. So, is a wireless trigger easier on the PC port than using a cable?
This is the second time I've had a PC port fail - first was tripping on a cable, second lens came with a faulty port -, and they're pretty expensive to get repaired, so I'd be interested to maximize longevity of the port. I've used wireless as a backup, and wired as my main trigger - if what he said is true I should switch the priority around.
