ALPA TC lens lock without hand grip

[jodad]

Anyone figure out a way to lock the lens in place on the TC without the hand grip’s safety lock?

I don’t know of any. I’ve been using Alpa STC for many years, which has no locking mechanism. It’s never been an issue. I can’t imagine a scenario where both flip locks would open inadvertently without intent.

That's what I thought too but on my SWA, I occasionally find that the front or back locks have sometimes moved upwards a little...
