Any estimation as to how long it may be delayed now?
Well, given that we just hit a brick wall (after spending thousands of dollars on tooling), I can't really say.
I can tell you that this project was being done in parallel with Cinch MkII, which was slowing both projects down somewhat. Given that MkII will be out in a couple of weeks, 100% of my time will be devoted to re-engineering the QR system. We also have new materials and a new supplier that we didn't have before, and they combine to really expand on our capabilities (some of which will be on display with the MkII). With them on our side, I suspect that the QR will happen relatively rapidly and be way cooler than the hook design.
We will be posting a video in the next couple of days. The major bullet point of it is that you should *not* use *any* gate clip on your camera. This problem isn't just with the one we designed and tooled; it effects every off-the-shelf gate clip we tested. We happened to run into it because we perform really extensive testing.
If the hook gets wedged into the split key or opening you have it attached to, the gate can be pushed open right as the clip slides off. We've been running titanium gate clips on our cameras for months now as part of our evaluations, and never had a problem. It was only in the final rounds of extreme testing that we found the recipe for gate hook failure. Now that we've seen it, we can reproduce it with every one of the 5 different off-the-shelf gate hooks we have sitting around.
It is a rare failure. We've never heard of it effecting people (and lots of Cinch users have slapped gate hooks on their straps to get some sort of QR functionality). Even so, Luma is a business and that business is built on people trusting us to carry a *very* important piece of equipment. There is nobody out there who wishes I could sell these hooks more than me (they are really very cool, injection molded long filament carbon fiber that holds 250lbs!), but I cannot offer them for sale after seeing how easily a gate clip can fail.
If you are desperate for a QR system, the benchmark we are attempting to beat is the Swiss made Le Hook (http://www.lehook.co.uk). They are fantastic, they are strong, they are very trick... but they are also $40 for the pair.
