Never-the-less, I need to address the idea of powder coating the titanium mount:
First, You have the best material for a lens interface with it's own natural protective passive oxide film and you want to powder coat it? (why)?
Second, powder coatings begin to deteriorate when exposed to uv rays after 5 to 10 years in normal environmental conditions. Not unusual to have a little extra UV on film sets. Titanium without any powder coating will deliver consistent results far longer.
Third, powder coatings are not easily applied as a thin, texture free layer - it has a tendency to achieve a smooth surface only with thicker particles - that means that film build-ups of greater than 50 μm may be required to obtain an acceptably smooth film. (That is why many manufacturers use powder coating - it allows them to hide surface defects on the metal)
Note: There are alternate methods such as powder slurry which can produce film layers under 30 μm, but again, why bother - titanium creates it's own protective layer when exposed to oxygen. I've run into air on most of my shoots - expect that to continue.
Fourth, if you begin adding a powder coating "layer", you add another dimensional variable to the lens mount interface. I'll trust precision CNC machining to a spray when it comes to delivering precise tolerances.
Fifth, why add another cost to the manufacturing process if there is no net benefit and only potential issues?
If anything (and this really belongs as a separate post) - I would prefer Stainless Steel as standard on EPIC, Aluminum as standard on Scarlet. That would be in line with differentiating one line from the other.
And yes, keep the Ti option there for EPIC owners.
