I was going to get the new Canon 24-70, but ... as that's been delayed for months, I was looking at the new Tamron 24-70.
It occurred to me that I'd have no way of knowing if it will work on the Scarlet (and if it would void the RED warranty, as it's not a Canon lens)?
But, if I put that lens on my Canon DSLR, it would work with all the features.
Why is that?
I guess I assumed that a chip in the lens would identify it's feature set in a manner that any compatible mount could detect.
Why does RED need to characterize a lens before it will work?
And, is this true in all cases?
