R5 Depth-of-Field preview Button

[jwolfastro]

I use a R5 with EF Lenses on an adapter (Vello). The Depth-of-Filed preview button does not seem to work, neither in hte VF nor on the screen. Does anyone know a solution?

Thanks, jwolfastro

I would assume that you may have an adapter problem.  Ask Vello about it.  Maybe they have a firmware update.
