V6IIs/RF60/A7rII/Adapted Lenses & TTL
When I use a native E-mount lens, TTL works brilliantly with my V6IIs and RF60s; however, as soon as I put on an adapted lens, I can't seem to get TTL to work right. The flash fires but it's nowhere near the right exposure.
Any hints/tips? Is there something I need to do to make this work? Is it hopeless?
