Is this for our cameras?
A-Mount to E-Mount FF Lens Adapter w/ TMT - Alpha DSLR Accessories Sony Store - Sony US (http://store.sony.com/a-mount-to-e-mount-ff-lens-adapter-w-tmt-zid27-LAEA4/cat-27-catid-All-A-Mount-to-E-Mount-Lens-Adapters?_t=pfm%3Dcategory)

For the full frame VG900, A7, A7R's may be?

That doesn't work with the EA-50 as it's an APSC sensor .. I have an idea Steve Digges has used the LA series adapters though... he might be able to help.
