The Novoflex QPL 270 Double-Sided Arca-Style Rail - 10.6" Long features an Arca-Swiss-style dovetail on either side, so you can attach it to a double-clamp system. For 3D applications, two cameras can be mounted to the long Q-Plate, one to each of the included 1/4"-20 screws, with horizontal positioning possible in order to adjust the interaxial distance between the cameras' optical centers.

Not only do the Q-series rails feature Arca-style profiles on either side, they also have 1/4"-20 & 3/8"-16 tripod mounting holes for direct attachment to a head or tripod. The rails serve as additional components for Novoflex's MultiMediaRig DSLR camera rigs (including Bluebird and uFly).

Q: 1. Will this adapter work on a 135 Elmarit- R 2.8 lens on a Sony a7iii body?

A: Yes this would enable you to use an R mount lens on the Sony A7iii body since the NEX mount was an E-Mount.

Q: 2. Can you use the lens aperture ring and the blue ring on the adapter in combination? Let's say, set your metering and shooting aperture on the lens, and then use the blue ring to flick it wide open briefly for the sake of precise manual focusing?

A: This will work. Be careful. If you use manual exposure, the viewfinder will probably become too bright to see clearly, because you would be overexposing.If you use aperture priority automatic exposure or auto iso mode, you need to remember to stop down before exposure. You may not see the difference because the camera will quickly adjust the exposure when you go wide open. You will see some fluctuation of intensity in the viewfinder.
