Adapter for Sony a-mount lens to Sony e-mount camera

thingiverse

Adapter for Sony a-mount lenses to Sony e-mount cameras. The adapter opens the aperture blades of the lens. I designed this adapter to test which of my "old" a-mount lenses can handle the resolution of my new e-mount camera. The adapter isn't designed for permanent use! * * * #warning Handel your gear with care! Especially when you turn the zoom or focus ring of your lens because the adapter doesn't snap to the camera body nor the lens snaps to the adapter. * * * I tested the adapter with different lenses I own: <table> <tr> <td><b>Lens</b></td><td><b>works</b></td> </tr> <tr> <td>Tamron SP 24-70mm F/2.8 Di VC USD</td><td> yes</td> </tr> <tr> <tr> <td>Tamron SP AF 70-200mm 2,8 Di LD (IF) Macro</td><td> yes</td> </tr> <tr> <td>Tamron SP 90mm F/2.8 Di MACRO 1:1 VC USD</td><td> yes</td> </tr> <tr> <td>Tamron SP AF 70-300 F/4-5.6 Di VC USD</td><td> yes</td> </tr> <tr> <td>Tamron AF 18-200mm F/3.5-6.3 XR Di II LD (IF) Macro</td><td> yes</td> </tr> <tr> <td>Sony SAL1855 f/3.5-5.6 DT</td><td> yes</td> </tr> <tr> <td>Smyang 14mm F2.8 ED AS IF UMC</td><td> no</td> </tr> </table>
