What you need, then so is such an adapter. One can spend a lot or just for little money. Here we have the little variant. All the more astonishing the heavy, metallic and high quality translucent processing. On my Sony system cameras bayonet connector fits perfectly, good locks and rotates with the right resistance again gently out.
When Lens connection you have to be prepared for anything. The M-terminals were screw and is very large here: screws! You already frickelt be a wolf to turn the glass fixed to the adapter - but my brother, once a proud analog Praktica owners assured me thatit so and not have to be different. Okay, I take that as an ancient charm still love to go, but why sit all lenses upside down on the adapter, so the Aperture setting down?
In this case, receives a small enclosed Allen wrench his grand entrance. Three (3) small screws it is namely the front adapter ring to solve the internal thread within the adapter for fine adjustment of the lens to adjust. This works great and behold, everything is in its place! In periods of complete digitization and electrification here strikes back good old mechanical craftsmanship. And that fits so well for these old manual lenses with so much charm.
Everything else must now do the photographer - since then electronic or digital does not help the way also.
