Build
The build is extremely minimal for this adapter. It is only 2mm thick and has a small profile. Its size was important in my decision, as I didn’t want a ‘beefy’ adapter like the Nikon FTZ. The Megadap is not going to add on any noticeable extra weight or size to your kit.
The circuitry is open, but Megadap states they have sealed the boards. I wondered how it would hold up in wet conditions so I emailed them and they stated that it would not affect the sealing of the camera or the lens. I have not tested the adapter in wet conditions, but I don’t trust that it’s totally sealed.
Other than that, this is a simple adapter. There’s a locking knob for the Sony E lens you attach, and it will attach to your Nikon Z camera just like a lens.
I have not had any issues with the adapter misfitting, in my experience, it is perfectly molded to Sony E mount and Nikon Z mount. I read stories about other adapters, like the Techart adapter, getting stuck on the camera – no horror stories like that with the Megadap.
Performance
We’re not buying the adapter for looks. We’re buying it for performance, for seamless integration between Sony E lenses and Nikon Z cameras.
Performance has been a mixed bag for me. I have successfully adapted and used numerous Sony lenses on my Z7, that includes the Sony 20mm f/1.8, 24-105mm f/4, 85mm f/1.8, and the 100-400mm f/4-5.6.
Everything that Megadap states will be supported is, except for lens stabilization. I found that lens stabilization does not work or works very poorly. I also found that the Z7’s IBIS does not work with the adapter. I had to be very careful while shooting at low shutter speeds because no stabilization system was supporting me.
Aperture control and autofocus do work. However, I experienced focus breathing and excessive hunting. Much more than native Nikon lenses (and the Sony lenses mounted on a Sony body).
For landscapes, that’s not really a big deal. I used manual focus a lot to ensure the focus was dialed in and the adapter worked great.
For wildlife, I think this adapter is totally unusable. It is impossible to track and you’ll be lucky to lock-on focus for any wildlife photography, in my opinion. The great news is that Nikon released a native Z 100-400mm f/4-5.6 so trying to adapt a Sony telephoto isn’t really necessary.
I also experienced connectivity issues. One adapter would lose connection any time I switched my camera to vertical orientation. It was frustrating. I since exchanged that adapter and the new one does not have that issue. So, it seems like there are quality control issues.
