Finally, Zhong Yi Optics announced a speed booster (they are calling it Turbo Adapters) for Nikon mirrorless cameras. You can use this speed booster on the Nikon z50 camera as well as the Nikon z FC camera. They have announced three of them. So, now you can use your F-Mount lens as well as EF Lenses with DX Mirrorless cameras, the third one is for Mount42 (The M42 lens mount is a screw thread mounting standard for attaching lenses to 35 mm cameras, primarily single-lens reflex models. source wikipedia)
Now the big question is what the speed booster will do to your camera what new features will be present inside the speed booster
- One of the most important things is that it reduces the crop factor, so you can easily use your Nikon f Mount lenses with a DX mirrorless camera system without facing any crop. That’s great news.
Now I read it very clearly since it’s one of the most important features of any Speed booster that you will use in your DX mirrorless camera
- With the help of a new speed booster, you will get a clear one-stop aperture advantage with the lens you are using.
For example, you are using a 50mm 1.8 of mount lens in your DX mirrorless camera. While using the 50mm f 1.8 lens you will not face any 1.5 X crop factor. So, you will have a bit wider coverage and your camera will act as a full-frame camera since more light is getting into the sensor with the help of a speed booster. And not only that the resulting aperture will be reduced to f 1.4 to 1.2.
The only big issue is the speed booster doesn’t have AF contact pins, which means you will not able to use the autofocusing mechanism of your lens while using this speed booster. So you can work with the old age manual f Mount lenses very effectively year but unfortunately, the autofocusing mechanism will not work with the latest lenses.
