As we happened to be strolling through one of the company's online shops for our news 
about the new Nikon Z-mount 85mm lens from Viltrox we made a discovery that had passed us by until now.
We had already made good experiences with an EF-MFT SpeedBooster clone from Viltrox in the past and apparently the business is flourishing so well that Viltrox now even has seven focal reducers in its range.
But in addition to the typical representatives, there is also a hitherto unique EF to Z-mount adapter.
Since most Nikon Z-mount cameras (except for the Z50) are full-frame cameras, such an adapter does not make sense at first glance on full-frame cameras. This is because focal reducers reduce the image circle of a full-frame lens to the area of an APS-C/S53 sensor. And thus clearly shade the edge of a full-frame sensor.
However, there are also lenses whose image circle is somewhat larger, which is why you can also use them on such a focal reducer like a medium format lens. We had already written an article on this topic about 5 years ago (www.slashcam.de/artikel/Tips/Speed-Booster-an-Fullframe---Ein-Hauch-von-Mittelformat.html), which explains the subject in more detail.
By the way, the same technique is also possible with the new Canon Focal Reducer on an EOS R camera. And, of course, it has been possible for some time on the Sony E-mount, which also "works" with different sensor formats.
That's why we think it's particularly nice that Viltrox is now opening this little door for Nikon users as well. Fair enough. After all, it's almost Christmas.
