Viltrox has outdone itself by producing a 10x zoom lens designed for medium format sensors. With a large 60 mm image circle, this lens can comfortably cover camera sensors such as those found in the GFX 100S II and the Hasselblad X2D. What's even more impressive is that it has a constant aperture of T5.6.
Generally speaking, medium format zoom lenses tend to have variable apertures. This helps to keep the overall size of the lens relatively small. The downside is that at the longest end of the focal length, the aperture will be smaller than when shooting at the widest end.
This is what makes the new Viltrox lens quite unique; even with the huge focal range of 42–420 mm, the lens retains a constant aperture of T5.6. This is impressive because it's a constant t-stop, not an f-stop, meaning that regardless of what focal length you're shooting at, the exposure will remain the same.
Of course, this does mean the lens ends up being absolutely huge and weighs a whopping 16 kg, so it's probably not the best option for vlogging.
Nonetheless, it's still an impressive feat, although with a price tag of $100,000, it's probably not going to be flying off the shelves.
