He just shared his very first impression about the lens. Here they are:
all metal lens hood
pretty small but long. Would feel a bit long on something like an X-E camera
it can’t cover full frame, which is why size is contained (compared to the Viltrox 85mm f/1.8, which also fits on full frame cameras, hence the lens is bigger than it would be, if designed only for APS-C)
autofocus: it’s good. Single AF is quick and snappy. It’s much more quiet than the XF35mm f/1.4.
continuous AF seems to work well too. At least in bright conditions, which is where he tested it
aperture ring is step-less. He’d have preferred 1/3 stop clicks on aperture ring. It does not feel very smooth, unlike the focus ring, which is smooth like butter.
nice image quality. Fringing is under control but present. Vignetting behaves very well. Decently sharp at f/1.4 and of course much sharper when stopped down
it can easily catch haze when shooting strongly backlit subjects (also Viltrox 85mm f/1.8 behaves like that)
He then compares it to the Fujinon GF63mm f/2.8 mounted on the Fujifilm GFX 50R as well as to the cheap Canon 50mm. The Viltrox 33mm f/1.4 was the fastest focusing lens in the test.
We remind you that Tokina will also launch a 23mm/1.4, 33mm f/1.4 and 56mm f/1.4 lens in 2020, as we reported here. They look like re-branded Viltrox lenses. It will be interesting to see, though, if also the Tokina lenses will have a clickless aperture ring, too.
