According to the company, the Velvet 56 was designed with classic, mid-20th century portrait lenses in mind. As such, it has a metal lens barrel with a smooth, well-damped manual focus action. The Velvet 56 has a long turning radius from near to far focus giving it plenty of fine-focus control. We also found that when we used it with the electronic rangefinder feature of the Nikon D4s, the camera consistently told us it was in focus, when it was really wasn’t. Since there is no communication between the camera and the lens, you can’t really blame the Velvet 56 for this, but we warn you to be aware of this if you’re a Nikon shooter. We suggest bracketing your focus when first using the lens to get used to looking through the haze when shooting with the lens wide open.
