Viltrox has been busying itself with full-frame Z-mount releases over the last year, building upon the core of its business which has been centered around APS-C. In fact, the last Fuji X-mount release was the “Pro” monikered 27mm f/1.2 that I reviewed in August 2023. The new 56mm f/1.7 sits at the opposite end of the spectrum, retailing at an extremely modest $139. It may be budget in price, but its performance is far from it.
