Viltrox 56mm f/1.7: Amazon / B&H Photo
Viltrox has released a lot of great autofocus lenses for X mount that often outperform similarly positioned first-party Fujinon glass so it shouldn’t come as a surprise that the Viltrox 56mm f/1.7 continues that tradition. When it comes to sharpness the Viltrox 56mm f/1.7 is impressively sharp even wide open on a 40MP body and it only has some slight pincushion distortion and vignetting that is autocorrected in the camera or your editor. The lens does have one weak point though which is autofocus performance, but that could improve with future firmware updates.
