Viltrox has unveiled two new prime lenses for Sony, Fujifilm and Nikon APS-C cameras, the AF 75mm F1.8 EVO and AF 90mm F2.2 EVO.

I put the new Sony 100-400mm f/4.5 GM lens through its paces and found it to be a fantastic pairing with the new Sony A7R VI.

I took the Sony A7R VI and 400-800mm F6.3-8 super-telephoto zoom lens to my local nature reserve to try out bird photography.
