Vivitar .43 Wide Angle Adapter on Sigma 60mm Art Lens on Sony A7 in Full Frame mode

Fooling about with the Vivitar .43 wide angle adapter once again. This time we have it on the Sigma 60mm F.28 Art Lens, it brings it down to 25.8 mm. changing it from a short telephoto to a medium wide angle prime lens. These Vivitar adapters are under $20 plus a few dollars for the ring adapters for various lenses. We have this on the Sony A7 and shooting it in Full Frame mode. We left the footage as is so you can see how much or how little depending on your point of view, that it vignette's We did a single point of light, the Neewer CN-160 LED directly on the A7 via the hot shoe and we used the Yellow/Orang filter thats included with it to warm thing up a bit. I'm truly amazed how well this screw on adapter works.
