Review on MEKE 8mm f3.5 Ultra Wide Angle Manual Focus Rectangle Fisheye Lens for Nikon 📷 APS-C DSLR Cameras D500 D3200 D3300 D3400 D3500 D5200 D5300 D5500 D5600 D7100 D7200 D7500 by Robert Layne

is a really good lens and I like that it is sharp over the whole frame including the corners. What I don't like is that the ring you turn to focus the lens doesn't affect the outcome of the image. I wonder what happens when I use it to photograph things in the distance, or if something is out of focus, what will I do to bring it into focus?
