Review on Samyang SYHD8M-C 8mm f/3.5 HD Lens with Detachable Hood for Canon by Somchai Tameeyasen ᠌

my model lacked focus at infinity. even with a closed aperture. just awful! I didn’t want to mess with the store, I sat at home for half a day with screwdrivers and fixed everything - I shifted the spinning ring for focusing along the internal thread by a centimeter - and lo and behold ! then collected several more times, but at least it was good that he achieved what he wanted. now the pictures are sharp even on an open bar, plus I made the minimum focusing distance smaller due to the fact that I increased the stroke of the focusing ring.
