The reason was relatively simple; photography cameras with higher resolutions began to see flaws that the photography company’s (and our existing) metrology […]

They’ve made lenses no one has ever tried before and not only succeeded, they made them amazingly good on the first try. Their quality control has become as good as anyone’s, better than most. And their repair […]
