Without a doubt, the Laowa 10-18mm has quite interesting specifications, thanks to its ultra-wide zoom range and rectilinear design. The lens has a rather complex optical formula comprising of 14 elements in 10 groups, 2 of which are Aspherical and 1 is Extra-low Dispersion. The front element is coated with Laowa’s “Frog Eye Coating”, which works similarly to fluorine coating that we see on other modern lenses. To make the lens particularly attractive for including bright sources of light to create appealing sun stars, the lens has a 5-blade diaphragm (more on this later). A particularly interesting feature is the ability to use rear-mount 37mm filters, although as I reveal below, it is not a particularly useful feature to have for mounting thick polarizing filters.
