It is a solid wide-angle prime for users of the company's GFX camera bodies. It's sharp wide-open and only gets sharper as you stop down a bit, it's built really well and it makes for a nice walk-around lens for all types of photography. Bokeh and sunstars aren't always the strongest, and ghosting artifacts with the sun in the frame can be a bit much. But we think its qualities outshine its shortcomings.
Imaging Resource Good build quality, cCompact and lightweight design, very good resolving power. It can't focus very closely, maximum aperture of f/3.5 can occasionally be limiting.
