I recently got my hands on the Fujinon 35mm f2 WR lens for the X series of Mirrorless ILC's. So, on a rather dreary day I took it for a spin at the Sydney Gay and Lesbian Mardi Gras to test its metal and water resistance.
In hand the first thing you notice is its odd conical shape of the lens tapering from a small front element to a much wider base, which you do not see in other modern lenses. The build feels far more solid than any of the three lenses originally released with the X-Pro1. Also more solid than the 23mm f1.4 and 56mm f1.2 which I also previously owned.
Mounted to my X-T1 with face tracking I found the focusing, fast and snappy. Even with subjects moving towards me as I worked my way through the magical people who were part of the floats. Any missed shots were more user error than anything, even in the low available light I was working with. The weather resistance came in handy on the night too as there were intermittent showers towards the later end of the night.
I shot wide open at f2 most of the time with the lens and found the images sharp and provided decent separation between subject and background. Pictures straight out of the camera are decently contrasty in my opinion and adds to the lens' appeal. It's diminutive form on the an already small X-T1 body makes it an unobtrusive setup that allows you to get in there and not alarm your subject.
In using the lens I found that there were many thinks I liked about it but for me I kept being drawn back to the original 35mm. I am willing to forgo the slightly faster AF, smaller size, lighter weight and weather resistance for the faster aperture on the older one. I know this makes absolutely no sense but purely what I prefer for my shooting style.
For someone contemplating whether to buy this, I with no hesitation am happy to recommend it. For a relatively cheap lens, you get superior build, great optics and weather resistance. A worthy consideration if you are looking for a step up or addition to the kit lens.
