i guess that depends on whether you're used to a zoom lens, and if not, whether you have a preferred focal length you like to shoot at. i advocate for prime, always, for a lot of reasons, but to each their own. i've used exclusively the 35mm (50ish mm equivalent) for a couple years and really haven't missed shooting at other focal lengths. the lens they're offering is a fine lens, if it's what you want. it isn't WR but neither is my 35mm and i've never worried about it in light rain.
