Not European ( geographically actually the opposite, being based in New Zealand ๐ ) but not American either. I have very good experience with the Swiftpoint Z2 and can wholeheartedly recommend it! Not cheap an shipping takes a while, but its customizability is just awesome!
Hey, while not the cheapest lenses and only for aps-c, I'm really happy with my Tamron 17-70 f2.8 as kind of "always on" lens. For outdoor stuff and well lit scenes, I've got the Sony 70-350 f4.5-6.3. I'm totally happy with that setup, because it's just two lenses but covers a huge range of focal length.
I also own the Sigma 30mm and love it, good choice on that one! But due to the situations in which I mostly take photos, i prefer the zoom lenses ;)
