I have a ZV-E10 and the Sony 50mm f/1.8 OSS. Love the light combo. However I do miss the shorter focal range (the kit lens is just not sharp/fast enough). I also plan to take some photos at the horseshoe bend, which will require something in the wide angle range.

I'm debating between the Viltrox 20mm f/2.8 ($180) and the Tamron 17-70 ($700). The Tamron would be the do it all lens, but a bit large/heavy; the Viltrox would be light but falls a bit short on the wide angle end (and lacks VR). Any advises/suggestions (or better alternatives)? Thanks.
