Heather and Mat from Mirrorlessons.com have written a review on the Vector, Cascade, Speed and Regatta straps!
Heather brings up the point of the Speed strap being a bit long, and non adjustable (currently working on a remedy through new design for that!) for her which didn't suit her needs or style, but really liked the Vector and Regatta straps.
If you've not stumbled across Mirrorlessons.com before, I'd suggest doing so. They're great folks, and longtime friends that I've collaborated with over on my photography review blog for years.
An honest, and appreciated review in real world terms. Have a read HERE.
Thanks to Heather and Mat!
Happy shooting, and shoot nauti.
