Yeah 100%. We stayed in the Lumix eco system for years using Canon lenses, and it worked. 3 years ago we finally bit the bullet and dropped like 15 grand into upgrading to Sony bodies and Sigma E mount lenses. That being said, we probably won't do a camera upgrade until these die on us, they more than accomplish anything we need from them. At this point, if we need another body, we can always pick up a used FX30 for like $1200 and it fits in perfectly with our FX6 and A7IVs.
